Practice Free HPE7-A02 Aruba Certified Network Security Professional Exam Exam Questions Answers With Explanation

When HPE Aruba Networking ClearPass Device Insight (CPDI) shows a recommendation for "Windows 8/10" with 70% accuracy for a generic device cluster, it means that CPDI has detected that these devices match about 70% of the system rule criteria for defining "Windows 8/10" devices. This percentage indicates the confidence level based on the observed characteristics and behavior of the devices, helping administrators understand the likelihood that these devices are indeed running Windows 8 or 10.

To enable HPE Aruba Networking ClearPass Policy Manager (CPPM) to process Syslog messages from a Palo Alto Next Generation Firewall (NGFW) and quarantine clients involved in security incidents, you need to configure the Palo Alto as a context server on CPPM. This setup allows CPPM to receive and understand the context of the Syslog messages sent by the Palo Alto NGFW, enabling it to take appropriate actions such as quarantining clients.

1.Context Server Configuration: Configuring the Palo Alto NGFW as a context server in CPPM ensures that CPPM can process and respond to Syslog messages effectively.

2.Security Incident Response: By understanding the context of the Syslog messages, CPPM can automatically trigger actions like client quarantine based on security incidents detected by the NGFW.

3.Integration: This integration enhances the overall security posture by enabling coordinated responses between the firewall and CPPM.

Integration of CPDI and CPPM for Zero Trust:

CPDI (ClearPass Device Insight) identifies and profiles devices and applications on the network.

CPDI can tag devices based on their behavior or detected applications.

CPPM uses these tags to enforce policies, such as quarantining clients that violate security rules (e.g., using prohibited applications).

Option Analysis:

Option A: Incorrect. CPPM does not inform CPDI about role assignments; CPDI provides device context to CPPM.

Option B: Correct. CPDI tags clients, and CPPM uses those tags to enforce quarantine or other Zero Trust actions.

Option C: Incorrect. Custom fingerprint definitions are not part of this integration.

Option D: Incorrect. CPDI provides information about devices, not user identities.

In the exhibit, the HPE Aruba Networking Central settings for the 9x00 gateway show that traffic inspection is enabled, and the gateway is set to operate in IDS (Intrusion Detection System) mode with the fail strategy set to "Block". This configuration means that the gateway will drop traffic if it matches a rule in the active ruleset.

1.Active Ruleset: The ruleset version 9861 is active, and the gateway is configured to automatically update the ruleset daily.

2.Traffic Matching Rules: When traffic matches a rule in the active ruleset, it is flagged as suspicious or malicious.

3.Block Mode: Since the fail strategy is set to "Block", any traffic that matches a rule in the active ruleset will be dropped to prevent potential threats.

1. IDPS Mode Configuration Overview

The exhibit shows the HPE Aruba Networking Central settings for the Gateway IDS/IPS configuration:

Mode: Configured for Intrusion Prevention System (IPS), meaning that the gateway actively blocks traffic identified as threats.

Fail Strategy: Configured to Block, meaning that if the gateway cannot determine the traffic's nature due to a system issue, it will block the traffic.

Ruleset: The gateway uses a predefined set of intrusion detection/prevention rules (ruleset version 9861), which is updated automatically every day.

2. Traffic Evaluation in IPS Mode

In IPS mode, the gateway analyzes traffic against the active ruleset:

If traffic matches a rule in the ruleset and is deemed malicious, the gateway will drop the traffic as part of its prevention mechanism.

The ruleset defines specific conditions (e.g., signatures of known attacks, protocol anomalies) under which traffic should be blocked.

3. Explanation of Each Option

A. Its site-to-site VPN connections failing:

Incorrect:

Site-to-site VPN connection issues do not directly trigger traffic drops under IDPS settings.

IDPS is focused on detecting and preventing malicious activity, not general connectivity issues.

B. Traffic matching a rule in the active ruleset:

Correct:

In IPS mode, the gateway drops traffic that matches any predefined rules in the active ruleset.

For example, if traffic matches the signature of a known exploit or attack, it is immediately blocked.

C. Its IDPS engine failing:

Incorrect:

The fail strategy determines how the gateway behaves in the event of an IDPS engine failure.

In this case, the fail strategy is set to Block, but this applies only if the engine itself fails, not as a proactive traffic drop mechanism.

D. Traffic showing anomalous behavior:

Incorrect:

While anomalous behavior may be logged or flagged, it does not necessarily lead to traffic drops unless it matches a specific rule in the active ruleset.

Anomaly detection alone is not sufficient for IPS action without explicit rule matches.

Final Outcome:

Traffic is dropped only when it matches a rule in the active ruleset, ensuring targeted prevention of malicious activity.

Best Practices for Configuring Fail Strategies in IPS Mode.

To ensure that HPE Aruba Networking ClearPass Policy Manager (CPPM) applies tag-based rules to a client immediately after learning the client has that tag, verify that both 802.1X services have the "Profile Endpoints" option enabled and an appropriate Change of Authorization (CoA) profile selected in the Profiler tab. This setup ensures that when a device is profiled and tagged, CPPM can immediately enforce the updated policies through CoA.

1.Profile Endpoints: Enabling this option ensures that endpoint profiling is active, allowing CPPM to gather and use device information dynamically.

2.CoA Profile: Selecting an appropriate CoA profile ensures that CPPM can push policy changes immediately to the network devices, applying the new rules without delay.

3.Real-Time Enforcement: This configuration allows for the immediate application of new tags and associated policies, ensuring compliance with security requirements.

ClearPass Device Insight Integration:

To integrate ClearPass Device Insight (CPDI) with ClearPass Policy Manager (CPPM), you must enable the Insight feature in the CPPM server configuration settings.

This ensures CPPM can share and receive profiling data with CPDI for device identification.

Option Analysis:

Option A: Incorrect. Root CA certificates are not required for this integration.

Option B: Correct. Enabling Insight on CPPM is essential for the integration to function.

Option C: Incorrect. WMI, SSH, and SNMP are not part of the CPDI integration prerequisites.

Option D: Incorrect. The Data Collector token is relevant to Aruba Central, not CPDI integration.

What is Zero Trust Security?

Zero Trust Security is a security model that operates on the principle of "never trust, always verify."

It focuses on securing resources (data, applications, systems) and continuously verifying the identity and trust level of users and devices, regardless of whether they are inside or outside the network.

The primary aim is to reduce reliance on perimeter defenses and implement granular access controls to protect individual resources.

Analysis of Each Option

A. Companies must apply the same access controls to all users, regardless of identity:

Incorrect:

Zero Trust enforces dynamic and identity-based access controls, not the same static controls for everyone.

Users and devices are granted access based on their specific context, role, and trust level.

B. Companies that support remote workers cannot achieve zero trust security and must determine if the benefits outweigh the cost:

Incorrect:

Zero Trust is particularly effective for securing remote work environments by verifying and authenticating remote users and devices before granting access to resources.

The model is adaptable to hybrid and remote work scenarios, making this statement false.

C. Companies should focus on protecting their resources rather than on protecting the boundaries of their internal network:

Correct:

Zero Trust shifts the focus from perimeter security (traditional network boundaries) to protecting specific resources.

This includes implementing measures such as:

Micro-segmentation.

Continuous monitoring of user and device trust levels.

Dynamic access control policies.

The emphasis is on securing sensitive assets rather than assuming an internal network is inherently safe.

D. Companies can achieve zero trust security by strengthening their perimeter security to detect a wider range of threats:

Incorrect:

Zero Trust challenges the traditional reliance on perimeter defenses (firewalls, VPNs) as the sole security mechanism.

Strengthening perimeter security is not sufficient for Zero Trust, as this model assumes threats can already exist inside the network.

Final Explanation

Zero Trust Security emphasizes protecting resources at the granular level rather than relying on the traditional security perimeter, which makes C the most accurate description.

To ensure that the AOS-CX switch properly assigns the "employees" role when using CPPM (ClearPass Policy Manager) as the RADIUS server, you should configure a RADIUS Enforcement profile on CPPM with the Aruba-User-Role VSA (Vendor-Specific Attribute) set to "employees". This configuration ensures that when an endpoint authenticates, CPPM sends the appropriate role assignment to the AOS-CX switch, which then applies the corresponding policies and VLAN settings defined for the "employees" role.

To better interpret the packets shown in the Wireshark capture, you should choose to decode UDP port 5555 packets as ARUBA_ERM and set the Aruba ERM Type to 0. This configuration will allow Wireshark to properly decode and display the Aruba-specific encapsulated remote mirroring (ERM) packets, providing a clearer understanding of the traffic.

1.Decoding Protocols: Selecting the correct protocol decoding in Wireshark ensures that the captured packets are interpreted correctly, displaying the relevant information.

2.Aruba ERM: The packets in the capture are likely encapsulated remote mirroring (ERM) packets specific to Aruba, which require proper decoding settings in Wireshark.

3.Clear Interpretation: By setting the Aruba ERM Type to 0 and decoding the packets as ARUBA_ERM, you can view the encapsulated data accurately.

When using OpenSSL to obtain a certificate signed by a Certification Authority (CA), you should submit the Certificate Signing Request (CSR) file, which is file1.pem, to the CA. The CSR contains the information about the entity requesting the certificate and the public key, but not the private key, which is in file2.pem. The CA uses the information in the CSR to create and sign the certificate.

1.CSR Submission: The CSR (file1.pem) includes the public key and the entity information required by the CA to issue a certificate.

2.Private Key Security: The private key (file2.pem) should never be sent to the CA or shared; it remains securely stored on the requestor’s server.

3.Certificate Issuance: After the CA signs the CSR, the resulting certificate can be used with the private key to establish secure communications.

Access to the Onboard portal is controlled by a dedicated Pre-Auth service in ClearPass Policy Manager:

The “ClearPass Onboard Service Pre-Auth” service defines which authentication sources (e.g., AD domain, local DB, guest) are used when users log into the Onboard web portal.

To restrict access to domain users only, you edit this Pre-Auth service to use only the Active Directory auth source (and appropriate authorization checks, such as group membership).

Exam and configuration references for ClearPass Onboard clearly identify the Onboard Pre-Auth service as the place where you control who can log into the Onboard portal.

Network Settings and Provisioning profiles in Onboard govern SSID, profiles, and device configuration, not portal user authentication.

The 802.1X services for wireless control network access after onboarding, not login to the onboarding portal itself.

Therefore, to limit the portal to domain users, you should edit the ClearPass Onboard Service Pre-Auth service on CPPM ? Option B.

802.1X Authentication Modes:

Client Auth-Mode: Requires each connected endpoint to authenticate individually using 802.1X.

Device Auth-Mode: Allows the port to authenticate a device, such as an AP, as a whole. This mode works when the device bridges traffic (e.g., AP bridging SSID traffic).

AP Role Configuration:

Since the AP bridges traffic from multiple clients, you must configure the AP role to use device auth-mode.

Meanwhile, the ports on edge switches can remain in client auth-mode to enforce 802.1X for individual client connections.

Option Analysis:

Option A: Correct. This ensures the AP itself authenticates with device auth-mode, while edge ports remain in client auth-mode.

Option B: Incorrect. APs require device auth-mode for bridging, not client auth-mode.

Option C: Incorrect. Device auth-mode on all ports would not meet the security policy for clients.

Option D: Incorrect. Leaving all ports in device auth-mode does not meet the policy for 802.1X on edge ports.

To support the requirement for HPE Aruba Networking ClearPass Policy Manager (CPPM) to have HTTP User-Agent strings for profiling devices, you should add the CPPM server's IP address to the IP helper list in all client VLANs on routing switches. This configuration ensures that DHCP requests and other relevant client traffic are forwarded to CPPM, allowing it to capture HTTP User-Agent strings and use them for device profiling.

1.IP Helper Configuration: Adding CPPM to the IP helper list ensures that the switch forwards DHCP and other client traffic to CPPM, enabling it to gather necessary information for profiling.

2.User-Agent Strings: By receiving client traffic, CPPM can analyze HTTP headers and capture User-Agent strings, which provide valuable information about the client's device and browser.

3.Profiling Support: This approach supports the comprehensive profiling of devices, allowing CPPM to apply appropriate policies based on detailed device information.

When deploying a virtual Data Collector for HPE Aruba Networking ClearPass Device Insight (CPDI), it is essential to ensure that the correct virtual port is connected to the designated VLAN. In this case, VLAN 101 is used to receive the IP address and connect to Aruba Central. The best practice is to use the virtual port with the lowest port ID. This is typically the primary port used for management and network connectivity in virtual environments, ensuring proper network integration and communication.

1. Understanding CPDI Risk Score and Posture Analysis

The Risk Score in ClearPass Device Insight (CPDI) is a numerical value representing the overall risk level associated with a device. It considers factors such as:

Posture Assessment: The device's compliance with health policies (e.g., OS updates, antivirus status).

Security Analysis: Vulnerabilities detected on the device, such as known exploits or weak configurations.

A Risk Score of 90 indicates a high-risk device, suggesting that the posture is unhealthy and vulnerabilities have been detected.

2. Analysis of Each Option

A. The posture is unknown, and CPDI has detected exactly four vulnerabilities on the device:

Incorrect:

The posture cannot be "unknown" because posture assessment is enabled in the settings.

CPDI does not explicitly indicate the exact number of vulnerabilities directly through the Risk Score.

B. The posture is healthy, but CPDI has detected multiple vulnerabilities on the device:

Incorrect:

A Risk Score of 90 is too high for a "healthy" posture. A healthy posture would typically result in a lower Risk Score.

C. The posture is unhealthy, and CPDI has also detected at least one vulnerability on the device:

Correct:

A high Risk Score of 90 indicates an unhealthy posture.

The presence of vulnerabilities (based on Security Analysis being enabled) further justifies the high Risk Score.

This combination of unhealthy posture and detected vulnerabilities aligns with the Risk Score and configuration provided.

D. The posture is unhealthy, but CPDI has not detected any vulnerabilities on the device:

Incorrect:

If no vulnerabilities were detected, the Risk Score would not be as high as 90, even if the posture were unhealthy.

Final Interpretation

From the configuration and Risk Score provided, the device's posture is unhealthy, and at least one vulnerability has been detected by CPDI.

HPE Aruba Central Live Monitoring:

Aruba Central provides real-time Live Monitoring of network devices, including:

Application usage statistics.

Trends and changes over time for specific devices.

This information is presented in a clear and easy-to-read format, making it ideal for examining changes in application usage over different time ranges.

Option Analysis:

Option A: Incorrect. ClearPass OnGuard monitors endpoint compliance (e.g., antivirus, OS version) but does not analyze application usage.

Option B: Correct. Aruba Central's Live Monitoring page is specifically designed for this type of analysis.

Option C: Incorrect. ClearPass Insight generates endpoint security reports but does not track application usage.

Option D: Incorrect. ClearPass Device Insight (CPDI) focuses on device profiling and identification, not continuous application monitoring.

802.1X Service Rules:

Service rules define the criteria for when a specific service applies (e.g., wireless vs. wired authentication).

For wired 802.1X authentication to work properly, the service rules need to differentiate between wireless and wired connections.

If you copy the wireless service, the rules likely still match wireless-specific criteria. These must be updated to include wired-specific conditions (e.g., NAS IP or port types).

Option Analysis:

Option A (Role mapping policy): Role mapping policies determine user roles based on attributes but are not critical for differentiating wired vs. wireless.

Option B (Authentication methods): Authentication methods (e.g., EAP) remain the same for both wireless and wired 802.1X.

Option C (Authentication source): Authentication sources (like AD or internal database) do not need to change.

Option D (Service rules): Correct. Updating the service rules ensures the new 802.1X service applies specifically to wired connections.

HPE Aruba Networking SSE is a cloud-delivered Security Service Edge platform that provides secure web gateway, ZTNA, CASB/DLP, and cloud firewall functions. Threat detection for remote web browsing relies heavily on full traffic inspection, including SSL inspection, URL filtering, and malware scanning.

In Aruba SSE deployments that protect web access from campus/branch or remote users, you:

Integrate the on-prem gateway or AOS-10 environment with SSE using an external web profile, which defines how traffic is sent to SSE.

Within that profile, you enable SSL inspection so that SSE can decrypt and inspect HTTPS traffic, allowing advanced threat detection, DLP, and malware scanning.

Option A: Custom file security profiles can tune malware scanning, but using a non-default profile is not mandatory for basic threat detection.

Option B: SSE already includes built-in anti-malware and sandboxing; it doesn’t require a separate third-party antivirus integration for core features.

Option C: Connectors in SSE are used mainly to reach private applications (ZTNA), not to “reach remote users” for general web browsing.

Therefore, an essential part of enabling threat detection for web browsing is creating an external web profile that enables SSL inspection ? Option D.

HPE Aruba Networking ClearPass Device Insight (CPDI) can show detailed information about a device's communication patterns, including how many destinations the device is accessing. CPDI provides comprehensive visibility into the behavior and activity of devices on the network, allowing the security team to track and analyze communication patterns at a glance. This information is critical for identifying anomalies and potential security threats.

Comprehensive Detailed Explanation

Virtual Network Based Tunneling (VNBT) is the appropriate technology for this use case because:

Traffic Steering: VNBT enables traffic from specific clients or devices to be tunneled through a predefined network path. This allows traffic to pass through intermediate devices such as third-party security appliances.

Policy Enforcement: VNBT can be configured to route traffic based on roles, VLANs, or other policy definitions, ensuring that only specified traffic flows are redirected to the security appliance.

Scalability: This approach simplifies the redirection of traffic without requiring complex physical rewiring or changes to the underlying network topology.

Other Options:

MC-LAG: Primarily used for high-availability and redundancy in multi-chassis link aggregation scenarios, not for traffic redirection through appliances.

Network Analytics Engine (NAE): Used for monitoring and analytics, not traffic steering or forwarding.

Device Profiles: Helps automate switch port configurations for specific device types but does not handle traffic redirection.

1. Understanding the Role Mapping Evaluation:

Role mapping is set to "Evaluate: Select first," meaning the first rule that matches the client attributes will determine the role(s) assigned.

Contractors group: Since the client is in the Contractors group (not Managers), Rule 1 in the Role Mapping Policy does not match.

TEAP-Method-1-Status EQUALS Success: This condition matches Rule 2, so the client is assigned the domain-comp role.

No other rules match, so the default role [Other] is not applied.

2. Resulting Role from Role Mapping Policy:

The client is assigned the domain-comp role.

3. Enforcement Policy Evaluation:

Enforcement policy is also set to "Evaluate: Select first," so the first matching rule determines the enforcement profile.

Rule 1 (Tips Role = manager AND domain-comp):

The client only has the domain-comp role, not manager, so this rule does not match.

Rule 2 (Tips Role = manager):

The client does not have the manager role, so this rule does not match.

Rule 3 (Tips Role = domain-comp):

This rule matches the client's role, but it is not evaluated because the enforcement policy already skipped to the default action after failing the first two rules.

4. Default Enforcement Profile:

Since no rule explicitly matches and the policy evaluation stops at the default, the default profile [Deny Access Profile] is applied.

Final Outcome:

The client is denied access because none of the matching rules satisfy the conditions.

Internet Key Exchange (IKE)/IKEv2 plays a crucial role in an HPE Aruba Networking client-to-site VPN by helping to negotiate the IPsec Security Association (SA) automatically and securely. IKE/IKEv2 handles the authentication and key exchange processes, ensuring that both the client and the VPN gateway can establish a secure IPsec tunnel.

1.SA Negotiation: IKE/IKEv2 automates the negotiation of the Security Association, which defines the parameters for the secure IPsec tunnel.

2.Secure Authentication: It provides a secure method for authenticating the communicating parties and exchanging cryptographic keys.

3.Efficiency: Using IKE/IKEv2 simplifies the setup and maintenance of secure VPN connections, enhancing the overall security and reliability of the VPN.

For a company that wants to apply a standard configuration to all AOS-CX switch ports and dynamically adjust their configuration based on the identity of the user or device that connects, the best approach is to have the switches download user-roles from HPE Aruba Networking ClearPass Policy Manager (CPPM). This method centralizes the configuration of identity-based settings in CPPM, allowing it to dynamically assign roles and policies to switch ports based on authentication and authorization results. This ensures consistent and secure network access control tailored to each user or device.

The Network Analytics Engine (NAE) in AOS-CX switches provides intelligent monitoring, troubleshooting, and performance analysis through predefined or custom scripts. Here’s an analysis of the guidelines for NAE:

A. Each switch model has a maximum number of supported monitors, and one agent might have multiple monitors.

Correct:

Each AOS-CX switch model has hardware and software limitations, including the number of agents and monitors it supports.

Monitors are data collection points for tracking specific metrics like interface statistics, CPU usage, or custom-defined parameters.

Agents are scripts that use monitors to evaluate data, trigger actions, or generate alerts.

Since one agent can have multiple monitors, the total number of monitors might impact the scalability of agents.

B. You can install multiple scripts on a switch, but you can deploy only one agent per script.

Incorrect:

Multiple agents can be deployed from the same script if they monitor different parameters or have different configurations.

The limitation is usually related to the total number of agents and monitors supported by the switch model, not the script itself.

C. The switch will permit you to deploy as many NAE agents as you want, but they might degrade the switch functionality.

Incorrect:

AOS-CX enforces hardware and software limits on the number of agents and monitors. These limits are designed to prevent degradation of switch performance.

You cannot deploy an unlimited number of agents, as the system enforces these restrictions.

D. When you use custom scripts, you can create as many agents from each script as you want.

Incorrect:

While you can use custom scripts to create agents, the total number of agents is subject to the switch's maximum supported limits.

The scalability of agents is still bound by hardware and software constraints, even with custom scripts.

When HPE Aruba Networking Central detects an Infrastructure Attack, such as "Detect adhoc using Valid SSID," the next step is to locate the general area of the threat. You can use HPE Aruba Networking Central floorplans or the identities of the detecting APs to pinpoint the approximate location of the adhoc network. This allows you to physically investigate and address the source of the threat, ensuring that unauthorized or rogue networks are quickly identified and mitigated.

When using HPE Aruba Networking ClearPass Device Insight (CPDI) and you need to reclassify a device to a custom type and apply this classification to all devices with similar attributes, both already discovered and newly discovered, you should follow these steps:

1.Navigate to the device details in CPDI.

2.Select the option to reclassify the device.

3.Create a user rule based on the desired attributes of the device.

4.Choose the "Save & Reclassify" option.

This process ensures that the device is reclassified according to the new custom type and that the rule is applied to all existing and future devices with matching attributes, maintaining consistent classification across the network.

Comprehensive Detailed Explanation

A non-default device posture is applied in scenarios where specific checks on a device's compliance or security state (posture) are required to grant or deny access. The correct answer is:

B. Checking whether a client has antivirus software as a condition for receiving access to resources.

This use case explicitly requires device posture assessment, which involves evaluating the device for attributes like antivirus software, patch levels, or other compliance criteria.

Non-default device posture rules are configured to assess these conditions and enforce the appropriate policy based on the device's state.

Other Options:

A. Applying threat inspection: Threat inspection rules operate independently of device posture and apply based on traffic content, not device compliance.

C. Redirecting compromised clients: This action is typically triggered based on a security event or threat detection, not directly related to device posture evaluation.

D. Integrating with ClearPass OnGuard: While OnGuard can contribute to posture assessment, it does not require a non-default device posture in the SSE rule directly.

Integrating HPE Aruba Networking ClearPass Policy Manager (CPPM) and HPE Aruba Networking ClearPass Device Insight (CPDI) can help a company implement Zero Trust Security by allowing CPDI to use tags to inform CPPM that clients are using prohibited applications. CPPM can then take action, such as telling the network infrastructure to quarantine those clients, ensuring that only compliant and trusted devices have network access.

1.Device Insight Tags: CPDI can monitor client behavior and tag devices that are using prohibited applications.

2.Policy Enforcement: CPPM can use these tags to apply specific enforcement actions, such as quarantining non-compliant devices.

3.Zero Trust Implementation: This integration supports Zero Trust Security by ensuring that all devices are continuously monitored and controlled based on their behavior and compliance with security policies.

To determine the VLAN settings for the "APs" role on AOS-CX switches, it is crucial to know whether the APs bridge or tunnel traffic on their SSIDs. If the APs are bridging traffic, the VLAN settings on the switch need to align with the VLANs used by the SSIDs. If the APs are tunneling traffic to a controller or gateway, the VLAN settings might differ as the traffic is encapsulated and forwarded through the tunnel. Understanding this aspect ensures that the VLAN configuration on the switches correctly supports the traffic forwarding method employed by the APs.

HPE Aruba Networking ZTNA (delivered as part of Aruba SSE) replaces traditional network-level VPN access with application-level access. Key security advantages highlighted in Aruba ZTNA/SSE collateral include:

Applications are no longer exposed directly to the internet; instead, they are fronted by the ZTNA service.

Inbound connectivity to private apps is outbound-only via connectors, eliminating open listening ports and shrinking the external attack surface. www6.h3c.com

Users are granted access only to specific applications, not entire subnets, thereby limiting lateral movement and the blast radius of a compromise.

Aruba documentation explicitly notes that ZTNA “reduces the overall attack surface” and avoids the broad network exposure inherent in classic client-to-site VPNs.

Thus, the most accurate advantage is: ZTNA shrinks the attack surface, eliminating publicly exposed ports and reducing the extent of the private network exposed to remote users ? Option D.

An HPE Aruba Networking AP's Device (TPM) certificate is signed by an HPE Aruba Networking Certificate Authority (CA) and is trusted by many HPE Aruba Networking solutions. This certificate is used for secure communications and device authentication within the Aruba network ecosystem.

1.CA-Signed Certificate: The Device (TPM) certificate is signed by a trusted Aruba CA, ensuring its authenticity and integrity.

2.Trust Across Solutions: Because it is signed by an Aruba CA, it is recognized and trusted by various Aruba solutions, facilitating secure interactions and communications.

3.Security: Using a CA-signed certificate enhances the security of the network by preventing unauthorized access and ensuring that communications are secure.

On Aruba Mobility Controllers, dataplane captures can include wireless frames encapsulated inside GRE (for example, ERM / remote mirroring or tunneled 802.11 data). If Wireshark does not have GRE dissection enabled, these packets may appear as generic IP/UDP payloads, and the inner traffic (client frames) will not decode correctly.

MC dataplane is exactly where GRE-encapsulated user traffic is likely to appear. Enabling GRE in Wireshark allows you to see and decode the inner payload (802.11/Ethernet/IP).

MC control plane traffic is generally not GRE encapsulated data traffic.

For gateways, captures exported as ERM over UDP often require different decoding (e.g., ARUBA_ERM, not generic GRE).

Thus, the most appropriate case to ensure GRE is enabled is when the capture came from the MC dataplane ? Option D.

Traffic Forwarding for APs:

In AOS-10, AP traffic forwarding can happen locally (bridged) or through tunnels to a gateway.

The VLAN settings on the "APs" role depend on whether the APs bridge the SSID traffic locally or forward it through a tunnel.

Option B: Correct. You need to know whether the traffic is bridged or tunneled to determine the VLAN assignments.

Option A: Incorrect. LURs/DURs affect role assignment but not VLAN settings for traffic forwarding.

Option C: Incorrect. Establishing tunnels with gateways is relevant to centralized traffic forwarding, not VLANs for bridged traffic.

Option D: Incorrect. AP IP addressing (static or DHCP) does not impact the VLAN for forwarded SSID traffic.

Packet Capture in Aruba Central:

Aruba Central provides tools for remote packet captures directly from the APs.

On the "Security" page for the AP, you can initiate a packet capture session, specifying the client device and capture duration.

The traffic is captured into a PCAP file, which can be downloaded and analyzed using tools like Wireshark.

Option Analysis:

Option A: Incorrect. While possible via CLI, Aruba Central provides a simpler method for packet captures.

Option B: Correct. Aruba Central’s "Security" page allows you to capture and export client traffic efficiently.

Option C: Incorrect. The "Live Events" page focuses on monitoring events, not packet captures.

Option D: Incorrect. Port mirroring on the switch captures AP traffic but requires more manual configuration and does not isolate client-specific wireless traffic easily.
