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.

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.

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.
