AAA stands for Authentication, Authorization, and Accounting. It is a framework that provides security to network resources by controlling who can access them (authentication), what they can do (authorization), and what actions they perform (accounting). AAA can be implemented by using the local database of the device or by using an external server such as Cisco ISE (Identity Services Engine).

The question asks which configuration item makes it possible to have the AAA session on the network. A session is a logical connection between a user and a network device. A session can be initiated by various methods, such as console, telnet, SSH, PPP, etc. Each session can have different AAA policies applied to it, depending on the method list configured for that session.

A method list is a set of rules that define the authentication, authorization, and accounting methods to be used for a particular session. A method list can be named or default. A named method list is applied to a specific session by using the login, authorization, or accounting keyword followed by the name of the method list. A default method list is applied to all sessions that do not have a named method list configured.

The configuration item that makes it possible to have the AAA session on the network is the aaa authorization network default group ise command. This command configures a default method list for network authorization, which is the process of determining the network services and attributes that a user is allowed to access after authentication. The command specifies that the network authorization method is group, which means that the device will use an external server (such as Cisco ISE) to obtain the authorization information for the user. The command also specifies that the name of the server group is ise, which means that the device will use the server group defined by the aaa group server radius ise command.

The other options are incorrect because they do not configure a default method list for network authorization. Option A configures a named method list for login authentication, which is the process of verifying the identity of the user. Option B configures a default method list for enable authentication, which is the process of verifying the identity of the user who wants to enter the privileged EXEC mode. Option D configures a default method list for exec authorization, which is the process of determining the commands and features that a user can access in the EXEC mode. References:

 Cisco Umbrella evaluates policies from the top down and looks for a matching identity and destination. Once a match is found, Umbrella applies that policy’s settings to the identity and destination and stops evaluating all other DNS policies. Therefore, to ensure that the policy that the identity must use takes precedence over the second one, the engineer should make the correct policy first in the policy order. This way, Umbrella will match the identity to the correct policy before checking the second policy. The other options are not correct because they do not guarantee that the identity will use the correct policy. Configuring the default policy to redirect the requests to the correct policy will not work if the identity matches another policy before the default one. Placing the policy with the most-specific configuration last in the policy order will not work if the identity matches a less-specific policy before the last one. Configuring only the policy with the most recently changed timestamp will not work if the identity matches an older policy before the newer one. References :=

Talos Intelligence is a comprehensive threat intelligence service that provides up-to-date information on URL filtering, reputations, and vulnerability information. Talos Intelligence can be integrated with Cisco FTD and Cisco WSA to enhance the security and visibility of the network. Cisco FTD and Cisco WSA can leverage the Talos Intelligence feeds to perform Security Intelligence filtering, which allows the devices to block or allow traffic based on the reputation of the source or destination IP addresses, URLs, or DNS requests. Talos Intelligence feeds are updated regularly and can be configured to download automatically or manually on the FTD and WSA devices12345. References := 1: Cisco Talos Intelligence Group - Comprehensive Threat Intelligence 2: Threat Intelligence on Cisco Stealthwatch - Cisco Community 3: Third-Party Integration of Security Feeds with FMC (Cisco Threat … - Cisco Community 4: Cisco Firepower Threat Defense Configuration Guide for Firepower Device … 5: Cisco Firepower Threat Defense Configuration Guide for Firepower Device …

The cloud security shared responsibility model is a way of describing how the security tasks and obligations are divided between the cloud service provider (CSP) and the customer, depending on the type of cloud service model used. The cloud service models are:

• Software as a Service (SaaS): The CSP provides and manages the entire software stack, including the applications, data, runtime, middleware, operating system, virtualization, servers, storage, and networking. The customer only needs to access the software through a web browser or an application. The customer is responsible for managing their own data and identities, as well as configuring the security settings of the software. The CSP is responsible for everything else, including patching the operating system and the applications12
• Platform as a Service (PaaS): The CSP provides and manages the platform layer, including the runtime, middleware, operating system, virtualization, servers, storage, and networking. The customer can deploy and run their own applications and data on the platform, using the tools and languages supported by the CSP. The customer is responsible for managing their own applications and data, as well as configuring the security settings of the platform. The CSP is responsible for patching the operating system and the middleware12
• Infrastructure as a Service (IaaS): The CSP provides and manages the infrastructure layer, including the virtualization, servers, storage, and networking. The customer can provision and use virtual machines, containers, or bare metal servers, and install their own operating system, middleware, applications, and data. The customer is responsible for managing and patching their own operating system, middleware, applications, and data, as well as configuring the security settings of the infrastructure. The CSP is responsible for the physical security and availability of the infrastructure12

Southbound APIs are used to communicate between the SDN Controller and the switches and routers of the network. They can be open-source or proprietary. They facilitate control over the network and enable the SDN Controller to dynamically make changes according to real-time demands and needs. OpenFlow and OpFlex are two examples of southbound APIs. OpenFlow, which was developed by the Open Networking Foundation (ONF), is the first and probably most well-known southbound interface. OpenFlow defines the way the SDN Controller should interact with the forwarding plane to make adjustments to the network, so it can better adapt to changing business requirements. With OpenFlow, entries can be added and removed to the internal flow-table of switches and routers to make the network more responsive to real-time traffic demands. OpFlex, which was proposed by Cisco, is another southbound interface that uses a declarative model to communicate policies and state between the controller and the network devices. OpFlex allows the network devices to retain some intelligence and autonomy, while still being managed by the controller. OpFlex is designed to be flexible and extensible, and can support different types of network devices and services. Services running over the network, external application APIs, and applications running over the network are not southbound APIs, as they do not directly communicate between the controller and the network devices. Therefore, the correct answer is B and E. References :=
