HPE7-A08 practice question 25 of 35

Which two features in Aruba CX switches help in automating network-wide policy enforcement? (Select two)

Full set: 342 questions
Answer options
A: Network Analytics Engine (NAE)
B: Dynamic Segmentation Correct answer
C: Virtual Switching Framework (VSF)
D: Aruba NetEdit Correct answer
Correct Answer:
B. Dynamic Segmentation; D. Aruba NetEdit
Explanation

Aruba Dynamic Segmentation centralizes and automates policy enforcement by integrating with Aruba ClearPass Policy Manager. This allows for user and device-based policies (roles, ACLs, QoS) to be defined once and then dynamically applied at the switch port as clients connect, regardless of their location. This automates policy enforcement on a per-connection basis. Aruba NetEdit is a network configuration and orchestration tool that automates the deployment of configurations, including security policies like ACLs, across multiple Aruba CX switches. It enables administrators to define, validate, and push consistent policies network-wide from a single interface, thereby automating large-scale policy enforcement and ensuring compliance.

Why Incorrect

A. Network Analytics Engine (NAE) is a framework for monitoring and troubleshooting network health and performance, not for deploying or enforcing network-wide access policies.
C. Virtual Switching Framework (VSF) is a stacking technology that allows multiple physical switches to be managed as a single logical device, simplifying local management but not automating network-wide policy.
