HP HPE6-A73 Exam Practice Questions (P. 2)

To set up a VLAN specifically for voice on an AOS-CX switch, the correct configuration involves declaring the VLAN and then applying the voice command within its context. For example, you'd start by entering the VLAN configuration mode with 'vlan ', followed by 'voice' to designate it as a voice VLAN. This ensures the switch recognizes and optimally supports voice traffic on that VLAN, providing necessary QoS and prioritization for voice communications. This setup is crucial for maintaining clear and uninterrupted voice services on your network.

The correct implementation for the scenario described is the Active Gateway feature in AOS-CX switches with VSX capabilities. This allows both VSX-capable core switches to handle traffic directed to the default gateway, differing from VRRP which supports an active-standby configuration where only the active switch handles traffic. Active Gateway supports active-active traffic processing, making it more suitable for environments demanding high availability and resiliency. This recommendation aligns with the cited references and best practices in the scenario where an administrator is setting up a campus switching infrastructure.

The accurate description of traffic handling between AOS-CX switches and Aruba Mobility Controllers (MCs) is that the switch employs the Protocols Policy Administrative Interface (PAPI) for the control plane and Generic Routing Encapsulation (GRE) for the data plane. Unlike Access Points, AOS-CX switches do not use IPSec for the PAPI connection protection; instead, they allow optional implementation of an MD5 HMAC function for securing this protocol. This correct understanding refutes the earlier belief that AOS-CX supports only port-based tunneling and aligns with specifics provided in the study materials referencing the official documentation.

IGMP does indeed require both join and leave messages to manage multicast member lists effectively on a network, primarily through what's known as grafting and pruning processes. However, it’s important to correct the potential misconception about IGMP’s functionality. It's True that IGMP itself doesn't directly prune or graft multicast traffic—these actions are typically under the purview of protocols such as Protocol Independent Multicast (PIM). But within the context of IGMP operations on a switch, these terms are often used informally to describe how IGMP helps manage and optimize multicast traffic by maintaining and updating the group membership lists essential for multicast routing efficiency.
