Aruba Data Center Network Specialist Exam: HPE2-W09

Correct Answer: B

Different virtual MAC must be used for IPv4 and IPv6 Active Gateway is not a true statement about EVPN and IPv6 for configuring an EVPN solution for a dual-stack IPv4 and IPv6 protocol in the overlay networks. Active Gateway is a feature that provides first-hop redundancy for hosts connected to VTEPs using anycast gateway addresses. Active Gateway can use the same virtual MAC address for both IPv4 and IPv6 protocols on the same VNI2.

Correct Answer: B

To help the switch to look inside tunneled traffic and apply different quality of service (QoS) settings to different types of traffic is not a use case for implementing Enhanced Transmission Selection (ETS) on an ArubaOS-CX switch. ETS is a feature that provides bandwidth allocation and priority assignment for different traffic classes based on IEEE 802.1Qaz standard. ETS does not help the switch to look inside tunneled traffic, but rather relies on the priority values in the outer header of the tunneled traffic to apply QoS settings. A better way to help the switch to look inside tunneled traffic and apply different QoS settings to different types of traffic would be to use deep packet inspection (DPI) or application visibility and control (AVC) features.

Correct Answer: A

The show dcbx interface command shows the current DCBx status and the configuration of PFC, ETS, and application priority applied on the interface and the status of the TLVs received from the peer1. The Application Priority Map section

shows the protocol, port/type and priority for both local and remote advertisements. Therefore, this is where you can see whether the connected converged network adapter (CNA) has accepted the application priorities advertised with DCBX.
