HPE2-W09 Online Practice Questions and Answers

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: A

Automated provisioning of LAGs between AHV and VSX is an operation supported when Aruba Fabric Composer (AFC) is integrated with Nutanix. AFC is a tool that provides automation and orchestration for managing data center networks composed of ArubaOS-CX switches. AFC can integrate with various data center software such as VMware vSphere, Nutanix AHV, Microsoft Hyper-V, etc. AFC can discover, monitor, and configure Nutanix AHV clusters and hosts using REST APIs. AFC can also automate the provisioning of LAGs between AHV and VSX by creating VSX LAGs or MC-LAGs on the ArubaOS-CX switches and configuring the corresponding LAGs on the AHV hosts1.

Correct Answer: A

Combine multiple links between two data centers into link aggregations (but not multi-chassis ones) is part of a valid strategy for load sharing traffic across the links in an Ethernet Ring Protection Switching (ERPS) ring. ERPS is a feature that provides loop prevention and fast convergence for Layer 2 networks that use ring topologies. ERPS can support link aggregation groups (LAGs) between two nodes in a ring as long as they are not multi-chassis LAGs (MC-LAGs). MC-LAGs are not supported by ERPS because they can create loops in the ring topology.

Correct Answer: A

Configuring trust of CoS on the interface is a requirement for implementing Priority Flow Control (PFC) on an ArubaOS-CX switch interface. PFC is a feature that allows a switch to pause traffic on a per-class basis using IEEE 802.1Qbb frames. To use PFC, the switch must trust the CoS values in the incoming frames and map them to priority groups and queues1.

Correct Answer: A

Use a firmware update plan to manage both updating the Image on selected devices and reboot is part of the process for using NetEdit to update firmware on ArubaOS- CX switches. NetEdit is a tool that provides automation and analytics for managing ArubaOS-CX switches. A firmware update plan is a type of plan that allows you to update the firmware image on one or more switches and reboot them as needed1.

Correct Answer: B

A broadcast arrives in VLAN 10 on Switch-1. Switch 1 forwards the frame on all interfaces assigned to VLAN 10, except the incoming interface. It encapsulates the broadcast with VXLAN and sends it to 192.168.1.3, but not 192.168.1.2 is not a correct explanation of how the switch handles the traffic. Switch-1, Switch-2, and Switch-3 are ArubaOS-CX switches that use VXLAN and EVPN to provide Layer 2 extension over Layer 3 networks. VXLAN is a feature that uses UDP encapsulation to tunnel Layer 2 frames over Layer 3 networks using VNIs. EVPN is a feature that uses BGP to advertise multicast information for VXLAN networks using IMET routes. Switch-1 receives a broadcast in VLAN 10, which belongs to VNI 5010. Switch-1 forwards the frame on all interfaces assigned to VLAN 10, except the incoming interface, as per normal Layer 2 switching behavior. However, Switch-1 does not encapsulate the broadcast with VXLAN and send it only to 192.168.1.3, which is Switch-2's loopback interface, but rather replicates the broadcast, encapsulates each broadcast with VXLAN, and sends the VXLAN traffic to both 192.168.1.2 and 192.168.1.3, which are Switch-3's and Switch-2's loopback interfaces respectively.

Correct Answer: B

The Virtual Switching Extension (VSX) is a high availability solution that provides industry-leading performance and simplicity for campus and data center networks

1. VSX does not implement a single control plane for the core fabric, but rather a dual control plane that allows independent software upgrades and configuration changes on each switch2. VSX also provides active-active forwarding and load balancing across both switches, eliminating the need for Spanning Tree Protocol (STP) or other loop prevention mechanisms2. Therefore, this is not a use case for implementing VSX at the core. Reference: https://www.arubanetworks.com/

Correct Answer: A

Creating two ERPS instances for the ring and assigning different VLANs and different RPLs to each instance 1s part of a valid strategy for load sharing traffic across the links in an ERPS solution1. ERPS is a protocol that provides protection and recovery for Ethernet traffic in a ring topology1. It uses a RPL to block one of the links in the ring and prevent loops1. By creating two ERPS instances with different RPLs, you can use both links in the ring for different VLANs and achieve load sharing1.

Correct Answer: A

It collects information about the switch hardware is something that NetEdit 2.0 does after it discovers a switch. NetEdit 2.0 is a tool that provides configuration management and validation for ArubaOS-CX and ArubaOS-Switch devices. NetEdit 2.0 can discover switches using various methods such as IP range scan, LLDP scan, CSV import, etc. After NetEdit 2.0 discovers a switch, it collects information about the switch hardware such as model number, serial number, MAC address, firmware version, etc1.

Correct Answer: B

Adding a route with this command: ip route 10.1.20.0/24 vlan20 vrf A is not part of a valid setup for meeting these requirements. This command would add a static route for 10.1.20.0/24 in VRF A, but it would not be able to reach VLAN 20 on Switch-2 because Switch-2 does not have a VLAN interface for VLAN 20 in VRF A. To make the services in VLAN 30 available to devices in 10.1.20.0/24 in VRF B, you need to use inter- VRF routing or route leaking between VRF A and VRF B on Switch-11.
