HP HP Certifications HPE2-W09 Questions & Answers

• Question 81:

  You need to integrate Aruba Fabric Composer (AFC) with customer datacenter software. Is this integration possible? Solution: Aruba Fabric Composer (AFC) with HPE StoreServ Management Console (SSMC)

  A. Yes

  B. No

  Correct Answer: A

  Aruba Fabric Composer (AFC) with HPE StoreServ Management Console (SSMC) integration is possible. AFC is a software-defined networking solution that simplifies the management and orchestration of data center networks1. It can integrate with various data center software, such as VMware, Ansible, and Kubernetes1. SSMC is a web- based management tool that provides a unified interface for managing HPE 3PAR StoreServ storage systems2. AFC can integrate with SSMC to discover and visualize the storage network infrastructure and provide end-to-end visibility and troubleshooting1. https://www.arubanetworks.com/products/switches/core-and-data-center/fabric-composer/

• Question 82:

  The architect designs a spine and leaf network for a single data center that will use multiple leaf switches as Virtual Tunnel End Points (VTEP). The architect needs to select the type of Integrated Routing and Bridging (IRB) for the solution.

  Is this statement about the IRB type true?

  Solution: Asymmetric IRB requires a third L3 VNI to route packets between ingress and egress VTEPs.

  A. Yes

  B. No

  Correct Answer: A

  Asymmetric IRB requires a third L3 VNI to route packets between ingress and egress VTEPs is a true statement about the IRB type for a spine and leaf network for a single data center that will use multiple leaf switches as Virtual Tunnel End Points (VTEP). Asymmetric IRB is a method of routing traffic between different VXLAN segments using a centralized gateway. In this method, ingress VTEPs route the traffic to the gateway VTEP using a Layer 3 VNI, and egress VTEPs route the traffic to the destination networks using a Layer 2 VNI1. The Layer 3 VNI acts as a transit VNI for inter-VXLAN routing.

• Question 83:

  Is this a best practice when positioning ArubaOS-CX switches in data center networks? Solution: Deploy Aruba CX 6300 switches as data center spine switches.

  A. Yes

  B. No

  Correct Answer: B

  Deploy Aruba CX 6300 switches as data center spine switches is not a best practice when positioning ArubaOS-CX switches in data center networks. The Aruba CX 6300 switches are designed for data center leaf roles, and they provide high density, low latency, and advanced features such as VSX and EVPN. The Aruba CX 83xx switches are more suitable for data center spine roles, and they provide high performance, scalability, and resiliency1.

• Question 84:

  AtubaOS-CX switches are acting as Virtual Extensible LAN (VXLAN) Tunnel Endpoints (VTEPs) WITHOUT Ethernet VPN (EVPN).

  Does this correctly describe how the VTEPs handle VXLAN traffic forwarding?

  Solution: VTEPs that use headend replication forward broadcasts as unicast packets to each VTEP in the same VNI.

  A. Yes

  B. No

  Correct Answer: A

  Headend replication is a method of handling BUM traffic in VXLAN networks without EVPN, where the ingress VTEP replicates every BUM packet and sends them as a separate unicast to the remote egress VTEPs in the same VNI1. This avoids the need for multicast routing in the underlay network, but it can increase the load on the ingress VTEP. Therefore, this correctly describes how the VTEPs handle VXLAN traffic forwarding without EVPN.

• Question 85:

  The architect designs a spine and leaf network for a single data center that will use multiple leaf switches as Virtual Tunnel End Points (VTEP). The architect needs to select the type of Integrated Routing and Bridging (IRB) for the solution.

  Is this statement about the IRB type true?

  Solution: Asymmetric IRB routes packets in the ingress VTEP and then routes packets in the egress VTEP.

  A. Yes

  B. No

  Correct Answer: B

  Asymmetric IRB routes packets in the ingress VTEP and then bridges packets in the egress VTEP1. This means that the ingress VTEP performs both Layer 2 and Layer 3 lookups, while the egress VTEP performs only Layer 2 lookup1. The statement is false because it confuses routing with bridging in the egress VTEP.

• Question 86:

  You enter this command on an ArubaOS-CX switch:

  Switch# show erps status ring 1

  Is this what the specified status means?

  Solution: The status is Pending, which means that the ring is configured but not enabled administratively

  A. Yes

  B. No

  Correct Answer: B

  The status is Pending, which means that the ring is configured but not operational. The ring instance may be in one of the following states: Idle, Initializing, Pending, or Failed1. The Pending state indicates that the ring instance 1s waiting for a trigger event to become operational, such as a link failure or a manual command1. The status does not depend on whether the ring is enabled administratively or not. https://www.arubanetworks.com/techdocs/AOS-CX/10.08/HTML/high_availability/Content/Chp_ERPS/ERPS_cmds/sho-erp-sta4.htm

• Question 87:

  Is this part of the process for using NetEdit to update firmware on ArubaOS-CX switches? Solution: Create a conformance test to check that the firmware matches the desired version.

  A. Yes

  B. No

  Correct Answer: A

  Creating a conformance test to check that the firmware matches the desired version is part of the process for using NetEdit to update firmware on ArubaOS-CX switches1. NetEdit is a tool that allows you to manage and monitor multiple switches from a single interface1. It also provides a conformance feature that lets you create tests to verify that the switches comply with your desired configuration and firmware settings1. You can use NetEdit to create a conformance test to check that the firmware matches the desired version and then run it on the switches1. https://asp.arubanetworks.com/downloads;products=Aruba%20Switches

• Question 88:

  Is this a use case for implementing Enhanced Transmission Selection (ETS) on an ArubaOS-CX switch? Solution: ensures a minimum bandwidth guarantee between two endpoints traffic with various 802.1 p values.

  A. Yes

  B. No

  Correct Answer: A

  To ensure a minimum bandwidth guarantee between two endpoints traffic with various 802.1p values is 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 can help to ensure a minimum bandwidth guarantee between two endpoints by assigning different priority groups and bandwidth percentages to different traffic classes based on their 802.1p values1.

• Question 89:

  Your task is to configure an EVPN solution for a dual-stack IPv4 and IPv6 protocol in the overlay networks. Is this statement about EVPN and IPv6 correct? Solution: The IPv6 and IPv4 overlay networks can be encapsulated with VXLAN and transmitted through the underlay network.

  A. Yes

  B. No

  Correct Answer: A

  The IPv6 and IPv4 overlay networks can be encapsulated with VXLAN and transmitted through the underlay network is a true statement about EVPN and IPv6 for configuring an EVPN solution for a dual-stack IPv4 and IPv6 protocol in the overlay networks. VXLAN is a feature that provides Layer 2 extension over Layer 3 networks using UDP encapsulation. VXLAN can support both IPv4 and IPv6 overlay networks over an IPv4 or IPv6 underlay network2.

• Question 90:

  The architect designs a spine and leaf network for a single data center that will use multiple leaf switches as Virtual Tunnel End Points (VTEP). The architect needs to select the type of Integrated Routing and Bridging (IRB) for the solution.

  Is this statement about the IRB type true?

  Solution: In the Asymmetric IRB egress VTEPs bridge the traffic to the destination networks.

  A. Yes

  B. No

  Correct Answer: B

  In the Asymmetric IRB egress VTEPs bridge the traffic to the destination networks is not a true statement about the IRB type for a spine and leaf network for a single data center that will use multiple leaf switches as Virtual Tunnel End Points (VTEP). Asymmetric IRB is a method of routing traffic between different VXLAN segments using a centralized gateway. In this method, ingress VTEPs route the traffic to the gateway VTEP using a Layer 3 VNI, and egress VTEPs route the traffic to the destination networks using a Layer 2 VNI1.
