HP HP Certifications HPE2-W09 Questions & Answers

• Question 21:

  Refer to the exhibits.

  

  Is this how the switch-1 handles the traffic?

  Solution: A broadcast arrives in VLAN 10 on Switch-1. Switch 1 forwards the frame on all interfaces assigned to VLAN10. except the incoming interface. It replicates the broadcast, encapsulates each broadcast with VXLAN. and sends the VXLAN traffic to 192.168.1.2 and 192.168.1.3.

  A. Yes

  B. No

  Correct Answer: A

  A broadcast arrives in VLAN 10 on Switch-1. Switch 1 forwards the frame on all interfaces assigned to VLAN10, except the incoming interface. It replicates the broadcast, encapsulates each broadcast with VXLAN, and sends the VXLAN traffic to 192.168.1.2 and 192.168.1.3 is 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. Switch-1 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.

• Question 22:

  Is this a way that a data center technology can help meet requirements for multi-tenancy?

  Solution: Virtual Routing and Forwarding (VRF) enables multiple isolated Layer 3 domains, each with its own routing table, to share a physical network.

  A. Yes

  B. No

  Correct Answer: A

  Multi-tenancy is the ability to provide network services to multiple independent customers or tenants on a shared physical infrastructure. One of the challenges of multi-tenancy is to ensure isolation and security between different tenants, while also providing scalability and efficiency. Virtual Routing and Forwarding (VRF) is a data center technology that can help meet these requirements by enabling multiple isolated Layer 3 domains, each with its own routing table, to share a physical network1. VRF allows different tenants to use overlapping IP addresses and routing protocols without interfering with each other. Therefore, this is a valid way that a data center technology can help meet requirements for multi-tenancy.

• Question 23:

  Does this correctly describe routing information advertised by a VXLAN Tunnel Endpoint (VTEP) that uses EVPN?

  Solution: IMET routes advertise the MAC addresses that the VTEP has learned locally in a VXLAN.

  A. Yes

  B. No

  Correct Answer: B

  IMET routes advertise the MAC addresses that the VTEP has learned locally in a VXLAN is not a correct description of routing information advertised by a VXLAN Tunnel Endpoint (VTEP) that uses EVPN. IMET routes are one of the types of routes that EVPN uses to advertise multicast information for VXLAN networks. IMET routes advertise the IP addresses of VTEPs that can join multicast groups for VXLAN segments2.

• Question 24:

  You need to integrate Aruba Fabric Composer (AFC) with customer datacenter software. Is this integration possible?

  Solution: Aruba Fabric Composer (AFC) with Nutanix Hypervisor (AHV)

  A. Yes

  B. No

  Correct Answer: A

  Aruba Fabric Composer (AFC) with Nutanix Hypervisor (AHV) integration is possible. 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 APIs1.

• Question 25:

  Refer to the exhibit.

  

  You need to set up an ArubaOS-CX switch to implement Virtual Extensible LAN (VXLAN) WITHOUT Ethernet VPN (EVPN). The exhibit Indicates which servers should be part of the same VXLANs and the desired VNls for the VXLANs. Assume that the network is already configured to permit each ArubaOS-CX switch to reach each other switch's loopback interface.

  Is this part of the process for setting up VXLAN to meet the requirements?

  Solution: On Switch-1, add VNIs 5010 and 5020 to the same VXLAN interface.

  A. Yes

  B. No

  Correct Answer: B

  VXLAN is a feature of ArubaOS-CX that provides layer 2 connectivity between networks across an IP network1. VXLAN uses a 24-bit identifier called VXLAN Network Identifier (VNI) to segment the layer 2 domain1. VXLAN also uses a tunnel endpoint (VTEP) to encapsulate and decapsulate VXLAN packets1. A VXLAN interface is a logical interface that represents a VNI and is associated with a source IP address and a VRF1. To set up VXLAN without EVPN, you need to create VXLAN interfaces on each switch and configure static VTEP peers1. Based on the exhibit, Switch-1 needs to create two VXLAN interfaces, one with ID 5010 and one with ID 5020, to match the VNIs of the servers connected to it. However, you cannot add multiple VNIs to the same VXLAN interface1. Each VNI must have its own VXLAN interface with a unique source IP address and VRF1. Therefore, this is not part of the process for setting up VXLAN to meet the requirements, and the correct answer is no. For more information on VXLAN and EVPN, refer to the Aruba Data Center Network Specialist (ADCNS) certification datasheet2 and the EVPN VXLAN Guide for your switch model1.

• Question 26:

  You are using NetEdit to manage AruDaOS-CX switches. You want to deploy a standard config to the switches, but need the config to include a few device-specific settings such as hostname and IP address.

  Is this what you should do?

  Solution: Inside a configuration plan, right-click any device-specific parameters and modify the parameter per-device.

  A. Yes

  B. No

  Correct Answer: A

  Inside a configuration plan, right-click any device-specific parameters and modify the parameter per-device is what you should do if you want to use NetEdit to manage ArubaOS-CX switches and deploy a standard config to the switches, but need the config to include a few device-specific settings such as hostname and IP address. This approach allows you to edit any parameter value for individual devices within a configuration plan without affecting other devices or creating separate plans1.

• Question 27:

  You are using NetEdit to manage AruDaOS-CX switches. You want to deploy a standard config to the switches, but need the config to include a few device-specific settings such as hostname and IP address. Is this what you should do?

  Solution: Create two configuration plans, one with the standard config and one with the device-specific settings.

  A. Yes

  B. No

  Correct Answer: B

  Creating two configuration plans, one with the standard config and one with the device-specific settings, is not what you should do. NetEdit is a tool that allows you to manage and monitor multiple switches from a single interface1. It also provides a plan feature that lets you create containers to group devices and execute operations on them, such as deploying, committing, or rolling back device configuration or firmware1. However, you do not need to create two configuration plans for your scenario. You can create one configuration plan with the standard config and use variables to define the device-specific settings1. Variables are placeholders that can be replaced with different values for different devices1. This way, you can deploy a standard config with device-specific settings using one configuration plan1.

• Question 28:

  Is this a way that a data center technology can help meet requirements for multi-tenancy?

  Solution: Virtual Extensible LAN (VXLAN) provides millions of IDs to scale for the needs of a multi-tenant environment

  A. Yes

  B. No

  Correct Answer: A

  Virtual Extensible LAN (VXLAN) provides millions of IDs to scale for the needs of a multi-tenant environment is a way that a data center technology can help meet requirements for multi-tenancy. Multi-tenancy is the ability to provide logical separation and isolation of network resources for different tenants or customers on a shared physical infrastructure. VXLAN is a feature that provides Layer 2 extension over Layer

• Question 29:

  You are configuring Ethernet Ring Protection Switching (ERPS) on an ArubaOS-CX switch. Is this a guideline for configuring timers?

  Solution: The hold off timer causes ERPS switches to delay unblocking a failed link after the link is restored. This can be useful to prevent frequent topology changes.

  A. Yes

  B. No

  Correct Answer: A

  ERPS is a feature of ArubaOS-CX that prevents loops at layer 2 on ring networks1. ERPS uses a protocol called Ring Auto Protection Switching (RAPS) to detect link failures and perform fast traffic switchover1. ERPS has two timers that control the protection switching mechanism: guard timer and hold off timer1. The guard timer prevents false switching caused by delayed or lost RAPS PDUs1. The hold off timer causes ERPS switches to delay unblocking a failed link after the link is restored1. This can be useful to prevent frequent topology changes due to link flapping or network instability1. Therefore, this is a guideline for configuring timers for ERPS, and the correct answer is yes. For more information on ERPS and timers, refer to the Aruba Data Center Network Specialist (ADCNS) certification datasheet2 and the ERPS Guide for your switch model1.

• Question 30:

  Refer to the exhibit.

  

  Switch-1 and Switch-2 ate ArubaOS-CX switches that implement VXLAN WITHOUT Ethernet VPN (EVPN). Switch-2 uses the same VNI-to-VLAN mappings as Switch-1. Is this how the specified servers communicate? Solution: The first time that Server I communicates with Server 3, It sends an ARP request to resolve Server 3's MAC address.

  A. Yes

  B. No

  Correct Answer: B

  The solution is incorrect because Switch-1 and Switch-2 implement VXLAN without EVPN, which means they do not have a control plane to exchange MAC addresses. Therefore, the first time that Server 1 communicates with Server 3, it sends an ARP request to resolve Server 3's IP address, not MAC address. The ARP request is encapsulated in a VXLAN header and sent to the VTEP of Switch-2, which decapsulates it and forwards it to Server 3.
