HPE2-W09 Online Practice Questions and Answers

Correct Answer: A

The solution is correct because using the same speed on every link in the ISL is a guideline for establishing a VSX ISL between two ArubaOS-CX switches. Using the same speed on every link in the ISL ensures consistent performance and avoids potential issues with link aggregation. Therefore, using the same speed on every link in the ISL is a good practice for establishing a VSX ISL.

Correct Answer: A

VSX features a dual control plane while VSF features a single control plane. VSX and VSF are both high availability solutions that provide redundancy and load balancing across a pair of switches1. However, VSX features a dual control plane, which means that each switch has its own independent configuration and state information1 . VSF features a single control plane, which means that one switch acts as the commander and synchronizes the configuration and state information to the other switch1. The statement is true because it correctly describes the difference between VSX and VSF control planes.

Correct Answer: B

The status is Idle, which means that the ring is up and fully connected with the RPL port blocked is not what the specified status means for Ethernet Ring Protection Switching (ERPS) on an ArubaOS-CX switch. Idle is one of the possible statuses for an ERPS ring instance, but it indicates that the ring is not operational and no port is blocked. This can happen when the ring is not configured properly or when there is a miscommunication between the nodes1.

Correct Answer: B

A layer 2 VLAN is a single broadcast domain that works on the data link layer

1.

It cannot be assigned an IP address or attached to a VRF. A VRF requires a layer 3 interface that works on the network layer and can perform routing between different VLANs

2.

A layer 2 VLAN can only communicate within itself, not with other VLANs or routing domains1.

Correct Answer: B

The solution is incorrect because adding VRF B as the secondary VRF on VLAN interface 30 is not part of a valid setup for meeting these requirements. Adding VRF B as the secondary VRF on VLAN interface 30 would allow devices in VLAN 30 to communicate with devices in VRF B, but not vice versa. Therefore, adding VRF B as the secondary VRF on VLAN interface 30 is not sufficient for meeting these requirements. https://www.arubanetworks.com/support-services/ training-services/data-center-network- specialist/

Correct Answer: A

Deploying Aruba CX 8400 switches as core switches for very large three-tier data center networks is how you should position switches in the ArubaOS-CX portfolio for data center networks. ArubaOS-CX is an operating system that provides advanced features and automation capabilities for data center networks1. It runs on various switch models that are designed for different roles and scenarios in the data center1. Aruba CX 8400 switches are modular switches that offer high performance, scalability, and reliability for the core layer of very large three-tier data center networks1. The statement is true because it correctly describes how to position Aruba CX 8400 switches in the ArubaOS-CX portfolio for data center networks.

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.

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.

Correct Answer: B

A loopback interface can be attached to a VRF on an ArubaOS-CX switch. A loopback interface is a virtual interface that has an IP address assigned to it and is always up. A loopback interface can be attached to a VRF by using the vrf attach command under its configuration mode1.

Correct Answer: A

The solution is correct because making sure that the SSH server is enabled is a minimum requirement for setting up communications between the switch and NetEdit. NetEdit uses SSH to establish a secure connection to the switch and execute commands on it. Therefore, making sure that the SSH server is enabled is necessary for setting up communications between the switch and NetEdit.
