HP Aruba Data Center Network Specialist HPE2-W09 Exam Questions

Answer : A

The ArubaOS-CX time-series database helps to support network analytics and troubleshooting is a correct description of the ArubaOS-CX architecture. The time-series database (TSDB) is a component of the ArubaOS-CX software that stores information about the switch's configuration, status, and performance over time.The TSDB helps to support network analytics and troubleshooting by providing historical data and trend analysis for various metrics1.

Answer : A

A GRE tunnel interface is a virtual interface that can encapsulate different network layer protocols inside point-to-point or point-to-multipoint links over an IP network1. It can be assigned an IP address and attached to a VRF.A VRF allows multiple instances of a routing table to co-exist within the same router2.By attaching a GRE tunnel interface to a VRF, you can isolate the traffic of that tunnel from other tunnels and routing domains2.

Answer : B

Attach VNIs 5010 and 5020 to interface 1/1/3 on Switch-2 is not part of a valid configuration to meet the requirements for providing VXLAN services for several VMs and servers using ArubaOS-CX switches. VNIs are virtual network identifiers that are used to identify VXLAN segments.A VNI can only be attached to a VLAN interface, not a physical interface, on an ArubaOS-CX switch1.

Answer : B

A physical interface using Layer 2 mode cannot be attached to a VRF on an ArubaOS-CX switch. A VRF is a virtual routing and forwarding instance that provides logical separation of routing tables on a switch.A physical interface can only be attached to a VRF if it is using Layer 3 mode and has an IP address assigned to it1.

Answer : A

The wait to restore timer (WTR) Is set in units of minutes; you can set it to prevent frequent topology changes due to a link going up and down is a guideline for configuring timers for Ethernet Ring Protection Switching (ERPS) on an ArubaOS-CX switch.The WTR timer is set in units of minutes, and it defines how long a node must wait before restoring traffic on a previously failed link that has recovered1.

Answer : A

Connecting multiple data centers at Layer 2 while minimizing the number of dark fiber connections required is a use case for deploying Ethernet Ring Protection Switching (ERPS). ERPS is a feature that provides loop prevention and fast convergence for Layer 2 networks that use ring topologies.ERPS can be used to connect multiple data centers at Layer 2 using fewer fiber connections than traditional mesh topologies1.

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.
