HP Aruba Data Center Network Specialist HPE2-W09 Exam Questions

Answer : B

Agents do not collect data every minute and send the data to a centralized SNMP server in SNMP traps.NAE is a feature that provides network operators with distributed analytics for faster troubleshooting and resolution of network-impacting issues1.Agents are scripts that run on ArubaOS-CX switches and collect data from various sources, such as CLI commands, REST APIs, or syslog messages1.Agents can also define conditions and actions based on the collected data1.Agents do not send the data to a centralized SNMP server, but store it locally on the switch1.Agents can also send alerts to external systems, such as email servers or syslog servers, but not in SNMP traps1. The statement is false because it incorrectly describes how NAE agents work.

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 : A

To reduce the amount of traffic sent over the ISL between Switch-1 and Switch-2, enable active forwarding on LAG 100 on both Switch-1 and Switch-2 is a correct explanation of how to control how core-to-access traffic is forwarded. Switch-1, Switch-2, and the router run OSPF on LAG 100, which is a Layer 3 LAG. Active forwarding is a feature that allows a switch to select one link as active and one link as standby for each direction of traffic in a LAG.Enabling active forwarding on LAG 100 on both Switch-1 and Switch-2 would reduce the amount of traffic sent over the ISL by sending traffic over only one link instead of both1.

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.

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.

Answer : A

Agents write data to the switch's current state database is a correct description of how Network Analytics Engine (NAE) agents work. NAE agents are scripts that run on ArubaOS-CX switches and collect data from various sources such as CLI commands, REST APIs, SNMP queries, etc.The agents write the collected data to the switch's current state database (CSDB), which stores information about the switch's configuration, status, and performance1.

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.
