HPE Aruba Network Data Center Professional (HPE7-A05) Certification Sample Questions

02. The high-level design calls for distributed routing at every leaf of an EVPN-VXLAN fabric. Each tenant has many subnets but most leaves host only a few of them, and the customer wants to limit the MAC and ARP state that each leaf holds. Which gateway model should the low-level design specify?
a) Asymmetric IRB, with every tenant VNI configured on every leaf
b) Symmetric IRB with a distributed anycast gateway and an L3 VNI per tenant VRF
c) Static VXLAN with flood-and-learn on every leaf
d) Centralized L3 gateways on the border leaves and only Layer 2 on the server leaves

03. A VSX leaf pair reaches the core through an upstream VSX LAG, and servers attach through their own VSX LAGs. After the secondary reboots for maintenance, the routing adjacency over the upstream LAG forms only when the link-up delay ends, so the secondary raises its server LAGs before it has learned any upstream routes.
What should the engineer change before the next reboot?
a) Reboot both peers together during each future maintenance
b) Disable split recovery on the pair before each planned reboot
c) Exclude the upstream LAG from the scope of the link-up delay timer
d) Set a shorter link-up delay timer on the secondary

04. The port map shows each leaf's spine uplinks running to a spine row in another hall over the building's existing single-mode fiber. The BoM lists short-reach multimode transceivers for those uplinks, the same type used for in-rack server connections.
What should BoM validation require?
a) Keep the multimode optics and validate the links with light-level checks during installation
b) Transceivers whose fiber type and reach match the single-mode run to the spine hall
c) Direct attach copper cables for the spine uplinks
d) Higher-speed multimode transceivers, since a faster optic compensates for the longer run

05. An NAE-Lite agent on each leaf raises a syslog alert when CPU utilization crosses a set value. Brief CPU spikes lasting a few seconds trip it many times a day, but the operations team wants an alert only when high CPU persists long enough to threaten service.
Which change to the agent's condition meets this requirement?
a) Make the condition hold for a set duration before it counts as met
b) Raise the trigger value close to the maximum CPU the leaf can reach
c) Add a pause after the condition is met so monitoring stops for a while
d) Set the condition's status to critical so operators can rank each spike

06. Two installers are patching about 100 server and uplink cables for a new leaf pair. The LLD's cabling plan gives each cable an ID and both of its endpoints, and the staged configurations were built from that same port map. Which practice best supports the installation validation that follows?
a) Label only the switch end, since the server end is visible in the server inventory
b) Label both ends with the plan's cable ID and patch to the listed ports
c) Patch the uplinks now and let the server team choose server ports later
d) Patch to any free port and update the cabling plan afterwards from LLDP output

07. A server has been cabled to both switches of a VSX pair, and the implementer has configured the matching VSX LAG and VLANs on both peers. The server team says the host LACP team is configured. Which step confirms that the integration matches the design?
a) Ask the server team to confirm their NIC team is up
b) Ping the server once from the primary switch
c) Check show lacp interfaces multi-chassis and VSX consistency
d) Write the configuration to memory and close the change

08. Staging of a VSX leaf pair is complete: the switches are burned in, run the target release and carry their base configuration. The project manager wants to book the installation window. Which exit check from staging best ensures readiness for deployment?
a) Ship once the switches boot cleanly and leave LLD checks to the configuration phase
b) Book the window first and finish the staging tests on site during the installation
c) Reset the switches to factory defaults before they ship
d) Confirm the staged configs match the LLD and that the site is ready for the window

09. An implementer is writing a script that reads interface data from AOS-CX switches through the REST API and posts the results to the customer's automation platform, which also exposes a REST interface. In which format will the script typically exchange structured data with both APIs?
a) JSON objects in the HTTP request and response bodies
b) XML documents validated against a vendor schema
c) CSV rows with one interface on each line
d) YAML playbooks executed against each switch

10. Switch ports along an NVMe over RoCE path have PFC for the storage priority and ETS shares configured consistently on every hop. A batch of new servers had their NIC DCB settings entered by hand, and those hosts alone show drops and retransmissions under load.
Which change best keeps the hosts aligned with the fabric?
a) Enable PFC on every priority on the server-facing ports
b) Move storage traffic into its own VRF on the servers' links
c) Use DCBX so the hosts accept the switch's DCB settings
d) Raise the MTU on the new servers' storage interfaces
