HP HPE7-A01 Practice Test 30

Question 290

For an HPE Aruba Networking campus deployment, a switch NAE agent cannot read a protected CLI command after AAA changes. Which action best addresses it?

Compare mirrored packet captures from the configured source and destination ports.
Use supported sFlow telemetry instead of full packet mirroring.
Correct site assignments without assuming the configuration group is a site.
Verify NAE command authorization under the intended AAA policy.

Explanation

Correct Answer

NAE operations may be constrained by command authorization. The engineer should verify NAE command authorization under the intended AAA policy.

Incorrect Answers

Port mirroring supports packet inspection; it cannot resolve NAE command authorization failures following an AAA policy change.

sFlow samples packets and interface counters for flow visibility. It is not a direct remedy for the condition described.

Groups primarily determine configuration; sites support physical/location reporting. It is not a direct remedy for the condition described.

Question 291

A device requires multiple OSPF routes to carry equal-cost flows. Which change most directly meets this campus requirement?

Deploy suitable route reflectors and client relationships.
Configure supported ECMP behavior and equal metrics for eligible paths.
Apply route policy to the correct BGP neighbor and direction.
Enable compatible OSPF participation on the proper L3 interfaces.

Explanation

Correct Answer

Equal-cost eligible next hops can be installed for load distribution. The engineer should configure supported ECMP behavior and equal metrics for eligible paths.

Incorrect Answers

Route reflection reduces the iBGP full-mesh requirement. It is not a direct remedy for the condition described.

Import and export policy have different control-plane effects. It is not a direct remedy for the condition described.

VPN tunnel establishment does not itself form a routing adjacency. It is not a direct remedy for the condition described.

Question 292

The engineer reports completing this change: Enable the supported BPDU protection feature on the edge. Which verification should be included in the handover?

Join and leave a test group and observe forwarding-port membership.
Observe LACP negotiation and the active forwarding members of an unrelated uplink bundle.
Inject a controlled BPDU and review protection event and port state.
Correlate MAC move events with port counters and topology.

Explanation

Correct Answer

BPDU protection can isolate ports that violate the expected edge role. Inject a controlled BPDU and review protection event and port state directly tests the desired behavior.

Incorrect Answers

IGMP snooping limits eligible multicast delivery to interested ports. That observation tests a different condition, not the required result.

LACP verification checks aggregation state, not whether BPDU protection responds to an unexpected bridge on the edge port.

Rapid MAC moves may indicate a loop, duplicated host or roaming bridge. That observation tests a different condition, not the required result.

Question 293

The campus team is closing a service ticket about this condition: A voice deployment must reduce repeated full authentication during roaming. Which validation step is most relevant?

Monitor roam RSSI and handoff delay in the hallway.
Compare candidate AP signal and steering event logs.
Measure coverage overlap and retries across the floor.
Compare authentication exchange duration during controlled roaming.

Explanation

Correct Answer

Fast transition can reduce reassociation authentication overhead. Compare authentication exchange duration during controlled roaming directly tests the desired behavior.

Incorrect Answers

Excess cell reach and very low data rates can promote sticky clients. That observation tests a different condition, not the required result.

Client-steering features encourage better associations but cannot override all client behavior. That observation tests a different condition, not the required result.

Excess transmit power can enlarge contention cells and delay roaming. That observation tests a different condition, not the required result.

Question 294

A network team reports the following condition: Central management becomes unreachable but existing LAN forwarding must continue. Select the most appropriate response.

Validate the supported local forwarding behavior of the deployed solution.
Build a supported VSX pair with matching VSX LAG configuration.
Configure consistent active-gateway IP and virtual MAC on both peers.
Deploy a supported VRRP first-hop redundancy group.

Explanation

Correct Answer

Management-plane loss should be evaluated separately from the user forwarding path. The engineer should validate the supported local forwarding behavior of the deployed solution.

Incorrect Answers

VSX coordinates two switches to provide multi-chassis LAG forwarding. It is not a direct remedy for the condition described.

VSX active gateway provides a shared first-hop identity on appropriate SVIs. It is not a direct remedy for the condition described.

VRRP can provide a shared virtual gateway independent of a VSX pair. It is not a direct remedy for the condition described.

Question 295

An engineer is planning corrective work because a routing adjacency must detect a failed peer faster than hello timers. Which step should be prioritized?

Review ISL/keepalive health and split-brain protection design.
Use supported BFD where it is interoperable with the routing protocol.
Build a supported VSX pair with matching VSX LAG configuration.
Ensure RF coverage overlaps with an appropriate neighbor cell plan.

Explanation

Correct Answer

BFD provides fast liveliness information separate from normal route timers. The engineer should use supported BFD where it is interoperable with the routing protocol.

Incorrect Answers

Peer-state detection and the configured safeguards govern split failure response. It is not a direct remedy for the condition described.

VSX coordinates two switches to provide multi-chassis LAG forwarding. It is not a direct remedy for the condition described.

Redundant coverage is a radio design concern, not only switch redundancy. It is not a direct remedy for the condition described.

Question 296

During campus implementation, some wireless clients fail only after a certificate refresh. What should the engineer configure or correct?

Check DNS resolver assignment and reachability.
Find the exact matching ACE and its direction before broad changes.
Inspect EAP/TLS trust and expiration before changing WLAN channels.
Capture on an appropriate mirrored port and correlate timestamps.

Explanation

Correct Answer

Certificate validation occurs after the client discovers the SSID. The engineer should inspect EAP/TLS trust and expiration before changing WLAN channels.

Incorrect Answers

Name-resolution failure can resemble a general network outage. It is not a direct remedy for the condition described.

ACL ordering and attachment point determine real packet authorization. It is not a direct remedy for the condition described.

Packet capture distinguishes transport retransmissions, resets and filtering. It is not a direct remedy for the condition described.

Question 297

After completing the planned work for this situation—an application is marked EF but packets remain in the best-effort queue—how should success be checked?

Compare channel occupancy and performance at 20/40/80 MHz.
Capture DSCP and inspect queue maps on the bottleneck switch.
Measure multicast loss and radio airtime during stream replication.
Measure BSS transition and user-packet interruption times.

Explanation

Correct Answer

Classification and queue scheduling both matter for end-to-end QoS. Capture DSCP and inspect queue maps on the bottleneck switch directly tests the desired behavior.

Incorrect Answers

Wide channels can reduce the number of independent neighboring cells. That observation tests a different condition, not the required result.

Multicast transmissions can consume disproportionate shared airtime. That observation tests a different condition, not the required result.

Roaming performance depends on scan, authentication and mobility handling. That observation tests a different condition, not the required result.

Question 298

During campus implementation, a switch port intermittently enters a protection-disabled state after a bad patch. What should the engineer configure or correct?

Configure a trunk with the required allowed VLANs.
Set intentional root priorities and protect upstream ports.
Configure an appropriate routed SVI and necessary forwarding policy.
Examine errdisable or protection events before re-enabling.

Explanation

Correct Answer

An automatic protection feature may be intentionally shutting the port. The engineer should examine errdisable or protection events before re-enabling.

Incorrect Answers

An 802.1Q trunk transports multiple logical Ethernet networks. It is not a direct remedy for the condition described.

Spanning-tree root selection must reflect the planned campus topology. It is not a direct remedy for the condition described.

VLAN creation alone provides Layer 2 membership, not inter-VLAN routing. It is not a direct remedy for the condition described.

Question 299

A technician has applied this fix: Inspect EAP/TLS trust and expiration before changing WLAN channels. Which observation would provide the strongest acceptance evidence?

Compare RADIUS/supplicant TLS errors for failing clients.
Inspect the request/response exchange during failure.
Compare DNS lookup with direct IP connectivity.
Trace one permitted and denied test flow against hit counters.

Explanation

Correct Answer

Certificate validation occurs after the client discovers the SSID. Compare RADIUS/supplicant TLS errors for failing clients directly tests the desired behavior.

Incorrect Answers

Packet capture distinguishes transport retransmissions, resets and filtering. That observation tests a different condition, not the required result.

Name-resolution failure can resemble a general network outage. That observation tests a different condition, not the required result.

ACL ordering and attachment point determine real packet authorization. That observation tests a different condition, not the required result.

Question 300

An EAP-TLS server uses a certificate with the wrong name. Which change most directly meets this campus requirement?

Correct server identity/SAN to match client trust expectations.
Use supported RADIUS CoA or reauthorization workflow.
Install the required trust anchor or replace the untrusted certificate.
Ensure endpoint profiling/group mapping is applied consistently.

Explanation

Correct Answer

Supplicants may reject a server even when its signing CA is trusted. The engineer should correct server identity/SAN to match client trust expectations.

Incorrect Answers

Change of Authorization can update session policy without a full reboot. It is not a direct remedy for the condition described.

EAP-TLS succeeds only with a valid trusted certificate chain. It is not a direct remedy for the condition described.

Device category and enforcement mapping must follow endpoint identity across locations. It is not a direct remedy for the condition described.
