HP HPE7-A01 Practice Test 51

Question 500

The campus team is closing a service ticket about this condition: Large OSPF networks have oversized summary routes at the distribution boundary. Which validation step is most relevant?

Compare advertised prefixes and connected reachability after aggregation.
Inspect route-based tunnel IPs and OSPF neighbor state.
Inject approved and denied test routes and examine propagated LSAs.
Inspect path attributes and selected best path for one prefix.

Explanation

Correct Answer

Summarization reduces route entries and update churn where topology permits. Compare advertised prefixes and connected reachability after aggregation directly tests the desired behavior.

Incorrect Answers

VPN tunnel establishment does not itself form a routing adjacency. That observation tests a different condition, not the required result.

Unfiltered redistribution can advertise unintended internal routes. That observation tests a different condition, not the required result.

BGP attributes determine preference beyond ordinary hop count. That observation tests a different condition, not the required result.

Question 501

A multicast video service floods every port in the VLAN. Which change most directly meets this campus requirement?

Enable appropriate IGMP snooping and confirm listener groups.
Check cabling, transceiver compatibility and physical-layer faults.
Use LLDP neighbor and port descriptions instead of guessing cabling.
Prioritize important PoE ports and adjust allocation within the hardware limit.

Explanation

Correct Answer

IGMP snooping limits eligible multicast delivery to interested ports. The engineer should enable appropriate IGMP snooping and confirm listener groups.

Incorrect Answers

Frame check errors usually indicate problems below the IP layer. It is not a direct remedy for the condition described.

LLDP advertises directly connected device identity and capabilities. It is not a direct remedy for the condition described.

Power budget decisions determine which powered endpoints receive sufficient wattage. It is not a direct remedy for the condition described.

Question 502

After completing the planned work for this situation—an Ethernet trunk's throughput stays low despite two LAG members—how should success be checked?

Run multiple varied flows and inspect member counters.
Compare RTP jitter with queue occupancy after tuning.
Capture DSCP and inspect queue maps on the bottleneck switch.
Measure association RSSI at roam and compare before/after tuning.

Explanation

Correct Answer

LAG hashing keeps a flow on one member and does not split one flow packet by packet. Run multiple varied flows and inspect member counters directly tests the desired behavior.

Incorrect Answers

Full link saturation exposes serialization and queuing delays. That observation tests a different condition, not the required result.

Classification and queue scheduling both matter for end-to-end QoS. That observation tests a different condition, not the required result.

Excess power can delay client roaming despite good RSSI. That observation tests a different condition, not the required result.

Question 503

A network team reports the following condition: A security design needs role-based policy rather than one VLAN per job title. Select the most appropriate response.

Enable WPA3/PMF on compatible SSIDs.
Map authenticated identities to suitable Aruba user roles.
Enable authorized rogue/neighbor AP monitoring and validate classifications.
Use SNMPv3 authentication and privacy where supported.

Explanation

Correct Answer

Roles can express differentiated access independent of separate SSID proliferation. The engineer should map authenticated identities to suitable Aruba user roles.

Incorrect Answers

Protected management frames prevent unauthenticated robust management manipulation. It is not a direct remedy for the condition described.

Wireless intrusion monitoring distinguishes trusted infrastructure from unknown transmitters. It is not a direct remedy for the condition described.

SNMPv3 can authenticate and encrypt management telemetry. It is not a direct remedy for the condition described.

Question 504

An engineer is planning corrective work because a voice client roams and loses packets despite good RSSI on both APs. Which step should be prioritized?

Inspect EAP/TLS trust and expiration before changing WLAN channels.
Correlate logs, topology changes and historical telemetry around the failure time.
Check negotiated PoE class and switch power availability.
Correlate roam events, authentication timing and application jitter.

Explanation

Correct Answer

Fast RF association and data-plane continuity are different measures. The engineer should correlate roam events, authentication timing and application jitter.

Incorrect Answers

Certificate validation occurs after the client discovers the SSID. It is not a direct remedy for the condition described.

End-state snapshots may miss transient faults. It is not a direct remedy for the condition described.

Insufficient PoE can cause reduced AP functionality while link remains up. It is not a direct remedy for the condition described.

Question 505

Following a campus change for this issue—a new classroom WLAN has weak 5 GHz coverage at the far wall—which result most directly verifies that the remedy works?

Measure client RSSI/SNR and throughput at the coverage edge.
Measure time to discover the WLAN with and without supported discovery assistance.
Observe client capability and uplink channel utilization during small-packet traffic.
Compare channel maps and CCI before and after channel changes.

Explanation

Correct Answer

Usable wireless coverage depends on geometry, attenuation and client receive sensitivity. Measure client RSSI/SNR and throughput at the coverage edge directly tests the desired behavior.

Incorrect Answers

6 GHz discovery procedures differ from legacy 2.4/5 GHz behavior. That observation tests a different condition, not the required result.

OFDMA divides airtime into resource units for efficient multi-user scheduling. That observation tests a different condition, not the required result.

Overlapping 2.4 GHz cells contend and interfere on shared channels. That observation tests a different condition, not the required result.

Question 506

Following a campus change for this issue—an AP's automatic power setting leaves sticky clients—which result most directly verifies that the remedy works?

Compare channel occupancy and performance at 20/40/80 MHz.
Measure uplink RSSI/SNR at AP and retry counters.
Measure association RSSI at roam and compare before/after tuning.
Compare RTT, retransmissions and goodput on the live path.

Explanation

Correct Answer

Excess power can delay client roaming despite good RSSI. Measure association RSSI at roam and compare before/after tuning 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.

AP downlink power may exceed handheld uplink capability. That observation tests a different condition, not the required result.

Wide-area throughput is constrained by latency, loss and congestion. That observation tests a different condition, not the required result.

Question 507

A technician has applied this fix: Examine errdisable or protection events before re-enabling. Which observation would provide the strongest acceptance evidence?

Trace host default gateway resolution and routed forwarding between VLANs.
Correlate event log timestamp with port status and offending traffic.
Verify root bridge ID and root port selections across the VLAN instances.
Capture tagged traffic and compare allowed VLAN lists on each end.

Explanation

Correct Answer

An automatic protection feature may be intentionally shutting the port. Correlate event log timestamp with port status and offending traffic directly tests the desired behavior.

Incorrect Answers

VLAN creation alone provides Layer 2 membership, not inter-VLAN routing. That observation tests a different condition, not the required result.

Spanning-tree root selection must reflect the planned campus topology. That observation tests a different condition, not the required result.

An 802.1Q trunk transports multiple logical Ethernet networks. That observation tests a different condition, not the required result.

Question 508

Connect an approved and unregistered printer MAC and compare roles.
Review RADIUS packet outcome and switch auth-session reason.
Capture EAPOL at the port and UDP RADIUS toward the server.
Compare a trusted and unknown-CA client authentication result.

Explanation

Correct Answer

EAP-TLS succeeds only with a valid trusted certificate chain. Compare a trusted and unknown-CA client authentication result directly tests the desired behavior.

Incorrect Answers

MAB can accommodate legacy devices but offers weaker identity assurance. That observation tests a different condition, not the required result.

Server reachability and credential validation produce different failure evidence. That observation tests a different condition, not the required result.

EAPOL client traffic still needs the authenticator to reach RADIUS. That observation tests a different condition, not the required result.

Question 509

An engineer is planning corrective work because a switch authenticates a downstream unmanaged switch but all attached devices become trusted. Which step should be prioritized?

Choose client-mode authentication rather than one-device blanket authorization.
Align the authenticated RADIUS client secret at both endpoints.
Correct server identity/SAN to match client trust expectations.
Assign a reject/deny role rather than treating reject as timeout.

Explanation

Correct Answer

Client-mode authenticates connected clients individually where supported. The engineer should choose client-mode authentication rather than one-device blanket authorization.

Incorrect Answers

RADIUS integrity checks depend on matching shared secrets. It is not a direct remedy for the condition described.

Supplicants may reject a server even when its signing CA is trusted. It is not a direct remedy for the condition described.

An explicit Access-Reject differs from a server communication failure. It is not a direct remedy for the condition described.

Question 510

Following a campus change for this issue—a campus voice class suffers under uplink congestion—which result most directly verifies that the remedy works?

Compare packet latency/loss with a bandwidth test in the same interval.
Compare throughput and drop profiles before and after rate control.
Generate voice and bulk traffic and measure jitter/queue drops.
Compare channel occupancy and performance at 20/40/80 MHz.

Explanation
