HP HPE7-A01 Practice Test 53

Question 520

After completing the planned work for this situation—an 802.1X reauthentication setting disconnects voice calls too frequently—how should success be checked?

Measure call behavior across a scheduled reauthentication cycle.
Inspect supplicant TLS alert and server-name validation.
Test both capable and non-802.1X endpoints and inspect selected method.
Attempt an allowed and restricted CLI operation for a test admin.

Explanation

Correct Answer

Unnecessarily aggressive reauthentication can disrupt real-time sessions. Measure call behavior across a scheduled reauthentication cycle directly tests the desired behavior.

Incorrect Answers

Supplicants may reject a server even when its signing CA is trusted. That observation tests a different condition, not the required result.

Auth-method priority avoids bypassing strong identities prematurely. That observation tests a different condition, not the required result.

Authentication identifies administrators; authorization controls permitted commands. That observation tests a different condition, not the required result.

Question 521

The campus team is closing a service ticket about this condition: A data uplink suffers large queues during backup hours. Which validation step is most relevant?

Compare throughput and drop profiles before and after rate control.
Measure multicast loss and radio airtime during stream replication.
Compare queue depth and latency during a backup transfer.
Measure uplink RSSI/SNR at AP and retry counters.

Explanation

Correct Answer

Long egress queues create delay and jitter under sustained overload. Compare queue depth and latency during a backup transfer directly tests the desired behavior.

Incorrect Answers

Shaping buffers over-rate traffic while policing can drop or remark it. 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.

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

Question 522

The campus team is closing a service ticket about this condition: A fault appears after a recent configuration rollout. Which validation step is most relevant?

Compare DNS lookup with direct IP connectivity.
Inspect optic diagnostics and both ends' link state.
Correlate channel utilization and retry peaks.
Revert one safe test change and verify incident symptoms.

Explanation

Correct Answer

Change correlation narrows likely causes without assuming every recent edit is wrong. Revert one safe test change and verify incident symptoms directly tests the desired behavior.

Incorrect Answers

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

Layer 1 failure must be resolved before Layer 3 diagnosis. That observation tests a different condition, not the required result.

Competing transmitters on the same channel can drive delay and retries. That observation tests a different condition, not the required result.

Question 523

A technician has applied this fix: Check the relevant root-guard role on that uplink. Which observation would provide the strongest acceptance evidence?

Offer DHCP from trusted and untrusted sides and inspect counters.
Inject a superior BPDU in a lab and inspect guard state.
Compare ingress broadcast rate before and after a controlled storm fixture.
Compare neighbor chassis/port IDs with the patching schedule.

Explanation

Correct Answer

Root guard prevents an unplanned switch from taking over the root position. Inject a superior BPDU in a lab and inspect guard state directly tests the desired behavior.

Incorrect Answers

DHCP snooping blocks unauthorized server replies on untrusted ports. That observation tests a different condition, not the required result.

Storm control limits excess broadcast or multicast traffic while loops are fixed. That observation tests a different condition, not the required result.

LLDP advertises directly connected device identity and capabilities. That observation tests a different condition, not the required result.

Question 524

The campus team is closing a service ticket about this condition: A switch management SVI responds locally but cannot reach Central across the WAN. Which validation step is most relevant?

Compare connected routes, ARP for the gateway and management subnet plan.
Run management-VRF sourced ping and route lookup to the cloud endpoint.
Capture the first management exchange and inspect uplink VLAN settings.
Check LLDP-MED voice information and both endpoints' effective VLANs.

Explanation

Correct Answer

A reachable local interface does not imply a usable route from the management VRF. Run management-VRF sourced ping and route lookup to the cloud endpoint directly tests the desired behavior.

Incorrect Answers

Incorrect address/prefix selection prevents ordinary management routing. That observation tests a different condition, not the required result.

AP management requires consistent tagged versus untagged treatment. That observation tests a different condition, not the required result.

Voice and data traffic can share a port while retaining distinct VLAN and policy treatment. That observation tests a different condition, not the required result.

Question 525

An engineer is planning corrective work because a campus has multiple VLAN groups with different preferred redundant paths. Which step should be prioritized?

Establish an eligible backup route and failure detection method.
Use supported BFD where it is interoperable with the routing protocol.
Check the inter-switch link connectivity and VSX state.
Map VLANs to supported MSTP instances with appropriate roots.

Explanation

Correct Answer

MSTP can provide separate spanning-tree topologies for groups of VLANs. The engineer should map VLANs to supported MSTP instances with appropriate roots.

Incorrect Answers

Redundancy requires more than an unused physical interface. It is not a direct remedy for the condition described.

BFD provides fast liveliness information separate from normal route timers. It is not a direct remedy for the condition described.

The VSX inter-switch link carries peer coordination and state traffic. It is not a direct remedy for the condition described.

Question 526

For an HPE Aruba Networking campus deployment, a campus bridge has a broadcast storm after a patch-cable mistake. Which action best addresses it?

Investigate egress congestion and queue utilization.
Apply supported port-security learning and violation handling.
Configure storm-control thresholds and loop prevention as appropriate.
Use a supported RA Guard policy on untrusted access ports.

Explanation

Correct Answer

Storm control limits excess broadcast or multicast traffic while loops are fixed. The engineer should configure storm-control thresholds and loop prevention as appropriate.

Incorrect Answers

Output drops can arise from queue pressure even without physical corruption. It is not a direct remedy for the condition described.

Port security restricts which endpoint MAC addresses can use the link. It is not a direct remedy for the condition described.

RA Guard filters unauthorized IPv6 router announcements. It is not a direct remedy for the condition described.

Question 527

A technician has applied this fix: Tune threshold/timing while preserving raw telemetry. Which observation would provide the strongest acceptance evidence?

Compare event volume and real fault visibility after tuning.
Restore in a test environment and compare intended interfaces/policies.
Capture mirrored packets and validate the intended source/direction.
Compare synthetic latency, packet loss and client radio metrics.

Explanation

Correct Answer

Alert policy can be refined without losing underlying monitoring data. Compare event volume and real fault visibility after tuning directly tests the desired behavior.

Incorrect Answers

Recovery requires a known-good configuration and compatible restore method. That observation tests a different condition, not the required result.

Mirroring copies selected interface traffic for protocol analysis. That observation tests a different condition, not the required result.

Good RSSI does not prove application-path quality. That observation tests a different condition, not the required result.

Question 528

A technician has applied this fix: Align link negotiation and duplex compatibility. Which observation would provide the strongest acceptance evidence?

Test host-to-host and host-to-gateway reachability for each port role.
Compare per-port drawn/allocated power with remaining switch capacity.
Confirm static route active state and VRF-specific adjacency.
Check both peers' negotiated duplex and error counters.

Explanation

Correct Answer

Duplex mismatch can create collisions and poor performance. Check both peers' negotiated duplex and error counters directly tests the desired behavior.

Incorrect Answers

Private VLAN constructs isolate hosts within a shared IP subnet. That observation tests a different condition, not the required result.

Power budget decisions determine which powered endpoints receive sufficient wattage. That observation tests a different condition, not the required result.

Route installation and next-hop resolution are per routing context. That observation tests a different condition, not the required result.

Question 529

A network team reports the following condition: A phone connects to an access port but the switch does not identify it as a phone. Select the most appropriate response.

Validate the management VRF default route and allowed outbound paths.
Enable suitable LLDP-MED advertisements and examine neighbor capabilities.
Configure or validate its next-hop reachability and routing policy.
Configure at least one endpoint to initiate LACP actively.

Explanation

Correct Answer

LLDP-MED exchanges device and voice-network capability information. The engineer should enable suitable LLDP-MED advertisements and examine neighbor capabilities.

Incorrect Answers

A reachable local interface does not imply a usable route from the management VRF. It is not a direct remedy for the condition described.

Physical carrier state is distinct from an installed usable route. It is not a direct remedy for the condition described.

Passive LACP endpoints do not initiate the exchange needed to negotiate a bundle. It is not a direct remedy for the condition described.

Question 530

The engineer reports completing this change: Enforce current posture result via RADIUS role/CoA policies. Which verification should be included in the handover?

Trace guest traffic against policy hits for private destinations.
Trigger an authorized posture change and observe new role permissions.
Test a permitted and denied service with policy-hit evidence.
Verify guest cannot reach management ports while ops clients can.

Explanation

Correct Answer

Dynamic authorization must reflect changing endpoint trust. Trigger an authorized posture change and observe new role permissions directly tests the desired behavior.

Incorrect Answers

Generic allow rules can undermine network separation. That observation tests a different condition, not the required result.

Least privilege limits permitted applications to approved business needs. That observation tests a different condition, not the required result.
