HP HPE7-A01 Practice Test 37

Question 360

An application works in a lab but performs poorly across a busy WAN. Which change most directly meets this campus requirement?

Consider supported airtime fairness and data-rate policy.
Re-mark untrusted traffic at the first managed boundary.
Measure end-to-end bottleneck, TCP window and path loss rather than only switch port speed.
Reduce noise/interference or reposition the cell.

Explanation

Correct Answer

Wide-area throughput is constrained by latency, loss and congestion. The engineer should measure end-to-end bottleneck, TCP window and path loss rather than only switch port speed.

Incorrect Answers

Equal byte throughput is not the same as equal shared radio airtime. It is not a direct remedy for the condition described.

QoS trust should be granted to known sources, not arbitrary clients. It is not a direct remedy for the condition described.

SNR combines received signal strength with background noise. It is not a direct remedy for the condition described.

Question 361

An engineer is planning corrective work because an AP hears many neighboring WLANs but clients have acceptable SNR. Which step should be prioritized?

Differentiate same-channel contention from adjacent-channel interference.
Prefer role-based policy where it reduces unnecessary SSID proliferation.
Check role transition, DNS, gateway and redirect policies.
Consider narrower channels and a more suitable reuse plan.

Explanation

Correct Answer

CCI shares airtime while ACI disrupts reception through overlapping energy. The engineer should differentiate same-channel contention from adjacent-channel interference.

Incorrect Answers

Distinct policy does not always require a new beaconing SSID. It is not a direct remedy for the condition described.

Portal authentication must result in a usable authorized forwarding role. It is not a direct remedy for the condition described.

Wider channels can increase overlap and reduce available independent cells. It is not a direct remedy for the condition described.

Question 362

New access switches require repeatable configuration at dozens of sites. Which change most directly meets this campus requirement?

Check stack link topology and supported redundant member cabling.
Assign them to the appropriate Central group or template scope.
Configure reachable DNS resolvers with the required records.
Enable suitable LLDP-MED advertisements and examine neighbor capabilities.

Explanation

Correct Answer

A management group determines the policy and configuration applied to its devices. The engineer should assign them to the appropriate Central group or template scope.

Incorrect Answers

A resilient stack topology avoids relying on one physical intermember path. It is not a direct remedy for the condition described.

Control-plane enrollment can fail when hostnames cannot resolve correctly. It is not a direct remedy for the condition described.

LLDP-MED exchanges device and voice-network capability information. It is not a direct remedy for the condition described.

Question 363

An engineer is planning corrective work because a dense WLAN shows high channel utilization from a small number of slow stations. Which step should be prioritized?

Use scoped certificate-level controls without unauthorized TLS payload inspection.
Differentiate same-channel contention from adjacent-channel interference.
Investigate airtime fairness and legacy data-rate impact.
Validate supported AP uplink failover and matching VLAN availability on the alternate port.

Explanation

Correct Answer

A slow client can occupy much airtime for comparatively few bytes. The engineer should investigate airtime fairness and legacy data-rate impact.

Incorrect Answers

Certificate visibility and full decryption have different privacy implications. It is not a direct remedy for the condition described.

CCI shares airtime while ACI disrupts reception through overlapping energy. It is not a direct remedy for the condition described.

AP resiliency requires compatible management and user VLAN reachability after switching links. It is not a direct remedy for the condition described.

Question 364

An engineer is planning corrective work because a switch port has output discards while there are few CRC errors. Which step should be prioritized?

Trust only approved voice marking and map traffic to suitable egress queues.
Review spanning-tree role, topology changes and loop-guard features.
Align link negotiation and duplex compatibility.
Investigate egress congestion and queue utilization.

Explanation

Correct Answer

Output drops can arise from queue pressure even without physical corruption. The engineer should investigate egress congestion and queue utilization.

Incorrect Answers

QoS classification and queue maps control congestion behavior. It is not a direct remedy for the condition described.

Redundant physical links must not create an uncontrolled bridging loop. It is not a direct remedy for the condition described.

Duplex mismatch can create collisions and poor performance. It is not a direct remedy for the condition described.

Question 365

During campus implementation, a client certificate is signed by an unknown CA. What should the engineer configure or correct?

Distinguish server timeout from Access-Reject during troubleshooting.
Use MAC-based authentication with a restricted printer role.
Repair RADIUS server address, VRF route or server group configuration.
Install the required trust anchor or replace the untrusted certificate.

Explanation

Correct Answer

EAP-TLS succeeds only with a valid trusted certificate chain. The engineer should install the required trust anchor or replace the untrusted certificate.

Incorrect Answers

Server reachability and credential validation produce different failure evidence. It is not a direct remedy for the condition described.

MAB can accommodate legacy devices but offers weaker identity assurance. It is not a direct remedy for the condition described.

EAPOL client traffic still needs the authenticator to reach RADIUS. It is not a direct remedy for the condition described.

Question 366

After completing the planned work for this situation—a voice endpoint shares a port with an employee laptop—how should success be checked?

Attempt authentication with a revoked test certificate.
Test phone and laptop simultaneously with separate authorizations.
Disconnect RADIUS and inspect critical-role policy.
Review start, interim and stop accounting messages for a session.

Explanation

Correct Answer

Phone and data station may require separate access identities and roles. Test phone and laptop simultaneously with separate authorizations directly tests the desired behavior.

Incorrect Answers

A valid-looking certificate may no longer be authorized after revocation. That observation tests a different condition, not the required result.

A RADIUS outage should not imply blanket production access. That observation tests a different condition, not the required result.

Accounting records session events rather than selecting the identity. That observation tests a different condition, not the required result.

Question 367

Following a campus change for this issue—a switch has an unwanted Layer 2 flooding path after a physical rewire—which result most directly verifies that the remedy works?

Trace host default gateway resolution and routed forwarding between VLANs.
Inspect the LACP partner system IDs and selected member states.
Inspect topology-change counters and identify the blocking port.
Confirm static route active state and VRF-specific adjacency.

Explanation

Correct Answer

Redundant physical links must not create an uncontrolled bridging loop. Inspect topology-change counters and identify the blocking port 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.

Plain LACP assumes one logical partner; independent switches cannot be arbitrarily combined. 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 368

The campus team is closing a service ticket about this condition: A roaming design needs to discover neighbor APs efficiently. Which validation step is most relevant?

Compare airtime share and goodput by client PHY rate.
Measure concurrent client distribution and busy time per radio.
Inspect neighbor-report responses during a controlled roam.
Compare negotiated PHY capabilities with airtime efficiency.

Explanation

Correct Answer

Neighbor reports can reduce the amount of blind scanning needed. Inspect neighbor-report responses during a controlled roam directly tests the desired behavior.

Incorrect Answers

A slow client can occupy much airtime for comparatively few bytes. That observation tests a different condition, not the required result.

Capacity is constrained by shared airtime, not simply signal strength. That observation tests a different condition, not the required result.

Legacy clients cannot use HE-only scheduling features. That observation tests a different condition, not the required result.

Question 369

The engineer reports completing this change: Check platform ECMP settings and route eligibility. Which verification should be included in the handover?

Inspect RIB/FIB and reason for next-hop exclusion.
Verify no user-port hellos and continued prefix advertisement.
Trace multicast routes and receiver memberships.
Look up the route and ping the next hop from the right VRF.

Explanation

Correct Answer

Multiple configured next hops do not guarantee equal-cost installation. Inspect RIB/FIB and reason for next-hop exclusion directly tests the desired behavior.

Incorrect Answers

Passive OSPF suppresses adjacency exchange on the selected interface. That observation tests a different condition, not the required result.

Multicast forwarding requires a forwarding tree and interested receivers. That observation tests a different condition, not the required result.

Static forwarding requires the destination prefix and next-hop resolution. That observation tests a different condition, not the required result.

Question 370

After completing the planned work for this situation—the voice VLAN is not passed across the aggregation uplink—how should success be checked?

Inspect the VLAN's forwarding members and SVI up/down state.
Correlate MAC move events with port counters and topology.
Follow VLAN membership from phone access port to its routed SVI.
Verify edge state and response when a BPDU is received.

Explanation

Correct Answer

VLAN admission must exist on every necessary trunk in the path. Follow VLAN membership from phone access port to its routed SVI directly tests the desired behavior.

Incorrect Answers

An SVI may depend on its VLAN being operationally active. That observation tests a different condition, not the required result.

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

Edge semantics reduce startup delay but should not blindly trust bridge devices. That observation tests a different condition, not the required result.
