HP HPE7-A01 Practice Test 38

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.

Question 371

For an HPE Aruba Networking campus deployment, an intermittent application failure needs packet-level proof. Which action best addresses it?

Compare RF interference, client density and scheduled activities by time.
Capture on an appropriate mirrored port and correlate timestamps.
Scope by device, SSID, VLAN and location before changing global policy.
Inspect MAC table learning and potential port-security blocking.

Explanation

Correct Answer

Packet capture distinguishes transport retransmissions, resets and filtering. The engineer should capture on an appropriate mirrored port and correlate timestamps.

Incorrect Answers

Time-correlated environmental changes can explain periodic performance drops. It is not a direct remedy for the condition described.

Fault isolation starts by defining the smallest affected domain. It is not a direct remedy for the condition described.

Layer 2 forwarding depends on learned destination MAC and permitted ports. It is not a direct remedy for the condition described.

Question 372

A network team reports the following condition: A client fails EAP-TLS because its certificate lacks the right identity mapping. Select the most appropriate response.

Use supported RADIUS CoA or reauthorization workflow.
Enable supported RADIUS accounting independently of authentication.
Correct certificate identity and RADIUS mapping policy.
Fix the returned VLAN/role attributes and effective enforcement settings.

Explanation

Correct Answer

Authorization must map the authenticated certificate identity to the intended user/device. The engineer should correct certificate identity and RADIUS mapping policy.

Incorrect Answers

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

Accounting records session events rather than selecting the identity. It is not a direct remedy for the condition described.

Authentication success and assigned authorization policy are separate decisions. It is not a direct remedy for the condition described.

Question 373

An AP has excellent RSSI but poor SNR near heavy machinery. Which change most directly meets this campus requirement?

Tune scheduling, shaping and available path capacity.
Calibrate cell-edge target and neighboring AP power.
Reduce noise/interference or reposition the cell.
Classify and prioritize the voice traffic in the appropriate egress queues.

Explanation

Correct Answer

SNR combines received signal strength with background noise. The engineer should reduce noise/interference or reposition the cell.

Incorrect Answers

Long egress queues create delay and jitter under sustained overload. It is not a direct remedy for the condition described.

Excess power can delay client roaming despite good RSSI. It is not a direct remedy for the condition described.

QoS scheduling helps latency-sensitive packets compete under load. It is not a direct remedy for the condition described.

Question 374

The engineer reports completing this change: Validate the AP wired-port bridge mode, allowed VLAN and required access policy. Which verification should be included in the handover?

Verify device inventory status, DNS reachability and connection diagnostics.
Compare DHCP lease history, ARP entries and management syslogs.
Inspect negotiated media speed and both sides' interface counters.
Test IoT port authorization and VLAN-specific reachability.

Explanation

Correct Answer

The AP uplink does not automatically grant all attached wired port traffic. Test IoT port authorization and VLAN-specific reachability directly tests the desired behavior.

Incorrect Answers

Cloud onboarding requires identity, entitlement and network communication, not only an IP address. That observation tests a different condition, not the required result.

Duplicate management addresses or unstable DHCP assignments break control-plane reachability. That observation tests a different condition, not the required result.

Link establishment depends on mutually supported PHY settings. That observation tests a different condition, not the required result.

Question 375

During campus implementation, an auditorium has strong RSSI but low WLAN throughput during a conference. What should the engineer configure or correct?

Inspect channel airtime usage, co-channel interference and retry rates.
Prefer appropriately designed 5 GHz service where clients support it.
Use WPA3-SAE with compatible client support.
Check client and AP capability and actual MU transmission support.

Explanation

Correct Answer

Strong signal alone does not guarantee available airtime. The engineer should inspect channel airtime usage, co-channel interference and retry rates.

Incorrect Answers

The 5 GHz band offers more usable channel choices and often less 2.4 GHz interference. It is not a direct remedy for the condition described.

SAE provides password-based authenticated key exchange without legacy WPA2-PSK semantics. It is not a direct remedy for the condition described.

MU-MIMO performance depends on device capabilities and RF conditions. It is not a direct remedy for the condition described.

Question 376

The campus team is closing a service ticket about this condition: A phone connects to an access port but the switch does not identify it as a phone. Which validation step is most relevant?

Observe LACP protocol exchange after changing one member to active.
Run management-VRF sourced ping and route lookup to the cloud endpoint.
Examine route lookup and path traces with primary connectivity disabled safely.
Compare switch LLDP neighbor detail and the phone's advertised capabilities.

Explanation

Correct Answer

LLDP-MED exchanges device and voice-network capability information. Compare switch LLDP neighbor detail and the phone's advertised capabilities directly tests the desired behavior.

Incorrect Answers

Passive LACP endpoints do not initiate the exchange needed to negotiate a bundle. That observation tests a different condition, not the required result.

A reachable local interface does not imply a usable route from the management VRF. That observation tests a different condition, not the required result.

Physical carrier state is distinct from an installed usable route. That observation tests a different condition, not the required result.

Question 377

The campus team is closing a service ticket about this condition: A policy should stop access from a device that repeatedly fails posture. Which validation step is most relevant?

Verify malicious-status test input yields a restricted role.
Compare effective role and permitted flows for approved and denied clients.
Inject high-marked guest traffic and observe effective egress class.
Test guest-to-finance denial and guest internet allowance.

Explanation

Correct Answer

Enforcement should follow authenticated context rather than an unverified MAC alone. Verify malicious-status test input yields a restricted role directly tests the desired behavior.

Incorrect Answers

Port access control restricts network membership to authenticated endpoints. That observation tests a different condition, not the required result.

Untrusted clients can self-mark traffic to obtain an undeserved priority. That observation tests a different condition, not the required result.

VLAN placement by itself may not enforce the intended least privilege. That observation tests a different condition, not the required result.

Question 378

A technician has applied this fix: Apply dedicated management segmentation and source filtering. Which observation would provide the strongest acceptance evidence?

Simulate RADIUS outage and observe the assigned critical role.
Compare effective role and permitted flows for approved and denied clients.
Verify guest cannot reach management ports while ops clients can.
Compare approved AP inventory with detected BSSID and security settings.

Explanation

Correct Answer

Controller/AP administration must be protected from public client VLANs. Verify guest cannot reach management ports while ops clients can directly tests the desired behavior.

Incorrect Answers

Authentication outages need controlled failover permissions. That observation tests a different condition, not the required result.

Port access control restricts network membership to authenticated endpoints. That observation tests a different condition, not the required result.

Wireless intrusion monitoring distinguishes trusted infrastructure from unknown transmitters. That observation tests a different condition, not the required result.

Question 379

A technician has applied this fix: Assign a reject/deny role rather than treating reject as timeout. Which observation would provide the strongest acceptance evidence?

Compare reject-role and critical-role results in a controlled test.
Inspect policy hit and role applied on the switch.
Compare profiling result and effective role on both switches.
Review start, interim and stop accounting messages for a session.

Explanation

Correct Answer

An explicit Access-Reject differs from a server communication failure. Compare reject-role and critical-role results in a controlled test directly tests the desired behavior.

Incorrect Answers

Identity validation must be followed by explicit authorization attributes. That observation tests a different condition, not the required result.

Device category and enforcement mapping must follow endpoint identity across locations. 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 380

Following a campus change for this issue—two tenants reuse 10.0.0.0/8 and must stay isolated—which result most directly verifies that the remedy works?

Compare chosen next hop for two addresses in different prefix lengths.
Display both identical routes in distinct VRFs and test isolation.
Capture relay source and server replies for the client VLAN.
Inspect received default and chosen route after policy evaluation.

Explanation

Correct Answer

VRFs maintain independent route tables and overlapping address space. Display both identical routes in distinct VRFs and test isolation directly tests the desired behavior.

Incorrect Answers

More-specific prefixes normally override less-specific matches in route lookup. That observation tests a different condition, not the required result.

DHCP broadcasts require relay when the server is beyond a router. That observation tests a different condition, not the required result.

Route import policy can protect internal next-hop expectations. That observation tests a different condition, not the required result.
