HP HPE7-A01 Practice Test 55

Question 540

A technician has applied this fix: Inspect channel airtime usage, co-channel interference and retry rates. Which observation would provide the strongest acceptance evidence?

Record channel utilization and per-client retries at peak attendance.
Validate SAE association and management protection in a capture.
Inspect association capabilities and observe multi-user operation counters.
Compare association band, noise and retry rates for affected clients.

Explanation

Correct Answer

Strong signal alone does not guarantee available airtime. Record channel utilization and per-client retries at peak attendance directly tests the desired behavior.

Incorrect Answers

SAE provides password-based authenticated key exchange without legacy WPA2-PSK semantics. That observation tests a different condition, not the required result.

MU-MIMO performance depends on device capabilities and RF conditions. That observation tests a different condition, not the required result.

The 5 GHz band offers more usable channel choices and often less 2.4 GHz interference. That observation tests a different condition, not the required result.

Question 541

The campus team is closing a service ticket about this condition: A redundant AP uplink needs continuity when its preferred path fails. Which validation step is most relevant?

Measure fault detection and route withdrawal during an outage pilot.
Disable one uplink and observe AP management and client continuity.
Compare SVI and active-gateway configuration on both switches.
Isolate management reachability and test existing client data flow.

Explanation

Correct Answer

Failover paths must preserve required management and client VLAN reachability. Disable one uplink and observe AP management and client continuity directly tests the desired behavior.

Incorrect Answers

BFD provides fast liveliness information separate from normal route timers. That observation tests a different condition, not the required result.

Active-gateway settings must be consistent across VSX peers. That observation tests a different condition, not the required result.

Management-plane loss should be evaluated separately from the user forwarding path. That observation tests a different condition, not the required result.

Question 542

After completing the planned work for this situation—a host needs to receive traffic on an isolated private VLAN—how should success be checked?

Show overlapping prefixes in separate VRF route tables without leakage.
Test host-to-host and host-to-gateway reachability for each port role.
Capture markings at ingress and egress and inspect queue assignment.
Compare group tables and egress multicast counters by VLAN.

Explanation

Correct Answer

Private VLAN constructs isolate hosts within a shared IP subnet. Test host-to-host and host-to-gateway reachability for each port role directly tests the desired behavior.

Incorrect Answers

VRFs provide separate Layer 3 routing contexts on one system. That observation tests a different condition, not the required result.

Marking must remain trusted through every intended QoS enforcement point. That observation tests a different condition, not the required result.

Multicast membership and Layer 2 membership are both VLAN-specific. That observation tests a different condition, not the required result.

Question 543

The campus team is closing a service ticket about this condition: A WLAN supports WPA3-Personal and must avoid shared-key downgrade. Which validation step is most relevant?

Capture beacon/SSID advertisement at the affected AP and compare group policy.
Observe neighbor reports and actual roaming decisions.
Attempt an authorized negative test and verify PMF negotiation.
Validate SAE association and management protection in a capture.

Explanation

Correct Answer

SAE provides password-based authenticated key exchange without legacy WPA2-PSK semantics. Validate SAE association and management protection in a capture directly tests the desired behavior.

Incorrect Answers

Defining an SSID centrally does not prove each AP advertises it. That observation tests a different condition, not the required result.

802.11k supplies radio neighbor information while clients decide how to use it. That observation tests a different condition, not the required result.

PMF protects specific robust management frames from unauthenticated spoofing. That observation tests a different condition, not the required result.

Question 544

A Wi-Fi client frequently retries packets despite adequate RSSI. Which change most directly meets this campus requirement?

Use scoped certificate-level controls without unauthorized TLS payload inspection.
Consider supported higher minimum data rates after coverage verification.
Balance AP power with realistic client transmit limits.
Measure SNR, interference and channel busy time.

Explanation

Correct Answer

RSSI alone cannot identify noise or contention-driven retries. The engineer should measure SNR, interference and channel busy time.

Incorrect Answers

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

Very low basic rates consume disproportionate airtime. It is not a direct remedy for the condition described.

Downlink coverage does not ensure the return path from low-power clients. It is not a direct remedy for the condition described.

Question 545

A technician has applied this fix: Confirm the AP VLAN reaches a DHCP server or relay. Which observation would provide the strongest acceptance evidence?

Capture DHCP DISCOVER/OFFER and validate access-to-uplink VLAN continuity.
Inspect member inventory, version and stack state after alignment.
Examine route lookup and path traces with primary connectivity disabled safely.
Compare planned demand, per-port allocation and system remaining budget.

Explanation

Correct Answer

Power-up and Layer 2 association alone do not ensure IP address assignment. Capture DHCP DISCOVER/OFFER and validate access-to-uplink VLAN continuity directly tests the desired behavior.

Incorrect Answers

Stack membership commonly requires compatible software and platform capabilities. 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.

A shared PoE power budget can limit the number of fully powered endpoints. That observation tests a different condition, not the required result.

Question 546

The campus team is closing a service ticket about this condition: A route change appears correct in RIB but clients still use an old path. Which validation step is most relevant?

Look up the route and ping the next hop from the right VRF.
Check intra-area and inter-area routes on each side.
Inspect OSPF neighbor state and matching hello exchanges.
Compare route, FIB and session egress for new versus old traffic.

Explanation

Correct Answer

Control-plane route updates and existing session datapaths can differ. Compare route, FIB and session egress for new versus old traffic directly tests the desired behavior.

Incorrect Answers

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

An ABR connects area 0 with additional OSPF areas. That observation tests a different condition, not the required result.

OSPF peers require compatible interface participation and topology. That observation tests a different condition, not the required result.

Question 547

A network team reports the following condition: A RADIUS timeout is incorrectly treated as an invalid password. Select the most appropriate response.

Distinguish server timeout from Access-Reject during troubleshooting.
Align the authenticated RADIUS client secret at both endpoints.
Complete the authenticated role transition and captive-portal authorization.
Configure supported TACACS+/RBAC command authorization.

Explanation

Correct Answer

Server reachability and credential validation produce different failure evidence. The engineer should distinguish server timeout from Access-Reject during troubleshooting.

Incorrect Answers

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

Portal success requires enforcement state to change before normal internet traffic. It is not a direct remedy for the condition described.

Authentication identifies administrators; authorization controls permitted commands. It is not a direct remedy for the condition described.

Question 548

An engineer is planning corrective work because a user connects an unauthorized switch and sends BPDUs into an edge port. Which step should be prioritized?

Check the relevant root-guard role on that uplink.
Enable appropriate IGMP snooping and confirm listener groups.
Find the source of MAC flapping or a Layer 2 loop.
Enable the supported BPDU protection feature on the edge.

Explanation

Correct Answer

BPDU protection can isolate ports that violate the expected edge role. The engineer should enable the supported BPDU protection feature on the edge.

Incorrect Answers

Root guard prevents an unplanned switch from taking over the root position. It is not a direct remedy for the condition described.

IGMP snooping limits eligible multicast delivery to interested ports. It is not a direct remedy for the condition described.

Rapid MAC moves may indicate a loop, duplicated host or roaming bridge. It is not a direct remedy for the condition described.

Question 549

After completing the planned work for this situation—a central wireless policy tries to steer an individual client using 802.11v—how should success be checked?

Capture BSS transition requests and the client response.
Map RSSI overlap and co-channel busy time after changes.
Match spectrum captures with the machine's operating cycle.
Compare pre-login and post-login client-role traffic captures.

Explanation

Correct Answer

802.11v can suggest a better BSS, but the client decides whether to comply. Capture BSS transition requests and the client response directly tests the desired behavior.

Incorrect Answers

Cell overlap depends on EIRP, antenna pattern and building attenuation. That observation tests a different condition, not the required result.

An intermittent interferer can explain periodic retries without any configuration change. That observation tests a different condition, not the required result.

Portal authentication must result in a usable authorized forwarding role. That observation tests a different condition, not the required result.

Question 550

The engineer reports completing this change: Consider narrower channels and a more suitable reuse plan. Which verification should be included in the handover?

Associate a new test guest and inspect portal redirect and post-login role.
Survey co-channel overlap and voice latency across the channel plan.
Correlate radar event logs with AP channel changes and reconnect times.
Inspect association capabilities and observe multi-user operation counters.

Explanation

Correct Answer

Wider channels can increase overlap and reduce available independent cells. Survey co-channel overlap and voice latency across the channel plan directly tests the desired behavior.

Incorrect Answers

Captive portals add user onboarding beyond basic association. That observation tests a different condition, not the required result.

DFS regulations require compliant devices to vacate channels after radar detection. That observation tests a different condition, not the required result.

MU-MIMO performance depends on device capabilities and RF conditions. That observation tests a different condition, not the required result.
