HP HPE7-A01 Practice Test 33

Question 320

A network team reports the following condition: A PoE access switch has 48 AP/phone endpoints and insufficient capacity. Select the most appropriate response.

Check device inventory, subscription assignment and outbound management reachability.
Budget total power draw before enabling all powered ports.
Align the LACP actor/partner mode and member compatibility.
Provide a supported voice VLAN and separate data-network authorization.

Explanation

Correct Answer

A shared PoE power budget can limit the number of fully powered endpoints. The engineer should budget total power draw before enabling all powered ports.

Incorrect Answers

Cloud onboarding requires identity, entitlement and network communication, not only an IP address. It is not a direct remedy for the condition described.

A LAG requires compatible peer negotiation and member parameters. It is not a direct remedy for the condition described.

Voice and data traffic can share a port while retaining distinct VLAN and policy treatment. It is not a direct remedy for the condition described.

Question 321

A technician has applied this fix: Configure a trunk with the required allowed VLANs. Which observation would provide the strongest acceptance evidence?

Follow VLAN membership from phone access port to its routed SVI.
Compare MSTP digest and instance-to-VLAN tables on both switches.
Capture tagged traffic and compare allowed VLAN lists on each end.
Compare per-member LACP state and active aggregate capacity.

Explanation

Correct Answer

An 802.1Q trunk transports multiple logical Ethernet networks. Capture tagged traffic and compare allowed VLAN lists on each end directly tests the desired behavior.

Incorrect Answers

VLAN admission must exist on every necessary trunk in the path. That observation tests a different condition, not the required result.

MSTP region agreement is required for consistent internal topology calculation. That observation tests a different condition, not the required result.

All participating LAG members must negotiate compatible operation. That observation tests a different condition, not the required result.

Question 322

During campus implementation, an internal server VLAN must be advertised in OSPF without neighbor discovery on user ports. What should the engineer configure or correct?

Enable compatible OSPF participation on the proper L3 interfaces.
Set appropriate OSPF interface priority where supported.
Use supported NSSA external route handling instead of ordinary stub settings.
Make user-facing OSPF interfaces passive while advertising the prefix.

Explanation

Correct Answer

Passive OSPF suppresses adjacency exchange on the selected interface. The engineer should make user-facing OSPF interfaces passive while advertising the prefix.

Incorrect Answers

VPN tunnel establishment does not itself form a routing adjacency. It is not a direct remedy for the condition described.

DR election considers priority before router-ID tiebreaking. It is not a direct remedy for the condition described.

NSSA permits controlled local external redistribution in a stub-like area. It is not a direct remedy for the condition described.

Question 323

During campus implementation, an IGMP snooping VLAN has no querier and multicast membership ages unexpectedly. What should the engineer configure or correct?

Inspect LLDP-MED voice policy and endpoint support.
Apply management-plane ACL/RBAC and secure protocols.
Align link negotiation and duplex compatibility.
Ensure a reachable IGMP querier exists in that VLAN.

Explanation

Correct Answer

IGMP group maintenance requires periodic membership queries. The engineer should ensure a reachable IGMP querier exists in that VLAN.

Incorrect Answers

LLDP-MED can communicate voice VLAN and QoS settings to phones. It is not a direct remedy for the condition described.

Administrative access protection is distinct from normal endpoint forwarding. 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 324

Following a campus change for this issue—wi-Fi retry rates rise only when neighboring APs become busy—which result most directly verifies that the remedy works?

Test the affected user certificate against a known-good endpoint.
Capture DHCP DORA and inspect client VLAN.
Correlate channel utilization and retry peaks.
Perform a peak-hour RF survey and a quiet-hour comparison.

Explanation

Correct Answer

Competing transmitters on the same channel can drive delay and retries. Correlate channel utilization and retry peaks directly tests the desired behavior.

Incorrect Answers

Per-endpoint authentication problems are not necessarily switch-wide faults. That observation tests a different condition, not the required result.

Association and authentication are separate from address assignment. That observation tests a different condition, not the required result.

Time-correlated environmental changes can explain periodic performance drops. That observation tests a different condition, not the required result.

Question 325

The engineer reports completing this change: Align the authenticated RADIUS client secret at both endpoints. Which verification should be included in the handover?

Inspect policy hit and role applied on the switch.
Inspect server logs for authenticator failures and retest.
Compare a trusted and unknown-CA client authentication result.
Attempt authentication with a revoked test certificate.

Explanation

Correct Answer

RADIUS integrity checks depend on matching shared secrets. Inspect server logs for authenticator failures and retest 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.

EAP-TLS succeeds only with a valid trusted certificate chain. That observation tests a different condition, not the required result.

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

Question 326

A technician has applied this fix: Re-mark untrusted traffic at the first managed boundary. Which observation would provide the strongest acceptance evidence?

Capture DSCP and inspect queue maps on the bottleneck switch.
Send a test packet with false priority and inspect egress marking.
Compare queue depth and latency during a backup transfer.
Track per-station airtime and edge connectivity before/after adjustment.

Explanation

Correct Answer

QoS trust should be granted to known sources, not arbitrary clients. Send a test packet with false priority and inspect egress marking directly tests the desired behavior.

Incorrect Answers

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

Long egress queues create delay and jitter under sustained overload. That observation tests a different condition, not the required result.

Low PHY rates consume more airtime for each transmitted byte. That observation tests a different condition, not the required result.

Question 327

A network team reports the following condition: A new NAE script monitors only one interface while faults occur on another. Select the most appropriate response.

Adjust the monitored resource and alert conditions.
Use Central device health, inventory and telemetry views.
Enable adequate configuration logging, backups and change records.
Use supported port mirroring to a capture destination.

Explanation

Correct Answer

An analytics agent evaluates the configured monitored objects, not every port automatically. The engineer should adjust the monitored resource and alert conditions.

Incorrect Answers

Central management correlates device-level state across groups/sites. It is not a direct remedy for the condition described.

Logs and configuration diffs help identify who changed what and when. It is not a direct remedy for the condition described.

Mirroring copies selected interface traffic for protocol analysis. It is not a direct remedy for the condition described.

Question 328

An engineer is planning corrective work because a site shows intermittent errors but the current counters look normal. Which step should be prioritized?

Verify physical media, transceiver type and optical signal before routing.
Find the exact matching ACE and its direction before broad changes.
Check MTU, network type and adjacency negotiation.
Correlate logs, topology changes and historical telemetry around the failure time.

Explanation

Correct Answer

End-state snapshots may miss transient faults. The engineer should correlate logs, topology changes and historical telemetry around the failure time.

Incorrect Answers

Layer 1 failure must be resolved before Layer 3 diagnosis. It is not a direct remedy for the condition described.

ACL ordering and attachment point determine real packet authorization. It is not a direct remedy for the condition described.

OSPF DBD exchange can be impeded by incompatible link parameters. It is not a direct remedy for the condition described.

Question 329

A certificate-based WLAN fails when server certificate expires. Which change most directly meets this campus requirement?

Apply quarantine/deny role based on verified endpoint status.
Refine the guest policy with explicit application and destination constraints.
Renew the certificate and restore supported client trust.
Apply STP root or BPDU protection on appropriate edge ports.

Explanation

Correct Answer

EAP validation rejects expired or untrusted authentication servers. The engineer should renew the certificate and restore supported client trust.

Incorrect Answers

Enforcement should follow authenticated context rather than an unverified MAC alone. It is not a direct remedy for the condition described.

Generic allow rules can undermine network separation. It is not a direct remedy for the condition described.

STP protections constrain unauthorized topology control. It is not a direct remedy for the condition described.

Question 330

The engineer reports completing this change: Check role transition, DNS, gateway and redirect policies. Which verification should be included in the handover?

Correlate radar event logs with AP channel changes and reconnect times.
Measure client RSSI/SNR and throughput at the coverage edge.
Compare association band, noise and retry rates for affected clients.
Compare pre-login and post-login client-role traffic captures.

Explanation

Correct Answer

Portal authentication must result in a usable authorized forwarding role. Compare pre-login and post-login client-role traffic captures directly tests the desired behavior.

Incorrect Answers

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

Usable wireless coverage depends on geometry, attenuation and client receive sensitivity. 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.
