HP HPE7-A01 Practice Test 24

Question 230

Following a campus change for this issue—an access radio handles many clients on a shared wireless channel—which result most directly verifies that the remedy works?

Observe channel busy time and retransmissions during a controlled multi-client transfer.
Review ARP and MAC tables and capture ARP exchange for the target.
Capture frames or inspect trunk membership to verify the expected VLAN IDs.
Use a site survey to compare co-channel overlap and airtime busy percentages.

Explanation

Correct Answer

802.11 stations contend for shared airtime, so carrier-sense and backoff affect throughput. Observe channel busy time and retransmissions during a controlled multi-client transfer directly tests the desired behavior.

Incorrect Answers

ARP resolves IPv4 neighbors to MAC addresses within the local broadcast domain. That observation tests a different condition, not the required result.

VLAN tags identify individual logical Layer 2 networks on a shared trunk. That observation tests a different condition, not the required result.

Same-channel cells share contention opportunities even when SSIDs are identical. That observation tests a different condition, not the required result.

Question 231

Following a campus change for this issue—a network uses private DNS zones to locate management services—which result most directly verifies that the remedy works?

Compare planned demand, per-port allocation and system remaining budget.
Run management-VRF sourced ping and route lookup to the cloud endpoint.
Resolve a known management FQDN from the device's management network.
Trace the AP's IP assignment and management connection after boot.

Explanation

Correct Answer

Control-plane enrollment can fail when hostnames cannot resolve correctly. Resolve a known management FQDN from the device's management network directly tests the desired behavior.

Incorrect Answers

A shared PoE power budget can limit the number of fully powered endpoints. 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.

AP onboarding depends on working network bootstrap and a reachable management service. That observation tests a different condition, not the required result.

Question 232

During campus implementation, an RF survey shows an elevated noise floor across 2.4 GHz. What should the engineer configure or correct?

Adjust cell size, minimum basic rates and roaming policy carefully.
Check client capabilities before expecting 802.11ax-specific features.
Use spectrum analysis to identify non-Wi-Fi interferers.
Consolidate SSIDs when policy requirements permit.

Explanation

Correct Answer

Microwave, Bluetooth and industrial emitters can raise noise without being an 802.11 AP. The engineer should use spectrum analysis to identify non-Wi-Fi interferers.

Incorrect Answers

Excess cell reach and very low data rates can promote sticky clients. It is not a direct remedy for the condition described.

Legacy clients cannot use HE-only scheduling features. It is not a direct remedy for the condition described.

Each SSID adds beacon and management overhead to the channel. It is not a direct remedy for the condition described.

Question 233

A technician has applied this fix: Ensure a reachable IGMP querier exists in that VLAN. Which observation would provide the strongest acceptance evidence?

Capture LLDP-MED advertisements and check phone VLAN state.
Try permitted and denied management connections from test hosts.
Capture IGMP queries and monitor group expiration.
Check both peers' negotiated duplex and error counters.

Explanation

Correct Answer

IGMP group maintenance requires periodic membership queries. Capture IGMP queries and monitor group expiration directly tests the desired behavior.

Incorrect Answers

LLDP-MED can communicate voice VLAN and QoS settings to phones. That observation tests a different condition, not the required result.

Administrative access protection is distinct from normal endpoint forwarding. That observation tests a different condition, not the required result.

Duplex mismatch can create collisions and poor performance. That observation tests a different condition, not the required result.

Question 234

A network team reports the following condition: An AP's transmit power is far above handheld receive capability. Select the most appropriate response.

Use an appropriate 802.11k neighbor report policy.
Balance AP power with realistic client transmit limits.
Tune effective radiated power and separation using site survey measurements.
Review WLAN multicast delivery mode and airtime cost.

Explanation

Correct Answer

Downlink coverage does not ensure the return path from low-power clients. The engineer should balance AP power with realistic client transmit limits.

Incorrect Answers

Neighbor reports can reduce the amount of blind scanning needed. It is not a direct remedy for the condition described.

Cell overlap depends on EIRP, antenna pattern and building attenuation. It is not a direct remedy for the condition described.

Wireless multicast can use rates and buffering unlike wired unicast. It is not a direct remedy for the condition described.

Question 235

The campus team is closing a service ticket about this condition: A MAC-based printer moves to a different access switch but is assigned a generic user role. Which validation step is most relevant?

Authenticate a known-good certificate and inspect role attributes.
Connect a second unauthorized endpoint and verify it stays isolated.
Compare profiling result and effective role on both switches.
Capture EAPOL at the port and UDP RADIUS toward the server.

Explanation

Correct Answer

Device category and enforcement mapping must follow endpoint identity across locations. Compare profiling result and effective role on both switches directly tests the desired behavior.

Incorrect Answers

EAP-TLS validates certificate identity and central policy chooses the access role. That observation tests a different condition, not the required result.

Client-mode authenticates connected clients individually where supported. That observation tests a different condition, not the required result.

EAPOL client traffic still needs the authenticator to reach RADIUS. That observation tests a different condition, not the required result.

Question 236

After completing the planned work for this situation—a high-density AP deployment has good coverage but too many simultaneous clients on one radio—how should success be checked?

Compare channel maps and CCI before and after channel changes.
Measure concurrent client distribution and busy time per radio.
Disable the preferred uplink and check client traffic and AP management continuity.
Check negotiated TWT support and device wake intervals.

Explanation

Correct Answer

Capacity is constrained by shared airtime, not simply signal strength. Measure concurrent client distribution and busy time per radio directly tests the desired behavior.

Incorrect Answers

Overlapping 2.4 GHz cells contend and interfere on shared channels. That observation tests a different condition, not the required result.

AP resiliency requires compatible management and user VLAN reachability after switching links. That observation tests a different condition, not the required result.

TWT coordinates scheduled wake/sleep periods to reduce contention and energy use. That observation tests a different condition, not the required result.

Question 237

The engineer reports completing this change: Correlate logs, topology changes and historical telemetry around the failure time. Which verification should be included in the handover?

Trace one permitted and denied test flow against hit counters.
Align interface-event and client-failure timestamps.
Inspect optic diagnostics and both ends' link state.
Compare OSPF neighbor state and MTU.

Explanation

Correct Answer

End-state snapshots may miss transient faults. Align interface-event and client-failure timestamps directly tests the desired behavior.

Incorrect Answers

ACL ordering and attachment point determine real packet authorization. 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.

OSPF DBD exchange can be impeded by incompatible link parameters. That observation tests a different condition, not the required result.

Question 238

For an HPE Aruba Networking campus deployment, an IP phone is on the data VLAN because it never learned the voice VLAN. Which action best addresses it?

Inspect LLDP-MED voice policy and endpoint support.
Validate primary/secondary VLAN associations and port roles where supported.
Use the platform's supported management interface/VRF.
Check cabling, transceiver compatibility and physical-layer faults.

Explanation

Correct Answer

LLDP-MED can communicate voice VLAN and QoS settings to phones. The engineer should inspect LLDP-MED voice policy and endpoint support.

Incorrect Answers

Private VLAN constructs isolate hosts within a shared IP subnet. It is not a direct remedy for the condition described.

Dedicated management routing avoids mixing administration with production forwarding. It is not a direct remedy for the condition described.

Frame check errors usually indicate problems below the IP layer. It is not a direct remedy for the condition described.

Question 239

An AP has a backup Ethernet uplink but clients lose service whenever the preferred uplink fails. Which change most directly meets this campus requirement?

Confirm clients support 6 GHz and the selected Wi-Fi 6E/7 security profile.
Inspect channel airtime usage, co-channel interference and retry rates.
Consider narrower channels and a more suitable reuse plan.
Validate supported AP uplink failover and matching VLAN availability on the alternate port.

Explanation

Correct Answer

AP resiliency requires compatible management and user VLAN reachability after switching links. The engineer should validate supported AP uplink failover and matching VLAN availability on the alternate port.

Incorrect Answers

6 GHz discovery requires compatible client radio and security support. It is not a direct remedy for the condition described.

Strong signal alone does not guarantee available airtime. 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 240

Following a campus change for this issue—a switch's default administrative password is shared among technicians—which result most directly verifies that the remedy works?

Attempt traffic from an unexpected VLAN and inspect frame classification.
Verify PMF negotiated and controlled spoofed disconnect is rejected.
Try an allowed operation and a restricted admin operation.
Simulate RADIUS outage and observe the assigned critical role.

Explanation

Correct Answer

Individual accounts enable accountability and least-privilege authorization. Try an allowed operation and a restricted admin operation directly tests the desired behavior.

Incorrect Answers

Incorrect allowed/native VLAN settings weaken L2 segmentation. That observation tests a different condition, not the required result.

Protected management frames prevent unauthenticated robust management manipulation. That observation tests a different condition, not the required result.

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