HP HPE7-A01 Practice Test 26

Question 250

After completing the planned work for this situation—an AP uses a tagged management VLAN but the switch sends it untagged—how should success be checked?

Power on a representative unit and trace automatic policy assignment.
Resolve a known management FQDN from the device's management network.
Capture the first management exchange and inspect uplink VLAN settings.
Inspect transceiver diagnostics and both ends' interface state.

Explanation

Correct Answer

AP management requires consistent tagged versus untagged treatment. Capture the first management exchange and inspect uplink VLAN settings directly tests the desired behavior.

Incorrect Answers

Preprovisioning moves repeatable configuration into central management. That observation tests a different condition, not the required result.

Control-plane enrollment can fail when hostnames cannot resolve correctly. That observation tests a different condition, not the required result.

Physical link-up requires matching media and supported transceiver properties. That observation tests a different condition, not the required result.

Question 251

A technician has applied this fix: Negotiate or explicitly align supported speed and duplex settings. Which observation would provide the strongest acceptance evidence?

Power on a representative unit and trace automatic policy assignment.
Inspect negotiated media speed and both sides' interface counters.
Check allowed VLANs and the operational VLAN table at both ends.
Compare switch LLDP neighbor detail and the phone's advertised capabilities.

Explanation

Correct Answer

Link establishment depends on mutually supported PHY settings. Inspect negotiated media speed and both sides' interface counters directly tests the desired behavior.

Incorrect Answers

Preprovisioning moves repeatable configuration into central management. That observation tests a different condition, not the required result.

Trunk VLAN filtering can silently drop an otherwise correctly tagged subnet. That observation tests a different condition, not the required result.

LLDP-MED exchanges device and voice-network capability information. That observation tests a different condition, not the required result.

Question 252

For an HPE Aruba Networking campus deployment, a campus file-transfer application requires encryption over a shared segment. Which action best addresses it?

Enforce supported port-security violation behavior.
Map authenticated identities to suitable Aruba user roles.
Use supported higher-layer TLS or MACsec where appropriate.
Refine the guest policy with explicit application and destination constraints.

Explanation

Correct Answer

Encryption choice depends on Layer 2 versus application-layer trust boundaries. The engineer should use supported higher-layer TLS or MACsec where appropriate.

Incorrect Answers

Port security prevents arbitrary new MAC addresses from gaining access. It is not a direct remedy for the condition described.

Roles can express differentiated access independent of separate SSID proliferation. 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.

Question 253

During campus implementation, many SSIDs are configured on the same radio in a dense floor. What should the engineer configure or correct?

Consolidate SSIDs when policy requirements permit.
Review band steering and client preference while preserving compatibility.
Use supported BSS transition management with a suitable candidate list.
Use scoped certificate-level controls without unauthorized TLS payload inspection.

Explanation

Correct Answer

Each SSID adds beacon and management overhead to the channel. The engineer should consolidate SSIDs when policy requirements permit.

Incorrect Answers

Steering affects association choices but cannot guarantee every client switches bands. It is not a direct remedy for the condition described.

802.11v can suggest a better BSS, but the client decides whether to comply. It is not a direct remedy for the condition described.

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

Question 254

An engineer is planning corrective work because a multicast video WLAN degrades when there are many viewers. Which step should be prioritized?

Consider supported airtime fairness and data-rate policy.
Optimize multicast delivery and eligible wireless rates.
Consolidate SSIDs when authorization roles can differentiate users.
Record reproducible prechange coverage, throughput and error metrics.

Explanation

Correct Answer

Multicast transmissions can consume disproportionate shared airtime. The engineer should optimize multicast delivery and eligible wireless rates.

Incorrect Answers

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

More SSIDs increase beacon/management overhead. It is not a direct remedy for the condition described.

Optimization requires a measured baseline to distinguish improvement from noise. It is not a direct remedy for the condition described.

Question 255

The engineer reports completing this change: Optimize multicast delivery and eligible wireless rates. Which verification should be included in the handover?

Repeat the same test plan and compare normalized metrics.
Compare per-class airtime occupancy and application quality.
Measure beacon airtime and capacity with fewer SSIDs.
Measure multicast loss and radio airtime during stream replication.

Explanation

Correct Answer

Multicast transmissions can consume disproportionate shared airtime. Measure multicast loss and radio airtime during stream replication directly tests the desired behavior.

Incorrect Answers

Optimization requires a measured baseline to distinguish improvement from noise. That observation tests a different condition, not the required result.

Equal byte throughput is not the same as equal shared radio airtime. That observation tests a different condition, not the required result.

More SSIDs increase beacon/management overhead. That observation tests a different condition, not the required result.

Question 256

A technician has applied this fix: Use a surveyed RF plan or supported AirMatch dynamic channel assignment. Which observation would provide the strongest acceptance evidence?

Inspect neighbor-report responses during a controlled roam.
Capture DHCP packets after the successful association event.
Compare spectrum occupancy with AP channel utilization.
Compare channel changes and neighboring channel utilization after optimization.

Explanation

Correct Answer

Automatic RF optimization can adapt channel assignment to observed neighbors. Compare channel changes and neighboring channel utilization after optimization directly tests the desired behavior.

Incorrect Answers

Neighbor reports can reduce the amount of blind scanning needed. That observation tests a different condition, not the required result.

Successful association does not guarantee an IPv4 address. That observation tests a different condition, not the required result.

Microwave, Bluetooth and industrial emitters can raise noise without being an 802.11 AP. That observation tests a different condition, not the required result.

Question 257

A network team reports the following condition: A client receives high RSSI but its uplink stalls. Select the most appropriate response.

Re-mark untrusted traffic at the first managed boundary.
Inspect the client transmit power and return-path quality.
Record reproducible prechange coverage, throughput and error metrics.
Check negotiated HE capability and scheduler/radio utilization.

Explanation

Correct Answer

AP downlink power may exceed handheld uplink capability. The engineer should inspect the client transmit power and return-path quality.

Incorrect Answers

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

Optimization requires a measured baseline to distinguish improvement from noise. It is not a direct remedy for the condition described.

OFDMA benefits depend on both AP and client support and actual traffic mix. It is not a direct remedy for the condition described.

Question 258

The engineer reports completing this change: Use supported BFD where it is interoperable with the routing protocol. Which verification should be included in the handover?

Simulate controlled keepalive or ISL loss and review forwarded traffic.
Verify VSX peer health and downstream LAG member distribution.
Disable one AP and measure surviving signal and reassociation.
Measure fault detection and route withdrawal during an outage pilot.

Explanation

Correct Answer

BFD provides fast liveliness information separate from normal route timers. Measure fault detection and route withdrawal during an outage pilot directly tests the desired behavior.

Incorrect Answers

Peer-state detection and the configured safeguards govern split failure response. That observation tests a different condition, not the required result.

VSX coordinates two switches to provide multi-chassis LAG forwarding. That observation tests a different condition, not the required result.

Redundant coverage is a radio design concern, not only switch redundancy. That observation tests a different condition, not the required result.

Question 259

Verify edge state and response when a BPDU is received.
Compare per-member LACP state and active aggregate capacity.
Inject a superior BPDU in a lab and inspect guard state.

Explanation

Correct Answer

All participating LAG members must negotiate compatible operation. Compare per-member LACP state and active aggregate capacity directly tests the desired behavior.

Incorrect Answers

Dynamic ARP inspection can reject ARP packets inconsistent with trusted bindings. 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.

Root guard prevents an unplanned switch from taking over the root position. That observation tests a different condition, not the required result.

Question 260

During campus implementation, a wireless network uses multiple ESSIDs for user classes with distinct policy needs. What should the engineer configure or correct?

Rebalance clients across eligible APs and assess airtime fairness.
Check client and AP capability and actual MU transmission support.
Adjust AP placement and validated transmit-power design after a survey.
Prefer role-based policy where it reduces unnecessary SSID proliferation.

Explanation

Correct Answer

Distinct policy does not always require a new beaconing SSID. The engineer should prefer role-based policy where it reduces unnecessary SSID proliferation.

Incorrect Answers

Capacity is constrained by shared airtime, not simply signal strength. 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.
