HP HPE7-A01 Practice Test 46

Question 450

The engineer reports completing this change: Consider supported airtime fairness and data-rate policy. Which verification should be included in the handover?

Compare per-class airtime occupancy and application quality.
Measure association RSSI at roam and compare before/after tuning.
Track per-station airtime and edge connectivity before/after adjustment.
Compare AP channel maps, channel busy time and retries.

Explanation

Correct Answer

Equal byte throughput is not the same as equal shared radio airtime. Compare per-class airtime occupancy and application quality directly tests the desired behavior.

Incorrect Answers

Excess power can delay client roaming despite good RSSI. 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.

Co-channel interference causes shared airtime contention. That observation tests a different condition, not the required result.

Question 451

A network wants to use MAC authentication only when 802.1X is unavailable. Which change most directly meets this campus requirement?

Map ClearPass enforcement policy output to a device-supported role.
Use supported RADIUS CoA or reauthorization workflow.
Set a narrowly scoped critical/backup authorization role.
Configure an intended 802.1X-to-MAC fallback order.

Explanation

Correct Answer

Auth-method priority avoids bypassing strong identities prematurely. The engineer should configure an intended 802.1X-to-MAC fallback order.

Incorrect Answers

Identity validation must be followed by explicit authorization attributes. It is not a direct remedy for the condition described.

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

A RADIUS outage should not imply blanket production access. It is not a direct remedy for the condition described.

Question 452

For an HPE Aruba Networking campus deployment, a building has many adjacent APs with identical high EIRP. Which action best addresses it?

Prefer appropriately designed 5 GHz service where clients support it.
Rebalance clients across eligible APs and assess airtime fairness.
Verify roaming VLAN continuity and required mobility anchoring.
Tune effective radiated power and separation using site survey measurements.

Explanation

Correct Answer

Cell overlap depends on EIRP, antenna pattern and building attenuation. The engineer should tune effective radiated power and separation using site survey measurements.

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.

Capacity is constrained by shared airtime, not simply signal strength. It is not a direct remedy for the condition described.

L3 or policy changes during roaming can interrupt sessions beyond RF association delay. It is not a direct remedy for the condition described.

Question 453

An engineer is planning corrective work because a campus needs to compare optimization changes against an objective baseline. Which step should be prioritized?

Correct the DSCP-to-local-queue mapping and trust boundary.
Record reproducible prechange coverage, throughput and error metrics.
Review channel reuse and power plan using a measured survey.
Classify and prioritize the voice traffic in the appropriate egress queues.

Explanation

Correct Answer

Optimization requires a measured baseline to distinguish improvement from noise. The engineer should record reproducible prechange coverage, throughput and error metrics.

Incorrect Answers

Classification and queue scheduling both matter for end-to-end QoS. It is not a direct remedy for the condition described.

Co-channel interference causes shared airtime contention. 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 454

Following a campus change for this issue—oSPF neighbors use unequal hello and dead intervals—which result most directly verifies that the remedy works?

Compare OSPF cost and active next-hop choice before/after change.
Inspect area type and database LSA scope.
Disconnect a test link and measure neighbor/route withdrawal time.
Capture hello packets and verify consistent timers.

Explanation

Correct Answer

Neighbor timer compatibility matters for OSPF adjacency formation. Capture hello packets and verify consistent timers directly tests the desired behavior.

Incorrect Answers

OSPF SPF uses accumulated interface metrics for path selection. That observation tests a different condition, not the required result.

Stub-area properties constrain external route advertisement. That observation tests a different condition, not the required result.

BFD can drive rapid protocol fault detection independent of standard hello timers. That observation tests a different condition, not the required result.

Question 455

Following a campus change for this issue—an Aruba Central group configuration differs from actual device state—which result most directly verifies that the remedy works?

Compare sampled flow exports with port utilization counters.
Trigger the condition and inspect agent status and event output.
Compare the audit diff with the device's active configuration.
Compare event volume and real fault visibility after tuning.

Explanation

Correct Answer

Configuration intent and installed running state must be compared. Compare the audit diff with the device's active configuration directly tests the desired behavior.

Incorrect Answers

sFlow samples packets and interface counters for flow visibility. That observation tests a different condition, not the required result.

Network Analytics Engine agents can monitor specified switch conditions. That observation tests a different condition, not the required result.

Alert policy can be refined without losing underlying monitoring data. That observation tests a different condition, not the required result.

Question 456

A copper uplink shows increasing FCS and CRC errors. Which change most directly meets this campus requirement?

Correct the 802.1Q tagging and native VLAN expectation.
Trace trust boundaries and DSCP-to-queue mappings.
Correlate port-access session, device role and MAC table update.
Check cabling, transceiver compatibility and physical-layer faults.

Explanation

Correct Answer

Frame check errors usually indicate problems below the IP layer. The engineer should check cabling, transceiver compatibility and physical-layer faults.

Incorrect Answers

VLAN classification on ingress determines Layer 2 forwarding and segmentation. It is not a direct remedy for the condition described.

Marking must remain trusted through every intended QoS enforcement point. It is not a direct remedy for the condition described.

Dynamic access policy can change VLAN/role while a client reconnects. It is not a direct remedy for the condition described.

Question 457

The engineer reports completing this change: Evaluate supported ClientMatch/steering and client signal thresholds. Which verification should be included in the handover?

Compare candidate AP signal and steering event logs.
Compare channel changes and neighboring channel utilization after optimization.
Compare IP-literal connectivity with hostname resolution.
Compare management-frame airtime and edge coverage after a cautious rate change.

Explanation

Correct Answer

Client-steering features encourage better associations but cannot override all client behavior. Compare candidate AP signal and steering event logs directly tests the desired behavior.

Incorrect Answers

Automatic RF optimization can adapt channel assignment to observed neighbors. That observation tests a different condition, not the required result.

DNS failure can appear as WLAN failure despite correct radio and IP connectivity. That observation tests a different condition, not the required result.

Very low basic rates consume disproportionate airtime. That observation tests a different condition, not the required result.

Question 458

For an HPE Aruba Networking campus deployment, a voice workload shows jitter bursts when egress utilization is near 100 percent. Which action best addresses it?

Measure end-to-end bottleneck, TCP window and path loss rather than only switch port speed.
Consider 802.11r/k/v support and authentication-path tuning.
Reserve suitable queue priority and reduce oversubscription.
Apply suitable shaping or policing based on desired behavior.

Explanation

Correct Answer

Full link saturation exposes serialization and queuing delays. The engineer should reserve suitable queue priority and reduce oversubscription.

Incorrect Answers

Wide-area throughput is constrained by latency, loss and congestion. It is not a direct remedy for the condition described.

Roaming performance depends on scan, authentication and mobility handling. It is not a direct remedy for the condition described.

Shaping buffers over-rate traffic while policing can drop or remark it. It is not a direct remedy for the condition described.

Question 459

A technician has applied this fix: Integrate supported BFD on the relevant routed interfaces. Which observation would provide the strongest acceptance evidence?

Send traffic to the blackhole prefix and check drop behavior.
Verify TCP session state and neighbor source/destination.
Send allowed and denied test prefixes and inspect Adj-RIB-In.
Disconnect a test link and measure neighbor/route withdrawal time.

Explanation

Correct Answer

BFD can drive rapid protocol fault detection independent of standard hello timers. Disconnect a test link and measure neighbor/route withdrawal time directly tests the desired behavior.

Incorrect Answers

Null-route forwarding disposes packets without a normal next hop. That observation tests a different condition, not the required result.

BGP uses a TCP session and requires reachable configured neighbors. That observation tests a different condition, not the required result.

Inbound filtering controls which neighbor routes are accepted. That observation tests a different condition, not the required result.

Question 460

The engineer reports completing this change: Ensure area border routing is planned and configured correctly. Which verification should be included in the handover?

Advertise a client route and verify another client learns it.
Check intra-area and inter-area routes on each side.
Inject approved and denied test routes and examine propagated LSAs.
Verify the expected NSSA route and translated advertisement.

Explanation

Correct Answer

An ABR connects area 0 with additional OSPF areas. Check intra-area and inter-area routes on each side directly tests the desired behavior.

Incorrect Answers

Route reflection reduces the iBGP full-mesh requirement. That observation tests a different condition, not the required result.

Unfiltered redistribution can advertise unintended internal routes. That observation tests a different condition, not the required result.

NSSA permits controlled local external redistribution in a stub-like area. That observation tests a different condition, not the required result.
