HP HPE7-A01 Practice Test 31

Question 300

An EAP-TLS server uses a certificate with the wrong name. Which change most directly meets this campus requirement?

Correct server identity/SAN to match client trust expectations.
Use supported RADIUS CoA or reauthorization workflow.
Install the required trust anchor or replace the untrusted certificate.
Ensure endpoint profiling/group mapping is applied consistently.

Explanation

Correct Answer

Supplicants may reject a server even when its signing CA is trusted. The engineer should correct server identity/SAN to match client trust expectations.

Incorrect Answers

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

EAP-TLS succeeds only with a valid trusted certificate chain. It is not a direct remedy for the condition described.

Device category and enforcement mapping must follow endpoint identity across locations. It is not a direct remedy for the condition described.

Question 301

The campus team is closing a service ticket about this condition: An Aruba Central user needs repeatable read-only device queries. Which validation step is most relevant?

Check installed versus intended version after controlled reboot.
Issue a read-only request with a scoped credential and inspect response.
Compare sensor DNS/HTTP test results with an incident window.
Compare the audit diff with the device's active configuration.

Explanation

Correct Answer

APIs allow programmatic access while permissions control scope. Issue a read-only request with a scoped credential and inspect response directly tests the desired behavior.

Incorrect Answers

Version management requires appropriate platform images and maintenance windows. That observation tests a different condition, not the required result.

Synthetic user-experience probes reveal service reachability and performance. That observation tests a different condition, not the required result.

Configuration intent and installed running state must be compared. That observation tests a different condition, not the required result.

Question 302

The engineer reports completing this change: Record reproducible prechange coverage, throughput and error metrics. Which verification should be included in the handover?

Capture DSCP and inspect queue maps on the bottleneck switch.
Generate voice and bulk traffic and measure jitter/queue drops.
Repeat the same test plan and compare normalized metrics.
Compare AP channel maps, channel busy time and retries.

Explanation

Correct Answer

Optimization requires a measured baseline to distinguish improvement from noise. Repeat the same test plan and compare normalized metrics 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.

QoS scheduling helps latency-sensitive packets compete under load. 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 303

A technician has applied this fix: Correlate port-access session, device role and MAC table update. Which observation would provide the strongest acceptance evidence?

Follow RADIUS result, effective role and forwarding MAC table over time.
Send incrementing frame sizes and read giant/discard counters.
Inspect the VLAN's forwarding members and SVI up/down state.
Correlate event log timestamp with port status and offending traffic.

Explanation

Correct Answer

Dynamic access policy can change VLAN/role while a client reconnects. Follow RADIUS result, effective role and forwarding MAC table over time directly tests the desired behavior.

Incorrect Answers

Oversized frames can be dropped when intermediate L2 links have smaller MTU. That observation tests a different condition, not the required result.

An SVI may depend on its VLAN being operationally active. That observation tests a different condition, not the required result.

An automatic protection feature may be intentionally shutting the port. That observation tests a different condition, not the required result.

Question 304

For an HPE Aruba Networking campus deployment, a campus host is redirected by an ARP spoofing attempt. Which action best addresses it?

Use supported MACsec with authenticated keys and compatible peers.
Replace plaintext admin access with SSH/HTTPS and scoped management ACLs.
Enforce current posture result via RADIUS role/CoA policies.
Enable DAI or equivalent protection with trustworthy bindings.

Explanation

Correct Answer

Dynamic ARP inspection validates address/MAC claims on untrusted ports. The engineer should enable DAI or equivalent protection with trustworthy bindings.

Incorrect Answers

MACsec protects selected Ethernet frames at Layer 2. It is not a direct remedy for the condition described.

Secure administration requires both encryption and source restriction. It is not a direct remedy for the condition described.

Dynamic authorization must reflect changing endpoint trust. It is not a direct remedy for the condition described.

Question 305

After completing the planned work for this situation—a campus loses only one routed subnet after a link change—how should success be checked?

Use traceroute and hop-limit expiry to locate the oscillating path.
Capture hello packets and verify consistent timers.
Trace the route lookup for failing and healthy subnets.
Inspect received default and chosen route after policy evaluation.

Explanation

Correct Answer

A less-specific summary can mask an absent needed route. Trace the route lookup for failing and healthy subnets directly tests the desired behavior.

Incorrect Answers

Two mutually pointing next hops can form an L3 forwarding loop. That observation tests a different condition, not the required result.

Neighbor timer compatibility matters for OSPF adjacency formation. That observation tests a different condition, not the required result.

Route import policy can protect internal next-hop expectations. That observation tests a different condition, not the required result.

Question 306

An engineer is planning corrective work because a Central dashboard incorrectly groups APs from two buildings under one site. Which step should be prioritized?

Use Central device health, inventory and telemetry views.
Use the documented authenticated REST API and appropriate role.
Export a supported backup or checkpoint and record rollback steps.
Correct site assignments without assuming the configuration group is a site.

Explanation

Correct Answer

Groups primarily determine configuration; sites support physical/location reporting. The engineer should correct site assignments without assuming the configuration group is a site.

Incorrect Answers

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

APIs allow programmatic access while permissions control scope. It is not a direct remedy for the condition described.

Recovery requires a known-good configuration and compatible restore method. It is not a direct remedy for the condition described.

Question 307

The engineer reports completing this change: Reclassify or remark untrusted ingress traffic at the boundary. Which verification should be included in the handover?

Generate an authorized test login failure and confirm its log record.
Inject high-marked guest traffic and observe effective egress class.
Test permitted secure access and rejected plaintext or unauthorized access.
Inspect snooping binding table and blocked offer counters.

Explanation

Correct Answer

Untrusted clients can self-mark traffic to obtain an undeserved priority. Inject high-marked guest traffic and observe effective egress class directly tests the desired behavior.

Incorrect Answers

Audit evidence is necessary even when alert thresholds create noise. That observation tests a different condition, not the required result.

Secure administration requires both encryption and source restriction. That observation tests a different condition, not the required result.

DHCP snooping can block server responses on untrusted access links. That observation tests a different condition, not the required result.

Question 308

Following a campus change for this issue—a Wi-Fi client briefly loses service after moving between VLAN-dependent AP groups—which result most directly verifies that the remedy works?

Compare client IP, gateway and effective role before/after roam.
Disable the preferred uplink and check client traffic and AP management continuity.
Observe client capability and uplink channel utilization during small-packet traffic.
Track the dual-band client's selected radio after steering changes.

Explanation

Correct Answer

L3 or policy changes during roaming can interrupt sessions beyond RF association delay. Compare client IP, gateway and effective role before/after roam directly tests the desired behavior.

Incorrect Answers

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

OFDMA divides airtime into resource units for efficient multi-user scheduling. That observation tests a different condition, not the required result.

Steering affects association choices but cannot guarantee every client switches bands. That observation tests a different condition, not the required result.

Question 309

An engineer is planning corrective work because an edge uses two equal-cost routes but only one is installed. Which step should be prioritized?

Check platform ECMP settings and route eligibility.
Make user-facing OSPF interfaces passive while advertising the prefix.
Configure a static route with a reachable next hop in the correct VRF.
Check multicast routing and IGMP receiver state.

Explanation

Correct Answer

Multiple configured next hops do not guarantee equal-cost installation. The engineer should check platform ECMP settings and route eligibility.

Incorrect Answers

Passive OSPF suppresses adjacency exchange on the selected interface. It is not a direct remedy for the condition described.

Static forwarding requires the destination prefix and next-hop resolution. It is not a direct remedy for the condition described.

Multicast forwarding requires a forwarding tree and interested receivers. It is not a direct remedy for the condition described.

Question 310

During campus implementation, a VSX split could cause both core peers to forward incorrectly. What should the engineer configure or correct?

Keep healthy LAG members forwarding while removing the failed link.
Use an AP/switch design with supported wired failover and consistent VLAN policy.
Review ISL/keepalive health and split-brain protection design.
Verify supported conductor/standby election and management continuity.

Explanation

Correct Answer

Peer-state detection and the configured safeguards govern split failure response. The engineer should review ISL/keepalive health and split-brain protection design.

Incorrect Answers

LACP aggregation can survive individual member loss. It is not a direct remedy for the condition described.

Failover paths must preserve required management and client VLAN reachability. It is not a direct remedy for the condition described.

Stack control-plane failover is distinct from individual data-link forwarding. It is not a direct remedy for the condition described.
