HP HPE7-A01 Practice Test 29

Question 280

The engineer reports completing this change: Correlate roam events, authentication timing and application jitter. Which verification should be included in the handover?

Compare RADIUS/supplicant TLS errors for failing clients.
Capture the roam time line and RTP loss at each stage.
Inspect AP power limitations and switch allocated wattage.
Align interface-event and client-failure timestamps.

Explanation

Correct Answer

Fast RF association and data-plane continuity are different measures. Capture the roam time line and RTP loss at each stage directly tests the desired behavior.

Incorrect Answers

Certificate validation occurs after the client discovers the SSID. That observation tests a different condition, not the required result.

Insufficient PoE can cause reduced AP functionality while link remains up. That observation tests a different condition, not the required result.

End-state snapshots may miss transient faults. That observation tests a different condition, not the required result.

Question 281

A network team reports the following condition: A user signs into a guest portal but retains a pre-authentication role. Select the most appropriate response.

Ensure endpoint profiling/group mapping is applied consistently.
Ensure certificate revocation checking is enforced where applicable.
Complete the authenticated role transition and captive-portal authorization.
Adjust a wired printer access-port VLAN without examining the guest portal role transition.

Explanation

Correct Answer

Portal success requires enforcement state to change before normal internet traffic. The engineer should complete the authenticated role transition and captive-portal authorization.

Incorrect Answers

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

A valid-looking certificate may no longer be authorized after revocation. It is not a direct remedy for the condition described.

A wired printer VLAN change does not update a guest user session that remains in its captive-portal preauthentication role.

Question 282

The campus team is closing a service ticket about this condition: A field technician needs to discover what is connected to each access-switch port. Which validation step is most relevant?

Capture VLAN tags across the trunk and verify endpoint membership.
Show overlapping prefixes in separate VRF route tables without leakage.
Compare neighbor chassis/port IDs with the patching schedule.
Compare egress queue drops and utilization during a load test.

Explanation

Correct Answer

LLDP advertises directly connected device identity and capabilities. Compare neighbor chassis/port IDs with the patching schedule directly tests the desired behavior.

Incorrect Answers

VLAN classification on ingress determines Layer 2 forwarding and segmentation. That observation tests a different condition, not the required result.

VRFs provide separate Layer 3 routing contexts on one system. That observation tests a different condition, not the required result.

Output drops can arise from queue pressure even without physical corruption. That observation tests a different condition, not the required result.

Question 283

Following a campus change for this issue—a campus access port should authenticate devices before granting production access—which result most directly verifies that the remedy works?

Inspect snooping binding table and blocked offer counters.
Test valid, expired and untrusted certificate outcomes.
Compare effective role and permitted flows for approved and denied clients.
Observe secure-channel negotiation and protected frame counters.

Explanation

Correct Answer

Port access control restricts network membership to authenticated endpoints. Compare effective role and permitted flows for approved and denied clients directly tests the desired behavior.

Incorrect Answers

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

EAP-TLS authenticates endpoints using public-key certificates. That observation tests a different condition, not the required result.

MACsec protects selected Ethernet frames at Layer 2. That observation tests a different condition, not the required result.

Question 284

Multiple switches report the same default-gateway MAC flapping between ports. Which change most directly meets this campus requirement?

Align the interface address and prefix with the reachable management gateway.
Verify the intended gateway virtualization design and L2 loop condition.
Assign them to the appropriate Central group or template scope.
Negotiate or explicitly align supported speed and duplex settings.

Explanation

Correct Answer

Unplanned gateway MAC movement can reflect duplicated gateway identity or loops. The engineer should verify the intended gateway virtualization design and L2 loop condition.

Incorrect Answers

Incorrect address/prefix selection prevents ordinary management routing. It is not a direct remedy for the condition described.

A management group determines the policy and configuration applied to its devices. It is not a direct remedy for the condition described.

Link establishment depends on mutually supported PHY settings. It is not a direct remedy for the condition described.

Question 285

Following a campus change for this issue—a routed SVI is configured but its VLAN has no active member ports—which result most directly verifies that the remedy works?

Offer DHCP from trusted and untrusted sides and inspect counters.
Capture LACP PDUs and verify both interfaces are in one bundle.
Inspect the VLAN's forwarding members and SVI up/down state.
Verify root bridge ID and root port selections across the VLAN instances.

Explanation

Correct Answer

An SVI may depend on its VLAN being operationally active. Inspect the VLAN's forwarding members and SVI up/down state directly tests the desired behavior.

Incorrect Answers

DHCP snooping blocks unauthorized server replies on untrusted ports. That observation tests a different condition, not the required result.

Active mode initiates LACP negotiations that passive mode answers. That observation tests a different condition, not the required result.

Spanning-tree root selection must reflect the planned campus topology. That observation tests a different condition, not the required result.

Question 286

During campus implementation, a new AP powers on but cannot join its intended management platform. What should the engineer configure or correct?

Validate DHCP addressing, DNS and the documented AP discovery path.
Align the LACP actor/partner mode and member compatibility.
Investigate lease, gateway and address conflict information.
Align the interface address and prefix with the reachable management gateway.

Explanation

Correct Answer

AP onboarding depends on working network bootstrap and a reachable management service. The engineer should validate DHCP addressing, DNS and the documented AP discovery path.

Incorrect Answers

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

Duplicate management addresses or unstable DHCP assignments break control-plane reachability. It is not a direct remedy for the condition described.

Incorrect address/prefix selection prevents ordinary management routing. It is not a direct remedy for the condition described.

Question 287

An engineer is planning corrective work because an IP phone and workstation share one wall jack. Which step should be prioritized?

Configure reachable DNS resolvers with the required records.
Confirm the AP VLAN reaches a DHCP server or relay.
Provide a supported voice VLAN and separate data-network authorization.
Provide reachable, permitted NTP service and correct time-zone display.

Explanation

Correct Answer

Voice and data traffic can share a port while retaining distinct VLAN and policy treatment. The engineer should provide a supported voice VLAN and separate data-network authorization.

Incorrect Answers

Control-plane enrollment can fail when hostnames cannot resolve correctly. It is not a direct remedy for the condition described.

Power-up and Layer 2 association alone do not ensure IP address assignment. It is not a direct remedy for the condition described.

Accurate time is needed for logging and certificate validation. It is not a direct remedy for the condition described.

Question 288

The campus team is closing a service ticket about this condition: A BGP speaker leaks management prefixes into a provider session. Which validation step is most relevant?

Send traffic to the blackhole prefix and check drop behavior.
Trace the route lookup for failing and healthy subnets.
Fail one transit and observe TCP and BGP session continuity.
Compare intended and actual advertised prefix lists.

Explanation

Correct Answer

Outbound routing policies control which local routes are advertised. Compare intended and actual advertised prefix lists 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.

A less-specific summary can mask an absent needed route. That observation tests a different condition, not the required result.

Loopback sessions survive individual link changes when routed connectivity remains. That observation tests a different condition, not the required result.

Question 289

The engineer reports completing this change: Use supported port mirroring to a capture destination. Which verification should be included in the handover?

Capture mirrored packets and validate the intended source/direction.
Attempt a supported lab configuration and review feature conflict status.
Verify NTP synchronization and correlate a known test event.
Check installed versus intended version after controlled reboot.

Explanation

Correct Answer

Mirroring copies selected interface traffic for protocol analysis. Capture mirrored packets and validate the intended source/direction directly tests the desired behavior.

Incorrect Answers

Some platform/release combinations limit simultaneous capture features. That observation tests a different condition, not the required result.

Cross-device troubleshooting depends on aligned timestamps and measurements. That observation tests a different condition, not the required result.

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

Question 290

For an HPE Aruba Networking campus deployment, a switch NAE agent cannot read a protected CLI command after AAA changes. Which action best addresses it?

Compare mirrored packet captures from the configured source and destination ports.
Use supported sFlow telemetry instead of full packet mirroring.
Correct site assignments without assuming the configuration group is a site.
Verify NAE command authorization under the intended AAA policy.

Explanation

Correct Answer

NAE operations may be constrained by command authorization. The engineer should verify NAE command authorization under the intended AAA policy.

Incorrect Answers

Port mirroring supports packet inspection; it cannot resolve NAE command authorization failures following an AAA policy change.

sFlow samples packets and interface counters for flow visibility. It is not a direct remedy for the condition described.

Groups primarily determine configuration; sites support physical/location reporting. It is not a direct remedy for the condition described.
