HP HPE7-A01 Practice Test 42

Question 410

Following a campus change for this issue—new access switches require repeatable configuration at dozens of sites—which result most directly verifies that the remedy works?

Resolve a known management FQDN from the device's management network.
Compare switch LLDP neighbor detail and the phone's advertised capabilities.
Inspect topology and simulated single-link resilience during maintenance.
Compare intended group assignment with the applied configuration audit.

Explanation

Correct Answer

A management group determines the policy and configuration applied to its devices. Compare intended group assignment with the applied configuration audit directly tests the desired behavior.

Incorrect Answers

Control-plane enrollment can fail when hostnames cannot resolve correctly. 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.

A resilient stack topology avoids relying on one physical intermember path. That observation tests a different condition, not the required result.

Question 411

During campus implementation, a redundancy design uses LACP members through one failed access port. What should the engineer configure or correct?

Establish an eligible backup route and failure detection method.
Ensure spanning tree or loop protection blocks the redundant path.
Keep healthy LAG members forwarding while removing the failed link.
Validate the supported local forwarding behavior of the deployed solution.

Explanation

Correct Answer

LACP aggregation can survive individual member loss. The engineer should keep healthy LAG members forwarding while removing the failed link.

Incorrect Answers

Redundancy requires more than an unused physical interface. It is not a direct remedy for the condition described.

Loop prevention protects bridged domains from uncontrolled circulation. It is not a direct remedy for the condition described.

Management-plane loss should be evaluated separately from the user forwarding path. It is not a direct remedy for the condition described.

Question 412

A DHCP service becomes unreachable after one site node fails. Which change most directly meets this campus requirement?

Check the inter-switch link connectivity and VSX state.
Validate the supported local forwarding behavior of the deployed solution.
Provide redundant reachable DHCP servers or relay destinations.
Design a supported ring or alternate stack-link topology.

Explanation

Correct Answer

DHCP address assignment should not depend on one failed server. The engineer should provide redundant reachable DHCP servers or relay destinations.

Incorrect Answers

The VSX inter-switch link carries peer coordination and state traffic. It is not a direct remedy for the condition described.

Management-plane loss should be evaluated separately from the user forwarding path. It is not a direct remedy for the condition described.

Redundant stacking paths can preserve member connectivity after one link fails. It is not a direct remedy for the condition described.

Question 413

Following a campus change for this issue—an AP has excellent RSSI but poor SNR near heavy machinery—which result most directly verifies that the remedy works?

Compare queue depth and latency during a backup transfer.
Measure noise floor during machinery operation and after mitigation.
Generate voice and bulk traffic and measure jitter/queue drops.
Measure association RSSI at roam and compare before/after tuning.

Explanation

Correct Answer

SNR combines received signal strength with background noise. Measure noise floor during machinery operation and after mitigation directly tests the desired behavior.

Incorrect Answers

Long egress queues create delay and jitter under sustained overload. 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.

Excess power can delay client roaming despite good RSSI. That observation tests a different condition, not the required result.

Question 414

The campus team is closing a service ticket about this condition: A client supports both 2.4 and 5 GHz but remains on noisy 2.4 GHz. Which validation step is most relevant?

Compare BSS color assignments and airtime/retry behavior across cells.
Compare pre-login and post-login client-role traffic captures.
Track the dual-band client's selected radio after steering changes.
Record channel utilization and per-client retries at peak attendance.

Explanation

Correct Answer

Steering affects association choices but cannot guarantee every client switches bands. Track the dual-band client's selected radio after steering changes directly tests the desired behavior.

Incorrect Answers

BSS coloring can help distinguish overlapping transmissions under supported spatial reuse. That observation tests a different condition, not the required result.

Portal authentication must result in a usable authorized forwarding role. That observation tests a different condition, not the required result.

Strong signal alone does not guarantee available airtime. That observation tests a different condition, not the required result.

Question 415

During campus implementation, a multicast IPTV design sends data to networks without subscribed listeners. What should the engineer configure or correct?

Set appropriate OSPF interface priority where supported.
Correct inconsistent static/default routes or route redistribution.
Verify longest-prefix route selection instead of relying on next-hop metric alone.
Check multicast routing and IGMP receiver state.

Explanation

Correct Answer

Multicast forwarding requires a forwarding tree and interested receivers. The engineer should check multicast routing and IGMP receiver state.

Incorrect Answers

DR election considers priority before router-ID tiebreaking. It is not a direct remedy for the condition described.

Two mutually pointing next hops can form an L3 forwarding loop. It is not a direct remedy for the condition described.

More-specific prefixes normally override less-specific matches in route lookup. It is not a direct remedy for the condition described.

Question 416

The engineer reports completing this change: Ensure certificate revocation checking is enforced where applicable. Which verification should be included in the handover?

Attempt authentication with a revoked test certificate.
Authenticate a known-good certificate and inspect role attributes.
Connect an approved and unregistered printer MAC and compare roles.
Inspect identity result, ClearPass enforcement policy and controller role.

Explanation

Correct Answer

A valid-looking certificate may no longer be authorized after revocation. Attempt authentication with a revoked test certificate 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.

MAB can accommodate legacy devices but offers weaker identity assurance. That observation tests a different condition, not the required result.

A successful identity check does not automatically grant every role. That observation tests a different condition, not the required result.

Question 417

During campus implementation, an AP behind a switch is powered but gets no DHCP response. What should the engineer configure or correct?

Confirm the AP VLAN reaches a DHCP server or relay.
Align supported member images and the stack compatibility requirements.
Configure or validate its next-hop reachability and routing policy.
Budget total power draw before enabling all powered ports.

Explanation

Correct Answer

Power-up and Layer 2 association alone do not ensure IP address assignment. The engineer should confirm the AP VLAN reaches a DHCP server or relay.

Incorrect Answers

Stack membership commonly requires compatible software and platform capabilities. It is not a direct remedy for the condition described.

Physical carrier state is distinct from an installed usable route. It is not a direct remedy for the condition described.

A shared PoE power budget can limit the number of fully powered endpoints. It is not a direct remedy for the condition described.

Question 418

Following a campus change for this issue—a client knows a local IPv4 destination but cannot locate its MAC address—which result most directly verifies that the remedy works?

Capture both EAPOL and RADIUS traffic on the appropriate interfaces.
Capture the association exchange and confirm the client reaches associated state.
Compare observed beacon intervals and channel airtime usage.
Review ARP and MAC tables and capture ARP exchange for the target.

Explanation

Correct Answer

ARP resolves IPv4 neighbors to MAC addresses within the local broadcast domain. Review ARP and MAC tables and capture ARP exchange for the target directly tests the desired behavior.

Incorrect Answers

EAPOL is used at the endpoint edge while the authenticator relays authentication over RADIUS. That observation tests a different condition, not the required result.

Wi-Fi management frames establish the radio connection before IP-layer onboarding. That observation tests a different condition, not the required result.

Beacons and management frames consume radio airtime independently of application payload. That observation tests a different condition, not the required result.

Question 419

A network team reports the following condition: A data uplink suffers large queues during backup hours. Select the most appropriate response.

Optimize multicast delivery and eligible wireless rates.
Apply suitable shaping or policing based on desired behavior.
Inspect the client transmit power and return-path quality.
Tune scheduling, shaping and available path capacity.

Explanation

Correct Answer

Long egress queues create delay and jitter under sustained overload. The engineer should tune scheduling, shaping and available path capacity.

Incorrect Answers

Multicast transmissions can consume disproportionate shared airtime. 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.

AP downlink power may exceed handheld uplink capability. It is not a direct remedy for the condition described.

Question 420

During campus implementation, an endpoint is reachable from one switch but not another in the same VLAN. What should the engineer configure or correct?

Diff the current state against the last known-good configuration.
Check TCP port 179, source address and remote AS settings.
Inspect EAP/TLS trust and expiration before changing WLAN channels.
Inspect MAC table learning and potential port-security blocking.

Explanation

Correct Answer

Layer 2 forwarding depends on learned destination MAC and permitted ports. The engineer should inspect MAC table learning and potential port-security blocking.

Incorrect Answers

Change correlation narrows likely causes without assuming every recent edit is wrong. It is not a direct remedy for the condition described.

IP reachability alone does not establish BGP session negotiation. It is not a direct remedy for the condition described.

Certificate validation occurs after the client discovers the SSID. It is not a direct remedy for the condition described.
