HP HPE7-A08 Practice Test 46

Question 450

After implementing the approved change — Restore matching LACP partner mode and consistent member policy — for this scenario: An aggregated uplink loses half its capacity after a peer switch update. Which observed result BEST verifies the outcome?

All essential services return before a narrow revised change is retried
Both members join the intended aggregator and traffic distribution returns
Phones regain their voice VLAN and ordinary VLANs remain unchanged
The link becomes stable with acceptable receive power and error rate

Explanation

Correct Answer

Both members join the intended aggregator and traffic distribution returns. This is the observable acceptance evidence for the decision to restore matching LACP partner mode and consistent member policy. It demonstrates the principle that lACP negotiation and bundle settings must match across peers.

Incorrect Answers

This verification choice fits a different situation: A new switch configuration destabilizes many services after change approval. It does not resolve the stated failure mode. For this case, the decisive verification choice is to both members join the intended aggregator and traffic distribution returns.

This verification choice fits a different situation: A recent trunk edit accidentally removed a production voice VLAN. It does not resolve the stated failure mode. For this case, the decisive verification choice is to both members join the intended aggregator and traffic distribution returns.

This verification choice fits a different situation: An uplink stops after a maintenance crew replaces a single transceiver. It does not resolve the stated failure mode. For this case, the decisive verification choice is to both members join the intended aggregator and traffic distribution returns.

Question 451

An HPE Aruba Networking design review examines: An aggregated uplink loses half its capacity after a peer switch update. Which technical principle BEST explains the required approach?

Optical module compatibility must match port and fiber constraints
Configuration recovery prioritizes service restoration over untested guesses
Gateway redundancy depends on consistent virtual group identity and communication
LACP negotiation and bundle settings must match across peers

Explanation

Correct Answer

LACP negotiation and bundle settings must match across peers. The case therefore calls for this specifically controlled action: restore matching LACP partner mode and consistent member policy. The acceptance evidence is that both members join the intended aggregator and traffic distribution returns.

Incorrect Answers

Question 452

A risk review for the following wired-network case asks what should be avoided: An aggregated uplink loses half its capacity after a peer switch update. Which assumption creates the GREATEST implementation risk?

Redistributing every route as a substitute for fixing peer area mismatch
Converting one side to a static bundle while the other expects LACP
Power-cycling every campus device without checking stack member identity
Replacing whole switch configuration when one allowed-VLAN list is wrong

Explanation

Correct Answer

Converting one side to a static bundle while the other expects LACP. That shortcut fails because lACP negotiation and bundle settings must match across peers. Instead, the appropriate approach is to restore matching LACP partner mode and consistent member policy.

Incorrect Answers

Question 453

Before changing switch configuration, an engineer investigates: An aggregated uplink loses half its capacity after a peer switch update. Which FIRST check is most useful for isolating the cause?

Inspect RPF interface, PIM state and routing changes
Review change diff, checkpoint availability and current fault timeline
Inspect RADIUS response attributes and switch role mapping
Inspect LACP negotiation state and physical member counters

Explanation

Correct Answer

Inspect LACP negotiation state and physical member counters. This first check isolates the relevant mechanism without an untested configuration change. It tests the rule that lACP negotiation and bundle settings must match across peers.

Incorrect Answers

This diagnostic choice fits a different situation: Receivers on a remote multicast VLAN lose only the video stream after an uplink change. It does not resolve the stated failure mode. For this case, the decisive diagnostic choice is to inspect LACP negotiation state and physical member counters.

Question 454

An implementation change is planned for: An aggregated uplink loses half its capacity after a peer switch update. Which preventive control BEST reduces unnecessary outage and security risk?

Test policy changes against representative user and device profiles
Stage peer changes in coordination and precheck partner state
Keep approved replacement procedure and compatible software image ready
Save a reviewed baseline before every trunk edit

Explanation

Correct Answer

Stage peer changes in coordination and precheck partner state. This safeguard is appropriate before the change to restore matching LACP partner mode and consistent member policy; it reduces exposure to the mistake of converting one side to a static bundle while the other expects LACP.

Incorrect Answers

This prevention choice fits a different situation: After a RADIUS policy update authorized users cannot reach their assigned VLAN. It does not resolve the stated failure mode. For this case, the decisive prevention choice is to stage peer changes in coordination and precheck partner state.

Question 455

A first repair attempt for this situation failed: An aggregated uplink loses half its capacity after a peer switch update. The review found the mistaken approach of converting one side to a static bundle while the other expects LACP. Which targeted recovery action BEST restores the intended design?

Correct active/passive or bundle identity and revalidate member status
Restore verified baseline and document the rejected change delta
Install the supported optic and restore the saved interface mode
Align the group and ensure stable master election before returning clients

Explanation

Correct Answer

Correct active/passive or bundle identity and revalidate member status. This addresses the observed risk rather than hiding its symptoms. Confirm the repair when both members join the intended aggregator and traffic distribution returns.

Incorrect Answers

Question 456

An HPE Aruba Networking engineer faces this wired-network scenario: After a RADIUS policy update authorized users cannot reach their assigned VLAN. Which implementation action BEST addresses the requirement?

Restore the approved voice VLAN membership on the affected uplink
Correct the enforced role or VLAN attributes while preserving endpoint authentication
Restore valid PIM neighbor or reverse-path reachability for the multicast group
Correct the VRRP group and priority settings and verify peer reachability

Explanation

Correct Answer

Successful authentication does not guarantee correct network authorization. The targeted implementation is to correct the enforced role or VLAN attributes while preserving endpoint authentication. The deployment succeeds when authorized devices receive the documented segment and denied devices remain restricted.

Incorrect Answers
