HP HPE7-A08 Practice Test 45

Question 440

An implementation change is planned for: Routing disappears after an engineer assigns a different OSPF area on one uplink. Which preventive control BEST reduces unnecessary outage and security risk?

Retain tested spare optics with the site runbook
Maintain a peer-to-peer routing area worksheet
Save a reviewed baseline before every trunk edit
Stage peer changes in coordination and precheck partner state

Explanation

Correct Answer

Maintain a peer-to-peer routing area worksheet. This safeguard is appropriate before the change to restore compatible area and authentication settings on the adjacency; it reduces exposure to the mistake of redistributing every route as a substitute for fixing peer area mismatch.

Incorrect Answers

This prevention 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 prevention choice is to maintain a peer-to-peer routing area worksheet.

This prevention 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 prevention choice is to maintain a peer-to-peer routing area worksheet.

Question 441

A first repair attempt for this situation failed: Routing disappears after an engineer assigns a different OSPF area on one uplink. The review found the mistaken approach of redistributing every route as a substitute for fixing peer area mismatch. Which targeted recovery action BEST restores the intended design?

Correct the mismatched area and validate the neighbor state
Rebuild the member configuration and rejoin it using supported stack ports
Correct multicast neighbor or RPF settings and confirm intended stream
Install the supported optic and restore the saved interface mode

Explanation

Correct Answer

Correct the mismatched area and validate the neighbor state. This addresses the observed risk rather than hiding its symptoms. Confirm the repair when neighbors and intended prefixes recover without redesigning the core.

Incorrect Answers

Question 442

An HPE Aruba Networking engineer faces this wired-network scenario: An uplink stops after a maintenance crew replaces a single transceiver. Which implementation action BEST addresses the requirement?

Restore the approved voice VLAN membership on the affected uplink
Replace the incompatible optic with the verified approved transceiver type
Restore compatible area and authentication settings on the adjacency
Restore valid PIM neighbor or reverse-path reachability for the multicast group

Explanation

Correct Answer

Optical module compatibility must match port and fiber constraints. The targeted implementation is to replace the incompatible optic with the verified approved transceiver type. The deployment succeeds when the link becomes stable with acceptable receive power and error rate.

Question 443

After implementing the approved change — Replace the incompatible optic with the verified approved transceiver type — for this scenario: An uplink stops after a maintenance crew replaces a single transceiver. Which observed result BEST verifies the outcome?

All essential services return before a narrow revised change is retried
Phones regain their voice VLAN and ordinary VLANs remain unchanged
Multicast forwarding state and receiver stream return while unicast remains stable
The link becomes stable with acceptable receive power and error rate

Explanation

Correct Answer

The link becomes stable with acceptable receive power and error rate. This is the observable acceptance evidence for the decision to replace the incompatible optic with the verified approved transceiver type. It demonstrates the principle that optical module compatibility must match port and fiber constraints.

Incorrect Answers

Question 444

An HPE Aruba Networking design review examines: An uplink stops after a maintenance crew replaces a single transceiver. Which technical principle BEST explains the required approach?

Stack membership depends on hardware, software and topology compatibility
Optical module compatibility must match port and fiber constraints
LACP negotiation and bundle settings must match across peers
Multicast route distribution depends on control plane and reverse path correctness

Explanation

Correct Answer

Optical module compatibility must match port and fiber constraints. The case therefore calls for this specifically controlled action: replace the incompatible optic with the verified approved transceiver type. The acceptance evidence is that the link becomes stable with acceptable receive power and error rate.

Question 445

A risk review for the following wired-network case asks what should be avoided: An uplink stops after a maintenance crew replaces a single transceiver. Which assumption creates the GREATEST implementation risk?

Bypassing port security permanently to fix a temporary role mismatch
Converting one side to a static bundle while the other expects LACP
Redistributing every route as a substitute for fixing peer area mismatch
Forcing unsupported speed modes until an optic appears to work

Explanation

Correct Answer

Forcing unsupported speed modes until an optic appears to work. That shortcut fails because optical module compatibility must match port and fiber constraints. Instead, the appropriate approach is to replace the incompatible optic with the verified approved transceiver type.

Question 446

Before changing switch configuration, an engineer investigates: An uplink stops after a maintenance crew replaces a single transceiver. Which FIRST check is most useful for isolating the cause?

Inspect VRRP advertisements, virtual address and interface state
Compare module identity, fiber type and port capability
Inspect stack topology, member status and version differences
Inspect RPF interface, PIM state and routing changes

Explanation

Correct Answer

Compare module identity, fiber type and port capability. This first check isolates the relevant mechanism without an untested configuration change. It tests the rule that optical module compatibility must match port and fiber constraints.

Incorrect Answers
