HP HPE7-A08 Practice Test 47

Question 460

Before changing switch configuration, an engineer investigates: After a RADIUS policy update authorized users cannot reach their assigned VLAN. Which FIRST check is most useful for isolating the cause?

Review change diff, checkpoint availability and current fault timeline
Inspect RADIUS response attributes and switch role mapping
Inspect RPF interface, PIM state and routing changes
Inspect stack topology, member status and version differences

Explanation

Correct Answer

Inspect RADIUS response attributes and switch role mapping. This first check isolates the relevant mechanism without an untested configuration change. It tests the rule that successful authentication does not guarantee correct network authorization.

Incorrect Answers

This diagnostic 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 diagnostic choice is to inspect RADIUS response attributes and switch role mapping.

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 RADIUS response attributes and switch role mapping.

Question 461

An implementation change is planned for: After a RADIUS policy update authorized users cannot reach their assigned VLAN. Which preventive control BEST reduces unnecessary outage and security risk?

Test checkpoint restore commands in a controlled lab
Stage a peer-master failure test with monitored ARP behavior
Keep approved replacement procedure and compatible software image ready
Test policy changes against representative user and device profiles

Explanation

Correct Answer

Test policy changes against representative user and device profiles. This safeguard is appropriate before the change to correct the enforced role or VLAN attributes while preserving endpoint authentication; it reduces exposure to the mistake of bypassing port security permanently to fix a temporary role mismatch.

Incorrect Answers

Question 462

A first repair attempt for this situation failed: After a RADIUS policy update authorized users cannot reach their assigned VLAN. The review found the mistaken approach of bypassing port security permanently to fix a temporary role mismatch. Which targeted recovery action BEST restores the intended design?

Restore verified baseline and document the rejected change delta
Correct multicast neighbor or RPF settings and confirm intended stream
Restore the approved role mapping and force a controlled authentication refresh
Correct the mismatched area and validate the neighbor state

Explanation

Correct Answer

Restore the approved role mapping and force a controlled authentication refresh. This addresses the observed risk rather than hiding its symptoms. Confirm the repair when authorized devices receive the documented segment and denied devices remain restricted.

Incorrect Answers

Question 463

An HPE Aruba Networking engineer faces this wired-network scenario: A dual gateway pair both appear as active masters after a configuration change. Which implementation action BEST addresses the requirement?

Replace the incompatible optic with the verified approved transceiver type
Restore the approved voice VLAN membership on the affected uplink
Correct the enforced role or VLAN attributes while preserving endpoint authentication
Correct the VRRP group and priority settings and verify peer reachability

Explanation

Correct Answer

Gateway redundancy depends on consistent virtual group identity and communication. The targeted implementation is to correct the VRRP group and priority settings and verify peer reachability. The deployment succeeds when one appropriate VRRP master and a standby provide stable virtual gateway service.

Incorrect Answers

For this case, the decisive implementation choice is to correct the VRRP group and priority settings and verify peer reachability.

Question 464

After implementing the approved change — Correct the VRRP group and priority settings and verify peer reachability — for this scenario: A dual gateway pair both appear as active masters after a configuration change. Which observed result BEST verifies the outcome?

Both members join the intended aggregator and traffic distribution returns
One appropriate VRRP master and a standby provide stable virtual gateway service
The link becomes stable with acceptable receive power and error rate
The replacement member joins in the intended role and stack health is stable

Explanation

Correct Answer

One appropriate VRRP master and a standby provide stable virtual gateway service. This is the observable acceptance evidence for the decision to correct the VRRP group and priority settings and verify peer reachability. It demonstrates the principle that gateway redundancy depends on consistent virtual group identity and communication.

Incorrect Answers

This verification choice fits a different situation: An aggregated uplink loses half its capacity after a peer switch update. It does not resolve the stated failure mode. For this case, the decisive verification choice is to one appropriate VRRP master and a standby provide stable virtual gateway service.

Question 465

An HPE Aruba Networking design review examines: A dual gateway pair both appear as active masters after a configuration change. Which technical principle BEST explains the required approach?

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

Explanation

Correct Answer

Gateway redundancy depends on consistent virtual group identity and communication. The case therefore calls for this specifically controlled action: correct the VRRP group and priority settings and verify peer reachability. The acceptance evidence is that one appropriate VRRP master and a standby provide stable virtual gateway service.

Question 466

A risk review for the following wired-network case asks what should be avoided: A dual gateway pair both appear as active masters after a configuration change. Which assumption creates the GREATEST implementation risk?

Replacing whole switch configuration when one allowed-VLAN list is wrong
Leaving duplicate conflicting virtual gateways active in the same VLAN
Flooding all multicast across access VLANs as a replacement for routing
Bypassing port security permanently to fix a temporary role mismatch

Explanation

Correct Answer

Leaving duplicate conflicting virtual gateways active in the same VLAN. That shortcut fails because gateway redundancy depends on consistent virtual group identity and communication. Instead, the appropriate approach is to correct the VRRP group and priority settings and verify peer reachability.
