HP HPE7-A01 Practice Test 15
Question 140
A campus VSF stack upgrade leaves one member on a mismatched software build, preventing it from joining cleanly. The change fails acceptance. What is the safest targeted restoration action?
- Revert the minimum-link or LACP changes to known-good values and recover both members if acceptance traffic fails.
- Roll back to the last supported common stack image and isolate the incompatible member until a tested upgrade plan is ready.
- Restore the established gateway ownership and route tracking policy while remediating mismatched virtual-gateway state.
- Restore the previous stable ISL wiring and configuration before changing active-gateway behavior or reopening traffic.
Explanation
Correct Answer
B:Roll back to the last supported common stack image and isolate the incompatible member until a tested upgrade plan is ready. Stacking members must meet platform and software compatibility requirements; forcing an out-of-family member into a stack risks service interruption. The focused rollback restores a known safe baseline before another change attempt. The decision applies to the described vsf upgrade and member compatibility situation.
Incorrect Answers
A:Revert the minimum-link or LACP changes to known-good values and recover both members if acceptance traffic fails. This instead concerns lag member failure and redundancy. A redundant LAG must retain sufficient eligible members to meet its minimum-link policy; two cabled links alone do not assure survivability. It would not safely roll back the relevant failed change. The immediate problem concerns vsf upgrade and member compatibility.
C:Restore the established gateway ownership and route tracking policy while remediating mismatched virtual-gateway state. This instead concerns resilient gateway versus routing adjacency. Physical path redundancy does not automatically provide default-gateway availability; the applicable first-hop design must preserve an authorized gateway identity. It would not safely roll back the relevant failed change. The immediate problem concerns vsf upgrade and member compatibility.
D:Restore the previous stable ISL wiring and configuration before changing active-gateway behavior or reopening traffic. This instead concerns vsx inter-switch link integrity. A VSX deployment requires a healthy inter-switch link for coordinated peer functions; keepalive reachability alone does not replace it. It would not safely roll back the relevant failed change. The immediate problem concerns vsf upgrade and member compatibility.
Question 141
A replacement stack member is inserted into a production closet but remains isolated due to software and hardware compatibility differences. Before implementing a remedy, what should the engineer check first?
- Review supported member models, firmware compatibility and the stack version or image state for each member.
- Review LAG minimum-member requirements, surviving member forwarding state and peer aggregation configuration.
- Review the chosen default-gateway redundancy mechanism, virtual address ownership and routing or peer failure state.
- Review VSX peer status, inter-switch link aggregation members and the actual ISL forwarding path.
Explanation
Correct Answer
A:Review supported member models, firmware compatibility and the stack version or image state for each member. Stacking members must meet platform and software compatibility requirements; forcing an out-of-family member into a stack risks service interruption. The evidence check isolates the relevant prerequisite before a disruptive change. The decision applies to the described vsf upgrade and member compatibility situation.

Question 142
A replacement stack member is inserted into a production closet but remains isolated due to software and hardware compatibility differences. After the root cause is confirmed, which narrowly scoped configuration action should be selected?
- Repair supported LAG resilience thresholds and ensure both physical links are eligible active members before relying on failover.
- Roll out an approved compatible first-hop or active-gateway mechanism appropriate to the actual switch pair and topology.
- Correct the supported VSX ISL LAG and peer configuration while keeping the redundant topology and consistency requirements intact.
- Move the replacement member to the approved compatible software and stacking configuration before joining the production VSF.
Explanation
Correct Answer
D:Move the replacement member to the approved compatible software and stacking configuration before joining the production VSF. Stacking members must meet platform and software compatibility requirements; forcing an out-of-family member into a stack risks service interruption. The proposed configuration targets the stated dependency without broadening unrelated access. The decision applies to the described vsf upgrade and member compatibility situation.
Incorrect Answers
A:Repair supported LAG resilience thresholds and ensure both physical links are eligible active members before relying on failover. This instead concerns lag member failure and redundancy. A redundant LAG must retain sufficient eligible members to meet its minimum-link policy; two cabled links alone do not assure survivability. It would not implement the specifically required change. The immediate problem concerns vsf upgrade and member compatibility.
B:Roll out an approved compatible first-hop or active-gateway mechanism appropriate to the actual switch pair and topology. This instead concerns resilient gateway versus routing adjacency. Physical path redundancy does not automatically provide default-gateway availability; the applicable first-hop design must preserve an authorized gateway identity.

Question 143
A replacement stack member is inserted into a production closet but remains isolated due to software and hardware compatibility differences. A deployment job reports success. Which observed result would actually validate the affected service?
- Temporarily disconnect one approved test member and verify connectivity persists on the surviving link without LACP collapse.
- Verify hosts retain the advertised gateway and approved traffic during a controlled single-router or peer failure.
- Validate compatible software on every member and a stable member topology after a staged reload or failover for the affected campus deployment.
- Verify the VSX peers and ISL report healthy roles and expected state synchronization under normal load.
Explanation
Correct Answer
C:Validate compatible software on every member and a stable member topology after a staged reload or failover for the affected campus deployment. Stacking members must meet platform and software compatibility requirements; forcing an out-of-family member into a stack risks service interruption. The result tests actual working behavior, not merely a saved configuration. The decision applies to the described vsf upgrade and member compatibility situation.

Question 144
A replacement stack member is inserted into a production closet but remains isolated due to software and hardware compatibility differences. The review requires TWO complementary actions: one diagnostic check and one controlled configuration remedy. Select TWO actions that together meet those requirements.
- Review LAG minimum-member requirements, surviving member forwarding state and peer aggregation configuration.
- Review supported member models, firmware compatibility and the stack version or image state for each member.
- Roll out an approved compatible first-hop or active-gateway mechanism appropriate to the actual switch pair and topology.
- Move the replacement member to the approved compatible software and stacking configuration before joining the production VSF.
Explanation
Correct Answers
B:Review supported member models, firmware compatibility and the stack version or image state for each member. Stacking members must meet platform and software compatibility requirements; forcing an out-of-family member into a stack risks service interruption. This is the required diagnosis or controlled remedy; the other keyed action supplies the complementary role. The decision applies to the described vsf upgrade and member compatibility situation.

Question 145
A campus building has a redundant LACP distribution uplink, but removing one fiber causes the entire logical interface to drop. Which investigation would best isolate the immediate network dependency?
- Inspect the chosen default-gateway redundancy mechanism, virtual address ownership and routing or peer failure state.
- Inspect LAG minimum-member requirements, surviving member forwarding state and peer aggregation configuration.
- Inspect VSX peer status, inter-switch link aggregation members and the actual ISL forwarding path.
- Inspect VSX keepalive source and peer IP reachability separately from the inter-switch link status.
