HP HPE7-A01 Practice Test 11
Question 100
A pair of campus aggregation switches reports a VSX peer-sync failure after the inter-switch link LAG loses its active members. The change fails acceptance. What is the safest targeted restoration action?
- Restore the previous stable ISL wiring and configuration before changing active-gateway behavior or reopening traffic.
- Reinstate the previously reachable keepalive interface and route while preserving the working ISL configuration.
- Restore the last matching active-gateway parameters on both peers and verify ARP or neighbor cache convergence.
- Return the affected feature to a documented peer-consistent configuration and disable unsupported synchronization assumptions.
Explanation
Correct Answer
A:Restore the previous stable ISL wiring and configuration before changing active-gateway behavior or reopening traffic. A VSX deployment requires a healthy inter-switch link for coordinated peer functions; keepalive reachability alone does not replace it. The focused rollback restores a known safe baseline before another change attempt. The decision applies to the described vsx inter-switch link integrity situation.
Incorrect Answers
B:Reinstate the previously reachable keepalive interface and route while preserving the working ISL configuration. This instead concerns vsx keepalive versus isl failure. Keepalive and ISL supply complementary VSX control evidence; treating them as the same link obscures failure isolation. It would not safely roll back the relevant failed change. The immediate problem concerns vsx inter-switch link integrity.
C:Restore the last matching active-gateway parameters on both peers and verify ARP or neighbor cache convergence. This instead concerns vsx active-gateway consistency. VSX active gateway depends on consistent virtual gateway identity; uncoordinated peer settings cause intermittent forwarding failures. It would not safely roll back the relevant failed change. The immediate problem concerns vsx inter-switch link integrity.
D:Return the affected feature to a documented peer-consistent configuration and disable unsupported synchronization assumptions. This instead concerns vsx synchronization scope. VSX synchronizes only supported selected configuration categories; peer devices remain independent control planes with some intentionally distinct settings. It would not safely roll back the relevant failed change. The immediate problem concerns vsx inter-switch link integrity.
Question 101
A redundant distribution pair continues to pass some traffic but VSX status shows the ISL down after a fiber migration. The review requires TWO complementary actions: one diagnostic check and one controlled configuration remedy. Select TWO actions that together meet those requirements.
- Review VSX keepalive source and peer IP reachability separately from the inter-switch link status.
- Review VSX peer status, inter-switch link aggregation members and the actual ISL forwarding path.
- Set up a consistent supported VSX active-gateway address and virtual MAC across corresponding gateway interfaces.
- Correct the supported VSX ISL LAG and peer configuration while keeping the redundant topology and consistency requirements intact.
Explanation
Correct Answers
B:Review VSX peer status, inter-switch link aggregation members and the actual ISL forwarding path. A VSX deployment requires a healthy inter-switch link for coordinated peer functions; keepalive reachability alone does not replace it. This is the required diagnosis or controlled remedy; the other keyed action supplies the complementary role. The decision applies to the described vsx inter-switch link integrity situation.
D:Correct the supported VSX ISL LAG and peer configuration while keeping the redundant topology and consistency requirements intact. A VSX deployment requires a healthy inter-switch link for coordinated peer functions; keepalive reachability alone does not replace it. This is the required diagnosis or controlled remedy; the other keyed action supplies the complementary role. The decision applies to the described vsx inter-switch link integrity situation.
Incorrect Answers
A:Review VSX keepalive source and peer IP reachability separately from the inter-switch link status. This instead concerns vsx keepalive versus isl failure. Keepalive and ISL supply complementary VSX control evidence; treating them as the same link obscures failure isolation. It is not one of the requested paired diagnosis and configuration actions. The immediate problem concerns vsx inter-switch link integrity.
C:Set up a consistent supported VSX active-gateway address and virtual MAC across corresponding gateway interfaces. This instead concerns vsx active-gateway consistency. VSX active gateway depends on consistent virtual gateway identity; uncoordinated peer settings cause intermittent forwarding failures. It is not one of the requested paired diagnosis and configuration actions. The immediate problem concerns vsx inter-switch link integrity.
Question 102
A redundant distribution pair continues to pass some traffic but VSX status shows the ISL down after a fiber migration. After the root cause is confirmed, which narrowly scoped configuration action should be selected?
- Reinstate a supported independent peer keepalive path with correct routing without using the ISL as its sole failure domain.
- Set up a consistent supported VSX active-gateway address and virtual MAC across corresponding gateway interfaces.
- Correct the supported VSX ISL LAG and peer configuration while keeping the redundant topology and consistency requirements intact.
- Activate supported synchronization for the intended configuration contexts and make controlled local-only exceptions explicitly.
Explanation
Correct Answer
C:Correct the supported VSX ISL LAG and peer configuration while keeping the redundant topology and consistency requirements intact. A VSX deployment requires a healthy inter-switch link for coordinated peer functions; keepalive reachability alone does not replace it. The proposed configuration targets the stated dependency without broadening unrelated access. The decision applies to the described vsx inter-switch link integrity situation.
Incorrect Answers
A:Reinstate a supported independent peer keepalive path with correct routing without using the ISL as its sole failure domain. This instead concerns vsx keepalive versus isl failure. Keepalive and ISL supply complementary VSX control evidence; treating them as the same link obscures failure isolation. It would not implement the specifically required change. The immediate problem concerns vsx inter-switch link integrity.
B:Set up a consistent supported VSX active-gateway address and virtual MAC across corresponding gateway interfaces. This instead concerns vsx active-gateway consistency. VSX active gateway depends on consistent virtual gateway identity; uncoordinated peer settings cause intermittent forwarding failures. It would not implement the specifically required change. The immediate problem concerns vsx inter-switch link integrity.
D:Activate supported synchronization for the intended configuration contexts and make controlled local-only exceptions explicitly. This instead concerns vsx synchronization scope. VSX synchronizes only supported selected configuration categories; peer devices remain independent control planes with some intentionally distinct settings. It would not implement the specifically required change. The immediate problem concerns vsx inter-switch link integrity.
Question 103
A redundant distribution pair continues to pass some traffic but VSX status shows the ISL down after a fiber migration. A deployment job reports success. Which observed result would actually validate the affected service?
- Verify stable keepalive probe results and healthy VSX dual-peer status across a controlled path test.
- Verify the VSX peers and ISL report healthy roles and expected state synchronization under normal load.
- Confirm either uplink path reaches the same default gateway and client traffic survives a controlled peer disruption.
- Validate the selected feature is consistent on both peers while intended independent interfaces remain unique for the affected campus deployment.
Explanation
Correct Answer
B:Verify the VSX peers and ISL report healthy roles and expected state synchronization under normal load. A VSX deployment requires a healthy inter-switch link for coordinated peer functions; keepalive reachability alone does not replace it. The result tests actual working behavior, not merely a saved configuration. The decision applies to the described vsx inter-switch link integrity situation.

Question 105
A VSX switch pair loses its separate keepalive path while the ISL remains healthy, prompting an operator to disable split-brain protection. Which investigation would best isolate the immediate network dependency?
- Inspect VSX keepalive source and peer IP reachability separately from the inter-switch link status.
- Compare active-gateway virtual IP and shared MAC configuration on both peers for the affected VLAN.
- Inspect configured VSX synchronization categories and the current configuration diff for the relevant feature.
- Inspect VSF member IDs, conductor or standby state and dedicated stacking-link port health.
Explanation
Correct Answer
A:Inspect VSX keepalive source and peer IP reachability separately from the inter-switch link status. Keepalive and ISL supply complementary VSX control evidence; treating them as the same link obscures failure isolation. The evidence check isolates the relevant prerequisite before a disruptive change. The decision applies to the described vsx keepalive versus isl failure situation.
Incorrect Answers
B:Compare active-gateway virtual IP and shared MAC configuration on both peers for the affected VLAN. This instead concerns vsx active-gateway consistency. VSX active gateway depends on consistent virtual gateway identity; uncoordinated peer settings cause intermittent forwarding failures. It does not isolate the cause of the stated incident.

D:Inspect VSF member IDs, conductor or standby state and dedicated stacking-link port health. This instead concerns vsf member and conductor status. VSF provides a single logical switch across supported members, which differs from independent VSX peer devices and their ISL. It does not isolate the cause of the stated incident. The immediate problem concerns vsx keepalive versus isl failure.
Question 106
A VSX switch pair loses its separate keepalive path while the ISL remains healthy, prompting an operator to disable split-brain protection. Which specific corrective design step best meets the stated campus requirement?
