HP HPE7-A01 Practice Test 12
Question 110
A redundant campus core has intermittent VSX keepalive failures caused by a management VRF route change, though the ISL is still forwarding. After the root cause is confirmed, which narrowly scoped configuration action should be selected?
- Set up a consistent supported VSX active-gateway address and virtual MAC across corresponding gateway interfaces.
- Activate supported synchronization for the intended configuration contexts and make controlled local-only exceptions explicitly.
- Correct compatible VSF member identities and stacking links using the device family supported procedure.
- Reinstate a supported independent peer keepalive path with correct routing without using the ISL as its sole failure domain.
Explanation
Correct Answer
D:Reinstate a supported independent peer keepalive path with correct routing without using the ISL as its sole failure domain. Keepalive and ISL supply complementary VSX control evidence; treating them as the same link obscures failure isolation. The proposed configuration targets the stated dependency without broadening unrelated access. The decision applies to the described vsx keepalive versus isl failure situation.
Incorrect Answers
A: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 keepalive versus isl failure.
B: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 keepalive versus isl failure.
C:Correct compatible VSF member identities and stacking links using the device family supported procedure. 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 would not implement the specifically required change. The immediate problem concerns vsx keepalive versus isl failure.
Question 111
A redundant campus core has intermittent VSX keepalive failures caused by a management VRF route change, though the ISL is still forwarding. A deployment job reports success. Which observed result would actually validate the affected service?
- 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.
- Verify stable keepalive probe results and healthy VSX dual-peer status across a controlled path test.
- Verify all members join the same stack and their uplink or access interfaces reappear under the expected logical system.
Explanation
Correct Answer
C:Verify stable keepalive probe results and healthy VSX dual-peer status across a controlled path test. Keepalive and ISL supply complementary VSX control evidence; treating them as the same link obscures failure isolation. The result tests actual working behavior, not merely a saved configuration. The decision applies to the described vsx keepalive versus isl failure situation.
Incorrect Answers
A:Confirm either uplink path reaches the same default gateway and client traffic survives a controlled peer disruption. 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 establish that this function actually works. The immediate problem concerns vsx keepalive versus isl failure.
B:Validate the selected feature is consistent on both peers while intended independent interfaces remain unique for the affected campus deployment. 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 establish that this function actually works. The immediate problem concerns vsx keepalive versus isl failure.
D:Verify all members join the same stack and their uplink or access interfaces reappear under the expected logical system. 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 would not establish that this function actually works. The immediate problem concerns vsx keepalive versus isl failure.
Question 112
A redundant campus core has intermittent VSX keepalive failures caused by a management VRF route change, though the ISL is still forwarding. The review requires TWO complementary actions: one diagnostic check and one controlled configuration remedy. Select TWO actions that together meet those requirements.
- Cross-check active-gateway virtual IP and shared MAC configuration on both peers for the affected VLAN.
- Review VSX keepalive source and peer IP reachability separately from the inter-switch link status.
- Activate supported synchronization for the intended configuration contexts and make controlled local-only exceptions explicitly.
- Reinstate a supported independent peer keepalive path with correct routing without using the ISL as its sole failure domain.
Explanation
Correct Answers
B:Review 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. This is the required diagnosis or controlled remedy; the other keyed action supplies the complementary role. The decision applies to the described vsx keepalive versus isl failure situation.
D:Reinstate a supported independent peer keepalive path with correct routing without using the ISL as its sole failure domain. Keepalive and ISL supply complementary VSX control evidence; treating them as the same link obscures failure isolation. This is the required diagnosis or controlled remedy; the other keyed action supplies the complementary role. The decision applies to the described vsx keepalive versus isl failure situation.
Incorrect Answers
A:Cross-check 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 is not one of the requested paired diagnosis and configuration actions. The immediate problem concerns vsx keepalive versus isl failure.
C: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 is not one of the requested paired diagnosis and configuration actions. The immediate problem concerns vsx keepalive versus isl failure.
Question 113
Clients in one VLAN switch between two VSX peer gateways and intermittently lose their default gateway after an active-gateway MAC mismatch. Which investigation would best isolate the immediate network dependency?
- Inspect configured VSX synchronization categories and the current configuration diff for the relevant feature.
- Compare active-gateway virtual IP and shared MAC configuration on both peers for the affected VLAN.
- Inspect VSF member IDs, conductor or standby state and dedicated stacking-link port health.
- Inspect supported member models, firmware compatibility and the stack version or image state for each member.
Explanation
Correct Answer
B:Compare active-gateway virtual IP and shared MAC configuration on both peers for the affected VLAN. VSX active gateway depends on consistent virtual gateway identity; uncoordinated peer settings cause intermittent forwarding failures. The evidence check isolates the relevant prerequisite before a disruptive change. The decision applies to the described vsx active-gateway consistency situation.
Incorrect Answers
A:Inspect configured VSX synchronization categories and the current configuration diff for the relevant feature. 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 does not isolate the cause of the stated incident. The immediate problem concerns vsx active-gateway consistency.
C: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 active-gateway consistency.
D:Inspect supported member models, firmware compatibility and the stack version or image state for each member. This instead concerns vsf upgrade and member compatibility. Stacking members must meet platform and software compatibility requirements; forcing an out-of-family member into a stack risks service interruption. It does not isolate the cause of the stated incident. The immediate problem concerns vsx active-gateway consistency.
Question 114
Clients in one VLAN switch between two VSX peer gateways and intermittently lose their default gateway after an active-gateway MAC mismatch. Which specific corrective design step best meets the stated campus requirement?
- Configure a consistent supported VSX active-gateway address and virtual MAC across corresponding gateway interfaces.
- Enable supported synchronization for the intended configuration contexts and make controlled local-only exceptions explicitly.
- Repair compatible VSF member identities and stacking links using the device family supported procedure.
- Bring the replacement member to the approved compatible software and stacking configuration before joining the production VSF.
Explanation
Correct Answer
A:Configure a consistent supported VSX active-gateway address and virtual MAC across corresponding gateway interfaces. VSX active gateway depends on consistent virtual gateway identity; uncoordinated peer settings cause intermittent forwarding failures. The proposed configuration targets the stated dependency without broadening unrelated access. The decision applies to the described vsx active-gateway consistency situation.

Question 115
Clients in one VLAN switch between two VSX peer gateways and intermittently lose their default gateway after an active-gateway MAC mismatch. Following a targeted change, which acceptance test would most directly demonstrate success?
- Validate the selected feature is consistent on both peers while intended independent interfaces remain unique.
- Confirm all members join the same stack and their uplink or access interfaces reappear under the expected logical system.
- Validate compatible software on every member and a stable member topology after a staged reload or failover.
- Verify either uplink path reaches the same default gateway and client traffic survives a controlled peer disruption.
Explanation

Question 116
Clients in one VLAN switch between two VSX peer gateways and intermittently lose their default gateway after an active-gateway MAC mismatch. The change fails acceptance. What is the safest targeted restoration action?
- Return the affected feature to a documented peer-consistent configuration and disable unsupported synchronization assumptions.
- Restore the former working stack-link connections and member addressing before proceeding with a broader stack upgrade.
- Restore the last matching active-gateway parameters on both peers and verify ARP or neighbor cache convergence.
- Roll back to the last supported common stack image and isolate the incompatible member until a tested upgrade plan is ready.
Explanation
Correct Answer
C:Restore the last matching active-gateway parameters on both peers and verify ARP or neighbor cache convergence. VSX active gateway depends on consistent virtual gateway identity; uncoordinated peer settings cause intermittent forwarding failures. The focused rollback restores a known safe baseline before another change attempt. The decision applies to the described vsx active-gateway consistency situation.
Incorrect Answers
A:Return the affected feature to a documented peer-consistent configuration and disable unsupported synchronization assumptions. This instead concerns vsx synchronization scope.
