Question 510

The HPE AOS-CX switching case is: A primary peer shows out-of-sync settings and an operator assumes all secondary configurations are identical automatically. Which TWO choices together provide the targeted remedy and independent validation? (Select TWO.)

  1. Remediate VSX state only after checking ISL, keepalive, peer roles and configuration synchronization with a documented change plan.
  2. Inspect classification, queue occupancy, drops and congestion points before tuning DSCP, shaping or scheduling policies.
  3. Recover missing VSF members using supported identity, link, conductor and software checks rather than resetting the logical stack without evidence.
  4. A single-peer failover and recovery test confirms consistent active gateway and restored VSX operational health.
  5. A known receiver gets the stream and unsubscribed ports remain protected after the correct membership or routing fix.

Explanation

Correct Answers

A:

The targeted correction for A primary peer shows out-of-sync settings and an operator assumes all secondary configurations are identical automatically is: Remediate VSX state only after checking ISL, keepalive, peer roles and configuration synchronization with a documented change plan. It reduces the risk that blindly reloading both peers can turn a recoverable link issue into a complete campus distribution outage.

D:

A separate operational validation for A primary peer shows out-of-sync settings and an operator assumes all secondary configurations are identical automatically is: A single-peer failover and recovery test confirms consistent active gateway and restored VSX operational health. It proves intended behavior instead of accepting configuration presence alone.

Incorrect Answers

B:

This alternative concerns qos congestion remediation using actual queue telemetry; its associated risk is: Changing priority globally based on one poor call can starve critical classes or fail to address an undersized physical uplink. The observed case A primary peer shows out-of-sync settings and an operator assumes all secondary configurations are identical automatically requires the more specific vsx high availability and recovery action sequencing control. The targeted action is: Remediate VSX state only after checking ISL, keepalive, peer roles and configuration synchronization with a documented change plan.

C:

This alternative concerns vsf membership and conductor recovery plan; its associated risk is: Unplanned zeroization or member readdition can erase interface configuration and extend an access outage. The observed case A primary peer shows out-of-sync settings and an operator assumes all secondary configurations are identical automatically requires the more specific vsx high availability and recovery action sequencing control. The targeted action is: Remediate VSX state only after checking ISL, keepalive, peer roles and configuration synchronization with a documented change plan.

E:

This alternative concerns multicast join and routed multicast fault recovery; its associated risk is: Enabling more multicast flooding without diagnosis can overload unrelated VLANs and still fail inter-subnet delivery. The observed case A primary peer shows out-of-sync settings and an operator assumes all secondary configurations are identical automatically requires the more specific vsx high availability and recovery action sequencing control. The targeted action is: Remediate VSX state only after checking ISL, keepalive, peer roles and configuration synchronization with a documented change plan.

Question 511

An HPE Aruba Networking engineer observes: An intermittent gateway issue is blamed on OSPF while the two VSX peers use inconsistent active-gateway MAC values. The corrective solution must keep intended connectivity, segmentation, and operational resilience. Which response best satisfies the technical requirement without disrupting unrelated traffic?

  1. Resolve blocked wired devices by reviewing RADIUS status, assigned roles, MAC authorization and policy logs without bypassing security wholesale.
  2. Diagnose failures with a reproducible path from endpoint addressing through port, VLAN, gateway, routing and application dependency.
  3. Remediate VSX state only after checking ISL, keepalive, peer roles and configuration synchronization with a documented change plan.
  4. Correlate time-synchronized switch logs, counters and recent configuration changes before replacing hardware or changing protocols.

Explanation

Correct Answer

C:

The decisive observed condition is: An intermittent gateway issue is blamed on OSPF while the two VSX peers use inconsistent active-gateway MAC values. The appropriate switching action is: Remediate VSX state only after checking ISL, keepalive, peer roles and configuration synchronization with a documented change plan.

Confirm with: A single-peer failover and recovery test confirms consistent active gateway and restored VSX operational health.

Incorrect Answers

A:

This alternative concerns port security and aaa fault remediation; its associated risk is: Disabling authentication for an entire building may restore connectivity while exposing unauthorized access to enterprise VLANs. The observed case An intermittent gateway issue is blamed on OSPF while the two VSX peers use inconsistent active-gateway MAC values requires the more specific vsx high availability and recovery action sequencing control. The targeted action is: Remediate VSX state only after checking ISL, keepalive, peer roles and configuration synchronization with a documented change plan.

B:

This alternative concerns structured fault isolation from endpoint to core; its associated risk is: Changing unrelated switching settings before locating the break can introduce secondary outages and destroy useful evidence. The observed case An intermittent gateway issue is blamed on OSPF while the two VSX peers use inconsistent active-gateway MAC values requires the more specific vsx high availability and recovery action sequencing control. The targeted action is: Remediate VSX state only after checking ISL, keepalive, peer roles and configuration synchronization with a documented change plan.

D:

This alternative concerns logs event timeline and interface counters remediation; its associated risk is: A remediation based on uncorrelated symptoms can fix a side effect while the actual trigger remains active. The observed case An intermittent gateway issue is blamed on OSPF while the two VSX peers use inconsistent active-gateway MAC values requires the more specific vsx high availability and recovery action sequencing control. The targeted action is: Remediate VSX state only after checking ISL, keepalive, peer roles and configuration synchronization with a documented change plan.

Question 512

The switch operations team reports: An intermittent gateway issue is blamed on OSPF while the two VSX peers use inconsistent active-gateway MAC values. What adverse switching behavior should the engineer anticipate?

  1. Disabling authentication for an entire building may restore connectivity while exposing unauthorized access to enterprise VLANs.
  2. Changing unrelated switching settings before locating the break can introduce secondary outages and destroy useful evidence.
  3. A remediation based on uncorrelated symptoms can fix a side effect while the actual trigger remains active.
  4. Blindly reloading both peers can turn a recoverable link issue into a complete campus distribution outage.

Explanation

Correct Answer

D:

The direct operational failure mode is: Blindly reloading both peers can turn a recoverable link issue into a complete campus distribution outage. It applies to the condition An intermittent gateway issue is blamed on OSPF while the two VSX peers use inconsistent active-gateway MAC values.

Question 513

An HPE Aruba Networking engineer observes: A replacement access switch is joined with the wrong VSF member number and its designated port settings disappear. The corrective solution must keep intended connectivity, segmentation, and operational resilience. Which change best addresses the observed switching requirement?

  1. Remediate VSX state only after checking ISL, keepalive, peer roles and configuration synchronization with a documented change plan.
  2. Compare intended configuration, startup state, Central templates and recent changes before restoring only the approved affected scope.
  3. Use route tables, interface IPs, neighbor state and policy output to repair the specific missing or incorrect Layer 3 adjacency or prefix.
  4. Recover missing VSF members using supported identity, link, conductor and software checks rather than resetting the logical stack without evidence.

Explanation

Correct Answer

D:

The decisive observed condition is: A replacement access switch is joined with the wrong VSF member number and its designated port settings disappear. The appropriate switching action is: Recover missing VSF members using supported identity, link, conductor and software checks rather than resetting the logical stack without evidence. It addresses the risk that unplanned zeroization or member readdition can erase interface configuration and extend an access outage. Confirm with: All expected members and ports rejoin the intended VSF inventory with preserved interface roles and healthy conductor election.

Incorrect Answers

A:

This alternative concerns vsx high availability and recovery action sequencing; its associated risk is: Blindly reloading both peers can turn a recoverable link issue into a complete campus distribution outage. The observed case A replacement access switch is joined with the wrong VSF member number and its designated port settings disappear requires the more specific vsf membership and conductor recovery plan control. The targeted action is: Recover missing VSF members using supported identity, link, conductor and software checks rather than resetting the logical stack without evidence.

B:

This alternative concerns configuration drift and restore after an outage; its associated risk is: Blind restoration from a stale backup may overwrite healthy newer policies and leave a hidden repeat-failure trigger. The observed case A replacement access switch is joined with the wrong VSF member number and its designated port settings disappear requires the more specific vsf membership and conductor recovery plan control. The targeted action is: Recover missing VSF members using supported identity, link, conductor and software checks rather than resetting the logical stack without evidence.

C:

This alternative concerns routed-path recovery and ospf/bgp neighbor remediation; its associated risk is: Adding arbitrary static routes can hide an OSPF or BGP configuration defect and later cause asymmetric return traffic. The observed case A replacement access switch is joined with the wrong VSF member number and its designated port settings disappear requires the more specific vsf membership and conductor recovery plan control. The targeted action is: Recover missing VSF members using supported identity, link, conductor and software checks rather than resetting the logical stack without evidence.

Question 514

An engineer investigates: A replacement access switch is joined with the wrong VSF member number and its designated port settings disappear. What acceptance evidence most directly demonstrates the correction succeeded?

  1. The neighbor reaches its designed state, intended routes appear in the correct VRF and bidirectional probes succeed.
  2. A reconciled configuration diff and focused service tests prove only intended changes were recovered and recorded.
  3. A single-peer failover and recovery test confirms consistent active gateway and restored VSX operational health.
  4. All expected members and ports rejoin the intended VSF inventory with preserved interface roles and healthy conductor election.

Explanation

Correct Answer

D:

The independent acceptance evidence for A replacement access switch is joined with the wrong VSF member number and its designated port settings disappear is: All expected members and ports rejoin the intended VSF inventory with preserved interface roles and healthy conductor election. It tests whether the team has actually implemented: Recover missing VSF members using supported identity, link, conductor and software checks rather than resetting the logical stack without evidence. An enabled interface or saved configuration by itself is not evidence of complete service recovery.

The targeted action is: Recover missing VSF members using supported identity, link, conductor and software checks rather than resetting the logical stack without evidence.

Question 515

An HPE Aruba Networking engineer observes: A support engineer applies a template without the required VSF member declaration on a supported release and risks a reset. The corrective solution must keep intended connectivity, segmentation, and operational resilience. What is the most defensible operational action before closing the network change?

  1. Recover missing VSF members using supported identity, link, conductor and software checks rather than resetting the logical stack without evidence.
  2. Diagnose failures with a reproducible path from endpoint addressing through port, VLAN, gateway, routing and application dependency.
  3. Remediate VSX state only after checking ISL, keepalive, peer roles and configuration synchronization with a documented change plan.
  4. Separate IGMP snooping, querier state, PIM neighbor and RPF checks to find multicast loss at its real layer.
