Question 500

The HPE AOS-CX switching case is: A BGP session is established but a route filter denies every prefix required for the new branch. Select TWO: a corrective switching action and separate evidence that the correction worked. (Select TWO.)

  1. A reconciled configuration diff and focused service tests prove only intended changes were recovered and recorded.
  2. Use route tables, interface IPs, neighbor state and policy output to repair the specific missing or incorrect Layer 3 adjacency or prefix.
  3. The neighbor reaches its designed state, intended routes appear in the correct VRF and bidirectional probes succeed.
  4. Inspect classification, queue occupancy, drops and congestion points before tuning DSCP, shaping or scheduling policies.
  5. Separate IGMP snooping, querier state, PIM neighbor and RPF checks to find multicast loss at its real layer.

Explanation

Correct Answers

B:

The targeted correction for A BGP session is established but a route filter denies every prefix required for the new branch is: Use route tables, interface IPs, neighbor state and policy output to repair the specific missing or incorrect Layer 3 adjacency or prefix. It reduces the risk that adding arbitrary static routes can hide an OSPF or BGP configuration defect and later cause asymmetric return traffic.

C:

A separate operational validation for A BGP session is established but a route filter denies every prefix required for the new branch is: The neighbor reaches its designed state, intended routes appear in the correct VRF and bidirectional probes succeed. It proves intended behavior instead of accepting configuration presence alone.

Incorrect Answers

A:

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 BGP session is established but a route filter denies every prefix required for the new branch requires the more specific routed-path recovery and ospf/bgp neighbor remediation control. The targeted action is: Use route tables, interface IPs, neighbor state and policy output to repair the specific missing or incorrect Layer 3 adjacency or prefix.

D:

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 BGP session is established but a route filter denies every prefix required for the new branch requires the more specific routed-path recovery and ospf/bgp neighbor remediation control. The targeted action is: Use route tables, interface IPs, neighbor state and policy output to repair the specific missing or incorrect Layer 3 adjacency or prefix.

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 BGP session is established but a route filter denies every prefix required for the new branch requires the more specific routed-path recovery and ospf/bgp neighbor remediation control. The targeted action is: Use route tables, interface IPs, neighbor state and policy output to repair the specific missing or incorrect Layer 3 adjacency or prefix.

Question 501

An HPE Aruba Networking engineer observes: A new access SVI has no reciprocal return route at the server distribution border. The corrective solution must keep intended connectivity, segmentation, and operational resilience. Which implementation or troubleshooting step directly resolves the specific network issue?

  1. Separate IGMP snooping, querier state, PIM neighbor and RPF checks to find multicast loss at its real layer.
  2. Diagnose failures with a reproducible path from endpoint addressing through port, VLAN, gateway, routing and application dependency.
  3. Use route tables, interface IPs, neighbor state and policy output to repair the specific missing or incorrect Layer 3 adjacency or prefix.
  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: A new access SVI has no reciprocal return route at the server distribution border. The appropriate switching action is: Use route tables, interface IPs, neighbor state and policy output to repair the specific missing or incorrect Layer 3 adjacency or prefix. It addresses the risk that adding arbitrary static routes can hide an OSPF or BGP configuration defect and later cause asymmetric return traffic. Confirm with: The neighbor reaches its designed state, intended routes appear in the correct VRF and bidirectional probes succeed.

Incorrect Answers

A:

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 A new access SVI has no reciprocal return route at the server distribution border requires the more specific routed-path recovery and ospf/bgp neighbor remediation control. The targeted action is: Use route tables, interface IPs, neighbor state and policy output to repair the specific missing or incorrect Layer 3 adjacency or prefix.

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 A new access SVI has no reciprocal return route at the server distribution border requires the more specific routed-path recovery and ospf/bgp neighbor remediation control. The targeted action is: Use route tables, interface IPs, neighbor state and policy output to repair the specific missing or incorrect Layer 3 adjacency or prefix.

Question 502

An engineer investigates: A new access SVI has no reciprocal return route at the server distribution border. What network observation should the team require before approving completion?

  1. The neighbor reaches its designed state, intended routes appear in the correct VRF and bidirectional probes succeed.
  2. A known receiver gets the stream and unsubscribed ports remain protected after the correct membership or routing fix.
  3. A documented test sequence localizes the first failed hop and confirms recovery without broad unapproved changes.
  4. A before/after event timeline and counters show the original fault stopped with no unexpected new alerts.

Explanation

Correct Answer

A:

The independent acceptance evidence for A new access SVI has no reciprocal return route at the server distribution border is: The neighbor reaches its designed state, intended routes appear in the correct VRF and bidirectional probes succeed. It tests whether the team has actually implemented: Use route tables, interface IPs, neighbor state and policy output to repair the specific missing or incorrect Layer 3 adjacency or prefix. An enabled interface or saved configuration by itself is not evidence of complete service recovery.

Incorrect Answers

B:

Question 504

The switch operations team reports: A static default path overrides a working dynamic route after a firmware replacement and remote reachability becomes intermittent. Which consequence explains why the described network state is unsuitable?

  1. Blind restoration from a stale backup may overwrite healthy newer policies and leave a hidden repeat-failure trigger.
  2. A remediation based on uncorrelated symptoms can fix a side effect while the actual trigger remains active.
  3. Adding arbitrary static routes can hide an OSPF or BGP configuration defect and later cause asymmetric return traffic.
  4. Enabling more multicast flooding without diagnosis can overload unrelated VLANs and still fail inter-subnet delivery.

Explanation

Correct Answer

C:

The direct operational failure mode is: Adding arbitrary static routes can hide an OSPF or BGP configuration defect and later cause asymmetric return traffic.
