Question 660

After implementing the approved change — Correlate route-neighbor state changes with logging, interface health and planned jobs — for this scenario: An OSPF core reports adjacency oscillation at the same time daily. Which observed result BEST verifies the outcome?

The review distinguishes benign counters from a growing physical fault
The event record identifies a reproducible transition and candidate cause
The health report distinguishes the affected peer link from the keepalive channel
Authorized operators can see validated client records without broadening access

Explanation

Correct Answer

The event record identifies a reproducible transition and candidate cause. This is the observable acceptance evidence for the decision to correlate route-neighbor state changes with logging, interface health and planned jobs. It demonstrates the principle that routing stability requires time-correlated evidence rather than a single snapshot.

Incorrect Answers

This verification choice fits a different situation: An uplink seems healthy but the monitoring system shows steadily increasing receive errors. It does not resolve the stated failure mode. For this case, the decisive verification choice is to the event record identifies a reproducible transition and candidate cause.

For this case, the decisive verification choice is to the event record identifies a reproducible transition and candidate cause.

Question 661

An HPE Aruba Networking design review examines: An OSPF core reports adjacency oscillation at the same time daily. Which technical principle BEST explains the required approach?

Client authorization health requires protocol and role telemetry
Counter trends reveal problems that simple up/down signals miss
Management connectivity and client-visibility instrumentation are separate
Routing stability requires time-correlated evidence rather than a single snapshot

Explanation

Correct Answer

Routing stability requires time-correlated evidence rather than a single snapshot. The case therefore calls for this specifically controlled action: correlate route-neighbor state changes with logging, interface health and planned jobs. The acceptance evidence is that the event record identifies a reproducible transition and candidate cause.

Question 662

A risk review for the following wired-network case asks what should be avoided: An OSPF core reports adjacency oscillation at the same time daily. Which assumption creates the GREATEST implementation risk?

Treating the absence of a helpdesk ticket as proof no link fault occurred
Clearing OSPF neighbors periodically as a permanent monitoring fix
Treating a stack with no standby as fully redundant
Calling both switches healthy simply because both respond to SSH

Explanation

Correct Answer

Clearing OSPF neighbors periodically as a permanent monitoring fix. That shortcut fails because routing stability requires time-correlated evidence rather than a single snapshot. Instead, the appropriate approach is to correlate route-neighbor state changes with logging, interface health and planned jobs.

Incorrect Answers

Question 663

Before changing switch configuration, an engineer investigates: An OSPF core reports adjacency oscillation at the same time daily. Which FIRST check is most useful for isolating the cause?

Inspect NAE script conditions, active agents and event timing
Inspect Central device context, client-tracking setting and reported endpoints
Inspect exporter configuration, sample rates and collector ingestion
Inspect neighbor history, link-state events and maintenance schedules

Explanation

Correct Answer

Inspect neighbor history, link-state events and maintenance schedules. This first check isolates the relevant mechanism without an untested configuration change. It tests the rule that routing stability requires time-correlated evidence rather than a single snapshot.

Incorrect Answers

This diagnostic choice fits a different situation: The network team wants automated detection of a repeated port-flap pattern. It does not resolve the stated failure mode. For this case, the decisive diagnostic choice is to inspect neighbor history, link-state events and maintenance schedules.

For this case, the decisive diagnostic choice is to inspect neighbor history, link-state events and maintenance schedules.

Question 664

An implementation change is planned for: An OSPF core reports adjacency oscillation at the same time daily. Which preventive control BEST reduces unnecessary outage and security risk?

Set alert severity and suppression according to service impact
Preserve routing state telemetry across known maintenance windows
Set thresholds and retain historical baselines
Alert separately on ISL synchronization and keepalive degradation

Explanation

Correct Answer

Preserve routing state telemetry across known maintenance windows. This safeguard is appropriate before the change to correlate route-neighbor state changes with logging, interface health and planned jobs; it reduces exposure to the mistake of clearing OSPF neighbors periodically as a permanent monitoring fix.

Incorrect Answers

This prevention choice fits a different situation: A central operations dashboard lacks alerts when a core link goes down. It does not resolve the stated failure mode. For this case, the decisive prevention choice is to preserve routing state telemetry across known maintenance windows.

Question 665

A first repair attempt for this situation failed: An OSPF core reports adjacency oscillation at the same time daily. The review found the mistaken approach of clearing OSPF neighbors periodically as a permanent monitoring fix. Which targeted recovery action BEST restores the intended design?

Correct the triggering interface or job and verify stable adjacency
Replace or reconfigure the absent standby and validate failover
Enable the supported client-tracking data path and retest visibility
Adjust queue or capacity policy based on verified microburst measurements

Explanation

Correct Answer

Correct the triggering interface or job and verify stable adjacency. This addresses the observed risk rather than hiding its symptoms. Confirm the repair when the event record identifies a reproducible transition and candidate cause.

Incorrect Answers

Use sampled flow telemetry such as supported sFlow reporting to an approved collector
Review device telemetry visibility, group context and required client tracking settings

Explanation
