Question 890
A periodic job must flag changed configuration hashes for human review, not auto-commit changes. What should it store?
- Secure API secrets and collected data
- Collect configuration hashes or diffs
- Use least-privilege read-only API identity
- Read immutable device identity and software details
Explanation
Correct Answer
B:An approved baseline hash and current snapshot diff. Comparing approved baseline hashes to live configuration helps detect unreviewed drift.
Incorrect Answers
A:Tokens, session credentials and inventory content require approved secret storage and restricted logging. But this does not address the case requirement to identify configuration divergence.
C:Observation scripts should not gain unnecessary write or delete permissions across a network estate. But this does not address the case requirement to identify configuration divergence.
D:Asset and release inventory should derive from actual device attributes rather than assumed labels. But this does not address the case requirement to identify configuration divergence.
Question 891
A polling loop hits hundreds of 429 responses but instantly retries every request. Which robust behavior is missing?
- Read immutable device identity and software details
- Capture time-stamped structured audit results
- Collect configuration hashes or diffs
- Rate-limit and retry safely under API errors
Explanation
Correct Answer
D:Implement API error handling with finite exponential backoff. Respectful request pacing, backoff and finite retries protect platform resources and avoid uncontrolled loops.
Incorrect Answers
A:Asset and release inventory should derive from actual device attributes rather than assumed labels. But this does not address the case requirement to respect management service rate limits.
B:A reliable job records device ID, time, version, collection status and evidence for every audit. But this does not address the case requirement to respect management service rate limits.
C:Comparing approved baseline hashes to live configuration helps detect unreviewed drift. But this does not address the case requirement to respect management service rate limits.
Question 892
An API program plans to add VLAN 210, but it might already exist with different settings. What should happen before a write?
- Verify postchange effective state
- Implement idempotent reconciliation
- Read and validate current state before write
- Record authenticated change provenance
Explanation
Correct Answer
C:Read the current resource and compare it with the approved desired state. Preflight observation ensures a proposed API change is required and does not overwrite a newer operator edit.
Incorrect Answers
A:After an accepted API response, fetch the actual resulting device state and test the affected traffic paths. But this does not address the case requirement to avoid overwriting preexisting configuration.
B:Repeated automation runs should converge on the same intended configuration without duplicate objects or accumulating drift. But this does not address the case requirement to avoid overwriting preexisting configuration.
D:Store the initiating job, device, parameters, approval, return codes and validation outcome for audit. But this does not address the case requirement to avoid overwriting preexisting configuration.
Question 893
A script replaces the entire configuration database just to add one interface description. Which safer operation fits?
- Apply only intended supported resource changes
- Use checkpoint and recovery guardrails
- Implement idempotent reconciliation
- Read and validate current state before write
Explanation
Correct Answer
A:Change only the intended resource through a supported endpoint and method. Use the documented authorized method and limited resource scope rather than broad unreviewed configuration replacement.
Incorrect Answers
B:Protect significant programmatic edits with recoverable configuration checkpoints and rollback criteria. But this does not address the case requirement to limit scope of a programmatic update.
C:Repeated automation runs should converge on the same intended configuration without duplicate objects or accumulating drift. But this does not address the case requirement to limit scope of a programmatic update.
D:Preflight observation ensures a proposed API change is required and does not overwrite a newer operator edit. But this does not address the case requirement to limit scope of a programmatic update.
Question 894
A POST call returns HTTP 200, but the expected ACL is absent on the switch. What validation remains?
- Implement idempotent reconciliation
- Read and validate current state before write
- Use checkpoint and recovery guardrails
- Verify postchange effective state
Explanation
Correct Answer
D:Re-read the effective switch config and test the intended policy. After an accepted API response, fetch the actual resulting device state and test the affected traffic paths.
Incorrect Answers
A:Repeated automation runs should converge on the same intended configuration without duplicate objects or accumulating drift. But this does not address the case requirement to verify state beyond API acknowledgement.
B:Preflight observation ensures a proposed API change is required and does not overwrite a newer operator edit. But this does not address the case requirement to verify state beyond API acknowledgement.
C:Protect significant programmatic edits with recoverable configuration checkpoints and rollback criteria. But this does not address the case requirement to verify state beyond API acknowledgement.
Question 895
A large REST change may disconnect remote administrators. What protective control should be established first?
- Read and validate current state before write
- Record authenticated change provenance
- Implement idempotent reconciliation
- Use checkpoint and recovery guardrails
Explanation
Correct Answer
D:Take a checkpoint and define supported recovery or rollback steps. Protect significant programmatic edits with recoverable configuration checkpoints and rollback criteria.
Incorrect Answers
A:Preflight observation ensures a proposed API change is required and does not overwrite a newer operator edit. But this does not address the case requirement to protect management access from irreversible changes.
B:Store the initiating job, device, parameters, approval, return codes and validation outcome for audit. But this does not address the case requirement to protect management access from irreversible changes.
C:Repeated automation runs should converge on the same intended configuration without duplicate objects or accumulating drift. But this does not address the case requirement to protect management access from irreversible changes.
Question 896
Running the same management job twice creates duplicate VLAN records and inconsistent port descriptions. What design should replace it?
- Apply only intended supported resource changes
- Use checkpoint and recovery guardrails
- Implement idempotent reconciliation
- Record authenticated change provenance
Explanation
Correct Answer
C:Make the job idempotently reconcile intended and current state. Repeated automation runs should converge on the same intended configuration without duplicate objects or accumulating drift.
Incorrect Answers
A:Use the documented authorized method and limited resource scope rather than broad unreviewed configuration replacement. But this does not address the case requirement to prevent duplicate configuration effects.
B:Protect significant programmatic edits with recoverable configuration checkpoints and rollback criteria. But this does not address the case requirement to prevent duplicate configuration effects.
D:Store the initiating job, device, parameters, approval, return codes and validation outcome for audit. But this does not address the case requirement to prevent duplicate configuration effects.
Question 897
An automated ACL deployment has no stored record of who approved the job or what HTTP responses occurred. What is needed?
- Verify postchange effective state
- Apply only intended supported resource changes
- Use checkpoint and recovery guardrails
- Record authenticated change provenance
Explanation
Correct Answer
D:Keep audited job identity, parameters, approvals and validation evidence. Store the initiating job, device, parameters, approval, return codes and validation outcome for audit.
Incorrect Answers
A:After an accepted API response, fetch the actual resulting device state and test the affected traffic paths. But this does not address the case requirement to trace programmatic changes.
B:Use the documented authorized method and limited resource scope rather than broad unreviewed configuration replacement. But this does not address the case requirement to trace programmatic changes.
C:Protect significant programmatic edits with recoverable configuration checkpoints and rollback criteria. But this does not address the case requirement to trace programmatic changes.
Question 898
A bulk job would modify ports without checking whether the desired access VLAN is already present. What safe starting point should be added?
- Use checkpoint and recovery guardrails
- Apply only intended supported resource changes
- Implement idempotent reconciliation
- Read and validate current state before write
Explanation
Correct Answer
D:Query live interface configuration before deciding whether to write. Preflight observation ensures a proposed API change is required and does not overwrite a newer operator edit.
Incorrect Answers
A:Protect significant programmatic edits with recoverable configuration checkpoints and rollback criteria. But this does not address the case requirement to apply changes only when needed.
B:Use the documented authorized method and limited resource scope rather than broad unreviewed configuration replacement. But this does not address the case requirement to apply changes only when needed.
C:Repeated automation runs should converge on the same intended configuration without duplicate objects or accumulating drift. But this does not address the case requirement to apply changes only when needed.
Question 899
A REST script claims successful group deployment but management shows stale state. What must be checked?
- Verify postchange effective state
- Implement idempotent reconciliation
- Apply only intended supported resource changes
- Record authenticated change provenance
Explanation
Correct Answer
A:Read back the intended settings from the switch and validate operation. After an accepted API response, fetch the actual resulting device state and test the affected traffic paths.
Incorrect Answers
B:Repeated automation runs should converge on the same intended configuration without duplicate objects or accumulating drift. But this does not address the case requirement to prove effective result of API update.
C:Use the documented authorized method and limited resource scope rather than broad unreviewed configuration replacement. But this does not address the case requirement to prove effective result of API update.
D:Store the initiating job, device, parameters, approval, return codes and validation outcome for audit. But this does not address the case requirement to prove effective result of API update.
