Cisco 350-201 Practice Test 103
Question 1020
For an original CBRCOR educational scenario, consider: A threat feed responds 429 with a retry interval and the SOC silently drops the indicator as a negative match. Select TWO complementary steps: the targeted correction and its strongest prechange validation.
- Change: Handle asynchronous acceptance and throttling according to provider documentation, tracking final job status and deferred lookup results.
- Check: Emulate an accepted-then-failed action and a throttled lookup with Retry-After and inspect recorded states.
- Change: Use the provider-approved authentication scheme with protected headers, least-privilege token scope and redacted diagnostic logging.
- Check: Replay false-positive and confirmed malicious cases and inspect approval, timeout, cancellation and rollback outputs.
- Mark all 202 responses completed and all 429 responses benign without further investigation.
Explanation
Correct Answer
A:A 202 acknowledgment is not proof of completed execution, and 429 signals rate limiting rather than an indicator verdict. Evidence: Emulate an accepted-then-failed action and a throttled lookup with Retry-After and inspect recorded states.
B:A 202 acknowledgment is not proof of completed execution, and 429 signals rate limiting rather than an indicator verdict. Required intervention: Handle asynchronous acceptance and throttling according to provider documentation, tracking final job status and deferred lookup results.
Incorrect Answers
C:Change: Use the provider-approved authentication scheme with protected headers, least-privilege token scope and redacted diagnostic logging. A 202 acknowledgment is not proof of completed execution, and 429 signals rate limiting rather than an indicator verdict.
D:Check: Replay false-positive and confirmed malicious cases and inspect approval, timeout, cancellation and rollback outputs. A 202 acknowledgment is not proof of completed execution, and 429 signals rate limiting rather than an indicator verdict.
E:For this select two assessment, the shortcut changes or bypasses the necessary correctness, governance or operational boundary rather than correcting it. A 202 acknowledgment is not proof of completed execution, and 429 signals rate limiting rather than an indicator verdict.
Question 1021
A SOC analyst is examining this cybersecurity operations situation: A SOAR client calls response.json on a successful 204 No Content action and reports a false failure when parsing an empty body. A proposed shortcut is: Parse every HTTP response as a mandatory JSON document regardless of status or content type. What should the SOC analyst recommend as the narrowly scoped correction? Select ONE best answer.
- Validate status and media type before decoding an optional body, and follow documented headers for limits and continuation.
- Use shared versioned automation, small reviewed changes, continuous feedback, observability and repeatable recovery practices.
- Define desired collectors, roles and network policies in reviewed IaC with state, plans and idempotent convergence checks.
- Parse every HTTP response as a mandatory JSON document regardless of status or content type.
Explanation
Correct Answer
A:This targeted action addresses the observed security or operational control gap without discarding necessary controls. HTTP responses carry a status, headers and optional body; successful no-content responses need not contain JSON.
Incorrect Answers
B:Use shared versioned automation, small reviewed changes, continuous feedback, observability and repeatable recovery practices. HTTP responses carry a status, headers and optional body; successful no-content responses need not contain JSON.
C:Define desired collectors, roles and network policies in reviewed IaC with state, plans and idempotent convergence checks. HTTP responses carry a status, headers and optional body; successful no-content responses need not contain JSON.
D:HTTP responses carry a status, headers and optional body; successful no-content responses need not contain JSON. For this best change assessment, the shortcut changes or bypasses the necessary correctness, governance or operational boundary rather than correcting it.
Question 1022
A Cisco cybersecurity incident response review finds: A SOAR client calls response.json on a successful 204 No Content action and reports a false failure when parsing an empty body. The team proposes: Validate status and media type before decoding an optional body, and follow documented headers for limits and continuation. Which engineering principle most strongly supports the recommended response? Select ONE best answer.
- IaC expresses reproducible managed infrastructure and should detect drift rather than blindly duplicate or destroy existing resources.
- HTTP responses carry a status, headers and optional body; successful no-content responses need not contain JSON.
- Routine lookups are automation candidates, but uncertainty and potential business damage require explicit decision boundaries.
- Shell word splitting and working directory context can change targets even when the visible command appears harmless.
Explanation
Correct Answer
B:Demonstrable success requires: The client recognizes success without body content and retrieves all permitted paginated intelligence results. This principle explains the proposed technical approach, which is: Validate status and media type before decoding an optional body, and follow documented headers for limits and continuation.

Question 1024
A candidate correction has been tested and the platform team requires a post-change acceptance check. Original problem: A SOAR client calls response.json on a successful 204 No Content action and reports a false failure when parsing an empty body. The response owner needs positive and negative results and evidence that legitimate security and business workflows still function. Which acceptance result demonstrates correct security operations behavior without disrupting authorized workflows? Select ONE best answer.
- The workflow reduces toil without allowing uncertain classification to trigger unreviewed account or network disruption.
- Tested detection logic is deployed with traceable results and failing rules remain blocked from promotion.
- Automated routing uses evaluated confidence thresholds and uncertain high-impact actions receive analyst review.
- The client recognizes success without body content and retrieves all permitted paginated intelligence results.

Question 1025
An implementation sign-off request identifies the following problem: A SOAR client calls response.json on a successful 204 No Content action and reports a false failure when parsing an empty body. Which paired technical change and validation should close the implementation review? Select ONE best answer.
- Change: Honor documented payload limits, timeouts, idempotency and asynchronous action confirmation in automation clients. Verify: Test the supported batch threshold and a lost-response case while reconciling actual device action IDs and outcomes.
- Change: Validate required environment values, handle missing variables explicitly and prevent secret values from entering command output or shell history. Verify: Exercise missing and set variable cases while checking permissions, output paths and redacted logs.
- Change: Use a durable event identifier, bounded retry semantics and complete response traversal when modifying the incident workflow. Verify: Simulate repeated responses and multiple pages and compare ticket identifiers, unique alert counts and collected context.
- Change: Validate status and media type before decoding an optional body, and follow documented headers for limits and continuation. Verify: Inspect mock 200, 202 and 204 responses with headers and query continuation metadata for all paths.
