Cisco 350-201 Practice Test 42
Question 410
For an original CBRCOR educational scenario, consider: A SaaS tenant permits copying personally identifiable information into an unmanaged cloud application without classification checks. Select TWO complementary steps: the targeted correction and its strongest prechange validation.
- Check: Test public versus restricted sharing, sensitivity labels, audit events and approved exceptions in a representative SaaS workspace.
- Change: Apply cloud and application DLP policies to sharing permissions, sensitive-content detection and sanctioned app activity.
- Disable attachment scanning and assume employee warnings are sufficient to prevent public SaaS file sharing.
- Change: Normalize time and source fields, maintain collection health and enforce documented retention and access controls by data class.
- Check: Inspect MFA challenge history, session tokens, new grants, device state and the user's confirmed activity.
Explanation
Correct Answer
A:Cloud data loss can occur through application links and APIs even when network perimeter monitoring sees no email attachment. Acceptance: Sensitive documents cannot be anonymously distributed while authorized collaboration remains intact.
B:Cloud data loss can occur through application links and APIs even when network perimeter monitoring sees no email attachment. Evidence: Test public versus restricted sharing, sensitivity labels, audit events and approved exceptions in a representative SaaS workspace.
Incorrect Answers
C:For this select two assessment, the shortcut changes or bypasses the necessary correctness, governance or operational boundary rather than correcting it. Cloud data loss can occur through application links and APIs even when network perimeter monitoring sees no email attachment.
D:Change: Normalize time and source fields, maintain collection health and enforce documented retention and access controls by data class. Cloud data loss can occur through application links and APIs even when network perimeter monitoring sees no email attachment.
E:Check: Inspect MFA challenge history, session tokens, new grants, device state and the user's confirmed activity. A SaaS tenant permits copying personally identifiable information into an unmanaged cloud application without classification checks.
Question 411
A SOC analyst is examining this cybersecurity operations situation: A noisy IDS signature fires on approved vulnerability scans but the analyst proposes disabling the entire intrusion-detection policy. A proposed shortcut is: Replace targeted threshold tuning with a blanket disablement of all high-severity network detections. What should the SOC analyst recommend as the narrowly scoped correction? Select ONE best answer.
- Replace targeted threshold tuning with a blanket disablement of all high-severity network detections.
- Enforce explicit network-zone boundaries with least-privilege intersegment policies and monitor permitted application flows.
- Add automated dependency and image scanning, protected credentials, artifact provenance and approval checks before production promotion.
- Tune specific signatures, thresholds and scoped allowlists using known benign workloads and preserved malicious test coverage.
Explanation
Correct Answer
D:This targeted action addresses the observed security or operational control gap without discarding necessary controls. Applied case: A noisy IDS signature fires on approved vulnerability scans but the analyst proposes disabling the entire intrusion-detection policy.
Incorrect Answers
A:Tuning should reduce unhelpful alerts without suppressing essential attack patterns or expanding policy exceptions beyond their cause. For this best change assessment, the shortcut changes or bypasses the necessary correctness, governance or operational boundary rather than correcting it.
B:Enforce explicit network-zone boundaries with least-privilege intersegment policies and monitor permitted application flows. Tuning should reduce unhelpful alerts without suppressing essential attack patterns or expanding policy exceptions beyond their cause.
C:Add automated dependency and image scanning, protected credentials, artifact provenance and approval checks before production promotion. Tuning should reduce unhelpful alerts without suppressing essential attack patterns or expanding policy exceptions beyond their cause.
Question 412
A Cisco cybersecurity incident response review finds: A noisy IDS signature fires on approved vulnerability scans but the analyst proposes disabling the entire intrusion-detection policy. The team proposes: Tune specific signatures, thresholds and scoped allowlists using known benign workloads and preserved malicious test coverage. Which engineering principle most strongly supports the recommended response? Select ONE best answer.
- Compensating controls can reduce a specific residual risk but do not eliminate the need to understand and govern the original deficiency.
- Tuning should reduce unhelpful alerts without suppressing essential attack patterns or expanding policy exceptions beyond their cause.
- DNS and TLS metadata support behavioral hypotheses but cannot by themselves reveal encrypted application contents or prove compromise.
- Immutable image pipelines propagate security updates consistently; patching only live instances leaves future launches vulnerable.
Explanation
Correct Answer
B:Demonstrable success requires: False positives decline while validated attack detections and evidence quality remain acceptable. Applied case: A noisy IDS signature fires on approved vulnerability scans but the analyst proposes disabling the entire intrusion-detection policy.

Question 414
A candidate correction has been tested and the platform team requires a post-change acceptance check. Original problem: A noisy IDS signature fires on approved vulnerability scans but the analyst proposes disabling the entire intrusion-detection policy. 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.
- High-confidence current indicators receive proportionate treatment while stale or untrusted feed entries are reviewed.
- Unauthorized paths are denied and each crucial control action leaves sufficient forensic evidence.
