Cisco 350-201 Practice Test 51
Question 500
For an original CBRCOR educational scenario, consider: A SIEM notes a privileged user signing in from a new browser but no associated abnormal activity or corroborating signals. Select THREE compatible elements: a proper correction, a targeted diagnostic and an acceptance result.
- Change: Tailor dashboards to stakeholder decisions using incident severity, asset exposure, response outcomes and contextual trends.
- Change: Verify alert evidence and identity ownership, prioritize based on harmful follow-on actions and invoke approved credential containment when warranted.
- Result: The report supports its behavioral labels with telemetry and separates confirmed activity from hypotheses.
- Check: Inspect MFA challenge history, session tokens, new grants, device state and the user's confirmed activity.
- Check: Test legitimate transaction flows and disallowed administrative connections from each relevant source VLAN or zone.
- Result: Confirmed account misuse is restricted and benign events are documented without unnecessary enterprise-wide lockouts.
Explanation
Correct Answer
B:Evidence: Inspect MFA challenge history, session tokens, new grants, device state and the user's confirmed activity. Applied case: A SIEM notes a privileged user signing in from a new browser but no associated abnormal activity or corroborating signals.
D:Acceptance: Confirmed account misuse is restricted and benign events are documented without unnecessary enterprise-wide lockouts.
F:Evidence: Inspect MFA challenge history, session tokens, new grants, device state and the user's confirmed activity. A user anomaly is a hypothesis; subsequent privileged actions and authentication evidence change response urgency.
Incorrect Answers
A:Change: Tailor dashboards to stakeholder decisions using incident severity, asset exposure, response outcomes and contextual trends. A user anomaly is a hypothesis; subsequent privileged actions and authentication evidence change response urgency.
C:Result: The report supports its behavioral labels with telemetry and separates confirmed activity from hypotheses. A user anomaly is a hypothesis; subsequent privileged actions and authentication evidence change response urgency.
E:Check: Test legitimate transaction flows and disallowed administrative connections from each relevant source VLAN or zone. A user anomaly is a hypothesis; subsequent privileged actions and authentication evidence change response urgency.
Question 501
A SOC analyst is examining this cybersecurity operations situation: A responder wants to inspect malicious HTTP request contents but has only NetFlow summaries and assumes those summaries include complete payloads. A proposed shortcut is: Claim that a five-tuple flow record contains decrypted application data and every packet on the enterprise network. What should the SOC analyst recommend as the narrowly scoped correction? Select ONE best answer.
- Claim that a five-tuple flow record contains decrypted application data and every packet on the enterprise network.
- Map observed adversary behaviors to relevant ATT&CK tactics and techniques with evidence and avoid asserting unsupported attribution.
- Choose flow, logs or packet capture based on required fields, sensor placement, sampling and encryption limitations.
- Build, scan and sign or approve hardened golden images before deployment, then replace noncompliant instances from the trusted baseline.
Explanation
Correct Answer
C:This targeted action addresses the observed security or operational control gap without discarding necessary controls. Applied case: A responder wants to inspect malicious HTTP request contents but has only NetFlow summaries and assumes those summaries include complete payloads.
Incorrect Answers
A:Flow records summarize connections while full capture can preserve protocol packets only where visibility and collection policy permit. For this best change assessment, the shortcut changes or bypasses the necessary correctness, governance or operational boundary rather than correcting it.
B:Map observed adversary behaviors to relevant ATT&CK tactics and techniques with evidence and avoid asserting unsupported attribution. Flow records summarize connections while full capture can preserve protocol packets only where visibility and collection policy permit.
D:This option addresses a different security operations topic (Golden machine image hardening) rather than the documented Network analysis capture and visibility limits decision.
Question 502
A Cisco cybersecurity incident response review finds: A responder wants to inspect malicious HTTP request contents but has only NetFlow summaries and assumes those summaries include complete payloads. The team proposes: Choose flow, logs or packet capture based on required fields, sensor placement, sampling and encryption limitations. Which engineering principle most strongly supports the recommended response? Select ONE best answer.
- Hardening guidance is platform and workload specific; a relevant benchmark needs a tested applicability and exception review.
- A SIEM can correlate only what its collectors and parsers accurately ingest; incorrect fields create false investigative conclusions.
- Tuning should reduce unhelpful alerts without suppressing essential attack patterns or expanding policy exceptions beyond their cause.
- Flow records summarize connections while full capture can preserve protocol packets only where visibility and collection policy permit.
Explanation
Correct Answer
D:Demonstrable success requires: The investigation states which observed fields are reliable and where encrypted or unsampled traffic remains unknown. Applied case: A responder wants to inspect malicious HTTP request contents but has only NetFlow summaries and assumes those summaries include complete payloads.
Incorrect Answers
A:Hardening guidance is platform and workload specific; a relevant benchmark needs a tested applicability and exception review. Flow records summarize connections while full capture can preserve protocol packets only where visibility and collection policy permit.
