Cisco 350-201 Practice Test 26
Question 250
For an original CBRCOR educational scenario, consider: A cloud team manually patches one running instance while its immutable image template still contains an exposed administrative service. Select TWO complementary steps: the targeted correction and its strongest prechange validation.
- Check: Compare source image digest, package scan, approved baseline and a fresh deployment against the operational policy.
- Change: Build, scan and sign or approve hardened golden images before deployment, then replace noncompliant instances from the trusted baseline.
- Change: Validate source onboarding, field mapping, time parsing and health before using normalized events in production detection content.
- Rely on one manually fixed server while continuing to scale hundreds of systems from the compromised template.
- Check: Reproduce authorized and restricted USB and print operations with test documents and inspect enforcement events.
Explanation
Correct Answer
A:Immutable image pipelines propagate security updates consistently; patching only live instances leaves future launches vulnerable. Acceptance: Newly launched instances consistently meet the reviewed security baseline and can be traced to an approved image revision.
B:Immutable image pipelines propagate security updates consistently; patching only live instances leaves future launches vulnerable. Evidence: Compare source image digest, package scan, approved baseline and a fresh deployment against the operational policy.
Incorrect Answers
C:Change: Validate source onboarding, field mapping, time parsing and health before using normalized events in production detection content. Immutable image pipelines propagate security updates consistently; patching only live instances leaves future launches vulnerable.
D:For this select two assessment, the shortcut changes or bypasses the necessary correctness, governance or operational boundary rather than correcting it. Immutable image pipelines propagate security updates consistently; patching only live instances leaves future launches vulnerable.
E:Check: Reproduce authorized and restricted USB and print operations with test documents and inspect enforcement events. Immutable image pipelines propagate security updates consistently; patching only live instances leaves future launches vulnerable.
Question 251
A SOC analyst is examining this cybersecurity operations situation: An endpoint inventory marks a server compliant although it is exposed to the internet and has no EDR sensor reporting health. A proposed shortcut is: Declare unobserved assets secure solely because the SIEM has never received an event from them. What should the SOC analyst recommend as the narrowly scoped correction? Select ONE best answer.
- Declare unobserved assets secure solely because the SIEM has never received an event from them.
- Normalize time and source fields, maintain collection health and enforce documented retention and access controls by data class.
- Reconcile authoritative asset inventory, ownership, supported vulnerability scanning, configuration and sensor coverage before assigning posture.
- Test controls against the complete attacker path and add missing segmentation or identity telemetry at the observed gap.
Explanation
Correct Answer
C:This targeted action addresses the observed security or operational control gap without discarding necessary controls. Asset posture depends on exposure, controls and observed state; the absence of an alert is not evidence of compliance.
Incorrect Answers
A:Asset posture depends on exposure, controls and observed state; the absence of an alert is not evidence of compliance. For this best change assessment, the shortcut changes or bypasses the necessary correctness, governance or operational boundary rather than correcting it.
B:Normalize time and source fields, maintain collection health and enforce documented retention and access controls by data class. Asset posture depends on exposure, controls and observed state; the absence of an alert is not evidence of compliance.

Question 252
A Cisco cybersecurity incident response review finds: An endpoint inventory marks a server compliant although it is exposed to the internet and has no EDR sensor reporting health. The team proposes: Reconcile authoritative asset inventory, ownership, supported vulnerability scanning, configuration and sensor coverage before assigning posture. Which engineering principle most strongly supports the recommended response? Select ONE best answer.
- AI can prioritize likely relationships but indicator matching and attribution require independently corroborated evidence.
- Cloud data loss can occur through application links and APIs even when network perimeter monitoring sees no email attachment.
- Asset posture depends on exposure, controls and observed state; the absence of an alert is not evidence of compliance.
- TCP transport artifacts distinguish failed connectivity and loss from application-layer requests or multiple unique payload transfers.
Explanation
Correct Answer
C:Relevant validation before approval: Cross-check discovery records, network reachability, patch inventory and security agent last-seen timestamps. Demonstrable success requires: Every critical asset has a current owner and defensible posture measurement with known visibility gaps.

Question 254
A candidate correction has been tested and the platform team requires a post-change acceptance check. Original problem: An endpoint inventory marks a server compliant although it is exposed to the internet and has no EDR sensor reporting health. 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.
- Every critical asset has a current owner and defensible posture measurement with known visibility gaps.
- Supported cases proceed efficiently while uncertain or disruptive actions await appropriate authorization.
- Escalated matches have a reproducible evidence trail and unconfirmed associations remain investigatory leads.
- Authorized applications communicate while untrusted devices cannot inherit unrestricted access merely from network proximity.

Question 255
An implementation sign-off request identifies the following problem: An endpoint inventory marks a server compliant although it is exposed to the internet and has no EDR sensor reporting health. Which paired technical change and validation should close the implementation review? Select ONE best answer.
- Change: Constrain exceptions by identity, source, time and monitoring, and schedule removal or replacement at an accountable review date. Verify: Review exception approval, constrained reachability, logs and expiry in a controlled negative and positive access test.
- Change: Use AI-generated prioritization as a decision aid and require cited underlying events and human review before high-impact containment. Verify: Compare the model explanation, supporting log timestamps and labeled benign or malicious cases before acting.
- Change: Test controls against the complete attacker path and add missing segmentation or identity telemetry at the observed gap. Verify: Simulate permitted and denied flows plus authorized privilege grants in a lab and compare expected logs and enforcement results.
- Change: Reconcile authoritative asset inventory, ownership, supported vulnerability scanning, configuration and sensor coverage before assigning posture. Verify: Cross-check discovery records, network reachability, patch inventory and security agent last-seen timestamps.
