Cisco 350-201 Practice Test 84
Question 830
For an original CBRCOR educational scenario, consider: An EDR rule built from a sample's temporary directory name alerts on every approved software installer and overwhelms triage. Select TWO complementary steps: the targeted correction and its strongest prechange validation.
- Check: Replay representative benign installer traces and malicious test artifacts and compare true and false matches.
- Check: Compare scan findings, actual versions, ticket due dates, firewall test results and exception approval records.
- Promote any unreviewed wildcard extracted from malware into a global block rule with no false-positive testing.
- Change: Compare service health, source distribution, protocol anomalies and traffic baseline before classifying and escalating availability events.
- Change: Validate complex indicators against benign reference telemetry and scope them with specific process, path or network context.
Explanation
Correct Answer
A:Required intervention: Validate complex indicators against benign reference telemetry and scope them with specific process, path or network context.
E:Evidence: Replay representative benign installer traces and malicious test artifacts and compare true and false matches.
Incorrect Answers
B:Check: Compare scan findings, actual versions, ticket due dates, firewall test results and exception approval records. Complex signatures need both malicious coverage and false-positive evaluation before production deployment.
C:For this select two assessment, the shortcut changes or bypasses the necessary correctness, governance or operational boundary rather than correcting it. Complex signatures need both malicious coverage and false-positive evaluation before production deployment.
D:Change: Compare service health, source distribution, protocol anomalies and traffic baseline before classifying and escalating availability events. Complex signatures need both malicious coverage and false-positive evaluation before production deployment.
Question 831
A SOC analyst is examining this cybersecurity operations situation: An access-key credential is used to read thousands of sensitive cloud object files from an unrecognized network shortly after a role change. A proposed shortcut is: Assume every public bucket object was definitely copied, then delete audit logs before preserving access evidence. What should the SOC analyst recommend as the narrowly scoped correction? Select ONE best answer.
- Use multiple structural, behavior and intelligence features to compare samples while qualifying attribution confidence.
- Produce a concise defensive summary with observed behavior, confidence, hashes, infrastructure context and detection or containment guidance.
- Correlate cloud audit, identity, object sensitivity and network activity to define exposure and revoke unauthorized access.
- Assume every public bucket object was definitely copied, then delete audit logs before preserving access evidence.
Explanation
Correct Answer
C:This targeted action addresses the observed security or operational control gap without discarding necessary controls. Data exposure requires both effective permissions and observed access paths; a public setting alone does not prove every file was downloaded.
Incorrect Answers
A:Use multiple structural, behavior and intelligence features to compare samples while qualifying attribution confidence. Data exposure requires both effective permissions and observed access paths; a public setting alone does not prove every file was downloaded.
B:Produce a concise defensive summary with observed behavior, confidence, hashes, infrastructure context and detection or containment guidance. Data exposure requires both effective permissions and observed access paths; a public setting alone does not prove every file was downloaded.
D:Data exposure requires both effective permissions and observed access paths; a public setting alone does not prove every file was downloaded. For this best change assessment, the shortcut changes or bypasses the necessary correctness, governance or operational boundary rather than correcting it.
Question 832
A Cisco cybersecurity incident response review finds: An access-key credential is used to read thousands of sensitive cloud object files from an unrecognized network shortly after a role change. The team proposes: Correlate cloud audit, identity, object sensitivity and network activity to define exposure and revoke unauthorized access. Which engineering principle most strongly supports the recommended response? Select ONE best answer.
- Threat models connect assets, actors, entry points and boundaries to plausible failure or abuse scenarios rather than treating all components equally.
- Forensic reproducibility depends on preserving the original artifact and recording who accessed derived samples.
- A base severity score is general technical guidance; operational risk changes with environment, threat activity and system consequence.
- Data exposure requires both effective permissions and observed access paths; a public setting alone does not prove every file was downloaded.
Explanation
Correct Answer
D:Demonstrable success requires: Incident owners can report confirmed versus potential exposed objects and verify unauthorized reads are prevented. This principle explains the proposed technical approach, which is: Correlate cloud audit, identity, object sensitivity and network activity to define exposure and revoke unauthorized access.
Incorrect Answers
A:This option addresses a different security operations topic (Threat modeling assets and trust boundaries) rather than the documented Cloud object storage suspected data loss decision.
B:Forensic reproducibility depends on preserving the original artifact and recording who accessed derived samples. Data exposure requires both effective permissions and observed access paths; a public setting alone does not prove every file was downloaded.
C:A base severity score is general technical guidance; operational risk changes with environment, threat activity and system consequence. Data exposure requires both effective permissions and observed access paths; a public setting alone does not prove every file was downloaded.
