Cisco 350-201 Practice Test 71
Question 700
For an original CBRCOR educational scenario, consider: A sample changes its hash after repacking, causing analysts to discard all prior behavioral similarities despite similar network and persistence patterns. Select THREE compatible elements: a proper correction, a targeted diagnostic and an acceptance result.
- Result: The case states supported similarity with confidence levels and avoids unsupported named-actor attribution.
- Change: Use multiple structural, behavior and intelligence features to compare samples while qualifying attribution confidence.
- Check: Align endpoint, DNS, proxy and SIEM timestamps and compare candidate events to an approved workload baseline.
- Check: Compare function structure, persistence behavior, network patterns and independently sourced campaign reporting.
- Result: Extracted objects have documented provenance and uncertainty about incomplete or encrypted payloads is explicit.
- Change: Preserve the message and identity evidence, identify affected principals and sessions, revoke abuse pathways and inspect follow-on actions.
Explanation
Correct Answer
A:Hash identity is exact-file evidence while family similarity and actor attribution require corroborated, discriminating indicators. Required intervention: Use multiple structural, behavior and intelligence features to compare samples while qualifying attribution confidence.

D:Hash identity is exact-file evidence while family similarity and actor attribution require corroborated, discriminating indicators. Acceptance: The case states supported similarity with confidence levels and avoids unsupported named-actor attribution.
Incorrect Answers
C:Check: Align endpoint, DNS, proxy and SIEM timestamps and compare candidate events to an approved workload baseline. Hash identity is exact-file evidence while family similarity and actor attribution require corroborated, discriminating indicators.

Question 701
A SOC analyst is examining this cybersecurity operations situation: A HTTP session in a permitted lab capture contains a transferred executable, but analysts save only a screenshot of the URL. A proposed shortcut is: Rename random captured packet bytes as a complete executable and execute them without checking integrity. What should the SOC analyst recommend as the narrowly scoped correction? Select ONE best answer.
- Rename random captured packet bytes as a complete executable and execute them without checking integrity.
- Reconstruct authorized files or streams from packet evidence, verify completeness and hash recovered objects before isolated analysis.
- Run only authorized samples in an isolated, instrumented, disposable sandbox with egress controls and snapshot recovery.
- Preserve the message and identity evidence, identify affected principals and sessions, revoke abuse pathways and inspect follow-on actions.
Explanation
Correct Answer
B:This targeted action addresses the observed security or operational control gap without discarding necessary controls. Applied case: A HTTP session in a permitted lab capture contains a transferred executable, but analysts save only a screenshot of the URL.
Incorrect Answers
A:File extraction from network captures depends on complete protocol visibility, correct reassembly and known transfer boundaries. For this best change assessment, the shortcut changes or bypasses the necessary correctness, governance or operational boundary rather than correcting it.
C:Run only authorized samples in an isolated, instrumented, disposable sandbox with egress controls and snapshot recovery. File extraction from network captures depends on complete protocol visibility, correct reassembly and known transfer boundaries.
D:Preserve the message and identity evidence, identify affected principals and sessions, revoke abuse pathways and inspect follow-on actions. File extraction from network captures depends on complete protocol visibility, correct reassembly and known transfer boundaries.
Question 702
A Cisco cybersecurity incident response review finds: A HTTP session in a permitted lab capture contains a transferred executable, but analysts save only a screenshot of the URL. The team proposes: Reconstruct authorized files or streams from packet evidence, verify completeness and hash recovered objects before isolated analysis. Which engineering principle most strongly supports the recommended response? Select ONE best answer.
- File extraction from network captures depends on complete protocol visibility, correct reassembly and known transfer boundaries.
- Mobile intrusion visibility differs from desktop EDR; configuration profiles and identity compromise can reveal abuse when full host artifacts are unavailable.
- Constrained IoT and OT devices may require passive monitoring and safety-preserving response rather than normal workstation tooling.
- Similar network patterns can represent automated administration or compromise; session linkage and source identity determine interpretation.
Explanation
Correct Answer
A:Demonstrable success requires: Extracted objects have documented provenance and uncertainty about incomplete or encrypted payloads is explicit. Applied case: A HTTP session in a permitted lab capture contains a transferred executable, but analysts save only a screenshot of the URL.

Which evidence best tests the technical diagnosis before approving a disruptive change? Select ONE best answer.
- Match call graphs and code references to observed sandbox traces without altering the original captured file.
- Reconcile query audit, request principals, application logs, file hashes and destination transfers across a consistent timeline.
