Cisco 350-201 Practice Test 77
Question 760
For an original CBRCOR educational scenario, consider: A mobile user reports repeated unauthorized account prompts while MDM inventory says the device stopped checking in days ago. Select TWO complementary steps: the targeted correction and its strongest prechange validation.
- Change: Correlate process trees, file writes, registry or task persistence and outbound activity during isolated behavioral observation.
- Change: Correlate mobile device management posture, installed profiles, app provenance, identity logins and available mobile telemetry.
- Check: Compare repeated sandbox runs, host artifacts, DNS requests and source-event timestamps under controlled isolation.
- Check: Review MDM compliance, profile installation, app permissions, OS version and correlated cloud sign-ins.
- Assume a mobile phone is unhackable and close every case because it lacks a traditional Windows process tree.
Explanation
Correct Answer
B:Mobile intrusion visibility differs from desktop EDR; configuration profiles and identity compromise can reveal abuse when full host artifacts are unavailable. Acceptance: Unauthorized enrollment or grants are revoked with preserved evidence and supported device remediation.
D:Mobile intrusion visibility differs from desktop EDR; configuration profiles and identity compromise can reveal abuse when full host artifacts are unavailable. Required intervention: Correlate mobile device management posture, installed profiles, app provenance, identity logins and available mobile telemetry.
Incorrect Answers
A:Change: Correlate process trees, file writes, registry or task persistence and outbound activity during isolated behavioral observation. Mobile intrusion visibility differs from desktop EDR; configuration profiles and identity compromise can reveal abuse when full host artifacts are unavailable.
C:Check: Compare repeated sandbox runs, host artifacts, DNS requests and source-event timestamps under controlled isolation. Mobile intrusion visibility differs from desktop EDR; configuration profiles and identity compromise can reveal abuse when full host artifacts are unavailable.
E:For this select two assessment, the shortcut changes or bypasses the necessary correctness, governance or operational boundary rather than correcting it.

Question 761
A SOC analyst is examining this cybersecurity operations situation: A building controller unexpectedly connects to an external address after a firmware change, yet it cannot safely run standard EDR software. A proposed shortcut is: Install unsupported desktop security agents or reboot safety-critical devices without operational coordination. What should the SOC analyst recommend as the narrowly scoped correction? Select ONE best answer.
- Install unsupported desktop security agents or reboot safety-critical devices without operational coordination.
