CND Endpoint Protection Practice Question
An organization's security team is deploying an EDR agent across corporate endpoints. During testing, the agent's kernel-mode driver causes a Blue Screen of Death (BSOD) during boot on systems running a third-party disk encryption filter driver. Which administrative action should be taken first to isolate and remediate the driver conflict?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Boot into Safe Mode and adjust the EDR driver start type or use sensor configuration exclusions
Booting into Safe Mode or using the EDR management console to temporarily disable specific sensor modules (such as kernel process or file monitoring) allows isolation of the conflicting component.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Uninstall the third-party disk encryption driver permanently
Why it's wrong here
Removing disk encryption violates enterprise compliance and security baselines.
- ✓
Boot into Safe Mode and adjust the EDR driver start type or use sensor configuration exclusions
Why this is correct
Safe Mode allows administrative intervention to modify driver configurations or apply vendor-provided workarounds/exclusions.
- ✗
Reinstall the Windows operating system with a clean image
Why it's wrong here
Reimaging is a drastic and unnecessary troubleshooting step for a software driver conflict.
- ✗
Disable Secure Boot in UEFI settings
Why it's wrong here
Disabling Secure Boot lowers endpoint security posture and does not resolve kernel-level filter driver order clashes.
