Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Rebuilding the physical data center facility electrical grid
Why it's wrong here
Facility power management is outside the scope of Cortex XDR incident response.
- ✓
Isolating the compromised endpoint from the network
Why this is correct
Host isolation stops lateral movement from a compromised machine.
- ✓
Disabling or forcing password resets for the compromised user account
Why this is correct
Account remediation actions stop active session hijacking and further unauthorized access.
- ✓
Quarantining malicious credential-dumping tools found on endpoints
Why this is correct
Quarantine stops tools like Mimikatz from running on endpoints.
- ✗
Upgrading the BIOS firmware on enterprise routers
Why it's wrong here
Router firmware updates are handled via network management tools, not ITDR response actions.
