Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The agent must be in 'Aggressive' sensor mode
Why it's wrong here
Isolating works regardless of the specific sensor mode as long as it is connected.
- ✓
The agent must maintain an active connection to the Falcon Cloud
Why this is correct
Host isolation relies on the agent receiving the command from the cloud; if the host is offline, it cannot receive the instruction.
- ✗
The host must have full disk encryption disabled
Why it's wrong here
Encryption status is irrelevant to agent communication.
- ✗
The host must be in a 'Managed' group with full administrative rights
Why it's wrong here
Administrative rights are not required for the agent to isolate the host.
