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 server is offline.
Why it's wrong here
The 'Effective Access' tool evaluates permissions based on the security descriptor, not server availability.
- ✓
An explicit Deny entry is present.
Why this is correct
Explicit Deny entries in Windows ACLs take precedence over Allow permissions.
- ✗
The drive is full.
Why it's wrong here
Disk space does not impact permission evaluation.
- ✗
They are not in the correct group.
Why it's wrong here
Even if they were in the group, the 'Deny' would still block access.
