FC0-U71 Security Practice Question
A warehouse supervisor reports that an unknown person wearing a delivery uniform walked through the open loading dock, entered the server room, and left with a backup drive. The company wants to prevent unauthorized entry into the server room without rebuilding the entire facility. Which control should be implemented FIRST?
⚠ Common exam trap
The trap here is choosing a monitoring or awareness tool, which detects or discourages, instead of a preventive access control that physically stops the unauthorized entry.
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
✓
Install an electronic badge reader on the server room door that logs each entry attempt
The incident shows an outsider reaching a restricted area through an uncontrolled opening, so the first fix must prevent unauthorized entry at that boundary. A badge reader on the server room door authenticates individuals and logs attempts, directly addressing the gap. A SIEM, awareness training, and drive encryption are valuable but do not stop someone from walking in and carrying equipment out.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Deploy a security information and event management (SIEM) platform to correlate logs
Why it's wrong here
A SIEM aggregates and analyzes log data to detect patterns, but it is a detective and monitoring tool, not a barrier. Even with perfect correlation, an intruder could still walk through the door and remove hardware. It also depends on log sources that may not yet exist, so it does not directly prevent the unauthorized entry described.
- ✓
Install an electronic badge reader on the server room door that logs each entry attempt
Why this is correct
A badge reader enforces authentication at the specific point of weakness: the server room door. Only staff with valid badges can enter, and the audit log records who attempted access and when. This directly stops the walk-in intrusion described while also providing accountability, making it the most targeted and immediate fix.
- ✗
Encrypt the backup drives stored in the server room
Why it's wrong here
Encryption protects the confidentiality of data if a drive is stolen, so it reduces the impact of the theft but does not stop the unauthorized person from entering and removing hardware. The requirement is to prevent unauthorized entry, which encryption cannot do; it is a complementary safeguard rather than the first control to apply.
- ✗
Provide security awareness training to all warehouse employees
Why it's wrong here
Awareness training helps employees recognize and report suspicious behavior, which has value, but it does not physically stop an outsider from opening a door and taking equipment. The scenario involves an unknown person entering a restricted area, so a preventive access control is needed first; training alone leaves the server room just as exposed.
