SSCP Access Controls Practice Question
A biometric system has a high false rejection rate (FRR). Which of the following is a likely consequence?
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
✓
Legitimate users may be denied access, leading to frustration
False rejection means legitimate users are denied access, causing inconvenience. This is often a trade-off when trying to lower false acceptance rate (FAR).
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 system will require less frequent calibration
Why it's wrong here
High FRR often indicates poor calibration, not less maintenance.
- ✗
Unauthorized users are more likely to gain access
Why it's wrong here
High FRR does not increase FAR; it actually may decrease FAR if thresholds are tightened.
- ✓
Legitimate users may be denied access, leading to frustration
Why this is correct
Correct. High FRR means many false rejections.
- ✗
The system's crossover error rate (CER) will be very low
Why it's wrong here
CER is where FRR equals FAR; high FRR likely increases CER if FAR is low.
