Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Interference with radio frequency signals
Why it's wrong here
RF interference is an operational issue, not a security risk.
- ✗
Limited data storage capacity
Why it's wrong here
Storage limitation is a functional constraint, not a security risk.
- ✗
High power consumption leading to operational costs
Why it's wrong here
Power consumption is a cost issue, not a security risk.
