CompTIA A+ 220-801

Answer: A - The boss instructing the technician to restrict access to the PC and wait for the boss to arrive is an example of Chain of custody.

Key Takeaway - Chain of custody ensures proper documentation is made throughout a security investigation and that the evidence has not been tampered. Since the technician has contacted her boss in the first place, the technician has already responded to the incident by following the appropriate chain of custody. It is likely the PC technician would also be asked to document everything they found as well, and although this may be implied in the situation above, chain of custody is a stronger answer choice.
