A virus that shows up in the network environment and disrupts productivity is an example of which of the following?

A.
Vulnerability

B.
Threat

C.
Risk

D.
Exposure

Explanation:
Since a virus actually showed up, that is an exposure. If we were
calculating the possibility of a virus showing up, that would be a risk. If a virus
showed up at your network and systems got infected, you would have an exposure. Not
keeping the virus signatures up to date would be vulnerability.
