Dave is designing a key escrow system that needs multiple people to recover a key but does not depend on every participant being present. M of N Control type of strategy is he using.
<h3>What is key escrow in network security?</h3>
Key escrow is a form of storing necessary cryptographic keys. Each key stored in an escrow system is connected to the original user and thereafter encrypted for security purposes. Much like a valet or coat check, each key is held by the user that leverages it, and then replaced once queried.
A protection measure that requires that the lowest number of agents (M) out of the total digit of agents (N) work together to perform high-security tasks.

I would say all of the above since visiting various colleges and enquiring about their programs will definitely help to choose a college as will talking to the college advisor of your school who should know about what other colleges offer and lastly joining a club or sports team should be good networking to ask other members what they know about other colleges.
