As you can see, I scored a 62/70 on the 2021 MCQ

Reviewing Questions that I missed:

Answer is B. Devices B and C must be completely cut off from each other for them to no longer communicate. Removing any three connections will not prevent devices B and C from communicating. However, if connections B-A, B-D, B-E, and B-G are removed (or C-A, C-D, C-F, and C-I), then devices B and C can no longer communicate.

Testing the new algorithm on a random sample of users will help ensure that the data gathered are from a group that is representative of all users of the application. Gathering data and perspectives from a representative sample can help the developers avoid bias.

The value of k is repeatedly decremented by 1 inside the loop until k = 0. If k is initially negative, it will continue to decrease without ever reaching 0.

Data transmitted on the Internet is broken into packets and then reassembled upon arrival. Packets may travel along different paths, arriving at the destination in order, out of order, or not at all.

An undecidable problem is one for which no algorithm can be constructed that is always capable of providing a correct yes-or-no answer. Some instances of an undecidable problem may have an algorithmic solution, but there is no algorithmic solution that could solve all instances of the problem.

Step 4 checks every element of the list, incrementing count each time target appears. Step 5 prints true if and only if count appears multiple times in the list.

In this code segment, if timer is greater than 60, bonus is assigned 1500 in the first IF block. If timer is between 30 and 60, inclusive, bonus is assigned 1000 in the second IF block. If timer is less than 30, bonus is assigned 500 in the third IF block. The correct number of bonus points is assigned to bonus for all possible values of timer.
