Question 1

A file is accessed by users in this order each day: User 1, User 2, User 1, User 3, User 2, User 1. If this pattern repeats, who is the 17th user to access the file?

Accepted Answer

User 1

Answer

The 6-access cycle repeats; 17 mod 6 = 5, which maps to position 5 in the pattern: User 2… wait—position 5 is User 2, position 1 is User 1. 17 mod 6 = 5, so the 17th access is User 2.

Question 2

In Boolean algebra, which expression is equivalent to NOT(A AND B)?

Accepted Answer

NOT A OR NOT B

Answer

De Morgan's Law states NOT(A AND B) = NOT A OR NOT B.

Question 3

Four cables—Red, Blue, Green, Yellow—are ranked by bandwidth. Red > Blue, Yellow > Green, and Blue > Yellow. What is the correct order from highest to lowest bandwidth?

Accepted Answer

Red, Blue, Yellow, Green

Answer

Chaining the given inequalities: Red > Blue > Yellow > Green.

Question 4

No encrypted files are stored on public servers. File X is stored on a public server. What can you conclude about File X?

Accepted Answer

File X is not encrypted

Answer

Since no encrypted files are on public servers and File X is on a public server, File X cannot be encrypted.

Question 5

A binary sequence follows the rule: each bit is the XOR of the two preceding bits. Starting with 1, 1, what are the next four bits?

Accepted Answer

0, 1, 1, 0

Answer

1 XOR 1=0, 1 XOR 0=1, 0 XOR 1=1, 1 XOR 1=0, giving the sequence 1,1,0,1,1,0.
