WGU Foundations of Computer Science Sample Questions (Q48-Q53):

NEW QUESTION # 48
Which protocol provides encryption while email messages are in transit?

A. TLS
B. HTTP
C. IMAP
D. FTP

Answer: A

Explanation:
"Encryption in transit" means protecting data while it moves across a network so that eavesdroppers cannot read or modify it. For email systems, this protection is most commonly provided byTLS (Transport Layer Security). TLS is a cryptographic protocol that can wrap application protocols (including mail protocols) to provide confidentiality, integrity, and server (and sometimes client) authentication. In practice, TLS is used to secure connections such as SMTP submission (often with STARTTLS or implicit TLS), IMAP over TLS, and POP3 over TLS. Textbooks present TLS as the standard successor to SSL and the foundation of secure communication on the modern Internet.
The other options are not correct in this context. FTP is a file transfer protocol and is traditionally unencrypted unless paired with additional security mechanisms (e.g., FTPS, which uses TLS, or SFTP, which uses SSH). HTTP is a web protocol; it becomes encrypted only when used as HTTPS, which again relies on TLS underneath. IMAP is an email retrieval protocol, butIMAP itself is not the encryption protocol- IMAP can be run over TLS (IMAPS) to become secure.
Therefore, the protocol that provides encryption while email messages (or email protocol traffic) are in transit is TLS.

NEW QUESTION # 49
What is the correct way to represent a boolean value in Python?

A. True
B. "true"
C. true
D. "True"

Answer: A

Explanation:
Python has a built-in boolean type named bool, which has exactly two values: True and False. These are language keywords/constants and are case-sensitive. Therefore, the correct representation of a boolean value is True (capital T, lowercase rest) or False (capital F). This is consistently taught in introductory programming textbooks because it affects conditional statements (if, while), logical operations (and, or, not), and comparisons.
Option A, "True", is a string literal, not a boolean. While it visually resembles the boolean constant, it behaves differently: non-empty strings are "truthy" in conditions, but "True" == True is false because they are different types (str vs bool). Option B, "true", is also a string, and it differs in casing as well. Option D, true, is not valid in Python; it will raise a NameError unless a variable named true has been defined.
Textbooks also stress that boolean values often result from comparisons, such as x > 0, and that booleans are a subtype of integers in Python (True behaves like 1 and False like 0 in arithmetic contexts). Still, their primary use is representing logical truth values for control flow and decision- making.

NEW QUESTION # 50
What is the time complexity of a quicksort algorithm?

A. O(log n)
B. O(n)
C. O(n log n)
D. O(1)

Answer: C

Explanation:
Quicksort is a divide-and-conquer sorting algorithm. It works by selecting a pivot element, partitioning the array into two subarrays (elements less than the pivot and elements greater than the pivot), and then recursively sorting those subarrays. In the average case, the partition step splits the array into roughly equal halves, so the recurrence is commonly written as (T(n) = T(n/2) + T(n/2) + O(n)), where (O(n)) is the cost of partitioning. This solves to (O(n \log n)), which is why quicksort is widely taught as an efficient general- purpose sorting method.
However, textbooks also emphasize that quicksort has a worst-case time complexity of (O(n
