2. A system administrator wants to store multiple server names in a single variable. Which
data type is most appropriate?
A. Integer
B. List
C. Float
D. Boolean
Correct Answer: B. List
Rationale:
A list allows multiple values to be stored in a single variable and supports indexing and iteration.
3. Which operator is used to compare equality in Python?
A. =
B. !=
C. ==
D. >=
,Correct Answer: C. ==
Rationale:
The double equals operator checks whether two values are equal, while a single equals sign

4. Which file mode allows both reading and writing without deleting existing content?
A. r+
B. w
C. a
D. x
Correct Answer: A. r+
Rationale:
The r+ mode opens a file for reading and writing while preserving existing file contents.
5. What is the output type of the input() function in Python?

Correct Answer: C. Improve readability
Rationale:
Comments explain code functionality and improve maintainability for developers and
administrators.
, 11. Which symbol begins a single-line comment in Python?
A. //
B. #
C. <!--
D. **
Correct Answer: B. #
Rationale:
Python uses the hash symbol to create comments ignored during execution.
12. Which function converts a string into an integer?
A. str()
B. float()
C. bool()
D. int()
Correct Answer: D. int()
Rationale:
The int() function converts compatible string values into integers.
13. A network automation script repeatedly checks device status until connectivity is
