REAL EXAM QUESTIONS AND
CORRECT VERIFIED ANSWERS/
ALREADY GRADED A+ (MOST
RECENT!!)
Question 1: What is the primary advantage of using dictionaries
in Python?
A) They store data in a fixed order
B) They allow values to be associated with descriptive keys
C) They only store numeric data
D) They consume less memory than lists
Correct Answer: B
Rationale: Dictionaries store data as key-value pairs, which allows
information to be labeled in a meaningful and readable way. This
makes data retrieval efficient because values are accessed using
descriptive keys rather than numeric indexes. Dictionaries are
ideal for representing relationships such as device names and IP
addresses in automation tasks .
,Question 2: Which Python code snippet correctly demonstrates
the creation of a dictionary with key-value pairs?
A) devices = ('Router1', '192.168.1.2')
B) devices = ['Router1' = '192.168.1.2']
C) devices = {'Router1': '192.168.1.2', 'Switch2':
'10.0.0.2'}
D) devices = {'Router1', 'Switch2'}
Correct Answer: C
Rationale: A dictionary in Python uses curly braces {} with keys
and values separated by colons :. Option C correctly maps device
names to their corresponding IP addresses. Option A creates a
tuple, Option B uses incorrect syntax, and Option D creates a set .
Question 3: Which Python collection is best suited for storing an
ordered sequence of elements that can be modified?
A) Tuple
B) Set
C) List
D) Dictionary
Correct Answer: C
Rationale: Lists in Python are ordered, mutable collections that
allow modification, such as adding, removing, or changing
elements. Tuples are immutable, sets are unordered and do not
allow duplicates, and dictionaries store key-value pairs. Lists are
ideal for tasks requiring ordered, changeable data, such as
maintaining a sequence of server names in an IT automation
script .
,Question 4: What is the output when checking if the number 6
exists in the tuple (1, 2, 3, 4, 5)?
A) True
B) False
C) Error
D) None
Correct Answer: B
Rationale: The in membership operator checks if an element
exists in a tuple. Since 6 is not present in the tuple (1, 2, 3, 4,
5), the result is False. This is relevant for IT automation when
verifying if a specific value, like an IP address, exists in a
collection .
Question 5: What will be the value of the list fruits after
replacing the second element in ['apple', 'banana',
'cherry'] with 'blueberry'?
A) ['apple', 'blueberry', 'cherry']
B) ['blueberry', 'banana', 'cherry']
C) ['apple', 'banana', 'blueberry']
D) ['apple', 'blueberry', 'banana']
Correct Answer: A
Rationale: Lists are mutable, so you can modify an element by
assigning a new value to its index. The second element is at index
1 (since indexing starts at 0). fruits[1] =
'blueberry' changes 'banana' to 'blueberry', resulting
in ['apple', 'blueberry', 'cherry'] .
Question 6: Which function is used to add a single element to the
end of a list?
, A) insert()
B) append()
C) extend()
D) add()
Correct Answer: B
Rationale: The append() method adds a single item to the end
of a list, maintaining order. insert() adds at a specific
position, extend() adds multiple items from an iterable,
and add() is not a list method (it is used for sets). In IT
automation, append() is often used to build lists of results
dynamically, such as collecting system metrics .
Question 7: What does the remove() method do to a list
containing duplicates?
A) Removes all occurrences
B) Removes the first occurrence
C) Removes the last occurrence
D) Shifts elements left
Correct Answer: B
Rationale: The remove() method finds and deletes the first
matching element in a list. For duplicates, only the initial one is
affected. This is practical in automation for cleaning up redundant
entries, like removing the first duplicate hostname from a network
inventory list .
Question 8: Which method returns the index of the first
occurrence of a value in a list?
A) find()
B) index()
