D522 Exam Question with Verified Correct
Answers
write()
Which function should be used to add data to a file, such as a network configuration file?
To define a function with a default greeting
Based on the Python code snippet:
def greet(name, greeting = "Welcome to WGU"):
return f"{greeting}, {name}!"
What is the purpose of the first line of code?
Add a colon after def multiply_numbers(num1, num2).
This Python code snippet returns a syntax error when run:
def multiply_numbers(num1, num2)
result = num1 * num2
return result
num1 = 5
num2 = 8
print(multiply_numbers(num1, num2))
Which code adjustment will resolve the syntax error?
,List
Based on the Python snippet:
devices = ["router01", "switch01", "modem01", "gateway01", "printer01"]
Which data structure is being used to store the names for various types of devices within
devices?
Converts the user's input into an integer and sums it
Based on the Python snippet:
value = input("Enter a number: ")
result = int(value) + 10
print(result)
What purpose does result = int(value) + 10 serve?
Decrease the indentation of the else statement.
This Python snippet checks the new processing speed of an updated computer. However, the
snippet throws an error when ran.
def check_processing_speed(current_speed, threshold_speed):
is_fast_processing = current_speed > threshold_speed
if is_fast_processing:
print(f"The processing speed of {current_speed} GHz is fast.")
else:
, print(f"The processing speed of {current_speed} GHz is not fast enough. Consider an
upgrade.")
current_speed = 4
threshold_speed = 2
check_processing_speed(current_speed, threshold_speed)
Which code adjustment will provide the intended response by addressing the error?
Tuple
A developer is creating a Python script to capture metrics for different network interfaces on
a router, with each set of metrics treated as a single, immutable record. The stored record will
represent a snapshot of metrics for a specific network interface at a given point in time to
capture historical records for future analysis.
Which data structure should be used to store the recorded metrics based on the specifications?
numbers[3]
Based on the Python list:
numbers = [10, 20, 30, 40]
What is the index position of the element "40"?
Ordered and unchangeable
Which characteristics are associated with tuples in Python?
