Answer #1

Correct option is: A

Reasoning for each of the options:
A. Helps provide least privilege - by blocking all the unused ports and protocols, only the required privileges are given to the user/system (hence true)
B. Helps provide least functionality - only the unused ports and protocols are blocked, hence no functionality is restricted/blocked (hence false)
C. Streamlines the functionality of the system - it does not interfere with the functionality of the system; functionality is decided first and the restrictions are imposed thereafter (hence false)
D. Violates configuration management best practices - such restrictions are not in violation of configuration management best practices (hence false)

Please provide feedback for the answer.
