CompTIA Security+ (SY0-701) — Question 362

A systems administrator needs to ensure the secure communication of sensitive data within the organization’s private cloud. Which of the following is the best choice for the administrator to implement?

Answer options

• A. IPSec
• B. SHA-1
• C. RSA
• D. TGT

Correct answer: A

Explanation

IPSec is a protocol suite designed to secure Internet Protocol (IP) communications by authenticating and encrypting each IP packet in a communication session, making it the best choice for ensuring secure communication in a private cloud. SHA-1 is a hashing algorithm, RSA is an asymmetric encryption algorithm, and TGT refers to Ticket Granting Ticket, which is unrelated to securing data communication.
