Exam SY0-701 topic 1 question 323 discussion

A. IPSec. IPSec (Internet Protocol Security) is a suite of protocols designed specifically to secure IP communications by authenticating and encrypting each IP packet in a communication session. It’s widely used to protect data in transit—making it ideal for securing sensitive communications within a private cloud environment. Let’s break down the others: - B. SHA-1 is a hashing algorithm, not an encryption or communication protocol—and it's considered weak and deprecated. - C. RSA is an encryption algorithm used for secure key exchange, but it’s not a complete communication protocol on its own. - D. TGT (Ticket Granting Ticket) is part of Kerberos authentication, which helps with identity verification but doesn’t secure data transmission directly

The answer is A. IPSec (Internet Protocol Security) is a suite of protocols used to secure Internet Protocol (IP) communications. It authenticates and encrypts each IP packet in a communication session, providing confidentiality, data integrity, and authentication. It is commonly used for creating secure Virtual Private Networks (VPNs) and is ideal for securing communication in a private cloud.
