CompTIA Network+ (N10-006) — Question 14

Which of the following integrity security mechanisms ensures that a sent message has been received intact, by the intended receiver?

Answer options

• A. IPSEC
• B. SHA
• C. DES
• D. CRC

Correct answer: A

Explanation

The correct answer is A, IPSEC, as it provides integrity by ensuring that the data has not been altered during transmission. The other options, while related to security, do not specifically focus on the integrity of the message in the same way; SHA is a hashing algorithm, DES is an encryption standard, and CRC is a method for error-checking but does not offer the same level of security as IPSEC.
