CompTIA Network+ (N10-008) — Question 799

At which of the following OSI model layers does an IMAP client run?

Answer options

• A. Layer 2
• B. Layer 4
• C. Layer 6
• D. Layer 7

Correct answer: D

Explanation

The correct answer is D, as an IMAP client operates at Layer 7, the Application layer, where user-level applications interact with network services. The other options represent different layers that deal with data transmission and connection management, which are not directly involved with the IMAP protocol.
