At which layer of the OSI model does error checking occur with IPv6?

Answer options

• A. Layer 2
• B. Layer 3
• C. Layer 4
• D. Layer 7

Correct answer: C

Explanation

Error checking for IPv6 happens at Layer 4, which is the transport layer. This layer is responsible for error detection and correction, ensuring reliable data transmission. The other layers, such as Layer 2 (data link), Layer 3 (network), and Layer 7 (application), do not handle error checking for IPv6.
