CompTIA Network+ (N10-008) — Question 439

A GRE tunnel has been configured between two remote sites. Which of the following features, when configured, ensures the GRE overhead does not affect payload?

Answer options

• A. Jumbo frames
• B. Auto medium-dependent interface
• C. Interface crossover
• D. Collision detection

Correct answer: A

Explanation

Jumbo frames allow for larger packet sizes, which means that the additional GRE overhead can be accommodated without impacting the actual data payload. The other options, such as auto medium-dependent interface, interface crossover, and collision detection, do not address the issue of overhead in the same way and are not relevant to managing GRE tunnel payload efficiency.
