AWS Certified Advanced Networking – Specialty (ANS-C00) — Question 115

You have two enhanced networking capable instances in a placement group. One with an Intel network interface and one with an ENA.
What network speed will be achieved between the two?

Answer options

• A. 10Gbps
• B. 20Gbps
• C. 5Gbps
• D. You cannot have different network interfaces in a placement group.

Correct answer: A

Explanation

The correct answer is A, as instances with enhanced networking can achieve up to 10Gbps when they have compatible network interfaces. Option B is incorrect because 20Gbps is not a supported speed between these two types of interfaces. Option C is wrong as 5Gbps is below the maximum capacity. Option D is false because it is possible to have different network interfaces in a placement group, as long as they support enhanced networking.
