Designing and Implementing Microsoft Azure Networking Solutions — Question 28

You have an on-premises datacenter and an Azure subscription.

You plan to implement ExpressRoute FastPath.

You need to create an ExpressRoute gateway. The solution must minimize downtime if a single Azure datacenter fails.

Which SKU should you use?

Answer options

• A. ErGw1AZ
• B. High performance
• C. Ultra performance
• D. ErGw3AZ
• E. ErGw2AZ

Correct answer: D

Explanation

The correct choice is D, ErGw3AZ, as it is designed for high availability and redundancy, which minimizes downtime during a datacenter failure. Options A, B, C, and E do not offer the same level of resilience and performance as ErGw3AZ, making them less suitable for this requirement.
