AWS Certified SysOps Administrator – Associate — Question 316

A company is running an application on a group of Amazon EC2 instances behind an Application Load Balancer. The EC2 instances run across three Availability Zones. The company needs to provide the customers with a maximum of two static IP addresses for their applications.

How should a SysOps administrator meet these requirement?

Answer options

• A. Add AWS Global Accelerator in front of the Application Load Balancer.
• B. Add an internal Network Load Balancer behind the Application Load Balancer.
• C. Configure the Application Load Balancer in only two Availability Zones.
• D. Create two Elastic IP addresses and assign them to the Application Load Balancer.

Correct answer: A

Explanation

AWS Global Accelerator provides two static IP addresses that act as a fixed entry point to your application endpoints, such as an Application Load Balancer. Application Load Balancers themselves do not support static IP addresses directly, and associating Elastic IPs directly to them is not supported. Placing an internal Network Load Balancer behind an ALB does not expose public-facing static IPs to the customers.
