Q7Network Management and Operation
A company hosts an application on Amazon EC2 instances behind a Network Load Balancer (NLB). To increase application availability, a solutions architect added EC2 instances in a second Availability Zone and added those instances to the NLB target group. The company’s operations team observes that traffic is routed only to the instances in the first Availability Zone. What is the **MOST operationally efficient** solution to resolve this problem?

The Network Load Balancer (NLB) needs to be configured to recognize and utilize the new Availability Zone. By enabling the new Availability Zone on the NLB, the load balancer will start distributing traffic to instances in both Availability Zones, providing improved availability and load balancing.
Option B suggests creating a new NLB, which is not necessary in this scenario. NLBs are designed to distribute traffic across instances in multiple Availability Zones, and adding the new Availability Zone to the existing NLB is the appropriate step.
Options C and D are not directly addressing the issue. Enabling proxy protocol (Option C) is useful for passing client information to the backend servers, but it doesn't resolve the issue of traffic not being routed to instances in the second Availability Zone. Creating a new target group (Option D) might be necessary for specific use cases, but it doesn't directly address the problem in this context.

Correct Answer is - A. Please refer to the extracted text from the link shared -
"You can't disable Availability Zones for a Network Load Balancer after you create it, but you can enable additional Availability Zones."
