A is the correct answer, Need to enable new AZ into NLB.
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.
