Refer to the exhibit. An SAP application load balancer (ALB) is configured with the CloudFormation snippet. The ALB is not distributing traffic to the EC2 instances. What is the most likely cause?

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

The target group is not associated with the load balancer

The snippet does not include a listener for the ALB. Without a listener, the ALB cannot accept traffic. The target group is defined but not associated with the ALB via a listener rule. The scheme is internet-facing, which is correct. The security group may allow traffic, but no listener exists.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • The security group does not allow inbound traffic

    Why it's wrong here

    The security group is defined but not the primary issue; no listener exists.

  • The target type is instance but the instances are not registered

    Why it's wrong here

    Instances can be registered later; without a listener, no traffic flows.

  • The target group is not associated with the load balancer

    Why this is correct

    A listener is needed to associate the target group; missing listener prevents traffic distribution.

  • The load balancer scheme is internet-facing but instances are in private subnets

    Why it's wrong here

    The scheme does not prevent traffic distribution if routing is correct.
