False Information about AWS Load Balancers

Answer - A.

The AWS Documentation mentions the following.

The nodes of an Internet-facing load balancer have public IP addresses.

The DNS name of an Internet-facing load balancer is publicly resolvable to the public IP addresses of the nodes.

Therefore, Internet-facing load balancers can route requests from clients over the Internet.

The nodes of an internal load balancer have only private IP addresses.

The DNS name of an internal load balancer is publicly resolvable to the private IP addresses of the nodes.

Therefore, internal load balancers can only route requests from clients with access to the VPC for the load balancer.

AWS Load Balancers are a critical component of a high-availability architecture in the AWS cloud. They help distribute traffic across multiple instances, improving application availability and scalability.

Here are the details regarding each statement and whether it is true or false:

A. The nodes of an Internet-facing load balancer do not have public IP addresses

• This statement is True. In an Internet-facing load balancer, the nodes are instances in a public subnet that do not have public IP addresses. The load balancer itself has a public IP address that is associated with its DNS name.

B. The DNS name of an Internet-facing load balancer is publicly resolvable to the public IP address(es) of the load balancer(s)

• This statement is True. The DNS name of an Internet-facing load balancer is publicly resolvable to the public IP address(es) of the load balancer(s). When a client sends a request to the DNS name of an Internet-facing load balancer, the request is resolved to the public IP address of the load balancer, and then the load balancer distributes the traffic to its registered instances.

C. The nodes of an internal load balancer have only private IP addresses

• This statement is True. In an internal load balancer, the nodes are instances in a private subnet that have only private IP addresses. The load balancer DNS name is resolvable only within the VPC and is not publicly resolvable.

D. The nodes of an internal load balancer does not have public IP addresses.

• This statement is True. In an internal load balancer, the nodes do not have public IP addresses because they are located in a private subnet.

Therefore, the false statement regarding AWS Load Balancers is not among the options provided. All statements are true.
