Exam AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 600 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Associate SAA-C03
Question #: 600
Topic #: 1
[All AWS Certified Solutions Architect - Associate SAA-C03 Questions]

A company is planning to migrate a TCP-based application into the company's VPC. The application is publicly accessible on a nonstandard TCP port through a hardware appliance in the company's data center. This public endpoint can process up to 3 million requests per second with low latency. The company requires the same level of performance for the new public endpoint in AWS.

What should a solutions architect recommend to meet this requirement?

  • A. Deploy a Network Load Balancer (NLB). Configure the NLB to be publicly accessible over the TCP port that the application requires.
  • B. Deploy an Application Load Balancer (ALB). Configure the ALB to be publicly accessible over the TCP port that the application requires.
  • C. Deploy an Amazon CloudFront distribution that listens on the TCP port that the application requires. Use an Application Load Balancer as the origin.
  • D. Deploy an Amazon API Gateway API that is configured with the TCP port that the application requires. Configure AWS Lambda functions with provisioned concurrency to process the requests.

Selected Answer: A
Since the company requires the same level of performance for the new public endpoint in AWS. A Network Load Balancer functions at the fourth layer of the Open Systems Interconnection (OSI) model. It can handle millions of requests per second. After the load balancer receives a connection request, it selects a target from the target group for the default rule. It attempts to open a TCP connection to the selected target on the port specified in the listener configuration.

Selected Answer: A
B: Is wrong as ALB is not going to help with TCP traffic C: CloudFront is CDN. There is no content here D: API Gateway is for HTTP web/API stuff, not custom TCP port applicationns
