AWS Certified Advanced Networking – Specialty (ANS-C01) — Question 170

A company has an application that hosts personally identifiable information (PII) of users. All connections to the application must be secured by HTTPS with TLS certificates that implement Elliptic Curve Cryptography (ECC).

The application uses stateful connections between the web tier and the end users. Multiple instances host the application. A network engineer must implement a solution that offloads TLS connections to a load balancer.

Which load-balancing solution will meet these requirements?

Answer options

• A. Provision a Network Load Balancer. Configure a TLS listener by specifying the use of an ECC SSL certificate that is uploaded to AWS identity and Access Management (IAM). Turn on health checks to monitor the web hosts that connect to the end users.
• B. Provision an Application Load Balancer. Configure an HTTPS listener by specifying the use of an ECC SSL certificate that is uploaded to AWS Certificate Manager (ACM). Configure a default action to redirect to the URL for the application. Turn on health checks to monitor the web hosts that connect to the end users.
• C. Provision a Network Load Balancer. Configure a TLS listener by specifying the use of an ECC SSL certificate that is uploaded to AWS Certificate Manager (ACM). Turn on application-based session affinity (sticky sessions). Turn on health checks to monitor the web hosts that connect to the end users.
• D. Provision an Application Load Balancer. Configure an HTTPS listener by specifying the use of an ECC SSL certificate that is uploaded to AWS Identity and Access Management (IAM). Configure a default action to redirect to the URL for the application. Turn on application-based session affinity (sticky sessions).

Correct answer: D

Explanation

The correct choice is D because it specifies an Application Load Balancer, which is designed to handle HTTP/HTTPS traffic efficiently and can utilize an ECC SSL certificate from IAM, while also allowing for sticky sessions. The other options either use a Network Load Balancer, which is not optimal for HTTPS traffic with session affinity, or they incorrectly reference AWS services for certificate management.
