ISC2 Systems Security Certified Practitioner (SSCP) Practice Question

Your company is launching a customer-facing REST API on AWS. During the architecture review, you must show which design decision specifically addresses the availability element of the CIA triad. The workload uses Amazon EC2 instances behind an Application Load Balancer. Which of the following choices BEST demonstrates that the API will remain accessible and responsive during component failures?

  • Require TLS 1.2 for all client connections to encrypt traffic between clients and the API endpoints.

  • Protect the Application Load Balancer with AWS WAF configured to block SQL injection and cross-site scripting attacks.

  • Deploy EC2 instances across two Availability Zones, register them with the load balancer's target group, and enable Auto Scaling health checks to replace unhealthy instances automatically.

  • Enable AWS CloudTrail and store the logs in an S3 bucket with Object Lock to preserve evidence for forensic investigations.
