ISC2 Systems Security Certified Practitioner (SSCP) Practice Question

Your company runs a customer-facing web service on AWS. Two EC2 instances in one Availability Zone sit behind a Network Load Balancer scoped to that zone, and a single-AZ Amazon RDS for MySQL instance stores data. After an AZ-wide outage, management wants the service to stay online during a complete AZ failure, adding as little cost as possible and requiring no code changes. What should you do?

  • Replace the Network Load Balancer with a larger single EC2 instance running HAProxy in the existing Availability Zone.

  • Take nightly AMIs and database snapshots and plan to launch replacement resources manually if the current AZ becomes unavailable.

  • Configure cross-region replication for RDS and move the application servers to a single AZ in the secondary region.

  • Enable Multi-AZ for the RDS instance and update the Auto Scaling group and Network Load Balancer to distribute EC2 instances across two Availability Zones.
