Connect an ALB entry, private EC2 application, RDS database and limited IAM permissions. Prove actual order writes and reads, repair a failed release, then rebuild network resources and recover original database and EBS report data.
What you will practice
Private deployment and encrypted configuration; diagnosis with target health and safe logs; snapshot recovery and cleanup that preserves unrelated resources.
Prerequisites and environment
Complete the relevant S3, IAM, VPC, EC2/EBS, Load Balancing, RDS, Monitoring and Application Security labs first; complete CloudFormation before the recovery challenge. The three challenges start independently in provided browser-based Linux VMs. Use Terminal and AWS View; no personal AWS account or previous VM resources are needed. Code and fixtures are supplied, and complete solutions explain the operations.
Certification practice
Apply selected CLF-C02, SAA-C03 and DVA-C02 capabilities listed in each challenge. This supplements study of the current exam guide; it does not cover an entire exam or measure production RTO/RPO or multi-Region disaster recovery.
