| Front | Back |
| Difference between RTO and RPO | RTO is Recovery Time Objective (downtime period); RPO is Recovery Point Objective (data loss window) |
| Difference between synchronous and asynchronous replication | Synchronous replication ensures identical data in real-time; asynchronous may have a lag |
| How often should backups be updated | Depends on RPO requirements; typically daily, hourly, or real-time |
| Key elements of a disaster recovery plan | Backup systems, recovery procedures, communication plans, and testing |
| Primary benefit of multi-region deployments | Ensures high availability and minimizes service disruptions across geographic regions |
| Purpose of backups | To ensure critical data is preserved and can be restored in case of a failure or disaster |
| Role of load balancers in high availability | Distributes traffic across multiple servers to prevent overload and ensure availability |
| Steps in testing a disaster recovery plan | Simulating a failure, validating recovery processes, evaluating gaps, and improving the plan |
| What is a cold backup | A backup that is not actively connected and must be manually activated during a recovery situation |
| What is a hot standby system | A backup system that is constantly running and ready to take over in case of failure |
| What is an active-active deployment | Multiple systems actively handle requests, providing redundancy and load balancing |
| What is cloud-based disaster recovery | A strategy leveraging cloud services to store backups and enable recovery operations |
| What is data replication | Copying data across multiple storage systems for high availability and fault tolerance |
| What is fault tolerance | The ability of a system to continue operating even if one or more components fail |
| Why redundancy is important in disaster recovery | Redundancy ensures no single point of failure disrupts an entire system |
About the Flashcards
Flashcards for the AWS Certified Solutions Architect Professional exam give you a quick-reference way to reinforce essential principles of system resilience and recovery. Each card targets one concept, helping you recall definitions, compare objectives like RTO vs. RPO, and understand why strategies such as hot standby or multi-region deployment keep services running.
Use the deck during daily study sessions to drill core terminology around backups, replication, and high-availability design. Practical scenarios highlight load balancers, redundancy, and cloud-based disaster recovery so you can connect theory with real operational choices-exactly the type of decision making the exam expects.
Topics covered in this flashcard deck:
- Disaster recovery planning
- Backups & replication
- Fault tolerance
- High availability architectures
- RTO vs. RPO
- Cloud-based recovery
