Domain 2.2: Business Continuity

An enterprise needs to back up Amazon EC2 instances, Amazon RDS databases, and Amazon EFS file systems across multiple AWS Regions. The backups must be immutable to protect against ransomware. Which solution is MOST operationally efficient?

An application uses Amazon S3 to store millions of images. The business requires that if an image is accidentally deleted, it can be recovered within 30 days. However, to save costs, older versions of images should be transitioned to cheaper storage. Which S3 feature combination meets this requirement?

An enterprise is designing a backup strategy for a complex application spanning Amazon EC2, Amazon EBS, Amazon RDS, and Amazon DynamoDB. They need centralized management, immutable backups to protect against ransomware, and cross-region replication for DR. Which THREE actions should the architect take? (Select THREE)

An enterprise is designing a multi-region architecture for a critical web application. They need to route traffic to the region with the lowest latency for the user, but if a region fails, traffic must automatically failover to the healthy region. Which THREE Route 53 configurations are required? (Select THREE)

An application requires a highly available, POSIX-compliant file system that can be mounted concurrently by hundreds of EC2 instances across multiple Availability Zones. Which AWS service meets this requirement?

A financial institution requires that all EBS volumes, S3 buckets, and RDS databases are backed up daily. Backups must be retained for 7 years and protected against accidental deletion, even by administrators. What is the BEST solution?

A critical database runs on Amazon EC2 with EBS volumes. The business requires application-consistent backups every 4 hours. How can this be achieved with the LEAST operational overhead?

An architecture uses Amazon S3 to store critical documents. To meet compliance, the company must prove that documents have not been altered since creation, and they must be retained for exactly 5 years. Which S3 feature meets this requirement?

An application requires highly available file storage accessible by hundreds of EC2 Linux instances across multiple Availability Zones. The storage must support POSIX permissions and scale automatically. Which TWO actions should the architect take? (Select TWO)

A company is designing a new document management system on AWS. Documents uploaded to Amazon S3 must be retained for 7 years for compliance. During the first 30 days, documents are accessed frequently. After 30 days, they are rarely accessed but must be retrievable within minutes. After 1 year, they are almost never accessed and a retrieval time of 12 hours is acceptable. Documents must not be deleted before 7 years. Which combination of actions meets these requirements MOST cost-effectively? (Select THREE)

An enterprise is designing a backup strategy for its AWS environment. They have hundreds of EC2 instances, RDS databases, and EFS file systems across 20 accounts in AWS Organizations. Compliance requires that all backups be stored in a centralized, isolated account and retained for 5 years. Backups must be immutable. What is the MOST operationally efficient solution?

A company is designing a disaster recovery plan for an Amazon RDS for MySQL database. The database is 5 TB in size. The business requires an RPO of 5 minutes and an RTO of 2 hours. They want to minimize costs and do not want to run a continuous replica in the DR region. Which strategy meets these requirements?

An enterprise is designing a disaster recovery strategy for a critical application. The application uses Amazon EC2, Amazon RDS, and Amazon S3. The business requires a Recovery Time Objective (RTO) of 4 hours and a Recovery Point Objective (RPO) of 1 hour. They want to minimize costs while meeting these requirements. Which DR strategy is the MOST cost-effective?

A company is designing a highly resilient architecture for a critical application. They want to ensure that if an entire AWS Region goes down, they can recover the application in a secondary region. The application uses Amazon EC2 instances, an Application Load Balancer, and Amazon RDS for MySQL. They have chosen a 'Warm Standby' strategy. Which actions are required to implement this strategy? (Select THREE)

An enterprise requires centralized backup management across 50 AWS accounts. Backups for EC2, RDS, and EFS must be taken daily, retained for 30 days, and copied to a central archive account in a different region. How should this be implemented?

A critical database runs on Amazon EC2 with EBS volumes. The business requires an RPO of 5 minutes. The database does not support native clustering. How can the architect meet this RPO requirement?

A company hosts a static website on Amazon S3 fronted by CloudFront. They want to ensure the website remains available even if the primary S3 bucket is accidentally deleted or becomes unavailable. What is the MOST cost-effective solution?

An architecture uses Amazon RDS for MySQL. The business requires that the database can survive an Availability Zone failure with zero data loss (RPO=0) and automatic failover. Which configuration is required?

A company has a strict compliance requirement that all EBS snapshots must be tested monthly to ensure they can be successfully restored into functional EC2 instances. How can this be automated with the LEAST operational overhead?

A company is designing a disaster recovery plan for a critical application. The application uses Amazon EC2, Amazon RDS for MySQL, and Amazon S3. The business requires an RPO of 1 hour and an RTO of 4 hours. The DR site is in a different AWS Region. Which combination of actions will meet these requirements MOST cost-effectively? (Select THREE)

A company has a multi-account environment managed by AWS Organizations. They want to ensure that all Amazon EBS snapshots are automatically copied to a central disaster recovery account in a different region. What is the MOST operationally efficient way to implement this?
