Answer: Create an Amazon EC2-backed Amazon Machine Image (AMI) lifecycle policy to create a backup based on tags. Schedule the backup to run twice daily. Configure the copy to the us-west-2 Region., Create a backup vault by using AWS Backup. Use AWS Backup to create a backup plan for the EC2 instances based on tag values. Define the destination for the copy as us-west-2. Specify the backup schedule to run twice daily.
## Explanation **Requirements Analysis:** 1. **Automated backups** - Currently manual, need automation 2. **Cross-region disaster recovery** - Recover in us-west-2 if us-west-1 has disaster 3. **RPO (Recovery Point Objective) ≤ 24 hours** - No more than 24 hours of data loss 4. **Least administrative effort** - Key requirement **Option Analysis:** **A:** ❌ **Incorrect** - Uses AMI lifecycle policy with scheduled backups but requires manual copy to us-west-2. This doesn't meet the automated cross-region recovery requirement. **B:** ✅ **Correct** - Uses AMI lifecycle policy with automated cross-region copy configuration. This provides: - Automated backups based on tags - Scheduled twice daily (meets ≤24 hour RPO) - Automated cross-region copy to us-west-2 - Minimal administrative effort once configured **C:** ❌ **Incorrect** - Requires creating Lambda function for copying, which adds administrative overhead and complexity. AWS Backup can handle cross-region copying natively. **D:** ✅ **Correct** - Uses AWS Backup with built-in cross-region copy functionality. This provides: - Automated backup plan based on tags - Scheduled twice daily (meets ≤24 hour RPO) - Native cross-region copy to us-west-2 without custom Lambda - Minimal administrative effort **E:** ❌ **Incorrect** - Requires manual copy to us-west-2, which doesn't meet the automated disaster recovery requirement. **Key AWS Services:** - **AMI Lifecycle Policy:** Automates creation, retention, and cross-region copying of AMIs - **AWS Backup:** Centralized backup service with native cross-region copy capabilities Both B and D provide automated, scheduled backups with automated cross-region copying, meeting all requirements with minimal administrative effort.

A company has migrated multiple Microsoft Windows Server workloads to Amazon EC2 instances that run in the us-west-1 Region. The company manually backs up the workloads to create an image as needed.
In the event of a natural disaster in the us-west-1 Region, the company wants to recover workloads quickly in the us-west-2 Region. The company wants no more than 24 hours of data loss on the EC2 instances. The company also wants to automate any backups of the EC2 instances.
Which solutions will meet these requirements with the LEAST administrative effort? (Choose two.)
A
Create an Amazon EC2-backed Amazon Machine Image (AMI) lifecycle policy to create a backup based on tags. Schedule the backup to run twice daily. Copy the image on demand.
B
Create an Amazon EC2-backed Amazon Machine Image (AMI) lifecycle policy to create a backup based on tags. Schedule the backup to run twice daily. Configure the copy to the us-west-2 Region.
C
Create backup vaults in us-west-1 and in us-west-2 by using AWS Backup. Create a backup plan for the EC2 instances based on tag values. Create an AWS Lambda function to run as a scheduled job to copy the backup data to us-west-2.
D
Create a backup vault by using AWS Backup. Use AWS Backup to create a backup plan for the EC2 instances based on tag values. Define the destination for the copy as us-west-2. Specify the backup schedule to run twice daily.
E
Create a backup vault by using AWS Backup. Use AWS Backup to create a backup plan for the EC2 instances based on tag values. Specify the backup schedule to run twice daily. Copy on demand to us-west-2.
