A company has an application that runs only on Amazon EC2 Spot Instances. The instances run in an Amazon EC2 Auto Scaling group with scheduled scaling actions.
However, the capacity does not always increase at the scheduled times, and instances terminate many times a day. A Sysops administrator must ensure that the instances launch on time and have fewer interruptions.
Which action will meet these requirements?

1. A. Specify the capacity-optimized allocation strategy for Spot Instance
2. B. Add more instance types to the Auto Scaling group.
3. C. Specify the capacity-optimized allocation strategy for Spot Instance
4. D. Increase the size of the instances in the Auto Scaling group.
5. E. Specify the lowest-price allocation strategy for Spot Instance
6. F. Add more instance types to the Auto Scaling group.
7. G. Specify the lowest-price allocation strategy for Spot Instance
8. H. Increase the size of the instances in the Auto Scaling group.

Correct Answer: A
Specifying the capacity-optimized allocation strategy for Spot Instances and adding more instance types to the Auto Scaling group is the best action to meet the requirements. Increasing the size of the instances in the Auto Scaling group will not necessarily help with the launch time or reduce interruptions, as the Spot Instances could still be interrupted even with larger instance sizes.

A SysOps administrator must build a solution to handle a disaster recovery (DR) scenario with the lowest recovery time objective (RTO) and recovery point objective (RPO).
Which solution meets these requirements?

1. A. Create automated snapshots of the database on a schedul
2. B. Copy the snapshots to the DR Region.
3. C. Create a cross-Region read replica for the database.
4. D. Create a Multi-AZ read replica for the database.
5. E. Schedule AWS Lambda functions to create snapshots of the source database and to copy the snapshots to a DR Region.

A company has an Amazon CloudFront distribution that uses an Amazon S3 bucket as its origin. During a review of the access logs, the company determines that some requests are going directly to the S3 bucket by using the website hosting endpoint. A SysOps administrator must secure the S3 bucket to allow requests only from CloudFront.
What should the SysOps administrator do to meet this requirement?

1. A. Create an origin access identity (OAI) in CloudFron
2. B. Associate the OAI with the distributio
3. C. Remove access to and from other principals in the S3 bucket polic
4. D. Update the S3 bucket policy to allow accessonly from the OAI.
5. E. Create an origin access identity (OAI) in CloudFron
6. F. Associate the OAI with the distributio
7. G. Update the S3 bucket policy to allow access only from the OA
8. H. Create a new origin, and specify the S3 bucket as the new origi
9. I. Update the distribution behavior to use the new origi
10. J. Remove the existing origin.
11. K. Create an origin access identity (OAI) in CloudFron
12. L. Associate the OAI with the distributio
13. M. Update the S3 bucket policy to allow access only from the OA
14. N. Disable website hostin
15. O. Create a new origin, and specify the S3 bucket as the new origi
16. P. Update the distribution behavior to use the new origi
17. Q. Remove the existing origin.
18. R. Update the S3 bucket policy to allow access only from the CloudFront distributio
19. S. Remove access to and from other principals in the S3 bucket polic
20. T. Disable website hostin
21. . Create a new origin, and specify the S3 bucket as the new origi
22. . Update the distribution behavior to use the new origi
23. . Remove the existing origin.

1. A. Deploy two Auto Scaling groups in two Availability Zones with a minimum capacity of two instances in each group.
2. B. Deploy an Auto Scaling group across two Availability Zones with a minimum capacity of four instances.
3. C. Deploy an Auto Scaling group across three Availability Zones with a minimum capacity of four instances.
4. D. Deploy an Auto Scaling group across three Availability Zones with a minimum capacity of six instances.

Correct Answer: C
