A company is rolling out a new version of its website. Management wants to deploy the new website in a limited rollout to 20% of the company's customers. The company uses Amazon Route 53 for its website's DNS solution.
Which configuration will meet these requirements?

1. A. Create a failover routing polic
2. B. Within the policy, configure 80% of the website traffic to be sent to the original resourc
3. C. Configure the remaining 20% of traffic as the failover record that points to the new resource.
4. D. Create a multivalue answer routing polic
5. E. Within the policy, create 4 records with the name and IP address of the original resourc
6. F. Configure 1 record with the name and IP address of the new resource.
7. G. Create a latency-based routing polic
8. H. Within the policy, configure a record pointing to the original resource with a weight of 80. Configure a record pointing to the new resource with a weight of 20.
9. I. Create a weighted routing polic
10. J. Within the policy, configure a weight of 80 for the record pointing to the original resourc
11. K. Configure a weight of 20 for the record pointing to the new resource.

Correct Answer: C

A SysOps administrator creates two VPCs, VPC1 and VPC2, in a company’s AWS account The SysOps administrator deploys a Linux Amazon EC2 instance in VPC1 and deploys an Amazon RDS for MySQL DB instance in VPC2. The DB instance is deployed in a private subnet. An application that runs on the EC2 instance needs to connect to the database.
What should the SysOps administrator do to give the EC2 instance the ability to connect to the database?

1. A. Enter the DB instance connection string into the VPC1 route table.
2. B. Configure VPC peering between the two VPCs.
3. C. Add the same IPv4 CIDR range for both VPCs.
4. D. Connect to the DB instance by using the DB instance’s public IP address.

Correct Answer: B
VPC peering allows two VPCs to communicate with each other securely. By configuring VPC peering between the two VPCs, the SysOps administrator will be able to give the EC2 instance in VPC1 the ability to connect to the database in VPC2. Once the VPC peering is configured, the EC2 instance will be able to communicate with the database using the private IP address of the DB instance in the private subnet.

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.

Correct Answer: A

A company’s reporting job that used to run in 15 minutes is now taking an hour to run. An application generates the reports. The application runs on Amazon EC2 instances and extracts data from an Amazon RDS for MySQL database.
A SysOps administrator checks the Amazon CloudWatch dashboard for the RDS instance and notices that the Read IOPS metrics are high, even when the reports are not running. The SysOps administrator needs to improve the performance and the availability of the RDS instance.
Which solution will meet these requirements?

1. A. Configure an Amazon ElastiCache cluster in front of the RDS instanc
2. B. Update the reporting job to query the ElastiCache cluster.
3. C. Deploy an RDS read replic
4. D. Update the reporting job to query the reader endpoint.
5. E. Create an Amazon CloudFront distributio
6. F. Set the RDS instance as the origi
7. G. Update the reporting job to query the CloudFront distribution.
8. H. Increase the size of the RDS instance.

Correct Answer: B
Using an RDS read replica will improve the performance and availability of the RDS instance by offloading read queries to the replica. This will also ensure that the reporting job completes in a timely manner and does not affect the performance of other queries that might be running on the RDS instance. Additionally, updating the reporting job to query the reader endpoint will ensure that all read queries are directed to the read replica.
