A CloudOps engineer is troubleshooting an implementation of Amazon CloudWatch Synthetics. The CloudWatch Synthetics results must be sent to an Amazon S3 bucket.
The CloudOps engineer has copied the configuration of an existing canary that runs on a VPC that has an internet gateway attached. However, the CloudOps engineer cannot get the canary to successfully start on a private VPC that has no internet access.
What should the CloudOps engineer do to successfully run the canary on the private VPC?

1. A. Ensure that the DNS resolution option and the DNS hostnames option are turned on in the VP
2. B. Add the synthetics:GetCanaryRuns permission to the VP
3. C. On the S3 bucket, add the IgnorePublicAcls permission to the CloudWatch Synthetics role.
4. D. Ensure that the DNS resolution option and the DNS hostnames option are turned off in the VP
5. E. Create a gateway VPC endpoint for Amazon S3. Add the permissions to allow CloudWatch Synthetics to use the S3 endpoint.
6. F. Ensure that the DNS resolution option and the DNS hostnames option are turned off in the VP
7. G. Add a security group to the canary to allow outbound traffic on the DNS por
8. H. Add the permissions to allow CloudWatch Synthetics to write to the S3 bucket.
9. I. Ensure that the DNS resolution option and the DNS hostnames option are turned on in the VP
10. J. Create an interface VPC endpoint for CloudWatc
11. K. Create a gateway VPC endpoint for Amazon S3. Add the permissions to allow CloudWatch Synthetics to use both endpoints.

Correct Answer: D

A company??s architecture team must receive immediate email notifications whenever new Amazon EC2 instances are launched in the company??s main AWS production account.

8. H. Create an Amazon Simple Queue Service (Amazon SQS) queue and a subscription that uses the email protoco
9. I. Enter the architecture team's email address as the subscribe
10. J. Create an Amazon EventBridge rule that reacts when EC2 instances are launche
11. K. Specify the SQS queue as the rule's target.
12. L. Create an Amazon Simple Notification Service (Amazon SNS) topi
13. M. Configure AWS Systems Manager to publish EC2 events to the SNS topi
14. N. Create an AWS Lambda function to poll the SNS topi
15. O. Configure the Lambda function to send any messages to the architecture team's email address.

Correct Answer: B

A SysOps administrator creates a custom Amazon Machine Image (AMI) in the eu-west-2 Region and uses the AMI to launch Amazon EC2 instances. The SysOps administrator needs to use the same AMI to launch EC2 instances in two other Regions: us-east-1 and us-east-2.
What must the SysOps administrator do to use the custom AMI in the additional Regions?

1. A. Copy the AMI to the additional Regions
2. B. Make the AMI public in the Community AMIs section of the AWS Management Console
3. C. Share the AMI to the additional Region
4. D. Assign the required access permissions.
5. E. Copy the AMI to a new Amazon S3 bucke
6. F. Assign access permissions to the AMI for the additional Regions
