Which solution will meet these requirements?

  1. Amazon Simple Queue Service (Amazon SQS) queue
  2. Application Load Balancer
  3. AWS Global Accelerator
  4. Network Load Balancer

A SysOps administrator is using AWS CloudFormation StackSets to create AWS resources in two AWS Regions in the same AWS account. A stack operation fails in one Region and returns the stack instance status of OUTDATED.
What is the cause of this failure?

  1. The CloudFormation template changed on the local disk and has not been submitted to CloudFormation.
  2. The CloudFormation template is trying to create a global resource that is not unique.
  3. The stack has not yet been deployed to the Region.
  4. The SysOps administrator is using an old version of the CloudFormation API.

A SysOps administrator must configure Amazon S3 to host a simple nonproduction webpage. The SysOps administrator has created an empty S3 bucket from the
AWS Management Console. The S3 bucket has the default configuration in place.
Which combination of actions should the SysOps administrator take to complete this process? (Choose two.)

  1. Configure the S3 bucket by using the "Redirect requests for an object" functionality to point to the bucket root URL.
  2. Turn off the "Block all public access" setting. Allow public access by using a bucket ACL that contains <Permission>WEBSITE</Permission>.
  3. Turn off the "Block all public access" setting. Allow public access by using a bucket ACL that allows access to the AuthenticatedUsers grantee.
  4. Turn off the "Block all public access" setting. Set a bucket policy that allows "Principal": the s3:GetObject action.
  5. Create an index.html document. Configure static website hosting, and upload the index document to the S3 bucket.

A company is using an Amazon Aurora MySQL DB cluster that has point-in-time recovery, backtracking, and automatic backup enabled. A SysOps administrator needs to be able to roll back the DB cluster to a specific recovery point within the previous 72 hours. Restores must be completed in the same production DB cluster.
Which solution will meet these requirements?

  1. Create an Aurora Replica. Promote the replica to replace the primary DB instance.
  2. Create an AWS Lambda function to restore an automatic backup to the existing DB cluster.
  3. Use backtracking to rewind the existing DB cluster to the desired recovery point.
  4. Use point-in-time recovery to restore the existing DB cluster to the desired recovery point.

  2. Reattach the EBS volume to the EC2 instance.
  3. Reboot the EC2 instance that is attached to the EBS volume.
