A SysOps Administrator manages an application that stores object metadata in Amazon S3.
There is a requirement to have S2 server-side encryption enabled on all new objects in the bucket.
How can the Administrator ensure that all new objects to the bucket satisfy this requirement?

• A.Apply the authorization header to S3 requests for S3 server-side encryption.
• B.Create an S3 lifecycle rule to automatically encrypt all new objects.
• C.Use put-object-acl to allow objects to be encrypted with S2 server-side encryption.
• D.Enable default bucket encryption to ensure that all new objects are encrypted.

A SysOps Administrator has configured a CloudWatch agent to send custom metrics to Amazon CloudWatch and is now assembling a CloudWatch dashboard to display these metrics.
What steps should be the Administrator take to complete this task?

• A.Select the AWS Namespace, filter by metric name, then add to the dashboard.
• B.Open the CloudWatch console, from the CloudWatch Events, add all custom metrics.
• C.Select the appropriate widget and metrics from the custom namespace, then add to the dashboard.
• D.Add a text widget, select the appropriate metric from the custom namespace, then add to the dashboard.

A company is using AWS Storage Gateway to create block storage volumes and mount them as Internet Small Computer Systems Interface (iSCSI) devices from on-premises servers. As the Storage Gateway has taken on several new projects, some of the Development teams report that the performance of the iSCSI drives has degraded. When checking the Amazon CloudWatch metrics, a SysOps Administrator notices that the CacheHitPercent metric is below 60% and the CachePercentUsed metric is above 90%.
What steps should the Administrator take to increase Storage Gateway performance?

• A.Take point-in-time snapshots of all the volumes in Storage Gateway, flush the cache completely, then restore the volumes from the clean snapshots.
• B.Ensure that the physical disks for the Storage Gateway are in a RAID 1 configuration to allow higher throughput.
• C.Create a larger disk for the cached volume. In the AWS Management Console, edit the local disks, then select the new disk as the cached volume.
• D.Change the default block size for the Storage Gateway from 64 KB to 128 KB, 256 KB, or 512 KB to improve I/O performance.

A user has launched an EC2 instance from an instance store backed AMI.
The user has attached an additional instance store volume to the instance.
The user wants to create an AMI from the running instance.
Will the AMI have the additional instance store volume data?

• A.No, since the instance store backed AMI can have only the root volume bundled
• B.It is not possible to attach an additional instance store volume to the existing instance store backed AMI instance
• C.Yes, the block device mapping will have information about the additional instance store volume
• D.No, since this is ephermal storage it will not be a part of the AMI
