Question # 13

A SysOps administrator is implementing automated I/O load performance testing as part of lite continuous integraliorVcontinuous delivery (CI'CD) process for an application The application uses an Amazon Elastic Block Store (Amazon E8S) Provisioned IOPS volume for each instance that is restored from a snapshot and requires consistent I/O performance. During the initial tests, the I/O performance results are sporadic. The SysOps administrator must ensure that the tests yield more consistent results. Which actions could the SysOps administrator take to accomplish this goal? (Select TWO.)

A. Restore the EBS volume from the snapshot with fast snapshot restore enabled
B. Restore the EBS volume from the snapshot using the cold HDD volume type.
C. Restore the EBS volume from the snapshot and pre-warm the volume by reading all ofthe blocks.
D. Restore the EBS volume from the snapshot and configure encryption.
E. Restore the EBS volume from the snapshot and configure I/O block sizes at random

Question # 15

A company will migrate its on-premises enterprise system to AWS. The enterprise system will be hosted on memory optimized Amazon EC2 instances across multiple Availability Zones. The enterprise system needs shared file storage that is scalable and block-based. A SysOps team must configure the encryption of data in transit tor the shared He system and develop a backup strategy to cost-effectively store the file system data centrally. Which solution will meet these requirements?

A. Use Amazon Elastic Block Store (Amazon EBS) for the shared file storage. Mount the EBS volume to the EC2 instances. Use a custom script to create a backup of the entire file system and protect data in transit by using SSL 
B. Use Amazon Elastic File System (Amazon EFS) for the shared file storage. Use AWS Backup to configure backups. Use lifecycle policies to automatically transition backups to cold storage. Use the amazon-efs-utils package to mount the EFS file system by using the TLS options
C. Use Amazon Elastic File System (Amazon EFS) for the shared file storage. Use AWS Backup to configure backups. Use lifecycle policies to automatically transition backups to cold storage Perform data-in-transit encryption by using client-side encryption. 
D. Use Amazon S3 for the shared file storage. Mount the S3 bucket directory to the EC2 instances. Use an S3 Lifecycle policy to archive the data in Amazon S3 Glacier.

Scaling out Is triggered when the CPU Utilization instance metric is more than 75% across the Auto Scaling group. The administrator noticed aggressive scaling out. Developers suspect an application memory leak that is causing aggressive garbage collection cycles. How can the administrator troubleshoot the application without triggering the scaling process?

A. Create a scale down trigger when the CPUUtilization instance metric is at 70%.
B. Delete the Auto Scaling group and recreate it when troubleshooting is complete
C. Remove impacted instances from the Application Load Balancer.
D. Suspend the scaling process before troubleshooting.

Question # 20

A company is using AWS Storage Gateway to create block storage volumes and mount them as Internet Small Computer Systems Interlace (iSCSI) devices from on-premise! 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 cachePercentUsed metric is below 60% and the cachePercentUsed metric is above 90%. What steps should the Administrator take to increase Storage Gateway performance?

A. Change the default block size for the Storage Gateway from 64 KB to 128 KB 256 KB or512 KB to improve I/O performance
B. Create a larger disk for the cached volume. In the AWS Management Console. edit thelocal disks then select the new disk as the cached volume
C. Ensure that the physical disks for the Storage Gateway are in a RAID 1 configuration toallow higher throughput
D. Take point in time snapshots of all the volumes in Storage Gateway flush the cachecompletely then restore the volumes from the clean snapshots
