A customer is looking for a storage archival solution for 1,000 TB of data. The customer requires that the solution be durable and data be available within a few hours of requesting it, but not exceeding a day. The solution should be as cost-effective as possible.
To meet security compliance policies, data must be encrypted at rest. The customer expects they will need to fetch the data two times in a year.
Which storage solution should a Solutions Architect recommend to meet these requirements?

• A.Copy data to Amazon S3 buckets by using server-side encryption. Move data to Amazon S3 to reduce redundancy storage (RRS).
• B.Copy data to encrypted Amazon EBS volumes, then store data into Amazon S3.
• C.Copy each object into a separate Amazon Glacier vault, and let Amazon Glacier take care of encryption.
• D.Copy data to Amazon S3 with server-side encryption. Configure lifecycle management policies to move data to Amazon Glacier after 0 days.

The following IAM policy is attached to an IAM group. This is the only policy applied to the group.

What are the effective IAM permissions of this policy for group members?

• A.Group members are allowed the ec2:StopInstances and ec2:Terminatelnstances permissions for all Regions when logged in with multi-factor authentication (MFA). Group members authorized any other Amazon EC2 action.
• B.Group member are denied any Amazon EC2 permissions in the us-east-1 Region unless they are tagged in with multi-factor authentication (MFA).
• C.Group members are permitted any Amazon EC2 action within the uss-east-1 Region. Statements after The Allow permission are not applied
• D.Group members are allowed the ec2:Stoplnstances and ec2:Terminatelnstances permissions for the us-east-1 Region only when logged in with multi-factor authentication (MFA). Groups are permitted any other Amazon EC2 action within the us-east-1 Region

Application developers have noticed that a production application is very slow when business reporting users run large production reports against the Amazon RDS instance backing the application. the CPU and memory utilization metrics for the RDS instance-d not exceed 60% while the reporting queries are running. The business reporting users must be able to generate reports without affecting the applications performance.
Which action will accomplish this?

• A.Create a read replication and connect the business reports to it.
• B.Increase the size of the RDS instance
• C.Create a read replica and connect the application to it.
• D.Enable multiple Availability Zones on the RDS instance

A company is building a web-based application running on Amazon EC2 instances in multiple Availability Zones. The web application will provide access to a repository of text documents totaling about 900 TB in size.
The company anticipates that the web application will experience periods of high demand. A solutions architect must ensure that the storage component for the text documents can scale to meet the demand of the application at all times. The company is concerned about the overall cost of the solution.
Which storage solution meets these requirements MOST cost-effectively?

• A.Amazon Elastic Block Store (Amazon EBS)
• B.Amazon Elastic File System (Amazon EFS)
• C.Amazon Elasticsearch Service (Amazon ES)
• D.Amazon S3

Your website is serving on-demand training videos to your workforce. Videos are uploaded monthly in high resolution MP4 format. Your workforce is distributed globally often on the move and using company-provided tablets that require the HTTP Live Streaming (HLS) protocol to watch a video. Your company has no video transcoding expertise and it required you may need to pay for a consultant.
How do you implement the most cost-efficient architecture without compromising high availability and quality of video delivery'?

• A.Elastic Transcoder to transcode original high-resolution MP4 videos to HLS. EBS volumes to host videos and EBS snapshots to incrementally backup original files after a few days. CloudFront to serve HLS transcoded videos from EC2.
• B.A video transcoding pipeline running on EC2 using SQS to distribute tasks and Auto Scaling to adjust the number of nodes depending on the length of the queue. 53 to host videos with Lifecycle Management to archive all files to Glacier after a few days. CloudFront to serve HLS transcoded videos from Glacier.
• C.A video transcoding pipeline running on EC2 using SQS to distribute tasks and Auto Scaling to adjust the number of nodes depending on the length of the queue. EBS volumes to host videos and EBS snapshots to incrementally backup original files after a few days. CloudFront to serve HLS transcoded videos from EC2.
• D.Elastic Transcoder to transcode original high-resolution MP4 videos to HLS. 53 to host videos with Lifecycle Management to archive original files to Glacier after a few days. CloudFront to serve HLS transcoded videos from 53.
