AWS Storage

A company needs to maintain access logs for a minimum of 5 years due to regulatory requirements. The data is rarely accessed once stored, but it must be accessible with one day’s notice if it is needed. What is the MOST cost-effective data storage solution that meets these requirements?

• A. Store the data in Amazon S3 Glacier Deep Archive storage and delete the objects after 5 years using a lifecycle rule

• B. Store the data in Amazon S3 standard storage and transition to Amazon S3 Glacier after 30 days using a lifecycle rule

• C. Store the data in logs using Amazon CloudWatch Logs and set the retention period to 5 years

• D. Store the data in Amazon S3 Standard-Infrequent Access (S3 Standard-IA) storage and delete the objects after 5 years using a lifecycle rule

When storing data in Amazon S3, you can define to automatically archive sets of Amazon S3 objects to less expensive Amazon S3 storage classes.

• A. Object versioning.

• B. Lifecycle Rules

• C. Object encryption

• D. AWS Glacier.

Q. A user has hosted objects on AWS in the bucket techmaster. Can a Javascript of the website www.techmaster.vn directly access the objects of the bucket?

• A. Yes with S3 CORS support

• B. Yes with S3 1AM Support

• C. No, its a security violation

• D. No, one domain cannot interact with the objects of another domain

Q. An IT department manages a content management system (CMS) running on an Amazon EC2 instance mounted to an Elastic File System (EFS). The CMS throughput demands are high compared to the amount of data stored on the file system.

What is the appropriate EFS configuration in this case?

• A. Choose Provisioned Throughput mode for the file system

• B. Choose Bursting Throughput mode for the file system

• C. Start with the General Purpose performance mode and update the file system to Max I/O if it reaches its I/O limit

• D. Start with Bursting Throughput mode and update the file system to Max I/O if it reaches its I/O limit

Q. A photo-sharing application uses a fleet of EC2 instances to assemble photos into a package that professional photographers can share with clients. To improve performance, the team uses multiple Amazon EC2 instances in parallel to resize and prepare each image with a watermark. During the build process, the EC2 instances require shared access to common storage to retrieve and save each photograph in the package. After the package is complete, it should be stored in the cloud so that only authorized clients can review the contents.

Which of the following storage solutions will allow shared access between EC2 instances and enable clients access to the final package described in this scenario?

• A. (1) Use Elastic Block storage (Amazon EBS) for persistent storage shared across EC2 instances. (2) Save packages to a private Amazon S3 bucket, create an IAM user for the client, and grant this user read access to the S3 bucket

• B. (1) Use Elastic File storage (Amazon EFS) for persistent storage shared across EC2 instances. (2) Save client packages to a private Amazon S3 bucket and provide client access using a CloudFront signed URL.

• C. (1) Use Elastic Block storage (Amazon EBS) for persistent storage shared across EC2 instances. (2) Save client packages to a private Amazon S3 bucket and provide client access using a CloudFront signed URL.

• D. (1) Use Elastic File storage (Amazon EFS) for persistent storage shared across EC2 instances. (2) Save packages to a private Amazon S3 bucket, create an IAM user for the client, and grant this user read access to the S3 bucket.

Q. A research institution has a growing number of source code repositories hosted on multiple servers and managed by different IT departments. The institution plans to consolidate these repositories and deploy a GitHub Enterprise Server on a single Amazon EC2 instance. The team needs to select the appropriate Amazon storage service for the data volume of the instance running the GitHub Enterprise Server.

Which of the following storage solutions should the team choose for this deployment?

• A. Elastic File Service (EFS)

• B. Simple Storage Service (S3)

• C. EC2 Instance storage

• D. Elastic Block store (EBS)

Q. Amazon Elastic Block store (Amazon EBS) provides block level storage volumes for use with EC2 instances. EBS volumes are highly available and reliable storage volumes that can be attached to any running instance that is in the same Availability Zone. Which of the following would be considered a feature of EBS? (Choose 3 answers)

• A. EBS volumes behave like raw, unformatted block devices. You can create a file system on top of these volumes, or use them in any other way you would use a block device (like a hard drive).

• B. EBS volumes are created in a specific region, and can then be attached to any instances in that same region.

• C. You can use encrypted EBS volumes to meet a wide range of data-at-rest encryption requirements for regulated/audited data and applications.

• D. Your account does not have a limit on the number of EBS volumes that you can use, and the total storage available to you is also unlimited.

• E. You can create point-in-time snapshots of EBS volumes, which are persisted to Amazon S3. Snapshots protect data for long-term durability, and they can be used as the starting point for new EBS volumes.
