You are running a website that keeps historical photos from previous elections. Users Need to be able to search for and display images from the last 100 years. On average, most Images are requested only once or twice a year. What would be the most cost-effective, highly available method of storing and serving the images?

  • Save images on Amazon Elastic Block Store (Amazon EBS) and use a Web server running on Amazon Elastic Compute Cloud (Amazon EC2).
  • Save image on Amazon Elastic File System (Amazon EFS) and use a web server running on Amazon EC2.
  • Save images on Amazon Simple Storage Service (Amazon S3) and serve direct from Amazon S3.
  • Save images on Amazon Simple Storage Service- Infrequent Access (Amazon S3-IA) and serve direct from Amazon S3.
  • Save images on Amazon Glacier and serve direct Amazon Glacier.

You are images a legacy Sybase database on an Amazon Elastic Compute Cloud (Amazon EC2) instance running Windows. You average 1,200 transaction per second against the database, but at pear levels have as many as 2,500 transactions per second. The current size of the database is 1.8 TB. What is the best data volume Amazon Elastic Block Store (Amazon EBS) configuration for cost without sacrificing performance?

  • One Amazon EBS Magnetic Volume provisioned at 2 TB with 2,500 provisioned IOPS
  • Two Amazon EBS Magnetic Volumes, each provisioned at 1 TB and Raid0 connected
  • One Amazon ESB gp2 volume provisioned at 2 TB
  • One Amazon ESB Solid State Drive (SSD) provisioned at 2 TB with 2,500 provisioned
  • Two Amazon ESB gp2 volumes, each provisioned at 1 TB and RaidO connected

Your application’s Amazon Elastic Compute Cloud (Amazon EC2) instances need a single shared volume to edit common files. What is the best volume to attach to the instances?

  • One Amazon Elastic Block Store (Amazon EBS) volume with IOPS
  • One Amazon EBS ma1 volume
  • One Amazon EBS Elastic Files System Service (Amazon EFS) volume
  • One Amazon Simple Storage Service (Amazon S3) volume
  • One Amazon ESB gp2 volume

Your Company is planning to keep a media archive of photo that are rarely accessed (no more than 10 times a years on average). Business needs expect that media be available for publishing on request with a response time of less than 800 ms. What is the most cost-efficient storage method for the media?

  • Amazon Elastic Block Store (Amazon EBS) with provisioned IOPS
  • Amazon EBS gp2
  • Amazon Simple Storage Service – Reduced Redundancy Storage (Amazon S3-RRS)
  • Amazon S3 – Infrequent Access (Amazon S3- IA)
  • Amazon Glacier

Which of the following would be good use cases for Amazon Simple Storage Service (Amazon S3)? (Choose three.)

  • Compiled Application installers
  • Video Clip storage From motion-activated cameras
  • .dat files from active databases
  • Scratch dish for video transcoders
  • Data warehouse repositoriese
  • Amazon Elastic Compute cloud (Amazon EC2) session state offloading

Your Company has a Compliance requirement to all writes to an Amazon Simple Storage Service (Amazon S3) bucket and any time that content was read publicly. What are the two Steps needed to achieve compliance? (Choose two.)

  • Activate AWS Identity and Access Management (IAM) logging.
  • Activate AWS CloudTrail logging.
  • Activate Amazon CloudWatch logging.
  • Activate Server Access logging.
  • Activate ClearCut logging.

You Company must retain legacy compliance data for five years in “an immutable from “ in the unlikely event of tax audit. What is the most cost-effective method that will achieve compliance?

  • Amazon Glacier with Vault Lock activated
  • Amazon Glacier with AWS Identity and Access Management (IAM) permission to edit and delete objects denied
  • Amazon Simple Storage Service (Amazon S3) With cross-region replication activated
  • Amazon S3 Infrequent Access (Amazon S3-IA) with Bucked Lock activated
  • AWS Storage Gateway with tape interface

You want to use AWS Storage Gateway to increase the amount of storage available to your on-premises application block storage systems. What is the correct configuration?

  • AWS Storage Gateway file interface
  • AWS Storage Gateway volume interface with cached mode
  • AWS Storage Gateway volume interface with stored mode
  • AWS Storage Gateway tape interface

What is a good use case for Amazon Elastic Computer Cloud (Amazon EC2) instances storage?

  • Compiled application installers
  • Video clips storage from motion-activated cameras
  • .dat files from, active databases
  • Scratch dish for video transcoders
  • Data warehouse repositories
  • Amazon EC2 session state offloading

What step must you do as part of provisioning and mounting Amazon Elastic File System (Amazon EFB) on You Amazon Elastic Compute Cloud (Amazon EC2) instance?

  • Select the authorized AWS Key Management Service (AWSKMS) master key.
  • Create mount targets in the appropriate Amazon Virtual Private Cloud (Amazon VPC) subnets.
  • Activate versioning on the associated Amazon Simple Storage Service (Amazon S3) buckets.
  • Create the Amazon EFS role in AWS Identity and Access Management (IAM).
  • Connect to the iSCSI Amazon EFS endpoint.

In what ways does Amazon Simple Storage Service (Amazon S3) object storage differ from block and file storage? (Choose two.)

  • Amazon S3 storage data in fixed blocks.
  • Object can be any size.
  • Object are stored in bucked.
  • Object contain both data and metadata.

Which of following are features of Amazon Elastic Block Storage (Amazon EBS)? (Choose two.)

  • Data stored on Amazon EBS is automatically replicated within an Availability Zone.
  • Amazon ESB data automatically backed up to tape.
  • Amazon ESB volumes can be encrypted transparently to workloads on the attached instance.
  • Data on an Amazon EBS Volume is lost when the attached instance is stopped.

You need to take a snapshot of an Amazon Elastic Block Store (Amazon EBS) volume. How long will the volume be unavailable?

  • It depends on the provisioned size of the volume.
  • The volume will be available immediately.
  • It depends on the amount of data stored on the volume.
  • It depends on whether the attached instance is an Amazon EBS-optimized instance.

You are restoring an Amazon Elastic Block Store (Amazon EBS) volume from a snapshot. How long will it be before the data is available?

  • It depends on the provisioned size of the volume.
  • The data will be available immediately.
  • It depends on the amount of data stored on the volume.
  • It depends on whether the attached instance is an Amazon EBS-optimized instances.

You stored critical data in Amazon Simple Storage Service (Amazon S3); the data must be protected against inadvertent or intention deletion. How can this data be protected? (Choose two.)

  • Use cross-region replication to copy data to another bucker automatically.
  • Set a vault lock.
  • Enable versioning on the bucket.
  • Use a lifecycle policy to migrate data to Amazon Glacier.
  • Enable MFA Delete on the bucket.

Amazon Glacier is well-suited to data that is which of the Following? (Choose two.)

  • False

How do you resize an instance store-backed volume?

  • Stop the Amazon Elastic Cloud Compute (Amazon EC2) instance and use the resize volume command.
  • Take a snapshot of the instance volume, resize the instance store volume, and use the snapshot to restore data to the new resized instance-store volume.
  • You cannot resize an instance store volume.
  • Attach another instance volume, Copy the data to the new volume, and delete the old volume.
