Question 46

An organization's security policy requires multiple copies of all critical data to be replicated across at least a primary and backup data center. The organization has decided to store some critical data on Amazon S3. Which option should you implement to ensure this requirement is met?

  1. Use the S3 copy API to replicate data between two S3 buckets in different regions
  2. You do not need to implement anything since S3 data is automatically replicated between regions
  3. Use the S3 copy API to replicate data between two S3 buckets in different facilities within an AWS Region
  4. You do not need to implement anything since S3 data is automatically replicated between multiple facilities within an AWS Region

Question 47

You are tasked with setting up a cluster of EC2 Instances for a NoSQL database. The database requires random read I/O disk performance up to a 100,000 IOPS at 4KB block side per node. Which of the following EC2 instances will perform the best for this workload?

  1. A High-Memory Quadruple Extra Large (m2.4xlarge) with EBS-Optimized set to true and a PIOPs EBS volume
  2. A Cluster Compute Eight Extra Large (cc2.8xlarge) using instance storage
  3. High I/O Quadruple Extra Large (hi1.4xlarge) using instance storage
  4. A Cluster GPU Quadruple Extra Large (cg1.4xlarge) using four separate 4000 PIOPS EBS volumes in a RAID 0 configuration

Question 48

When an EC2 EBS-backed (EBS root) instance is stopped, what happens to the data on any ephemeral store volumes?

  1. Data will be deleted and win no longer be accessible
  2. Data is automatically saved in an EBS volume.
  3. Data is automatically saved as an EBS snapshot
  4. Data is unavailable until the instance is restarted

Question 49

Your team Is excited about the use of AWS because now they have access to programmable Infrastructure" You have been asked to manage your AWS infrastructure in a manner similar to the way you might manage application code You want to be able to deploy exact copies of different versions of your infrastructure, stage changes into different environments, revert back to previous versions, and identify what versions are running at any particular time (development test QA. production). Which approach addresses this requirement?

  1. Use cost allocation reports and AWS Opsworks to deploy and manage your infrastructure.
  2. Use AWS CloudWatch metrics and alerts along with resource tagging to deploy and manage your infrastructure.
  3. Use AWS Beanstalk and a version control system like GIT to deploy and manage your infrastructure.
  4. Use AWS CloudFormation and a version control system like GIT to deploy and manage your infrastructure.

Question 50

You have a server with a 5O0GB Amazon EBS data volume. The volume is 80% full. You need to back up the volume at regular intervals and be able to re-create the volume in a new Availability Zone in the shortest time possible. All applications using the volume can be paused for a period of a few minutes with no discernible user impact. Which of the following backup methods will best fulfill your requirements?

  1. Take periodic snapshots of the EBS volume
  2. Use a third party Incremental backup application to back up to Amazon Glacier
  3. Periodically back up all data to a single compressed archive and archive to Amazon S3 using a parallelized multi-part upload
  4. Create another EBS volume in the second Availability Zone attach it to the Amazon EC2 instance, and use a disk manager to mirror me two disks
