• Question 845:

  A user is running a batch process on EBS backed EC2 instances. The batch process launches few EC2 instances to process Hadoop Map reduce jobs which can run between 50 ?600 minutes or sometimes for even more time. The user wants a configuration that can terminate the instance only when the process is completed.

  How can the user configure this with CloudWatch?

  A. Configure a job which terminates all instances after 600 minutes

  B. It is not possible to terminate instances automatically

  C. Configure the CloudWatch action to terminate the instance when the CPU utilization falls below 5%

  D. Set up the CloudWatch with Auto Scaling to terminate all the instances

  Correct Answer: C

  Amazon CloudWatch alarm watches a single metric over a time period that the user specifies and performs one or more actions based on the value of the metric relative to a given threshold over a number of time periods. The user can setup an action which terminates the instances when their CPU utilization is below a certain threshold for a certain period of time. The EC2 action can either terminate or stop the instance as part of the EC2 action. Reference: http://docs.aws.amazon.com/AmazonCloudWatch/latest/DeveloperGuide/UsingAlarmActions.html

• Question 846:

  A 3-Ber e-commerce web application is currently deployed on-premises, and will be migrated to AWS for greater scalability and elasticity. The web tier currently shares read-only data using a network distributed file system. The app server tier uses a clustering mechanism for discovery and shared session state that depends on IP multicast. The database tier uses shared-storage clustering to provide database failover capability, and uses several read slaves for scaling. Data on all servers and the distributed file system directory is backed up weekly to off-site tapes.

  Which AWS storage and database architecture meets the requirements of the application?

  A. Web servers: store read-only data in S3, and copy from S3 to root volume at boot time. App servers: share state using a combination of DynamoDB and IP unicast. Database: use RDS with multi-AZ deployment and one or more read replicas. Backup: web servers, app servers, and database backed up weekly to Glacier using snapshots.

  B. Web servers: store read-only data in an EC2 NFS server, mount to each web server at boot time. App servers: share state using a combination of DynamoDB and IP multicast. Database: use RDS with multi- AZ deployment and one or more Read Replicas. Backup: web and app servers backed up weekly via AMIs, database backed up via DB snapshots.

  C. Web servers: store read-only data in S3, and copy from S3 to root volume at boot time. App servers: share state using a combination of DynamoDB and IP unicast. Database: use RDS with multi-AZ deployment and one or more Read Replicas. Backup: web and app servers backed up weekly via AMIs, database backed up via DB snapshots.

  D. Web servers: store read-only data in S3, and copy from S3 to root volume at boot time App servers: share state using a combination of DynamoDB and IP unicast. Database: use RDS with multi-AZ deployment. Backup: web and app servers backed up weekly via AMIs, database backed up via DB snapshots.

  Correct Answer: A

  Amazon Glacier doesn't suit all storage situations. Listed following are a few storage needs for which you should consider other AWS storage options instead of Amazon Glacier. Data that must be updated very frequently might be better served by a storage solution with lower read/write latencies, such as Amazon EBS, Amazon RDS, Amazon DynamoDB, or relational databases running on EC2.

  Correct Answer: C

• Question 848:

  Amazon EC2 provides a repository of public data sets that can be seamlessly integrated into AWS cloud-based applications.

  What is the monthly charge for using the public data sets?

  A. A 1-time charge of 10$ for all the datasets.

  B. 1$ per dataset per month

  C. 10$ per month for all the datasets

  D. There is no charge for using the public data sets

  Correct Answer: D

• Question 849:

  Within the IAM service a GROUP is regarded as a:

  A. A collection of AWS accounts

  B. It's the group of EC2 machines that gain the permissions specified in the GROUP.

  C. There's no GROUP in IAM, but only USERS and RESOURCES.

  D. A collection of users.

  Correct Answer: D

  Use groups to assign permissions to IAM users Instead of defining permissions for individual IAM users, it's usually more convenient to create groups that relate to job functions (administrators, developers, accounting, etc.), define the relevant permissions for each group, and then assign IAM users to those groups. All the users in an IAM group inherit the permissions assigned to the group. That way, you can make changes for everyone in a group in just one place. As people move around in your company, you can simply change what IAM group their IAM user belongs to.

• Question 850:

  When you put objects in Amazon S3, what is the indication that an object was successfully stored?

  A. A HTTP 200 result code and MD5 checksum, taken together, indicate that the operation was successful.

  B. Amazon S3 is engineered for 99.999999999% durability. Therefore there is no need to confirm that data was inserted.

  C. A success code is inserted into the S3 object metadata.

  D. Each S3 account has a special bucket named _s3_logs. Success codes are written to this bucket with a timestamp and checksum.

  Correct Answer: A
