Q283. You are architecting a highly-scalable and reliable web application which will have a huge amount of content .You have decided to use Cloudfront as you know it will speed up distribution of your static and dynamic web content and know that Amazon C|oudFront integrates with Amazon CIoudWatch metrics so that you can monitor your web application. Because you live in Sydney you have chosen the the Asia Pacific (Sydney) region in the AWS console. However you have set up this up but no CIoudFront metrics seem to be appearing in the CIoudWatch console. What is the most likely reason from the possible choices below for this?
A. Metrics for CIoudWatch are available only when you choose the same region as the application you are
monitoring.
B. You need to pay for CIoudWatch for it to become active.
C. Metrics for CIoudWatch are available only when you choose the US East (N. Virginia)
D. Metrics for CIoudWatch are not available for the Asia Pacific region as yet.
Answer: C
Explanation:
CIoudFront is a global service, and metrics are available only when you choose the US East (N. Virginia) region in the AWS console. If you choose another region, no CIoudFront metrics will appear in the CIoudWatch console.

Q284. You need a persistent and durable storage to trace call actMty of an IVR (Interactive Voice Response) system. Call duration is mostly in the 2-3 minutes timeframe. Each traced call can be either active or terminated. An external application needs to know each minute the list of currently active calls, which are usually a few calls/second. Put once per month there is a periodic peak up to 1000 calls/second for a few hours. The system is open 24/7 and any downtime should be avoided.
Historical data is periodically archived to files. Cost saving is a priority for this project.
What database implementation would better fit this scenario, keeping costs as low as possible?
A. Use RDS Multi-AZ with two tables, one for -Active calls" and one for -Terminated ca Ils". In this way the "Active caIIs_ table is always small and effective to access.
B. Use DynamoDB with a "Calls" table and a Global Secondary Index on a "IsActive"' attribute that is present for active calls only In this way the Global Secondary index is sparse and more effective.
C. Use DynamoDB with a 'Calls" table and a Global secondary index on a 'State" attribute that can equal to "active" or "terminated" in this way the Global Secondary index can be used for all Items in the table.
D. Use RDS Multi-AZ with a "CALLS" table and an Indexed "STATE* field that can be equal to 'ACTIVE" or -TERMNATED" In this way the SOL query Is optimized by the use of the Index.
Answer: A
Q285. Your organization is in the business of architecting complex transactional databases. For a variety of reasons, this has been done on EBS. What is AWS's recommendation for customers who have architected databases using EBS for backups?
A. Backups to Amazon S3 be performed through the database management system.
B. Backups to AWS Storage Gateway be performed through the database management system.
C. If you take regular snapshots no further backups are required.
D. Backups to Amazon Glacier be performed through the database management system.
Answer: A
Explanation:
Data stored in Amazon EBS volumes is redundantly stored in multiple physical locations as part of normal operation of those services and at no additional charge.
However, Amazon EBS replication is stored within the same availability zone, not across multiple zones; therefore, it is highly recommended that you conduct regular snapshots to Amazon S3 for long-term data durability.
For customers who have architected complex transactional databases using EBS, it is recommended that backups to Amazon S3 be performed through the database management system so that distributed transactions and logs can be checkpointed.
AWS does not perform backups of data that are maintained on virtual disks attached to running instances on Amazon EC2.

Q287. A major finance organisation has engaged your company to set up a large data mining application. Using AWS you decide the best service for this is Amazon Elastic MapReduce(EMR) which you know uses Hadoop. Which of the following statements best describes Hadoop?
A. Hadoop is 3rd Party software which can be installed using AMI
B. Hadoop is an open source python web framework
C. Hadoop is an open source Java software framework
D. Hadoop is an open source javascript framework
Answer: C
Explanation:
Amazon EMR uses Apache Hadoop as its distributed data processing engine.
Hadoop is an open source, Java software framework that supports data-intensive distributed applications running on large clusters of commodity hardware. Hadoop implements a programming model named "MapReduce," where the data is dMded into many small fragments of work, each of which may be executed on any node in the cluster.
This framework has been widely used by developers, enterprises and startups and has proven to be a reliable software platform for processing up to petabytes of data on clusters of thousands of commodity machines.

Q288. Do Amazon EBS volumes persist independently from the running life of an Amazon EC2 instance?
A. Yes, they do but only if they are detached from the instance.
B. No, you cannot attach EBS volumes to an instance.
C. No, they are dependent.
D. Yes, they do.
Answer: D
Explanation:
An Amazon EBS volume behaves like a raw, unformatted, external block device that you can attach to a
single instance. The volume persists independently from the running life of an Amazon EC2 instance. Reference: http://docs.amazonwebservices.com/AWSEC2/latest/UserGuide/Storage.html
