NO.1 You have been asked to design the storage layer for an application. The application requires
disk performance of at least 100,000 IOPS in addition, the storage layer must be able to survive the
loss of an individual disk. EC2 instance, or Availability Zone without any data loss. The volume you
provide must have a capacity of at least 3 TB. Which of the following designs will meet these
objectives'?
A. Instantiate a c3 8xlarge instance in us-east-i provision 4x1TB EBS volumes, attach them to the
instance, and configure them as a single RAID 5 volume Ensure that EBS snapshots are performed
every 15 minutes.
B. Instantiate a c3 8xlarge Instance In us-east-1 Provision an AWS Storage Gateway and configure it
for 3 TB of storage and 100 000 lOPS Attach the volume to the instance.
C. Instantiate an 12 8xlarge instance in us-east-1a Create a RAID 0 volume using the four 800GB SSD
ephemeral disks provided with the instance Provision 3x1 TB EBS volumes attach them to the
instance and configure them as a second RAID 0 volume Configure synchronous, block-level
replication from the ephemeral-backed volume to the EBS-backed volume.
D. Instantiate an 12 8xlarge instance in us-east-1a create a raid 0 volume using the four 800GB SSD
ephemeral disks provide with the Instance Configure synchronous block-level replication to an
Identically configured Instance in us-east-1b.
E. Instantiate a c3 8xlarge Instance in us-east-1 Provision 3x1TB EBS volumes attach them to the
instance, and configure them as a single RAID 0 volume Ensure that EBS snapshots are performed
every 15 minutes.
Answer: E
NO.2 You need a persistent and durable storage to trace call activity 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 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.
B. Use RDS Multi-AZ with two tables, one for -Active calls" and one for -Terminated calls". In this way
the "Active calls_ table is always small and effective to access.
C. Use RDS Multi-AZ with a "CALLS" table and an Indexed "STATE* field that can be equal to 'ACTIVE"
or -TERMINATED" In this way the SOL query Is optimized by the use of the Index.
D. 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.

NO.4 You have a web application running on six Amazon EC2 instances, consuming about 45% of
resources on each instance. You are using auto-scaling to make sure that six instances are running at
all times. The number of requests this application processes is consistent and does not experience
spikes. The application is critical to your business and you want high availability at all times. You want
the load to be distributed evenly between all instances. You also want to use the same Amazon
Machine Image (AMI) for all instances. Which of the following architectural choices should you make
?
A. Deploy 2 EC2 instances in three regions and use Amazon Elastic Load Balancer.
B. Deploy 3 EC2 instances in one region and 3 in another region and use Amazon Elastic Load
Balancer.
C. Deploy 3 EC2 instances in one availability zone and 3 in another availability zone and use Amazon
Elastic Load Balancer.
D. Deploy 6 EC2 instances in one availability zone and use Amazon Elastic Load Balancer.
