Question No : 1 - (Topic 1)
Company B is launching a new game app for mobile devices. Users will log into the game
using their existing social media account to streamline data capture. Company B would like
to directly save player data and scoring information from the mobile app to a DynamoDS
table named Score Data When a user saves their game the progress data will be stored to
the Game state S3 bucket. What is the best approach for storing data to DynamoDB and
S3?
A. Use an EC2 Instance that is launched with an EC2 role providing access to the Score
Data DynamoDB table and the GameState S3 bucket that communicates with the
mobile app via web services.
B. Use temporary security credentials that assume a role providing access to the Score
Data DynamoDB table and the Game State S3 bucket using web identity federation.
C. Use Login with Amazon allowing users to sign in with an Amazon account providing the
mobile app with access to the Score Data DynamoDB table and the Game State S3
bucket.
D. Use an IAM user with access credentials assigned a role providing access to the Score
Data DynamoDB table and the Game State S3 bucket for distribution with the mobile app.

Your company runs a customer facing event registration site This site is built with a 3-tier
architecture with web and application tier servers and a MySQL database The application
requires 6 web tier servers and 6 application tier servers for normal operation, but can run
on a minimum of 65% server capacity and a single MySQL database. When deploying this
application in a region with three availability zones (AZs) which architecture provides high
availability?
A. A web tier deployed across 2 AZs with 3 EC2 (Elastic Compute Cloud) instances in
each AZ inside an Auto Scaling Group behind an ELB (elastic load balancer), and an
application tier deployed across 2 AZs with 3 EC2 instances in each AZ inside an Auto
Scaling Group behind an ELB. and one RDS (Relational Database Service) instance
deployed with read replicas in the other AZ.

You have an application running on an EC2 Instance which will allow users to download
flies from a private S3 bucket using a pre-assigned URL. Before generating the URL the
application should verify the existence of the file in S3.
How should the application use AWS credentials to access the S3 bucket securely?
A. Use the AWS account access Keys the application retrieves the credentials from the
source code of the application.
B. Create a IAM user for the application with permissions that allow list access to the
S3 bucket launch the instance as the IAM user and retrieve the IAM user's credentials from
the EC2 instance user data.
C. Create an IAM role for EC2 that allows list access to objects in the S3 bucket.
Launch the instance with the role, and retrieve the role's credentials from the EC2 Instance
metadata
D. Create an IAM user for the application with permissions that allow list access to the
S3 bucket. The application retrieves the IAM user credentials from a temporary directory
with permissions that allow read access only to the application user.

Question No : 4 - (Topic 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 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.
B. 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.
C. 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 IOPS Attach the volume to the instance.
D. 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.
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.

To serve Web traffic for a popular product your chief financial officer and IT director have
purchased 10 ml large heavy utilization Reserved Instances (RIs) evenly spread across
two availability zones: Route 53 is used to deliver the traffic to an Elastic Load Balancer
(ELB). After several months, the product grows even more popular and you need additional
capacity As a result, your company purchases two C3.2xlarge medium utilization Ris You
register the two c3 2xlarge instances with your ELB and quickly find that the ml large
instances are at 100% of capacity and the c3 2xlarge instances have significant capacity
that's unused Which option is the most cost effective and uses EC2 capacity most
effectively?
