Your customer wishes to deploy an enterprise application to AWS which will consist of several web servers,
several application servers and a small (50GB) Oracle database information is stored, both in the database and
the file systems of the various servers. The backup system must support database recovery whole server and
whole disk restores, and individual file restores with a recovery time of no more than two hours. They have
chosen to use RDS Oracle as the database.
Which backup architecture will meet these requirements?

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?

An AWS customer is deploying an application mat is composed of an AutoScaling group of EC2 Instances.
The customers security policy requires that every outbound connection from these instances to any other
service within the customers Virtual Private Cloud must be authenticated using a unique x 509 certificate that
contains the specific instance-id.
In addition an x 509 certificates must Designed by the customer’s Key management service in order to be
trusted for authentication.
Which of the following configurations will support these requirements?

You require the ability to analyze a large amount of data, which is stored on Amazon S3 using Amazon Elastic
Map Reduce. You are using the cc2 8x large Instance type, whose CPUs are mostly idle during processing.
Which of the below would be the most cost efficient way to reduce the runtime of the job?

Your department creates regular analytics reports from your company’s log files All log data is collected in
Amazon S3 and processed by daily Amazon Elastic MapReduce (EMR) jobs that generate daily PDF reports
and aggregated tables in CSV format for an Amazon Redshift data warehouse.
Your CFO requests that you optimize the cost structure for this system.
Which of the following alternatives will lower costs without compromising average performance of the system ordata integrity for the raw data?

You currently operate a web application. In the AWS US-East region The application runs on an auto-scaled
layer of EC2 instances and an RDS Multi-AZ database Your IT security compliance officer has tasked you to
develop a reliable and durable logging solution to track changes made to your EC2.IAM And RDS resources.
The solution must ensure the integrity and confidentiality of your log dat

A large real-estate brokerage is exploring the option of adding a cost-effective location based alert to their
existing mobile application. The application backend infrastructure currently runs on AWS Users who opt in to
this service will receive alerts on their mobile device regarding real-estate otters in proximity to their location.
For the alerts to be relevant delivery time needs to be in the low minute count the existing mobile app has 5million users across the US.
Which one of the following architectural suggestions would you make to the customer?

You are the new IT architect in a company that operates a mobile sleep tracking application.
When activated at night, the mobile app is sending collected data points of 1 kilobyte every 5 minutes to your
backend.
The backend takes care of authenticating the user and writing the data points into an Amazon DynamoDB
table.
Every morning, you scan the table to extract and aggregate last night’s data on a per user basis, and store the
results in Amazon S3. Users are notified via Amazon SNS mobile push notifications that new data is available,
which is parsed and visualized by the mobile app.
Currently you have around 100k users who are mostly based out of North America.
You have been tasked to optimize the architecture of the backend system to lower cost.
What would you recommend? (Choose 2)

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?

You have a periodic Image analysis application that gets some files In Input analyzes them and tor each file
writes some data in output to a ten file the number of files in input per day is high and concentrated in a few
hours of the day.
Currently you have a server on EC2 with a large EBS volume that hosts the input data and the results it takes
almost 20 hours per day to complete the process.
What services could be used to reduce the elaboration time and improve the availability of the solution?
