You have an Auto Sealing group of Instances that processes messages from an Amazon Simple Queue Service (SQS)
queue. The group scales on the size of the queue. Processing Involves calling a third-party web service. The web service
is complaining about the number of failed and repeated calls it is receiving from you. You have noticed that when the
group scales in, instances are being terminated while they are processing. What cost-effective solution can you use to
reduce the number of incomplete process attempts?
Which two of the following approaches should you use?
Your mobile application includes a photo-sharing service that is expecting tens of thousands of users at launch. You will
leverage Amazon Simple Storage Service (S3) for storage of the user Images, and you must decide how to authenticate
and authorize your users for access to these images. You also need to manage the storage of these images. Which two

You are doing a load testing exercise on your application hosted on AWS. While testing your Amazon RDS MySQL DB
instance, you notice that when you hit 100% CPU utilization on it, your application becomes non- responsive. Your
application is read-heavy. What are methods to scale your data tier to meet the application’s needs? (Choose three.)

You are administering a continuous integration application that polls version control for changes and then launches new
Amazon EC2 instances for a full suite of build tests. What should you do to ensure the lowest overall cost while being
able to run as many tests in parallel as possible?
how many Amazon EC2 instances are running at the time?
You are using Elastic Beanstalk to manage your e-commerce store. The store is based on an open source e- commerce
platform and is deployed across multiple instances in an Auto Scaling group. Your development team often creates new
“extensions” for the e-commerce store. These extensions include PHP source code as well as an SQL upgrade script
used to make any necessary updates to the database schema. You have noticed that some extension deployments fail
due to an error when running the SQL upgrade script. After further investigation, you realize that this is because the SQL
script is being executed on all of your Amazon EC2 instances. How would you ensure that the SQL script is only executed
once per deployment regardless of how many Amazon EC2 instances are running at the time?

Your current log analysis application takes more than four hours to generate a report of the top 10 users of your web
application. You have been asked to implement a system that can report this information in real time, ensure that the
report is always up to date, and handle increases in the number of requests to your web application. Choose the option
that is cost-effective and can fulfill the requirements.
What process should you use to help mitigate the cost?
After reviewing the last quarter’s monthly bills, management has noticed an increase in the overall bill from Amazon. After
researching this increase in cost, you discovered that one of your new services is doing a lot of GET Bucket API calls to
Amazon S3 to build a metadata cache of all objects in the applications bucket. Your boss has asked you to come up with
a new cost-effective way to help reduce the amount of these new GET Bucket API calls. What process should you use
to help mitigate the cost?

As part of your continuous deployment process, your application undergoes an I/O load performance test before it is
deployed to production using new AMIs. The application uses one Amazon Elastic Block Store (EBS) PIOPS volume per
instance and requires consistent I/O performance. Which of the following must be carried out to ensure that I/O load
performance tests yield the correct results in a repeatable manner?
Which of the following should you do?
Your development team wants account-level access to production instances in order to do live debugging of a highly
secure environment. Which of the following should you do?
