You’re running an application on-premises due to its dependency on non-x86 hardware and want
to use AWS for data backup. Your backup application is only able to write to POSIX-compatible,
block-based storage. You have 140TB of data and would like to mount it as a single folder on
your file server. Users must be able to access portions of this data while the backups are taking
place. What backup solution would be most appropriate for this use case?

Your firm has uploaded a large amount of aerial image data to S3. In the past, in your onpremises environment, you used a dedicated group of servers to batch process this data and
used RabbitMQ, an open source messaging system, to get job information to the servers. Once
processed the data would go to tape and be shipped offsite. Your manager told you to stay with
the current design, and leverage AWS archival storage and messaging services to minimize cost.
Which is correct?

You are running a successful multitier web application on AWS and your marketing department
has asked you to add a reporting tier to the application. The reporting tier will aggregate and
publish status reports every 30 minutes from user-generated information that is being stored in
your web application’s database.
You are currently running a Multi-AZ RDS MySQL instance for the database tier.
You also have implemented ElastiCache as a database caching layer between the application tier
and database tier. Please select the answer that will allow you to successfully implement the
reporting tier with as little impact as possible to your database:

A web company is looking to implement an intrusion detection and prevention system into their

You deployed your company website using Elastic Beanstalk and you enabled log file rotation to
S3. An Elastic MapReduce Job is periodically analyzing the logs on S3 to build a usage
dashboard that you share with your CIO.
You recently improved overall performance of the website using CloudFront for dynamic content
delivery and your website as the origin.
After this architectural change, the usage dashboard shows that the traffic on your website
dropped by an order of magnitude.
How do you fix your usage dashboard?

Your website is serving on-demand training videos to your workforce. Videos are uploaded
monthly in high resolution MP4 format. Your workforce is distributed globally, often on the move
and using company-provided tablets that require the HTTP Live Streaming (HLS) protocol to
watch a video. Your company has no video transcoding expertise and If required you may need
to pay for a consultant.
How do you implement the most cost-efficient architecture without compromising high availability
and quality of video delivery?
