Your company has HQ in Tokyo and branch offices all over the world and is using a logistics software with a
multi-regional deployment on AWS in Japan, Europe and USA. The logistic software has a 3-tier architecture
and currently uses MySQL 5.6 for data persistence. Each region has deployed its own database
In the HQ region you run an hourly batch process reading data from every region to compute cross-regional
reports that are sent by email to all offices this batch process must be completed as fast as possible to quickly
optimize logistics how do you build the database architecture in order to meet the requirements’?

Your company currently has a 2-tier web application running in an on-premises data center. You have
experienced several infrastructure failures in the past two months resulting in significant financial losses. Your
CIO is strongly agreeing to move the application to AWS. While working on achieving buy-in from the other
company executives, he asks you to develop a disaster recovery plan to help improve Business continuity in the
short term. He specifies a target Recovery Time Objective (RTO) of 4 hours and a Recovery Point Objective
(RPO) of 1 hour or less. He also asks you to implement the solution within 2 weeks. Your database is 200GB in
size and you have a 20Mbps Internet connection. How would you do this while minimizing costs?

You are implementing AWS Direct Connect. You intend to use AWS public service end points such as Amazon
S3, across the AWS Direct Connect link. You want other Internet traffic to use your existing link to an Internet
Service Provider.
What is the way to configure AWS Direct connect for access to services such as Amazon S3?

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 are tasked with moving a legacy application from a virtual machine running Inside your datacenter to an
Amazon VPC Unfortunately this app requires access to a number of on- premises services and no one who
configured the app still works for your company. Even worse there’s no documentation for it. What will allow theapplication running inside the VPC to reach back and access its internal dependencies without being

Refer to the architecture diagram above of a batch processing solution using Simple Queue Service (SOS) to
set up a message queue between EC2 instances which are used as batch processors Cloud Watch monitors
the number of Job requests (queued messages) and an Auto Scaling group adds or deletes batch servers
automatically based on parameters set in Cloud Watch alarms. You can use this architecture to implement
which of the following features in a cost effective and efficient manner?

You have recently joined a startup company building sensors to measure street noise and air quality in urban
areas. The company has been running a pilot deployment of around 100 sensors for 3 months each sensor
uploads 1KB of sensor data every minute to a backend hosted on AWS.
During the pilot, you measured a peak or 10 IOPS on the database, and you stored an average of 3GB of
sensor data per month in the database.
The current deployment consists of a load-balanced auto scaled Ingestion layer using EC2 instances and a
PostgreSQL RDS database with 500GB standard storage.
The pilot is considered a success and your CEO has managed to get the attention or some potential investors.
The business plan requires a deployment of at least 1O0K sensors which needs to be supported by the
backend. You also need to store sensor data for at least two years to be able to compare year over yearImprovements.
To secure funding, you have to make sure that the platform meets these requirements and leaves room for
further scaling. Which setup win meet the requirements?
