Which setup win meet the requirements?
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?
Which design would you choose to meet these requirements?
An International company has deployed a multi-tier web application that relies on DynamoDB in a single region
For regulatory reasons they need disaster recovery capability In a separate region with a Recovery Time
Objective of 2 hours and a Recovery Point Objective of 24 hours They should synchronize their data on a
regular basis and be able to provision me web application rapidly using CloudFormation. The objective is to
minimize changes to the existing web application, control the throughput of DynamoDB used for the
synchronization of data and synchronize only the modified elements.

A large real-estate brokerage is exploring the option o( 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 5
million users across the us Which one of the following architectural suggestions would you make to the
customer?

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?
What DR strategy could be used to achieve this RTO and …
An ERP application is deployed across multiple AZs in a single region. In the event of failure, the RecoveryTime Objective (RTO) must be less than 3 hours, and the Recovery Point Objective (RPO) must be 15 minutes
the customer realizes that data corruption occurred roughly 1.5 hours ago.
What DR strategy could be used to achieve this RTO and RPO in the event of this kind of failure?
How would you do this while minimizing costs?
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?
Which AWS storage and database architecture meets the r…
A 3-tier e-commerce web application is current deployed on-premises and will be migrated to AWS for greater
scalability and elasticity The web server currently shares read-only data using a network distributed file system
The app server tier uses a clustering mechanism for discovery and shared session state that depends on IP
multicast The database tier uses shared-storage clustering to provide database fall over capability, and uses
several read slaves for scaling Data on all servers and the distributed file system directory is backed up weekly
to off-site tapes

You’ve been hired to enhance the overall security posture for a very large e-commerce site They have a well
architected multi-tier application running in a VPC that uses ELBs in front of both the web and the app tier with
static assets served directly from S3 They are using a combination of RDS and DynamoOB for their dynamic
data and then archiving nightly into S3 for further processing with EMR They are concerned because they found
questionable log entries and suspect someone is attempting to gain unauthorized access.Which approach provides a cost effective scalable mitigation to this kind of attack?
How can you implement the order fulfillment process whi…
Your startup wants to implement an order fulfillment process for selling a personalized gadget that needs an
average of 3-4 days to produce with some orders taking up to 6 months you expect 10 orders per day on yourfirst day. 1000 orders per day after 6 months and 10,000 orders after 12 months. Orders coming in are checked
for consistency men dispatched to your manufacturing plant for production quality control packaging shipment
and payment processing If the product does not meet the quality standards at any stage of the process
employees may force the process to repeat a step Customers are notified via email about order status and any
critical issues with their orders such as payment failure. Your case architecture includes AWS Elastic Beanstalk
for your website with an RDS MySQL instance for customer data and orders. How can you implement the order
fulfillment process while making sure that the emails are delivered reliably?
