A customer has established an AWS Direct Connect connection to AWS. The link is up and
routes are being advertised from the customer’s end; however the customer is unable to connect
from EC2 instances inside its VPC to servers residing in its datacenter.
Which of the following options provide a viable solution to remedy this situation? Choose 2
answers

You are designing Internet connectivity for your VPC. The Web servers must be available on the
Internet. The application must have a highly available architecture.

A newspaper organization has a on-premises application which allows the public to search Its
back catalogue and retrieve individual newspaper pages via a website written in Java. They have
scanned the old newspapers into JPEGs (approx. 17TB) and used Optical Character Recognition
(OCR) to populate a commercial search product.
The hosting platform and software are now end of life and the organization wants to migrate its
archive to AWS and produce a cost efficient architecture and still be designed for availability and
durability.
Which is the most appropriate?

Your company produces customer commissioned one-of-a-kind skiing helmets, combining high
fashion with custom technical enhancements. Customers can show off their individuality on the
ski slopes and have access to head-up-displays, GPS, rear-view cams and any other technical
Innovation they wish to embed in the helmet.
The current manufacturing process is data rich and complex, including assessments to ensure
that the custom electronics and materials used to assemble the helmets are to the highest
standards. Assessments are a mixture of human and automated assessments.
You need to add a new set of assessment to model the failure modes of the custom electronics
using GPUs with CUDA, across a cluster of servers with low latency networking.
What architecture would allow you to automate the existing process using a hybrid approach, and
ensure that the architecture can support the evolution of processes over time.

You are migrating a legacy client-server application to AWS. The application responds to a
specific DNS domain (e.g. www.example.com) and has a 2-tier architecture, with multiple
application servers and a database server. Remote clients use TCP to connect to the application
servers. The application servers need to know the IP address of the clients in order to function
properly and are currently taking that information from the TCP socket. A Multi-AZ RDS MySQL
instance will be used for the database. During the migration you can change the application code,
but you have to file a change request.
How would you implement the architecture on AWS in order to maximize scalability and high
availability?
