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
What is the correct way to configure AWS Direct connect for access to services such as Amazon S3?
You have deployed a three-tier web application in a VPC with a CIOR block of 10 0 0 0/28 You initially deploy
two web servers, two application servers, two database servers and one NAT instance tor a total of seven EC2
instances The web. Application and database servers are deployed across two availability zones (AZs). You also
deploy an ELB in front of the two web servers, and use Route53 for DNS Web (raffle gradually increases in the
first few days following the deployment, so you attempt to double the number of instances in each tier of the
application to handle the new load unfortunately some of these new instances fail to launch.

You’ve been brought in as solutions architect to assist an enterprise customer with their migration of an ecommerce platform to Amazon Virtual Private Cloud (VPC) The previous architect has already deployed a 3-
The configuration is as follows:
Subnets and Route Tables:
Web server’s subnet-258Dc44d
Application server’s suDnet-248bc44c
Database server’s subnet-9189c6f9
subnet-9189c6f9 rtb-238Dc 44b
You are now ready to begin deploying EC2 instances into the VPC Web servers must have direct access to the
internet Application and database servers cannot have direct access to the internet.
Which configuration below will allow you the ability to remotely administer your application and database
servers, as well as allow these servers to retrieve updates from the Internet?

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
the application running inside the VPC to reach back and access its internal dependencies without being
reconfigured? (Choose 3 answers)
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 ability?
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?
A corporate web application is deployed within an Amazon Virtual Private Cloud (VPC) and is connected to the
corporate data center via an iPsec VPN. The application must authenticate against the on-premises LDAP
