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 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-
tier VPC.
The configuration is as follows:
VPC vpc-2f8t>C447

IGVV ig-2d8bc445
NACL acl-2080c448
Subnets and Route Tables:
Web server’s subnet-258Dc44d
Application server’s suDnet-248bc44c
Database server’s subnet-9189c6f9
Route Tables:
rrb-218DC449
rtb-238bc44b
Associations:
subnet-258bc44d: rtb-2i8bc449
Subnet-248DC44C rtb-238tX44b
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 designing Internet connectivity for your VPC. The Web servers must be available on the Internet. The
application must have a highly available architecture.

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
server. After authentication, each logged-in user can only access an Amazon Simple Storage Space (S3)
keyspace specific to that user.
Which two approaches can satisfy these objectives? (Choose 2 answers)

You are designing a multi-platform web application for AWS The application will run on EC2 instances and will
be accessed from PCs. tablets and smart phones Supported accessing platforms are Windows. MACOS. IOS and
Android Separate sticky session and SSL certificate setups are required for different platform types which of
the following describes the most cost effective and performance efficient architecture setup?

Your company has an on-premises multi-tier PHP web application, which recently experienced downtime due
to a large burst In web traffic due to a company announcement Over the coming days, you are expecting
similar announcements to drive similar unpredictable bursts, and are looking to find ways to quickly improve
your infrastructures ability to handle unexpected increases in traffic.
The application currently consists of 2 tiers A web tier which consists of a load balancer and several Linux
Apache web servers as well as a database tier which hosts a Linux server hosting a MySQL database.
Which scenario below will provide full site functionality, while helping to improve the ability of your
application in the short timeframe required?
