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 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

keyspace specific to that user.
Which two approaches can satisfy these objectives? (Choose 2 answers)

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?

Your company produces customer commissioned one-of-a-kind skiing helmets combining nigh fashion with
custom technical enhancements Customers can show oft 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 CUD

You’re running an application on-premises due to its dependency on non-x86 hardware and want to use AWS
for data backup. Your backup application is only able to write to POSIX-compatible block-based storage. You
have 140TB of data and would like to mount it as a single folder on your file server Users must be able to
access portions of this data while the backups are taking place. What backup solution would be most
appropriate for this use case?
