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?
What could be happening?
You have deployed a web application targeting a global audience across multiple AWS Regions under the
domain name.example.com. You decide to use Route53 Latency-Based Routing to serve web requests to
users from the region closest to the user. To provide business continuity in the event of server downtime you
configure weighted record sets associated with two web servers in separate Availability Zones per region.
Dunning a DR test you notice that when you disable all web servers in one of the regions Route53 does not
automatically direct all users to the other region. What could be happening? Choose 2 answers.
Which service should you use?
Your company plans to host a large donation website on Amazon Web Services (AWS). You anticipate a large
and undetermined amount of traffic that will create many database writes. To be certain that you do not drop
any writes to a database hosted on AWS. Which service should you use?
which option will support this application’s requirements?
Your company hosts a social media site supporting users in multiple countries. You have been asked to provide
a highly available design tor the application that leverages multiple regions tor the most recently accessed
content and latency sensitive portions of the wet) site The most latency sensitive component of the application
involves reading user preferences to support web site personalization and ad selection. In addition to runningyour application in multiple regions, which option will support this application’s requirements?
Which of the following options would you consider?
You are designing a data leak prevention solution for your VPC environment. You want your VPC Instances to
be able to access software depots and distributions on the Internet for product updates. The depots and
distributions are accessible via third party CONs by their URLs. You want to explicitly deny any other outbound
connections from your VPC instances to hosts on the internet.
Which of the following options would you consider?

Your system recently experienced down time during the troubleshooting process. You found that a new
administrator mistakenly terminated several production EC2 instances. Which of the following strategies will
help prevent a similar situation in the future? The administrator still must be able to:
– launch, start stop, and terminate development resources.
– launch and start production instances.
Which option below will meet the needs for your NOC members?
Your company has recently extended its datacenter into a VPC on AVVS to add burst computing capacity as
needed Members of your Network Operations Center need to be able to go to the AWS Management Console
and administer Amazon EC2 instances as necessary You don’t want to create new IAM users for each NOC
member and make those users sign in again to the AWS Management Console Which option below will meet
the needs for your NOC members?

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.

A web-startup runs its very successful social news application on Amazon EC2 with an Elastic Load Balancer,
an Auto-Scaling group of Java/Tomcat application-servers, and DynamoDB as data store. The main webapplication best runs on m2 x large instances since it is highly memory- bound Each new deployment requires
semi-automated creation and testing of a new AMI for the application servers which takes quite a while ana is
therefore only done once per week.
Recently, a new chat feature has been implemented in nodejs and wails to be integrated in the architecture.
First tests show that the new component is CPU bound Because the company has some experience with using
Chef, they decided to streamline the deployment process and use AWS Ops Works as an application life cycletool to simplify management of the application and reduce the deployment cycles.
What configuration in AWS Ops Works is necessary to integrate the new chat module in the most cost-efficient
and flexible way?

Your company previously configured a heavily used, dynamically routed VPN connection between your onpremises data center and AWS. You recently provisioned a DirectConnect connection and would like to start
using the new connection. After configuring DirectConnect settings in the AWS Console, which of the following
options win provide the most seamless transition for your users?
