Your company has decided to set up a new AWS account for test and dev purposes. They already use AWS for
production, but would like a new account dedicated for test and dev so as to not accidentally break the
production environment. You launch an exact replica of your production environment using a CloudFormation
template that your company uses in production. However CloudFormation fails. You use the exact same
CloudFormation template in production, so the failure is something to do with your new AWS account. The
CloudFormation template is trying to launch 60 new EC2 instances in a single AZ. After some research you
discover that the problem is;

You work for a famous bakery who are deploying a hybrid cloud approach. Their legacy IBM AS400 servers will
remain on premise within their own datacenter however they will need to be able to communicate to the AWS
environment over a site to site VPN connection. What do you need to do to establish the VPN connection?

You work for a major news network in Europe. They have just released a new app which allows users to report
on events as and when they happen using their mobile phone. Users are able to upload pictures from the app
and then other users will be able to view these pics. Your organization expects this app to grow very quickly,
essentially doubling it’s user base every month. The app uses S3 to store the media and you are expectingsudden and large increases in traffic to S3 when a major news event takes place (as people will be uploading
content in huge numbers). You need to keep your storage costs to a minimum however and it does not matter if
some objects are lost. Which storage media should you use to keep costs as low as possible?

You have developed a new web application in us-west-2 that requires six Amazon Elastic Compute Cloud
(EC2) instances running at all times. You have three availability zones available in that region (us-west-2a, uswest-2b, and us-west-2c). You need 100 percent fault tolerance if any single Availability Zone in us-west-2
becomes unavailable. How would you do this, each answer has 2 answers, select the answer with BOTH
correct answers.

You need to add a route to your routing table in order to allow connections to the internet from your subnet.
What route should you add?

You work for a construction company that has their production environment in AWS. The production
environment consists of 3 identical web servers that are launched from a standard Amazon linux AMI using
Auto Scaling. The web servers are launched in to the same public subnet and belong to the same security
group. They also sit behind the same ELB. You decide to do some test and dev and you launch a 4th EC2
instance in to the same subnet and same security group. Annoyingly your 4th instance does not appear to have
internet connectivity. What could be the cause of this?

With which AWS orchestration service can you implement Chef recipes?

The new DB Instance that is created when you promote a Read Replica retains the backup window period.

A company has configured and peered two VPCs: VPC-1 and VPC-2. VPC-1 contains only private subnets, and
VPC-2 contains only public subnets. The company uses a single AWS Direct Connect connection and private
virtual interface to connect their on-premises network with VPC-1. Which two methods increases the fault
tolerance of the connection to VPC-1? (Choose two.)

A customer implemented AWS Storage Gateway with a gateway-cached volume at their main office. An event
takes the link between the main and branch office offline. Which methods will enable the branch office to
access their data? (Choose three.)
