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;
A. For all new AWS accounts there is a soft limit of 20 EC2 instances per region. You should submit the limit increase form and retry the template after your limit has been increased.
B. For all new AWS accounts there is a soft limit of 20 EC2 instances per availability zone. You should submit the limit increase form and retry the template after your limit has been increased.
C. You cannot launch more than 20 instances in your default VPC, instead reconfigure the CloudFormation template to provision the instances in a custom VPC.
D. Your CloudFormation template is configured to use the parent account and not the new account. Change the account number in the CloudFormation template and relaunch the template.

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?
A. Connect to the environment using AWS Direct Connect.
B. Assign a public IP address to your Amazon VPC Gateway.
C. Create a dedicated NAT and deploy this to the public subnet.

B. Assign a public IP address to your Amazon VPC Gateway.
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 expecting sudden 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?
A. S3 - Infrequently Accessed Storage.
B. S3 - Reduced Redundancy Storage (RRS).
C. Glacier.
D. S3 - Provisioned IOPS.
B. S3 - Reduced Redundancy Storage (RRS).
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, us-west-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.
A. Answer 1 - Us-west-2a with two EC2 instances, us-west-2b with two EC2 instances, and us-west-2c with two EC2 instances. Answer 2 - Us-west-2a with six EC2 instances, us-west-2b with six EC2 instances, and us-west-2c with no EC2 instances
B. Answer 1 - Us-west-2a with six EC2 instances, us-west-2b with six EC2 instances, and us-west-2c with no EC2 instances. Answer 2 - Us-west-2a with three EC2 instances, us-west-2b with three EC2 instances, and us-west-2c with three EC2 instances.
C. Answer 1 - Us-west-2a with three EC2 instances, us-west-2b with three EC2 instances, and us-west-2c with no EC2 instances. Answer 2 - Us-west-2a with three EC2 instances, us-west-2b with three EC2 instances, and us-west-2c with three EC2 instances.
D. Answer 1 - Us-west-2a with three EC2 instances, us-west-2b with three EC2 instances, and us-west-2c with three EC2 instances. Answer 2 - Us-west-2a with four EC2 instances, us-west-2b with two EC2 instances, and us-west-2c with two EC2 instances.
B. Answer 1 - Us-west-2a with six EC2 instances, us-west-2b with six EC2 instances, and us-west-2c with no EC2 instances. Answer 2 - Us-west-2a with three EC2 instances, us-west-2b with three EC2 instances, and us-west-2c with three EC2 instances.

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?
A. You need to update your routing table so as to provide a route out for this instance.
B. Assign an elastic IP address to the fourth instance.
C. You have not configured a NAT in the public subnet.
D. You have not configured a routable IP address in the host OS of the fourth instance.
B. Assign an elastic IP address to the fourth instance.
