The development team has developed a new feature that uses an AWS service and wants to test it from inside a staging VPC. How should you test this feature with the fastest turnaround time?

• A.Launchan Amazon Elastic Compute Cloud (EC2) instance in the staging VPC in responseto a development request, and use configuration management to set up theapplication. Run any testing harnesses to verify application functionality andthen use Amazon Simple Notification Service (SNS) to notify the developmentteam of the results.
• B.Usean Amazon EC2 instance that frequently polls the version control system todetect the new feature, use AWS CloudFormation and Amazon EC2 user data to runany testing harnesses to verify application functionality and then use AmazonSNS to notify the development team of the results.
• C.Usean Elastic Beanstalk application that polls the version control system todetect the new feature, use AWS CloudFormation and Amazon EC2 user data to runany testing harnesses to verify application functionality and then use AmazonKinesis to notify the development team of the results.
• D.UseAWS CloudFormation to launch an Amazon EC2 instance use Amazon EC2 user data torun any testing harnesses to verify application functionality and then useAmazon Kinesis to notify the development team of the results.

You have an application consisting of a stateless web server tier running on Amazon EC2 instances behind
load balancer, and are using Amazon RDS with read replicas. Which of the following methods should you use
to implement a self-healing and cost-effective architecture? Choose 2 answers from the optionsgiven below

• A.Set up a third-party monitoring solution on a cluster of Amazon EC2 instances in order to emit custom
  Cloud Watch metrics to trigger the termination of unhealthy Amazon EC2 instances.
• B.Set up scripts on each Amazon EC2 instance to frequently send ICMP pings to the load balancer in
  order to determine which instance is unhealthy and replace it.
• C.Set up an Auto Scalinggroup for the web server tier along with an Auto Scaling policy that uses the
  Amazon RDS DB CPU utilization Cloud Watch metric to scale the instances.
• D.Set up an Auto Scalinggroup for the web server tier along with an Auto Scaling policy that uses the
  Amazon EC2 CPU utilization CloudWatch metric to scale the instances.
• E.Use a larger Amazon EC2 instance type for the web server tier and a larger DB instance type for the
  data storage layer to ensure that they don't become unhealthy.
• F.Set up an Auto Scalinggroup for the database tier along with an Auto Scaling policy that uses the
  Amazon RDS read replica lag CloudWatch metric to scale out the Amazon RDS read replicas.
• G.Use an Amazon RDS Multi-AZ deployment.

Management has reported an increase in the monthly bill from Amazon Web Services, and they are extremely concerned with this increased cost. Management has asked you to determine the exact cause of this increase.
After reviewing the billing report, you notice an increase in the data transfer cost. How can you provide management with a better insight into data transfer use?

• A.Update your Amazon CloudWatch metrics to use five-second granularity, which will give better detailed metrics that can be combined with your billing data to pinpoint anomalies.
• B.Use Amazon CloudWatch Logs to run a map-reduce on your logs to determine high usage and data transfer.
• C.Deliver custom metrics to Amazon CloudWatch per application that breaks down application data transfer into multiple, more specific data points.
  D- Using Amazon CloudWatch metrics, pull your Elastic Load Balancing outbound data transfer metrics monthly, and include them with your billing report to show which application is causing higher bandwidth usage.

You currently have the following setup in AWS
1) An Elastic Load Balancer
2) Auto Scaling Group which launches EC2 Instances
3) AMIs with your code pre-installed
You want to deploy the updates of your app to only a certain number of users. You want to have a cost-effective solution. You should also be able to revert back quickly. Which of the below solutions is the most feasible one?

• A.Create a second ELB, and a new Auto Scaling Group assigned a new Launch Configuration. Create a new AMI with the updated app. Use Route53 Weighted Round Robin records to adjust the proportion of traffic hitting the two ELBs.
• B.Create new AM Is with the new app. Then use the new EC2 instances in half proportion to the older instances.
• C.Redeploy with AWS Elastic Beanstalk and Elastic Beanstalk versions. Use Route 53 Weighted Round Robin records to adjust the proportion of traffic hitting the two ELBs
• D.Create a full second stack of instances, cut the DNS over to the new stack of instances, and change the DNS back if a rollback is needed.
