1. You are using Elastic beanstalk to deploy an application that consists of a web and application server. There is a requirement to run some python scripts before the application version is deployed to the web server. Which of the following can be used to achieve this?

A) Make use of Ducker containers
B) Make use of multiple elastic beanstalk environments
C) Make use of container commands
D) Make use of custom resources



2. You have a web application composed of an Auto Scaling group of web servers behind a load balancer, and create a new AMI for each application version for deployment. You have a new version to release, and you want to use the Blue-Green deployment technique to migrate users over in a controlled manner while the size of the fleet remains constant over a period of 6 hours, to ensure that the new version is performing well. What option should you choose to enable this technique while being able to roll back easily? Choose 2 answers from the options given below. Each answer presents part of the solution(Select 2answers)

A) Configure Elastic Load Balancing to vary the proportion of requests sent to instances running the two application versions.
B) Use Amazon RouteS3 weighted Round Robin to vary the proportion of requests sent to the load balancers.
C) Create an Auto Scaling launch configuration with the new AMI to use the new launch configuration and to register instances with the existing load balancer
D) Create an Auto Scaling launch configuration with the new AMI to use the new launch configuration and to > register instances with the new load balancer



3. A company is running three production web server reserved EC2 instances with EBSbacked root volumes. These instances have a consistent Cpu load of 80%. Traffic is being distributed to these instances by an Elastic Load Balancer. They also have production and development Multi-AZ RDS My SQL databases. What recommendation would you make to reduce cost in this environment without affecting availability of mission-critical systems? Choose the correct answer from the options given below?

A) Consider using spot instances instead of reserved EC2 instances
B) Consider using on-demand instances instead of reserved EC2 instances
C) Consider removing the Elastic Load Balancer
D) Consider not using a Multi-AZ RDS deployment for the development database

D) Immutable deployments



5. You set up a web application development environment by using a third party configuration management tool to create a Docker container that Is run on local developer machines. What should you do to ensure that the web application and supporting network storage and security infrastructure does not impact your application after you deploy into AWS(Amazon Web Service) for staging and production environments?

A) Define an AWS(Amazon Web Service) Cloud Formation template to place your infrastructure Into version control and use the same template to deploy the Docker container into Elastic Beanstalk for staging and production.
B) Define an AWS(Amazon Web Service) Cloud Formation template for each stage of the application deployment lifecycle - development, staging and production and have tagging in each template to define the environment.
C) Write a script using the AWS(Amazon Web Service) SDK or CLI to deploy the application code from version control to the local development environments staging and production using AWS(Amazon Web Service) OpsWorks.
D) Because the application is inside a Docker container, there are no infrastructure differences to be taken into account when moving from the local development environments to AWS(Amazon Web Service) for staging and production.
