A) EC2Config
B) Run Command
C) AWS Config
D) AWS Code Pipeline



2. You have are managing an application that contains Go as the front end, Mongo DB for document management and is hosted on a relevant Web server. You prebake AM l?s with the latest version of the Web server, then user the User Data section to setup the application. You now have a change to the underlying Operating system version and need to deploy that accordingly. How can this be done in the easiest way possible.

A) Create a new EBS Volume with the relevant Os patches and attach it to the EC2 instance.
B) Create a new pre-baked AM1 with the new OS and use the User Data section to deploy the application.
C) Create a Cloud formation stack with the new AM1 and then deploy the application accordingly.
D) Create an Ops work stack with the new AMi and then deploy the application accordingly. Your answer is incorrect.



3. You are working with a customer who is using Chef Configuration management in their data center. Which service is designed to let the customer leverage existing Chef recipes in AWS?

A) AWS Ops Works
B) AWS Cloud Formation
C) AWS Elastic Beanstalk
D) Amazon Simple Workflow Service



4. You have defined a Linux based instance stack in Ops work. You now want to attach a database to the Ops work stack. Which of the below is an important step to ensure that the application on the Linux instances can communicate with the database?

A) Configure SSL so that the instance can communicate with the database
B) Configure database tags for the Ops work application layer
C) Add another stack with the database layer and attach it to the application stack.
D) Add the appropriate driver packages to ensure the application can work with the database



5. 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 A/B deployment technique to migrate users over in a controlled manner while the size of the fleet remains constant over a period of 12 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?

A) Create an Auto scaling launch configuration with the new AMI. Configure the Auto Scaling group with the / new launch configuration. Use the Auto Scaling rolling updates feature to migrate to the new version.
B) Launch new Instances using the new AMI and attach them to the Auto Scaling group. Configure Elastic Load Balancing to vary the proportion of requests sent to instances running the two application versions.
C) Create an Auto scaling launch configuration with the new AMI. Configure Auto Scaling to vary the proportion of instances launched from the two launch configurations.
D) Create a load balancer. 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. Use Amazon Route53 weighted Round Robin to vary the proportion of requests sent to the load balancers.
E) Create an Auto Scaling launch configuration with the new AMI. Create an Auto Scaling group configured to use the new launch configuration and to register Instances with the same load balancer. Vary the desired capacity of each group to migrate.
