1. You currently have an Auto scaling group that has the following settings Mm capacity - 2 Desired capacity - 2 Maximum capacity - 2 Your launch configuration has AMI?s which are based on the t2.micro instance type. The application running on these instances are now experiencing issues and you have identified that the solution is to change the Instance type of the instances running In the Auto scaling Group. Which of the below solutions will meet this demand?

A) Delete the current Launch configuration. Create a new launch configuration with the new instance type and add it to the Auto scaling Group. This will then launch the new instances.
B) Make a copy the Launch configuration. Change the Instance type In the new launch configuration. Attach that to the Auto scaling Group. Change the maximum and Desired size of the Auto scaling Group to 4. Once the new instances are launched, change the Desired and maximum size back to 2.
C) Change the Instance type in the current launch configuration. Change the Desired value of the Auto scaling Group to 4. Ensure the new Instances are launched.
D) Change the desired and maximum size of the Auto scaling Group to 4. Make a copy the Launch configuration. Change the Instance type in the new launch configuration. Attach that to the Auto scaling Group. Change the maximum and Desired size of the Auto scaling Group to 2



2. You need to investigate one of the instances which is part of your Auto scaling Group. How would you implement this.

A) Put the instance in a standby state
B) Suspend the AZR balance process so that Auto scaling will not terminate the instance
C) Put the instance in a In-service state
D) Suspend the Add To Load Balancer process



3. Which of the following services can be used to instrument Dev ops in your company?

A) All of the above
B) AWS Elastic Beanstalk
C) AWS Cloud formation
D) AWS Ops work



4. You have a legacy application running that uses an m4.large instance size and cannot scale with Auto Scaling, but only has peak performance 5% of the time. This Is a huge waste of resources and money so your Senior Technical Manager has set you the task of trying to reduce costs while still keeping the legacy application running as it should. Which of the following would best accomplish the task your manager has set you? Choose the correct answer from the options below ?

A) Use t2.nano instance and add spot instances when they are required.
B) Use two t2.nano instances that have single Root I/O Virtualizations.
C) Use a T2 burs table performance instance.
D) Use a C4.large instance with enhanced networking.



5. You have an application hosted in AWS(Amazon Web Service) , which sits on EC2 Instances behind an Elastic Load Balancer. You have added a new feature to your application and are now receiving complaints from users that the site has a slow response. Which of the below actions can you carry out to help you pinpoint the issue ?

A) Create some custom Cloud watch metrics which are pertinent to the key features of your application
B) Use Cloud watch, monitor the CPU utilization to see the times when the CPU peaked
C) Use Cloud trail to log all the API calls, and then traverse the log files to locate the issue
D) Review the Elastic Load Balancer logs
