Question 26

You have created an AWS EC2 instance of type t2.micro through your terraform configuration file ec2.tf .
Now you want to change the instance type from t2.micro to t2.medium. Accordingly you have changed your configuration file and and ran terraform plan. After running terraform plan you check the output and saw one instance will be updated from t2.micro --> t2.medium. After this you went to grab a coffee without running terraform apply and meanwhile a member of your team changed the instance type of that EC2 instance to t2.medium from aws console. After coming to your desk you run terraform apply. What will happen?

A.The instance type will be changed to t2.micro and again will be changed to t2.medium

B.No resource will be updated and you will see the message : Apply Complete ! Resources : 0 added, 0 changed, 0 destroyed.

C.terraform apply will through an error.

D.1 resource will be updated and you will see the message : Apply Complete ! Resources : 0 added, 1 changed, 0 destroyed.

Question 27

You have multiple developers working on a terraform project (using terraform OSS), and have saved the terraform state in a remote S3 bucket . However ,team is intermittently experiencing inconsistencies in the provisioned infrastructure / failure in the code . You have traced this problem to simultaneous/concurrent runs of terraform apply command for 2/more developers . What can you do to fix this problem?

A.Use terraform workspaces feature, this will fix this problem by default , as every developer will have their own state file , and terraform will merge them on server side on its own.

B.Structure your team in such a way that only one individual will run terraform apply , everyone will just make changes and share with him. Then there will be no chance of any inconsistencies.

C.Stop using remote state , and store the developer tfstate in their own machine . Once a day , all developers should sit together and merge the state files manually , to avoid any inconsistencies.

D.Enable terraform state locking for the S3 backend using DynamoDB table. This prevents others from acquiring the lock and potentially corrupting your state.

Question 28

Which of the following value will be accepted for my_var?
1. variable "my_var"
2. {
3. type = string
4. }

A.15

B."15"

C.Both A and B

D.None of the above

Question 29

Terraform variables and outputs that set the "description" argument will store that description in the state file.

A.False

B.True

Question 30

The terraform init command is always safe to run multiple times, to bring the working directory up to date with changes in the configuration. Though subsequent runs may give errors, this command will never delete your existing configuration or state.
