Question 61

- (Exam Topic 3)
Terraform-specific settings and behaviors are declared in which configuration block type?

A. provider
B. terraform
C. resource
D. data

Correct Answer:B
The special terraform configuration block type is used to configure some behaviors of Terraform itself, such as requiring a minimum Terraform version to apply your configuration.
Example terraform {
required_version = "> 0.12.0"
}

Correct Answer:C

Question 63

- (Exam Topic 1)
You have recently started a new job at a retailer as an engineer. As part of this new role, you have been tasked with evaluating multiple outages that occurred during peak shopping time during the holiday season. Your investigation found that the team is manually deploying new compute instances and configuring each compute instance manually. This has led to inconsistent configuration between each compute instance.
How would you solve this using infrastructure as code?

A. Implement a ticketing workflow that makes engineers submit a ticket before manually provisioning and configuring a resource
B. Implement a checklist that engineers can follow when configuring compute instances
C. Replace the compute instance type with a larger version to reduce the number of required deployments
D. Implement a provisioning pipeline that deploys infrastructure configurations committed to your version control system following code reviews

Correct Answer:D

Question 64

- (Exam Topic 4)
You need to specify a dependency manually. What resource meta-parameter can you use lo make sure Terraform respects thee dependency?
Type your answer in the field provided. The text field is not case-sensitive and all variations of the correct answer are accepted.
Solution:
depends_on

Does this meet the goal?

A. Yes
B. No

Correct Answer:A

Question 65

- (Exam Topic 4)
Talal is a DevOps engineer and he has deployed the production infrastructure using Terraform. He is using a very large configuration file to maintain and update the actual infrastructure. As the infrastructure have grown to a very complex and large, he has started experiencing slowness when he run runs terraform plan. What are the options for him to resolve this slowness?

A. Use -refresh=true flag as well as the -target flag with terraform plan in order to work around this.
B. Run terraform refresh every time before running terraform plan.
C. Break large configurations into several smaller configurations that can each be independently applied.
D. Use -refresh=false flag as well as the -target flag with terraform plan in order to work around this.

Correct Answer:CD
For larger infrastructures, querying every resource is too slow. Many cloud providers do not provide APIs to query multiple resources at once, and the round trip time for each resource is hundreds of milliseconds. On top of this, cloud providers almost always have API rate limiting so Terraform can only request a certain number of resources in a period of time. Larger users of Terraform make heavy use of the -refresh=false flag as well as the -target flag in order to work around this. In these scenarios, the cached state is treated as the record of truth.
Although 'Use -refresh=false flag as well as the -target flag with terraform plan in order to work around this.' is a solution, but its not always recommended. Instead of using -target as a means to operate on isolated portions of very large configurations, prefer instead to break large configurations into several smaller configurations that can each be independently applied. Data sources can be used to access information about resources created in other configurations, allowing a complex system architecture to be broken down into more manageable parts that can be updated independently.
Option 'Run terraform refresh every time before running terraform plan.' and 'Use -refresh=true flag as well as the -target flag with terraform plan in order to work around this.' is not correct because in both the cases terraform will query every resources of the infrastructure.
