問題 #83 
The Terraform configuration shown in the Exhibit space on this page v/ill create a new AWS instance.
答案:B
解題說明:
Detailed Explanation:
Rationale for Correct Answer: The configuration uses a data block, not a resource block. In Terraform, a data block reads information about existing infrastructure from a provider. It does not create, update, or delete infrastructure. This data source searches for an existing AWS EC2 instance with the tag Name = web.
Analysis of Incorrect Options (Distractors):
A). True. Incorrect. A new AWS instance would be created using a resource block such as resource " aws_instance " " web " { ... }, not a data source.
Key Concept: Terraform data blocks are used to query existing infrastructure, while resource blocks manage infrastructure lifecycle.
Reference: Terraform Objective Domain: Read, Generate, and Modify Configurations
問題 #84
Which of the following should you add in the required_providers block to define a provider version constraint?
答案:B
解題說明:
Rationale for Correct Answer (B):
Provider version constraints in Terraform are specified using the version argument in the required_providers block, e.g.:
terraform {
required_providers {
aws = {
source = "hashicorp/aws"
}
}
}
This ensures Terraform always uses a specific provider version (or constraint expression).
Analysis of Incorrect Options:
A . version: Incomplete, no value specified.
C . version: 3.1: Incorrect syntax, Terraform uses = not :.
D . version - 3.1: Incorrect syntax, - is invalid here.
Key Concept:
Defining provider version constraints ensures consistent provider behavior across environments and avoids breaking changes.
Reference:
Terraform Exam Objective - Manage Terraform Resources and Providers.
問題 #85
You've just finished refactoring part of your Terraform workspace's configuration to use a module to manage some of your resources. When you plan your changes, you notice that Terraform will destroy and recreate the affected resources. Doing so could cause unintended downtime in the application your workspace manages.
What supported approach should you take to complete the refactor without destroying and recreating your resources?
答案:A
解題說明:
Detailed Explanation:
* Rationale for Correct Answer: Refactoring (like moving resources into a module) changes resource addresses. Terraform will plan destroy/create unless it knows the resources were moved . The supported mechanism is a moved block, which tells Terraform how to map the old address to the new address so it updates state without recreating resources.
* Analysis of Incorrect Options (Distractors):
* B: Incorrect. terraform console is for evaluating expressions and inspecting values; it is not a supported state editor.
* C: Incorrect. Manually editing terraform.tfstate is unsafe and not the recommended/supported approach (risk of corruption and subtle errors).
* D: Incorrect. Renaming resources in a cloud console does not update Terraform state addresses and usually doesn't solve Terraform address refactors.
* Key Concept: State-aware refactoring using moved blocks to preserve resources while changing their addresses.
Reference: Navigate Terraform State and Backends - resource addressing, state mapping, and refactoring with moved blocks.
問題 #86
How can you enable verbose logging to troubleshoot Terraform?
答案:B
解題說明:
Detailed Explanation:
* Rationale for Correct Answer: Terraform logging is enabled by setting the TF_LOG environment variable. Common values include TRACE, DEBUG, INFO, WARN, and ERROR. For example: export TF_LOG=DEBUG.
* Analysis of Incorrect Options (Distractors):
* A. Set the log level command-line flag. Incorrect. Terraform does not use a general CLI flag for verbose log level control.
* C. Set the log level in your terraform block. Incorrect. Logging is not configured in the Terraform configuration block.
* Key Concept: Terraform troubleshooting logs are controlled through environment variables.

問題 #87
What is a Terraform provider not responsible for?
答案:C
解題說明:
Rationale for Correct Answer (A):
Providers only interact with one specific platform or API. Terraform itself can work with multiple providers in one configuration, but a single provider is not responsible for provisioning across multiple cloud providers.
Analysis of Incorrect Options:
B). Managing actions to take based on resource differences: This is a provider responsibility (through the resource schema).
C). Managing resources and data sources based on an API: Correct - providers define resources/data sources and map them to API calls.
D). Understanding API interactions with a hosted service: Correct - providers encapsulate API logic to allow Terraform to manage resources.
Key Concept:
Providers are API adapters. They handle CRUD operations for resources in their own ecosystem but do not span across multiple cloud platforms.
