Practice - 5 Tasks

1fill in blank

easy

Complete the command to list all resources in the Terraform state.

Terraform

terraform state [1]

Drag options to blanks, or click blank then click option'

Ainit

Blist

Capply

Dshow

💡 Hint

Common Mistakes

Using 'show' instead of 'list' to view resources

Using 'apply' which changes infrastructure

Using 'init' which initializes Terraform

The terraform state list command shows all resources tracked in the current Terraform state.

2fill in blank

Complete the command to list resources in a specific Terraform workspace.

Terraform

terraform workspace select [1] && terraform state list

Drag options to blanks, or click blank then click option'

Aprod

Bdefault

Cinit

Dplan

Attempts:

💡 Hint

Common Mistakes

Using 'init' or 'plan' as workspace names

Not selecting a workspace before listing state

Selecting the workspace prod before listing state shows resources in that workspace.

3fill in blank

hard

Fix the error in the command to list resources with a filter prefix.

Terraform

terraform state list [1]

Drag options to blanks, or click blank then click option'

A-filter=aws_instance

B-state=aws_instance

Caws_instance

D-target=aws_instance

Attempts:

3 left

💡 Hint

Common Mistakes

Using unsupported flags like '-filter' or '-state'

Using '-target' which is for apply, not list

The terraform state list command accepts a prefix filter directly as an argument, like aws_instance.

4fill in blank

hard

Fill both blanks to list resources filtered by prefix and output to a file.

Terraform

terraform state list [1] > [2]

Drag options to blanks, or click blank then click option'

Aaws_s3_bucket

Bresources.txt

Cterraform.tfstate

Doutput.log

Attempts:

3 left

💡 Hint

Common Mistakes

Redirecting output to the state file itself

Using wrong resource prefixes

Filtering by aws_s3_bucket lists only those resources, and redirecting output to resources.txt saves the list.

5fill in blank

hard

Fill all three blanks to list resources, filter by prefix, and select a workspace.

Terraform

terraform workspace select [1] && terraform state list [2] > [3]

Drag options to blanks, or click blank then click option'

Adev

Baws_lambda_function

Clambda_resources.txt

Dprod

Attempts:

3 left

💡 Hint

Common Mistakes

Mixing workspace names and file names

Using unsupported flags in the list command

Selecting the dev workspace, listing resources filtered by aws_lambda_function, and saving output to lambda_resources.txt is a common workflow.

Practice

1. What does the terraform state list command do?

easy

A. It destroys all resources in the state.

B. It applies changes to the infrastructure.

C. It initializes the Terraform working directory.

D. It shows all resources managed by Terraform in the current state.

Solution

1. Step 1: Understand the purpose of terraform state list

   This command lists all resources that Terraform currently manages in its state file.

2. Step 2: Compare with other Terraform commands

   Other commands like apply, init, and destroy perform different actions, not listing resources.

3. Final Answer:

   It shows all resources managed by Terraform in the current state. -> Option D

4. Quick Check:

   List resources = D [OK]

Hint: Remember: 'state list' shows current managed resources [OK]

Common Mistakes:

• Confusing 'state list' with 'apply' or 'destroy'
• Thinking it initializes Terraform
• Assuming it modifies resources

2. Which of the following is the correct syntax to list all resources in the Terraform state?

easy

A. terraform list state

B. terraform state list

C. terraform show state list

D. terraform state show list

Solution

1. Step 1: Recall the correct command structure

   The correct command to list resources is terraform state list.

2. Step 2: Identify incorrect syntax

   Options B, C, and D mix command parts incorrectly and will cause errors.

3. Final Answer:

   terraform state list -> Option B

4. Quick Check:

   Correct syntax = A [OK]

Hint: Command order: terraform + state + list [OK]

Common Mistakes:

• Swapping 'state' and 'list' order
• Adding extra words like 'show'
• Using unsupported command combinations

3. Given the following Terraform state list output:
module.network.aws_vpc.main
module.network.aws_subnet.public
module.compute.aws_instance.web
What will terraform state list module.network.aws_subnet.public display?

medium

A. module.network.aws_subnet.public

B. module.compute.aws_instance.web

C. module.network.aws_vpc.main

D. No output

Solution

1. Step 1: Understand filtering by resource name

   Using terraform state list with a resource name filters the output to matching resources.

2. Step 2: Match the exact resource path

   The command matches module.network.aws_subnet.public exactly, so it will output that line.

3. Final Answer:

   module.network.aws_subnet.public -> Option A

4. Quick Check:

   Filtered list = C [OK]

Hint: Filter by full resource path to get exact match [OK]

Common Mistakes:

• Expecting all resources to show
• Confusing module paths
• Assuming no output if filter is used

4. You run terraform state list module.app.aws_instance.web but get no output, even though you expect the resource to exist. What is the most likely cause?

medium

A. Terraform state list command does not support filtering.

B. Terraform state file is empty and no resources exist.

C. The resource name or module path is incorrect or misspelled.

D. You need to run terraform apply first.

Solution

1. Step 1: Check the resource path correctness

   If no output appears, the resource path or name likely does not match any resource in the state.

2. Step 2: Understand filtering behavior

   The terraform state list command supports filtering by resource name or module path.

3. Final Answer:

   The resource name or module path is incorrect or misspelled. -> Option C

4. Quick Check:

   Incorrect path = B [OK]

Hint: Check spelling and module path carefully when filtering [OK]

Common Mistakes:

• Assuming filtering is unsupported
• Thinking state file is always empty
• Believing apply is needed to list state

5. You want to list all resources managed by Terraform inside the module database only. Which command will correctly show this filtered list?

hard

A. terraform state list module.database

B. terraform state list database

C. terraform state list module.database.*

D. terraform state list module/database

Solution

1. Step 1: Understand module path filtering

   To filter resources inside a module, use the full module path prefix like module.database.

2. Step 2: Check command syntax

   terraform state list module.database uses the correct prefix without extra characters. terraform state list module.database.* uses a wildcard which is not supported in this command.

3. Final Answer:

   terraform state list module.database -> Option A

4. Quick Check:

   Filter by module prefix = A [OK]

Hint: Use full module path prefix without wildcards to filter [OK]

Common Mistakes:

• Using wildcards which are unsupported
• Omitting 'module.' prefix
• Using partial or incorrect module names
