Requester pays configuration in GCP - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the purpose of the Requester Pays feature in Google Cloud Storage?

Requester Pays lets the person or project requesting data pay for the data access costs, instead of the bucket owner. This helps share costs fairly when many users access the same data.

beginner

How do you enable Requester Pays on a Google Cloud Storage bucket?

You enable it by setting the bucket's billing configuration to Requester Pays using the command:
gsutil requester-pays set on gs://[BUCKET_NAME]

intermediate

What must a user do to access data from a Requester Pays bucket?

The user must specify the billing project that will pay for the access costs by adding the flag -u [PROJECT_ID] when using gsutil or setting the billing project in API requests.

intermediate

What happens if a user tries to access a Requester Pays bucket without specifying a billing project?

The request will fail with a permission error because the system does not know which project should be billed for the access.

beginner

Can Requester Pays be disabled after it is enabled on a bucket?

Yes, you can disable it anytime by running:
gsutil requester-pays set off gs://[BUCKET_NAME] which returns billing responsibility to the bucket owner.

What does enabling Requester Pays on a bucket do?

A Encrypts the bucket data automatically

B Makes the bucket owner pay for all costs

C Blocks all external access

D Makes the requester pay for data access costs

Requester Pays shifts data access costs to the requester, not the bucket owner.

Which command enables Requester Pays on a bucket?

A gsutil set billing requester-pays gs://bucket

B gsutil enable requester-pays gs://bucket

C gsutil requester-pays set on gs://bucket

D gcloud storage buckets enable-requester-pays gs://bucket

The correct gsutil command is 'requester-pays set on' followed by the bucket name.

What must a user specify to access a Requester Pays bucket?

A The billing project ID

B The bucket owner's email

C The bucket location

D The encryption key

Users must specify the billing project ID to pay for access costs.

If Requester Pays is enabled, who pays for data storage costs?

A Requester

B Bucket owner

C Google Cloud

D No one

Storage costs remain the responsibility of the bucket owner; only access costs shift to the requester.

What happens if a user accesses a Requester Pays bucket without specifying a billing project?

A Access is denied with an error

B Access is granted for free

C The bucket owner is billed

D The request is queued

Access fails because the system cannot bill any project for the request.

Explain how Requester Pays changes billing responsibility in Google Cloud Storage.

Think about who pays when you download data from a shared bucket.

Describe the steps to enable and use Requester Pays on a bucket.

Consider commands and user actions.

Practice

1. What does enabling Requester Pays on a Google Cloud Storage bucket do?

easy

A. It makes the bucket owner pay for all data access costs.

B. It disables public access to the bucket.

C. It makes the user accessing the data pay for the access costs.

D. It encrypts the data in the bucket automatically.

Solution

1. Step 1: Understand Requester Pays concept

   Requester Pays shifts the cost of data access from the bucket owner to the user who requests the data.

2. Step 2: Identify the cost responsibility

   When enabled, the user accessing the bucket pays for network and operation costs, not the owner.

3. Final Answer:

   It makes the user accessing the data pay for the access costs. -> Option C

4. Quick Check:

   Requester Pays = user pays [OK]

Hint: Requester Pays means user pays for data access costs [OK]

Common Mistakes:

• Thinking bucket owner always pays
• Confusing with access permissions
• Assuming it encrypts data

2. Which command correctly enables Requester Pays on a bucket named my-data-bucket?

easy

A. gsutil set requesterpay gs://my-data-bucket on

B. gsutil requester-pays enable gs://my-data-bucket

C. gsutil enable requester-pays gs://my-data-bucket

D. gsutil requesterpay set on gs://my-data-bucket

Solution

1. Step 1: Recall the correct gsutil syntax

   The correct command to enable Requester Pays is gsutil requesterpay set on followed by the bucket URL.

2. Step 2: Match the command with the bucket name

   gsutil requesterpay set on gs://my-data-bucket uses the exact syntax and bucket name correctly.

3. Final Answer:

   gsutil requesterpay set on gs://my-data-bucket -> Option D

4. Quick Check:

   Correct gsutil syntax = gsutil requesterpay set on gs://my-data-bucket [OK]

Hint: Use 'gsutil requesterpay set on' to enable Requester Pays [OK]

Common Mistakes:

• Using incorrect command verbs like 'enable'
• Misplacing 'requesterpay' keyword
• Wrong order of command arguments

3. Given a bucket with Requester Pays enabled, which gsutil command will successfully copy a file named data.csv from the bucket gs://example-bucket to your local machine?

medium

A. gsutil cp --requester-pays gs://example-bucket/data.csv ./

B. gsutil cp gs://example-bucket/data.csv ./

C. gsutil cp --enable-requester-pays gs://example-bucket/data.csv ./

D. gsutil cp --requesterpay gs://example-bucket/data.csv ./

Solution

1. Step 1: Understand Requester Pays access requirement

   When accessing a Requester Pays bucket, the user must include the --requester-pays flag in the gsutil command.

2. Step 2: Identify the correct flag usage

   gsutil cp --requester-pays gs://example-bucket/data.csv ./ uses the correct flag --requester-pays with the copy command.

3. Final Answer:

   gsutil cp --requester-pays gs://example-bucket/data.csv ./ -> Option A

4. Quick Check:

   Use --requester-pays flag to access Requester Pays buckets [OK]

Hint: Add --requester-pays flag to gsutil commands for Requester Pays buckets [OK]

Common Mistakes:

• Omitting the --requester-pays flag
• Using incorrect flag names
• Assuming normal commands work without flags

4. You try to download a file from a Requester Pays bucket without the --requester-pays flag and get an error. What is the most likely fix?

medium

A. Use a different gsutil version.

B. Add the --requester-pays flag to your gsutil command.

C. Change the bucket permissions to public.

D. Disable Requester Pays on the bucket.

Solution

1. Step 1: Identify cause of error

   Accessing a Requester Pays bucket without the --requester-pays flag causes permission errors because the user is not accepting cost responsibility.

2. Step 2: Apply the correct fix

   Adding the --requester-pays flag tells Google Cloud you accept the charges, fixing the error.

3. Final Answer:

   Add the --requester-pays flag to your gsutil command. -> Option B

4. Quick Check:

   Missing --requester-pays flag causes errors [OK]

Hint: Add --requester-pays flag to fix access errors [OK]

Common Mistakes:

• Trying to disable Requester Pays without permission
• Changing bucket permissions unnecessarily
• Assuming gsutil version causes this error

5. You manage a public dataset bucket with Requester Pays enabled. A user complains they cannot access data using the Google Cloud Console UI. What is the best advice to help them access the data?

hard

A. Tell them to use gsutil with the --requester-pays flag for data access.

B. Advise them to disable Requester Pays on the bucket.

C. Instruct them to request access permissions from the bucket owner.

D. Suggest they use the Cloud Console without any special flags.

Solution

1. Step 1: Understand Requester Pays impact on access methods

   Requester Pays requires users to explicitly accept cost responsibility, usually via command flags like --requester-pays or a confirmation prompt in the UI.

2. Step 2: Identify supported access methods

   While the Cloud Console UI supports Requester Pays with a billing-enabled project and charge acceptance prompt, recommend gsutil with the --requester-pays flag as a reliable alternative when facing UI access issues.

3. Final Answer:

   Tell them to use gsutil with the --requester-pays flag for data access. -> Option A

4. Quick Check:

   Use gsutil + --requester-pays for Requester Pays buckets [OK]

Hint: Use gsutil with --requester-pays for reliable access to Requester Pays buckets [OK]

Common Mistakes:

• Assuming Console UI works without project billing enabled
• Telling users to disable Requester Pays
• Confusing permissions with billing flags
