Creating buckets and uploading objects in GCP - Interactive Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to create a new Cloud Storage bucket named 'my-bucket'.

GCP

from google.cloud import storage

client = storage.Client()
bucket = client.[1]('my-bucket')

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

💡 Hint

Common Mistakes

Using get_bucket instead of create_bucket will try to access an existing bucket.

list_buckets returns all buckets, not create one.

delete_bucket removes a bucket, not create it.

The create_bucket method creates a new bucket in Cloud Storage.

Complete the code to upload a file 'photo.jpg' to the bucket under the name 'images/photo.jpg'.

GCP

bucket = client.get_bucket('my-bucket')
blob = bucket.blob('[1]')
blob.upload_from_filename('photo.jpg')

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

Aimages/photo.jpg

Bphoto

Cimages_photo.jpg

Dphoto.jpg

Attempts:

3 left

💡 Hint

Common Mistakes

Using just 'photo.jpg' uploads to the root, not inside 'images' folder.

Using 'photo' misses the file extension.

Using 'images_photo.jpg' is not a valid path with folders.

The blob name is the path inside the bucket. 'images/photo.jpg' places the file in the 'images' folder.

Fix the error in the code to download the file 'images/photo.jpg' from the bucket to local file 'downloaded.jpg'.

GCP

bucket = client.get_bucket('my-bucket')
blob = bucket.blob('images/photo.jpg')
blob.[1]('downloaded.jpg')

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

Adownload_as_string

Bdownload_to_file

Cdownload_to_filename

Dupload_from_filename

Attempts:

💡 Hint

Common Mistakes

Using upload_from_filename uploads a file instead of downloading.

download_as_string returns bytes, not saving to file.

download_to_file requires a file object, not a filename string.

The correct method to download a blob to a local file is download_to_filename.

4fill in blank

hard

Fill both blanks to list all bucket names in the project.

GCP

buckets = client.[1]()
for bucket in buckets:
    print(bucket.[2])

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

Alist_buckets

Bname

Cid

Dget_bucket

Attempts:

3 left

💡 Hint

Common Mistakes

Using get_bucket tries to get one bucket, not list all.

Using 'id' prints the bucket's id, not the name.

Using 'list_bucket' (missing s) causes error.

list_buckets() returns all buckets. Each bucket's name is printed.

5fill in blank

hard

Fill all three blanks to create a bucket, upload a file, and print the public URL.

GCP

bucket = client.[1]('my-new-bucket')
blob = bucket.blob('[2]')
blob.upload_from_filename('document.pdf')
print(blob.[3])

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

Acreate_bucket

Bdocument.pdf

Cpublic_url

Dget_bucket

Attempts:

3 left

💡 Hint

Common Mistakes

Using get_bucket instead of create_bucket won't create a new bucket.

Using a wrong blob name causes upload errors.

Trying to print blob.name instead of public_url won't show the URL.

Use create_bucket to make the bucket, the blob name is the filename, and public_url gives the file's URL.

Practice

1. What is the main purpose of creating a bucket in Google Cloud Storage?

easy

A. To manage user permissions

B. To organize and store files in the cloud

C. To create databases

D. To run virtual machines

Solution

1. Step 1: Understand what a bucket is

   A bucket is a container in cloud storage used to hold files or objects.

2. Step 2: Identify the purpose of buckets

   Buckets help organize and store files safely in the cloud for easy access and management.

3. Final Answer:

   To organize and store files in the cloud -> Option B

4. Quick Check:

   Bucket = Storage container [OK]

Hint: Buckets hold files in cloud storage, not run machines [OK]

Common Mistakes:

• Confusing buckets with virtual machines
• Thinking buckets create databases
• Mixing buckets with user permission tools

2. Which command correctly creates a new bucket named my-bucket in Google Cloud Storage using the gcloud tool?

easy

A. gcloud storage buckets create my-bucket

B. gcloud create bucket my-bucket

C. gsutil mb gs://my-bucket

D. gcloud storage create-bucket my-bucket

Solution

1. Step 1: Recall the gcloud syntax for bucket creation

   The correct syntax is gcloud storage buckets create [BUCKET_NAME].

2. Step 2: Match the command with the correct syntax

   gcloud storage buckets create my-bucket matches the correct syntax exactly.

3. Final Answer:

   gcloud storage buckets create my-bucket -> Option A

4. Quick Check:

   gcloud storage buckets create = create bucket [OK]

Hint: Use 'gcloud storage buckets create' to make buckets [OK]

Common Mistakes:

• Using 'gcloud create bucket' which is invalid syntax
• Confusing gsutil command with gcloud syntax
• Adding hyphens incorrectly in command

3. What will be the result of running this command?
gsutil cp file.txt gs://example-bucket/

medium

A. Downloads file.txt from example-bucket

B. Deletes file.txt from local storage

C. Creates a new bucket named example-bucket

D. Uploads file.txt to the example-bucket in Google Cloud Storage

Solution

1. Step 1: Understand the gsutil cp command

   The gsutil cp command copies files between local and cloud storage.

2. Step 2: Analyze the command arguments

   It copies file.txt from local to the bucket gs://example-bucket/, uploading the file.

3. Final Answer:

   Uploads file.txt to the example-bucket in Google Cloud Storage -> Option D

4. Quick Check:

   gsutil cp local-to-bucket = upload [OK]

Hint: gsutil cp localfile gs://bucket = upload file [OK]

Common Mistakes:

• Thinking cp deletes local files
• Assuming it creates buckets automatically
• Confusing upload with download direction

4. You tried to upload a file using gsutil cp myfile.txt gs://my-bucket/ but got an error saying the bucket does not exist. What is the most likely fix?

medium

A. Run the command with sudo

B. Rename the file to match the bucket name

C. Create the bucket first using gsutil mb gs://my-bucket

D. Delete the file and try again

Solution

1. Step 1: Understand the error cause

   The error means the bucket my-bucket does not exist in cloud storage.

2. Step 2: Fix by creating the bucket

   You must create the bucket first using gsutil mb gs://my-bucket before uploading files.

3. Final Answer:

   Create the bucket first using gsutil mb gs://my-bucket -> Option C

4. Quick Check:

   Bucket missing? Create it first [OK]

Hint: Create bucket before upload to avoid errors [OK]

Common Mistakes:

• Trying to upload without bucket creation
• Changing file name instead of bucket
• Using sudo unnecessarily

5. You want to create a bucket named data-archive in the us-central1 region with versioning enabled to keep old versions of files. Which sequence of commands achieves this?

hard

A. gsutil mb -l us-central1 gs://data-archive && gsutil versioning set on gs://data-archive

B. gcloud storage buckets create data-archive --location=us-central1 && gcloud storage buckets update data-archive --versioning-enabled

C. gcloud storage buckets create data-archive --region=us-central1 && gcloud storage buckets enable-versioning data-archive

D. gsutil create bucket data-archive us-central1 && gsutil enable versioning gs://data-archive

Solution

1. Step 1: Create bucket with location using gsutil

   The command gsutil mb -l us-central1 gs://data-archive creates the bucket in the correct region.

2. Step 2: Enable versioning on the bucket

   The command gsutil versioning set on gs://data-archive turns on versioning to keep old file versions.

3. Final Answer:

   gsutil mb -l us-central1 gs://data-archive && gsutil versioning set on gs://data-archive -> Option A

4. Quick Check:

   Create bucket + enable versioning with gsutil [OK]

Hint: Use gsutil mb and gsutil versioning set on for versioned buckets [OK]

Common Mistakes:

• Using wrong flags like --region instead of -l
• Trying to enable versioning with wrong commands
• Mixing gcloud and gsutil commands incorrectly
