Ccp

Dls

Attempts:

💡 Hint

Common Mistakes

Using 'mb' which creates a bucket instead of listing.

The command gsutil ls lists all storage buckets in your project.

Fix the error in the command to deploy an app to App Engine.

GCP

gcloud app deploy [1]

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

Aapp.yaml

Bapp.yml

Capplication.yaml

Ddeploy.yaml

Attempts:

💡 Hint

Common Mistakes

Using incorrect file names like app.yml or deploy.yaml.

The correct configuration file for App Engine deployment is app.yaml.

Fill both blanks to create a firewall rule allowing HTTP traffic on port 80.

GCP

gcloud compute firewall-rules create allow-http --allow=[1]:[2]

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

Atcp

Budp

C80

D443

Attempts:

💡 Hint

Common Mistakes

Using UDP protocol or wrong port numbers like 443.

HTTP traffic uses TCP protocol on port 80, so the rule must allow tcp:80.

Fill all three blanks to create a GCP Pub/Sub topic and publish a message.

GCP

gcloud pubsub topics create [1]
gcloud pubsub topics publish [2] --message=[3]

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

Amy-topic

C"Hello, GCP!"

D"Test message"

Attempts:

💡 Hint

Common Mistakes

Using different topic names or missing quotes around the message.

The topic name must be consistent when creating and publishing. The message is a string like "Hello, GCP!".

Practice

1. Why do many businesses choose Google Cloud Platform (GCP) for cloud computing?

easy

A. Because it only works for small websites

B. Because it requires buying physical servers

C. Because it offers easy and scalable cloud services

D. Because it does not support data storage

Solution

1. Step 1: Understand GCP's main features

   GCP provides easy-to-use and scalable cloud services that grow with your needs.

2. Step 2: Compare options

   Options B, C, and D are incorrect because GCP does not require physical servers, supports all sizes of websites, and offers data storage.

3. Final Answer:

   Because it offers easy and scalable cloud services -> Option C

4. Quick Check:

   Easy and scalable cloud services = A [OK]

Hint: GCP is known for easy and scalable cloud services [OK]

Common Mistakes:

• Thinking GCP requires physical servers
• Believing GCP only supports small websites
• Assuming GCP lacks data storage

2. Which of the following is the correct way to describe GCP's cloud service model?

easy

A. GCP provides on-demand computing resources over the internet

B. GCP requires manual setup of physical hardware

C. GCP only offers software for local computers

D. GCP is a type of personal computer

Solution

1. Step 1: Define GCP's service model

   GCP offers cloud computing, meaning resources are available on demand via the internet.

2. Step 2: Eliminate incorrect options

   Options B, C, and D are wrong because GCP does not require physical hardware setup by users, is not local software, and is not a personal computer.

3. Final Answer:

   GCP provides on-demand computing resources over the internet -> Option A

4. Quick Check:

   On-demand internet resources = A [OK]

Hint: Cloud means on-demand internet resources, not physical hardware [OK]

Common Mistakes:

• Confusing cloud services with physical hardware
• Thinking GCP is local software only
• Misunderstanding GCP as a personal device

3. Consider this code snippet using GCP's Python client library to create a storage bucket:

from google.cloud import storage
client = storage.Client()
bucket = client.create_bucket('my-new-bucket')

What will happen when this code runs successfully?

medium

A. An error occurs because 'create_bucket' is not a valid method

B. A new storage bucket named 'my-new-bucket' is created in GCP

C. The code deletes an existing bucket named 'my-new-bucket'

D. Nothing happens because the client is not connected

Solution

1. Step 1: Understand the code purpose

   The code uses GCP's storage client to create a new bucket named 'my-new-bucket'.

2. Step 2: Verify method correctness

   The method 'create_bucket' is valid and will create the bucket if permissions and setup are correct.

3. Final Answer:

   A new storage bucket named 'my-new-bucket' is created in GCP -> Option B

4. Quick Check:

   Create bucket method creates bucket = B [OK]

Hint: create_bucket creates a new bucket if client is set up [OK]

Common Mistakes:

• Thinking create_bucket is invalid
• Confusing create with delete
• Assuming client is not connected without checking

4. You wrote this GCP command to create a virtual machine:

gcloud compute instances create my-vm --zone=us-central1-a --machine-type=n1-standard-1

But you get an error saying the zone is invalid. What is the likely problem?

medium

A. The zone name 'us-central1-a' is incorrect or misspelled

B. The machine type 'n1-standard-1' is not supported

C. The instance name 'my-vm' is too long

D. The gcloud command does not support creating instances

Solution

1. Step 1: Check the error message

   The error says the zone is invalid, so the problem relates to the zone parameter.

2. Step 2: Verify zone correctness

   Common zones are like 'us-central1-a'; a typo or wrong zone causes this error.

3. Final Answer:

   The zone name 'us-central1-a' is incorrect or misspelled -> Option A

4. Quick Check:

   Zone error means zone name issue = C [OK]

Hint: Zone errors usually mean a typo in the zone name [OK]

Common Mistakes:

• Blaming machine type for zone errors
• Thinking instance name length causes zone errors
• Assuming gcloud can't create instances

5. You want to build a website that can start small but handle millions of visitors later without changing servers. Why is GCP a good choice for this?

hard

A. Because GCP lets you buy many physical servers upfront

B. Because GCP requires manual server upgrades

C. Because GCP limits your website to a fixed size

D. Because GCP automatically scales resources as your website grows

Solution

1. Step 1: Understand website growth needs

   A website that grows needs flexible resources that can increase automatically.

2. Step 2: Match GCP features to needs

   GCP offers automatic scaling, so resources grow with traffic without manual changes.

3. Final Answer:

   Because GCP automatically scales resources as your website grows -> Option D

4. Quick Check:

   Automatic scaling fits growing websites = D [OK]

Hint: GCP auto-scales resources to handle growth smoothly [OK]

Common Mistakes:

• Thinking you must buy physical servers first
• Believing GCP limits website size
• Assuming manual upgrades are always needed
