💡 Hint

Common Mistakes

Using quotes around the variable name

Using a different variable name

The variable storing the cloud provider name is 'provider'. Using it without quotes prints its value.

💡 Hint

Common Mistakes

Using incorrect quotes or missing commas

Choosing the wrong providers

The list contains 'AWS' and 'Azure'. Index 1 refers to the second item, which is 'Azure'.

5fill in blank

hard

Fill all three blanks to create a dictionary mapping cloud providers to their abbreviations and print the abbreviation for Azure.

Intro to Computing

cloud_dict = [1]: [2], [3]: 'GCP'}
print(cloud_dict['Azure'])

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

A'AWS'

B'Azure'

💡 Hint

Common Mistakes

Not using quotes around keys or values

Mixing keys and values

The dictionary keys are cloud provider names as strings. The values are their abbreviations. 'Azure' key maps to 'AZR' or 'Azure' abbreviation. Here, 'AWS' and 'Azure' are keys and values respectively.

Practice

1. Which of the following is NOT one of the top three popular cloud providers?

easy

A. GCP

B. AWS

C. DigitalOcean

D. Azure

Solution

1. Step 1: Recall the top cloud providers

   The top three popular cloud providers are AWS, Azure, and GCP.

2. Step 2: Identify the option not in the top three

   DigitalOcean is a cloud provider but not among the top three popular ones.

3. Final Answer:

   DigitalOcean -> Option C

4. Quick Check:

   Top providers = AWS, Azure, GCP [OK]

Hint: Remember AWS, Azure, GCP are top three [OK]

Common Mistakes:

• Confusing smaller providers as top three
• Mixing up cloud providers with hosting services

2. Which of the following is the correct way to refer to Amazon Web Services in short?

easy

A. AWS

B. AMZ

C. AWZ

D. AWE

Solution

1. Step 1: Understand the abbreviation for Amazon Web Services

   The correct abbreviation is AWS, standing for Amazon Web Services.

2. Step 2: Check the options for the correct abbreviation

   Only AWS matches the correct abbreviation AWS.

3. Final Answer:

   AWS -> Option A

4. Quick Check:

   Amazon Web Services = AWS [OK]

Hint: AWS is the official short form for Amazon Web Services [OK]

Common Mistakes:

• Using incorrect abbreviations like AWZ or AMZ
• Confusing AWS with Amazon's marketplace

3. You want to store files in the cloud and access them from anywhere. Which service corresponds to this in AWS, Azure, and GCP respectively?

medium

A. EC2, Virtual Machines, Compute Engine

B. S3, Blob Storage, Cloud Storage

C. Lambda, Functions, Cloud Functions

D. RDS, SQL Database, Cloud SQL

Solution

1. Step 1: Identify storage services in each cloud provider

   AWS uses S3, Azure uses Blob Storage, and GCP uses Cloud Storage for file storage.

2. Step 2: Match the options with storage services

   S3, Blob Storage, Cloud Storage correctly lists the storage services for AWS, Azure, and GCP respectively.

3. Final Answer:

   S3, Blob Storage, Cloud Storage -> Option B

4. Quick Check:

   Storage services = S3, Blob Storage, Cloud Storage [OK]

Hint: Storage services: S3 (AWS), Blob (Azure), Cloud Storage (GCP) [OK]

Common Mistakes:

• Confusing compute services with storage
• Mixing up function services with storage

4. A developer tries to launch a virtual machine on Azure but uses the AWS command aws ec2 run-instances. What is the main issue?

medium

A. The command should be run in GCP console

B. The command syntax is incorrect for AWS

C. Azure does not support virtual machines

D. The command is for AWS, not Azure

Solution

1. Step 1: Understand the command context

   The command aws ec2 run-instances is specific to AWS for launching virtual machines.

2. Step 2: Identify the mismatch with Azure

   Azure uses different commands and tools; AWS commands won't work on Azure.

3. Final Answer:

   The command is for AWS, not Azure -> Option D

4. Quick Check:

   Command context must match cloud provider [OK]

Hint: Use provider-specific commands for each cloud [OK]

Common Mistakes:

• Assuming AWS commands work on Azure
• Thinking Azure lacks virtual machine support

5. You want to design a multi-cloud app that uses AWS for computing, Azure for database, and GCP for machine learning. Which approach best supports this?

hard

A. Use each cloud's native services and connect via APIs

B. Deploy the entire app only on AWS to avoid complexity

C. Use only one cloud provider to reduce costs

D. Manually copy data between clouds without automation

Solution

1. Step 1: Understand multi-cloud design

   Multi-cloud means using different providers' services together for best features.

2. Step 2: Identify best practice for integration

   Using native services and connecting them via APIs allows smooth communication and scalability.

3. Step 3: Evaluate other options

   Deploying only on one cloud or manual data copying reduces benefits or adds errors.

4. Final Answer:

   Use each cloud's native services and connect via APIs -> Option A

5. Quick Check:

   Multi-cloud = native services + API integration [OK]

Hint: Connect cloud services via APIs for multi-cloud apps [OK]

Common Mistakes:

• Trying to avoid multi-cloud complexity by using one provider
• Ignoring automation in data transfer
• Assuming manual copying is efficient
