What is the primary purpose of Cloud Storage Data Recovery?

  1. To recover data from corrupted or damaged storage devices.

  2. To restore data that has been accidentally deleted or overwritten.

  3. To protect data from unauthorized access or theft.

  4. To improve the performance of cloud storage systems.


Correct Option: B
Explanation:

Cloud Storage Data Recovery is a service that allows users to restore data that has been accidentally deleted or overwritten. It works by creating snapshots of data at regular intervals, so that users can roll back to a previous version of the data if necessary.

Which of the following is NOT a benefit of using Cloud Storage Data Recovery?

  1. It is a cost-effective way to protect data.

  2. It is easy to use and manage.

  3. It can be used to recover data from any type of storage device.

  4. It can be used to recover data that has been encrypted.


Correct Option: D
Explanation:

Cloud Storage Data Recovery cannot be used to recover data that has been encrypted. This is because the encryption key is required to decrypt the data, and this key is not stored in the cloud.

What is the maximum amount of data that can be recovered using Cloud Storage Data Recovery?

  1. 10 GB

  2. 100 GB

  3. 1 TB

  4. 10 TB


Correct Option: D
Explanation:

Cloud Storage Data Recovery can be used to recover up to 10 TB of data.

How long does it take to recover data using Cloud Storage Data Recovery?

  1. A few minutes

  2. A few hours

  3. A few days

  4. A few weeks


Correct Option: B
Explanation:

The time it takes to recover data using Cloud Storage Data Recovery depends on the amount of data being recovered and the speed of the internet connection. However, in most cases, data can be recovered within a few hours.

What is the cost of using Cloud Storage Data Recovery?

  1. It is free to use.

  2. It is a pay-as-you-go service.

  3. It is a subscription-based service.

  4. It is a one-time fee.


Correct Option: B
Explanation:

Cloud Storage Data Recovery is a pay-as-you-go service. This means that users only pay for the amount of data that they recover.

Which of the following is NOT a best practice for using Cloud Storage Data Recovery?

  1. Create regular snapshots of your data.

  2. Enable versioning for your buckets.

  3. Use strong encryption keys to protect your data.

  4. Store your data in multiple locations.


Correct Option: D
Explanation:

Storing your data in multiple locations is not a best practice for using Cloud Storage Data Recovery. This is because Cloud Storage Data Recovery can only recover data from the location where it was originally stored.

What is the recommended frequency for creating snapshots of your data?

  1. Daily

  2. Weekly

  3. Monthly

  4. Yearly


Correct Option: A
Explanation:

The recommended frequency for creating snapshots of your data is daily. This will ensure that you have a recent snapshot of your data in case you need to recover it.

What is the maximum number of versions of a file that can be stored using versioning?

  1. 10

  2. 100

  3. 1,000

  4. 10,000


Correct Option: D
Explanation:

The maximum number of versions of a file that can be stored using versioning is 10,000.

What is the recommended length for encryption keys?

  1. 128 bits

  2. 256 bits

  3. 512 bits

  4. 1024 bits


Correct Option: B
Explanation:

The recommended length for encryption keys is 256 bits. This provides a high level of security without being too computationally expensive.

What is the best way to protect your encryption keys?

  1. Store them in a password manager.

  2. Write them down on a piece of paper.

  3. Store them in a safe deposit box.

  4. Memorize them.


Correct Option: A
Explanation:

The best way to protect your encryption keys is to store them in a password manager. This will help to ensure that they are kept safe and secure.

What is the difference between a snapshot and a version?

  1. Snapshots are point-in-time copies of your data, while versions are incremental changes to your data.

  2. Snapshots are copies of your data that are stored in a different location, while versions are copies of your data that are stored in the same location.

  3. Snapshots are created manually, while versions are created automatically.

  4. Snapshots can be used to recover data that has been accidentally deleted or overwritten, while versions can be used to track changes to your data over time.


Correct Option: A
Explanation:

Snapshots are point-in-time copies of your data, while versions are incremental changes to your data. This means that snapshots can be used to recover data that has been accidentally deleted or overwritten, while versions can be used to track changes to your data over time.

What is the maximum amount of time that data can be retained using versioning?

  1. 30 days

  2. 90 days

  3. 1 year

  4. 10 years


Correct Option: D
Explanation:

The maximum amount of time that data can be retained using versioning is 10 years.

What is the best way to test your Cloud Storage Data Recovery setup?

  1. Create a test bucket and restore some data from it.

  2. Run a test restore operation on a production bucket.

  3. Read the Cloud Storage Data Recovery documentation.

  4. Contact Google Cloud Support.


Correct Option: A
Explanation:

The best way to test your Cloud Storage Data Recovery setup is to create a test bucket and restore some data from it. This will help you to ensure that your setup is working properly.

What is the recommended frequency for testing your Cloud Storage Data Recovery setup?

  1. Monthly

  2. Quarterly

  3. Annually

  4. Never


Correct Option: A
Explanation:

The recommended frequency for testing your Cloud Storage Data Recovery setup is monthly. This will help you to ensure that your setup is working properly and that you are able to recover data in the event of a disaster.

What are the limitations of Cloud Storage Data Recovery?

  1. It can only be used to recover data from Cloud Storage buckets.

  2. It can only be used to recover data that has been accidentally deleted or overwritten.

  3. It can only be used to recover data that is less than 10 TB in size.

  4. All of the above.


Correct Option: D
Explanation:

Cloud Storage Data Recovery has the following limitations:
