  4. Data Integrity
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Data replication is the process of creating multiple copies of data in different locations to ensure that the data is available even if one of the copies is lost or corrupted.

Multiple choice

Which of the following is a consistency model that ensures that all reads of data from a cloud storage system return the most recent write?

  1. Strong Consistency

  2. Eventual Consistency

  3. Read-After-Write Consistency

  4. Monotonic Read Consistency
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Strong consistency is a consistency model that ensures that all reads of data from a cloud storage system return the most recent write. This means that there is no delay between when data is written to the system and when it is available to be read.

Multiple choice

What is the term used to describe the ability of a cloud storage system to ensure that data is not lost or corrupted?

  1. Data Durability

  2. Data Consistency

  3. Data Integrity

  4. Data Replication
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Data durability is the ability of a cloud storage system to ensure that data is not lost or corrupted. This is typically achieved through the use of data replication and error-correction codes.

Multiple choice

Which of the following is a type of cloud storage that is designed for storing small amounts of data that is frequently accessed?

  1. Block Storage

  2. Object Storage

  3. File Storage

  4. In-Memory Storage
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

In-memory storage is a type of cloud storage that is designed for storing small amounts of data that is frequently accessed. This type of storage is typically much faster than other types of cloud storage, but it is also more expensive.

Multiple choice

Which of the following is a type of cloud storage that is designed for storing large amounts of data that is rarely accessed?

  1. Block Storage

  2. Object Storage

  3. File Storage

  4. Archival Storage
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Archival storage is a type of cloud storage that is designed for storing large amounts of data that is rarely accessed. This type of storage is typically less expensive than other types of cloud storage, but it is also slower.

Multiple choice

Which of the following is a type of cloud storage that is designed for storing files?

  1. Block Storage

  2. Object Storage

  3. File Storage

  4. Relational Database
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

File storage is a type of cloud storage that is designed for storing files. This type of storage typically provides features such as file sharing and version control.

Multiple choice

What is the term used to describe the ability of a cloud storage system to ensure that data is written to the system in the same order in which it was received?

  1. Data Ordering

  2. Data Consistency

  3. Data Durability

  4. Data Integrity
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Data ordering is the ability of a cloud storage system to ensure that data is written to the system in the same order in which it was received. This is important for applications that require data to be processed in a specific order.

Multiple choice

Which of the following is a type of cloud storage that is designed for storing block-based data?

  1. Block Storage

  2. Object Storage

  3. File Storage

  4. Relational Database
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Block storage is a type of cloud storage that is designed for storing block-based data. This type of storage is typically used for storing operating systems and applications.

Multiple choice

What is the term used to describe the ability of a cloud storage system to ensure that data is not lost or corrupted even in the event of a hardware failure?

  1. Data Durability

  2. Data Consistency

  3. Data Integrity

  4. Data Replication
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Data durability is the ability of a cloud storage system to ensure that data is not lost or corrupted even in the event of a hardware failure. This is typically achieved through the use of redundant storage and error-correction codes.
