What is the main benefit of using snapshots?

• They allow for faster file access

• They enable easy recovery in case of data loss or corruption

• They allow for multiple versions of a file to be stored

• They improve the performance of the file system

What is a snapshot in computer science?

• A copy of a file or directory

• A copy of the entire file system at a specific point in time

• A copy of the memory of a running program

• A copy of the configuration settings of a computer

What is a data center?

• A network of computers that work together to perform a specific task

• A virtual environment for running computer programs

Which of the following is a common component of a data center?

How does block-level storage differ from file-level storage?

• Block-level storage stores data in blocks, while file-level storage stores data as files

• Block-level storage is more efficient for storing large amounts of data, while file-level storage is better for small amounts of data

• Block-level storage is more suitable for use with databases, while file-level storage is better for storing multimedia files

• Block-level storage stores data in a linear manner, while file-level storage stores data in a hierarchical manner

What is a common use case for block-level storage?

• Storing multimedia files

• Running virtual machines

• Storing large amounts of structured data, such as databases

• Backing up files

What is virtualization?

• The process of creating a virtual version of a physical object or resource

• The process of creating a physical version of a virtual object or resource

• The process of creating a backup of a physical object or resource

• The process of creating a backup of a virtual object or resource

What is a virtual machine ?

• A software implementation of a machine that executes programs like a real machine

• A hardware implementation of a machine that executes programs like a real machine

• A network implementation of a machine that executes programs like a real machine

• A virtual implementation of a machine that executes programs like a real machine
