IT English Essentials: Unit 3 - Quiz 1

Why is it important to regularly backup data?

• To make the computer slower

• To prevent data loss and ensure data can be recovered in case of unexpected events.

• To confuse hackers

• To save storage space

What are the different methods of data backup?

• Automatic backup

• Local backup

• Partial backup

• Full backup, Incremental backup, Differential backup, Mirror backup, Cloud backup

Explain the process of creating a data recovery plan.

• Creating a data recovery plan involves selecting random data, skipping risk assessment, and not training employees.

• The process of creating a data recovery plan involves identifying critical data, assessing risks, developing a plan, testing the plan, and training employees.

• The process of creating a data recovery plan includes ignoring critical data, not developing a plan, and avoiding testing.

• Creating a data recovery plan consists of guessing critical data, underestimating risks, and not involving employees.

• Incompatibility with legacy systems

How can individuals ensure the security of their backed-up data?

• Never update

• Encrypt the data, use strong passwords, update regularly, store securely, use reputable services

• Use weak passwords

• Share data openly

What role does data redundancy play in backup strategies?

• Data redundancy in backup strategies increases the risk of data loss

• Data redundancy in backup strategies helps ensure data availability and reliability by providing multiple copies of the same data for recovery purposes.

• Data redundancy in backup strategies consumes less storage space

• Data redundancy in backup strategies slows down the backup process

Explain the concept of incremental backups.

• Incremental backups only backup files that have never been modified.

• Incremental backups are the same as full backups, just with a different name.

• Incremental backups only store changes made since the last backup, reducing time and storage space needed.

• Incremental backups store all data from scratch every time, leading to longer backup times.
