• To ensure data is available for immediate use

• To store inactive data for future reference

• To back up data daily

• To delete unnecessary data

Which of the following is a disadvantage of data archiving?

• Data is immediately available

• Data access speeds are fast

• Data is not immediately available

• Data is stored on expensive devices

What is the main goal of data backup?

• To ensure current data can be recovered

• To store data on cheaper devices

• To archive inactive data

What is a restore point?

• A type of data archiving

• A method to delete old data

• A record of a system's state at backup time

• A backup of only changed files

• Full backup

• Differential backup

• Incremental backup

• Partial backup

What is a disadvantage of a full backup?

• It only backs up changed files

• It can take a long time to restore

• It requires less storage space

• It is quick to create

Which backup type backs up files changed since the last full backup?

• Full backup

• Differential backup

• Partial backup

• Incremental backup

What is an advantage of a differential backup?

• It has a faster restore time than an incremental backup

• It requires less storage space than a full backup

• It is slower to create than a full backup

• It backs up all data files

Why might an organization perform backups more frequently than once per day?

• To delete unnecessary data

• To prevent data loss from recent changes

• To archive inactive data

• To store data on cheaper devices

What is a disadvantage of a differential backup?

• It requires less storage space than a full backup

• It backs up all data files

• It takes longer to restore files than a full backup

• It is slower to create than a full backup
