What is the primary purpose of data backup?

  1. To create a copy of data for safekeeping

  2. To improve data access performance

  3. To protect data from unauthorized access

  4. To facilitate data sharing

Show answer
Correct Option: A
Explanation:

Data backup is the process of creating a copy of data for safekeeping, typically in a separate location, so that it can be restored in case of data loss or corruption.

Which of the following is NOT a common type of data backup?

  1. Full backup

  2. Incremental backup

  3. Differential backup

  4. Log backup

Show answer
Correct Option: D
Explanation:

Log backup is a type of data backup that is specific to databases. It captures changes made to the database since the last backup, rather than backing up the entire database.

What is the difference between a full backup and an incremental backup?

  1. A full backup backs up all data, while an incremental backup backs up only the data that has changed since the last backup.

  2. A full backup backs up all data, while an incremental backup backs up only the data that has been deleted since the last backup.

  3. A full backup backs up all data, while an incremental backup backs up only the data that has been modified since the last backup.

  4. A full backup backs up all data, while an incremental backup backs up only the data that has been created since the last backup.

Show answer
Correct Option: A
Explanation:

A full backup backs up all data, while an incremental backup backs up only the data that has changed since the last backup. This makes incremental backups faster and more efficient than full backups, but they require a full backup to be restored.

What is the purpose of a disaster recovery plan?

  1. To outline the steps to be taken in the event of a data loss or corruption

  2. To identify the critical data and systems that need to be backed up

  3. To determine the appropriate backup and recovery strategies

  4. All of the above

Show answer
Correct Option: D
Explanation:

A disaster recovery plan outlines the steps to be taken in the event of a data loss or corruption, identifies the critical data and systems that need to be backed up, and determines the appropriate backup and recovery strategies.

Which of the following is NOT a common data backup storage medium?

  1. Hard disk drives (HDDs)

  2. Solid state drives (SSDs)

  3. Magnetic tape

  4. Cloud storage

Show answer
Correct Option: C
Explanation:

Magnetic tape is a legacy data backup storage medium that is rarely used today. It is slow, unreliable, and has a limited capacity.

What is the 3-2-1 backup rule?

  1. Keep three copies of your data, two on different media, and one offsite.

  2. Keep two copies of your data, one on a primary storage device and one on a backup device.

  3. Keep one copy of your data on a primary storage device and two copies on backup devices.

  4. Keep three copies of your data, one on a primary storage device, one on a backup device, and one in the cloud.

Show answer
Correct Option: A
Explanation:

The 3-2-1 backup rule is a best practice for data backup that recommends keeping three copies of your data, two on different media, and one offsite. This ensures that you have multiple copies of your data in case of data loss or corruption, and that at least one copy is stored in a safe location away from the primary storage location.

What is the difference between data backup and data archiving?

  1. Data backup is the process of creating a copy of data for safekeeping, while data archiving is the process of storing data for long-term retention.

  2. Data backup is the process of creating a copy of data for safekeeping, while data archiving is the process of storing data for short-term retention.

  3. Data backup is the process of creating a copy of data for safekeeping, while data archiving is the process of storing data for medium-term retention.

  4. Data backup is the process of creating a copy of data for safekeeping, while data archiving is the process of storing data for indefinite retention.

Show answer
Correct Option: A
Explanation:

Data backup is the process of creating a copy of data for safekeeping, while data archiving is the process of storing data for long-term retention. Data backup is typically used to protect data from data loss or corruption, while data archiving is used to store data that is no longer actively used but may be needed in the future.

What is the role of a backup administrator?

  1. To manage and maintain backup systems and data

  2. To develop and implement backup policies and procedures

  3. To monitor backup operations and ensure that backups are successful

  4. All of the above

Show answer
Correct Option: D
Explanation:

A backup administrator is responsible for managing and maintaining backup systems and data, developing and implementing backup policies and procedures, and monitoring backup operations to ensure that backups are successful.

Which of the following is NOT a common backup software tool?

  1. Veeam Backup & Replication

  2. Acronis Cyber Backup

  3. Carbonite

  4. Microsoft Windows Server Backup

Show answer
Correct Option: C
Explanation:

Carbonite is a cloud backup service, not a backup software tool.

What is the difference between a hot backup and a cold backup?

  1. A hot backup is a backup of data that is still being used, while a cold backup is a backup of data that is not being used.

  2. A hot backup is a backup of data that is stored on a primary storage device, while a cold backup is a backup of data that is stored on a secondary storage device.

  3. A hot backup is a backup of data that is encrypted, while a cold backup is a backup of data that is not encrypted.

  4. A hot backup is a backup of data that is compressed, while a cold backup is a backup of data that is not compressed.

Show answer
Correct Option: A
Explanation:

A hot backup is a backup of data that is still being used, while a cold backup is a backup of data that is not being used. Hot backups are typically used for data that is critical to the operation of a business, while cold backups are typically used for data that is less critical or that is not frequently accessed.

What is the purpose of a backup window?

  1. To specify the time period during which backups are allowed to run

  2. To specify the maximum amount of time that a backup can take

  3. To specify the frequency with which backups are performed

  4. All of the above

Show answer
Correct Option: A
Explanation:

A backup window is a time period during which backups are allowed to run. This is typically done to avoid interfering with normal business operations.

Which of the following is NOT a common backup verification method?

  1. Restoring a backup to a test environment

  2. Comparing the backup to the original data

  3. Using a backup verification tool

  4. Checking the backup logs

Show answer
Correct Option: D
Explanation:

Checking the backup logs is not a common backup verification method, as it does not provide a reliable way to determine whether the backup is complete and accurate.

What is the difference between a backup job and a backup policy?

  1. A backup job is a specific instance of a backup, while a backup policy is a set of rules that define how backups are performed.

  2. A backup job is a set of rules that define how backups are performed, while a backup policy is a specific instance of a backup.

  3. A backup job is a backup of data that is stored on a primary storage device, while a backup policy is a backup of data that is stored on a secondary storage device.

  4. A backup job is a backup of data that is encrypted, while a backup policy is a backup of data that is not encrypted.

Show answer
Correct Option: A
Explanation:

A backup job is a specific instance of a backup, while a backup policy is a set of rules that define how backups are performed. Backup policies typically define the frequency of backups, the type of backup (full, incremental, or differential), the data to be backed up, and the storage location for the backups.

Which of the following is NOT a common backup storage location?

  1. Local storage (e.g., hard disk drives or solid state drives)

  2. Network-attached storage (NAS)

  3. Cloud storage

  4. Tape storage

Show answer
Correct Option: D
Explanation:

Tape storage is a legacy backup storage location that is rarely used today. It is slow, unreliable, and has a limited capacity.

What is the purpose of a data recovery plan?
