  • Which statement best describes how data masking differs from data deletion?
    Masking works only physically; deletion works only with software.
    Masking keeps data functional; deletion removes its path.
    Masking affects all data; deletion affects only some.
    Masking destroys data; deletion makes data fake.
  • What is the main purpose of data erasure when data reaches the end of its life cycle?
    To make the data confusing to read.
    To save space on storage devices.
    To prepare the data for backup.
    To ensure the data is permanently unrecoverable.
  • How does a degausser destroy data on storage media, compared to a shredder?
    Degaussers use physical force; shredders use electromagnetic fields.
    Degaussers alter magnetic patterns; shredders break media into particles.
    Degaussers encrypt data; shredders remove file pathways.
    Degaussers overwrite with software; shredders use heat.
  • What technique could have prevented a data breach from recoverable 'deleted' customer info?
    Data masking for testing.
    Data archiving for storage.
    Data encryption for protection.
    Data erasure for permanent destruction.
  • What is the primary purpose of data masking?
    To delete old files from a computer.
    To send files to the recycle bin.
    To permanently destroy data on a storage device.
    To replace real data with fake, functional data.
  • What do degaussers specifically use to remove data from storage media?
    Strong chemical solvents.
    High-frequency sound waves.
    Physical crushing and grinding.
    Powerful electromagnetic fields.
  • When data masking 'anonymizes' data, what does this mean?
    It makes the data completely invisible.
    It hides the original identity of the data.
    It converts the data into pictures.
    It makes the data unusable for any purpose.
  • How can you safely discard personal photos on a USB drive?
    Drag the photos to the trash icon.
    Move the USB drive to a different computer.
    Use data erasure software on the USB drive.
    Rename the photo files.
  • What happens when software permanently removes data from storage?
    The software overwrites the data with zeros and ones.
    The software hides the data in a secret folder.
    The software changes the data into a different format.
    The software creates a backup of the data.
  • What technique should a software team use to protect user data during development?
    Apply data masking to create fictitious user data.
    Send the database files to the recycle bin.
    Use a data erasure software on the database.
    Break the storage media into tiny particles.
