Ensuring data backups for data stored on a portable device is generally considered: a. Always required. b. Necessary when the device would otherwise be the only source of hard-to-replace data, but the backup mechanism must also be secure. c. Never necessary. d. Always detrimental to security, so universally discouraged.

Respuesta :

Answer:

The answer is "Option b".

Explanation:

A data backup is a mechanism of generating a duplicate copy from your sensitive files and data like your photos, video clips, documents, and links, for example — so your data is safe and accessible when something occurs to your device, it would be the first to the provider of tough-to-replace data, and it is essential, but its recovery method must be safe, and other choices were wrong that can be described as follows:

  • In option a, It does not require always, that's why it is wrong.
  • In option c, It is wrong because data backup is necessary.
  • In option d, It doesn't provide detrimental security, that's why it is wrong.
