CompTIA Server+ SK0-005 Practice Question

An administrator must preserve a 4 KB master decryption key for at least 25 years in a vault that might outlast current storage hardware. The copy must be readable without specialized equipment, resist electromagnetic-pulse events, and remain usable even if today's storage interfaces become obsolete. Which backup media type BEST meets these requirements?

  • An LTO-9 magnetic tape cartridge stored in an off-site vault

  • An offline solid-state drive kept inside a Faraday cage

  • An encrypted object stored in a long-term cold cloud archive tier

  • A printed hard copy of the key sealed in a fire-resistant safe
