The original master key used to encrypt the passphrase does NOT yet exist on the system, so the encrypted passphrase is unable to be decrypted. How should the LTM Specialist resolve the master key issue? (Choose one answer)

  • A. Run the tmsh delete sys crypto master-key command
  • B. Run f5mku -K from the command line
  • C. Synchronize the device from the device group
