    Which of the following is the MOST appropriate actions to take?

    • Flip the documents face down so no one knows these documents are PII sensitive
    • Shred the documents and let the owner print the new set
    • Retrieve the documents, label them with a PII cover sheet, and return them to the printer
    • Report to the human resources manager that their personnel are violating a privacy policy
  8. Which of the following authentication concepts is a gait analysis MOST closely associated?

    • The server should connect to internal Stratum 0 NTP servers for synchronization
    • The server should connect to external Stratum 1 NTP servers for synchronization
    • The server should connect to external Stratum 1 NTP servers for synchronization
  11. When sending messages using symmetric encryption, which of the following must happen FIRST?

    • A user access the workstation registry to make unauthorized changes to enable functionality within an application
  13. An office manager found a folder that included documents with various types of data relating to corporate clients.
