Why it works

Answer
DA header at the top (and often bottom) identifying the document as CUI and specifying its category
A header placed at the top (and often bottom) of a CUI document that identifies it as CUI and specifies its category — the primary visual indicator that special handling rules apply.

Can CUI be sent over regular, unencrypted email?

  1. ANo — CUI must be transmitted using approved, encrypted methods
  2. BYes — as long as the recipient is a federal employee
  3. CYes — as long as the subject line includes the CUI marking
  4. DYes — provided the document is attached rather than pasted into the body
Tap the card to reveal the answer
Answer
ANo — CUI must be transmitted using approved, encrypted methods
No — CUI must be transmitted using approved, encrypted methods. Sending it over unencrypted email is a common training scenario used to test whether the rule has actually sunk in.

What is a "dissemination control" marking on a CUI document?

  1. AA marking indicating how long the information must be retained
  2. BA marking that limits who the information may be shared with, separate from the category marking
  3. CA marking showing which office originally created the document
  4. DA marking indicating the document's classification level
Tap the card to reveal the answer
Answer
BA marking that limits who the information may be shared with, separate from the category marking
A marking that limits who the information can be shared with — for example, restricting distribution to federal employees only — separate from the category marking that says what kind of CUI it is.

Who determines whether a specific piece of information qualifies as CUI?

  1. AThe individual who created the document decides
  2. BAny supervisor may designate information as CUI at their discretion
  3. CIt qualifies only if covered by a law, regulation, or government-wide policy listed in the CUI Registry
  4. DThe recipient decides based on how sensitive the content appears
Tap the card to reveal the answer
Answer
CIt qualifies only if covered by a law, regulation, or government-wide policy listed in the CUI Registry
It only qualifies if it's covered by a law, regulation, or government-wide policy listed in the CUI Registry — an individual can't decide on their own that something is CUI without that basis.
