Derivably classified documents must include both page markings and portion markings.

Derivably classified documents must include both page markings and portion markings.

• A. No
• B. Yes
• C. Only page markings
• D. Only portion markings

Answer: (B)

When deriving new classified material, it’s essential to signal sensitivity at two levels: the whole page and the individual portions that make up the content. Page markings give the overall classification for the page and set general handling rules for anyone who encounters it. But many documents mix material at different sensitivity levels, so portion markings label each paragraph or section with its specific classification. This dual approach prevents misinterpretation and accidental leakage: if you only had a page-wide mark, a highly sensitive paragraph could be treated as less sensitive, or if you only had portion marks, readers might miss the page’s overall context and allowable distribution. By marking both, you ensure readers see the highest applicable level at a glance and understand the exact sensitivity of each part, which is crucial for maintaining proper control over derivative classified information.
