All slides in a slide deck may carry the same banner marking throughout the presentation. Is this statement true or false?

The statement is true because all slides in a slide deck can uniformly carry the same banner marking if the entire presentation contains similar content that warrants that specific classification. Consistency in marking helps maintain clarity and prevents any potential confusion for those reviewing the material. Each slide's content is assessed to determine if it aligns with the classification level indicated by the marking; therefore, if all slides bear the same classification due to their shared sensitivity level, using the same banner marking throughout is appropriate and acceptable. This standard practice not only reinforces the security of classified information but also contributes to a streamlined and professional appearance in presentations.
