The Guidelines for the Mark usage is ambiguous. On the Program Mark Usage Guideline it Has a Sample Business card with Two certificatins (CCNA & CCNP) with both marks in the lower left hand corner. This same document states that one mark may appear on the front of the card. In Exhibit A, Paragraph 1 it also states that, "You may only use the mark for the highest level of certification you have achieved." These two statements don't coincide with the example card given. So what is the intended meaning of this portion. Can I use CCNA & CCNP logo on the same card. Can I use CCDP & CCNP on the same card, etc.
