What about Article 820 NEC? I guess that all those questions about Communication circuits and CATV should not be on the Master Electrician Exam.
The NEC applies to everybody performing work covered within it's scope. Having knowledge of the NEC does not however mean that the person is competant to do the work, only that they are knowledgeable enough so that it complies with the NEC. The purpose of the NEC is to protect life and property. Nowhere does it provide the design or engineering information necessary to make anything work. You could have a completely useless installation and yet be perfectly code compliant.
Art 820 covers grounding, protection and the type of cable required for the safety of the building and it's occupants. That information is for use by anybody doing such work such as the cable companies. You took an exam that tests your knowledge of the NEC and that's why there were questions relating to Art 820. That doesn't qualify you to do any more than run cable within buildings.
Further, OSP is not within the scope of the NEC anyway until it hits the building.
