Unlisted outside plant communications cable may enter and be run inside a building only under certain conditions. Which of these is one of them?
A — 50 ft maximum inside the building from the point of entrance. Unlisted outside plant cable is permitted in general building spaces only when its length from the point of entrance does not exceed 15 m (50 ft) — not in risers, ducts, plenums or other environmental-air spaces.
Finding it in the book: Chapter 8 → Article 800 (general requirements for communications systems) → 800.48. Index route: “communications circuits, unlisted cables entering buildings.”

That is one of 15. The free readiness check spreads them across the exam topics and ranks what is costing you points.
Maine runs 80 questions in 180 minutes - a brisk 2.25-minute pace. All content is NEC-technical: no state-law section on the journeyman exam.
Open book, referencing the 2023 NEC per the current Prov bulletin. The exam is written knowing you have the code - the skill being tested is finding the right section fast and applying it under the clock. That's trainable, and timed practice in the real format is how you train it.
Exam details change. Always confirm the current format, references, and code edition with the official candidate bulletin before test day.
