Explanation

Important note: The marked answer appears to be incorrect. PON (Passive Optical Network) is actually a point-to-multipoint (P2MP) topology, not point-to-point - making the correct answer B (False).

A PON uses a single OLT (Optical Line Terminal) at the service provider's end connected through passive optical splitters to multiple ONUs/ONTs (Optical Network Units/Terminals) at customer premises, forming a one-to-many tree structure. This is the defining characteristic of PON and the reason it is cost-effective - the fiber and equipment are shared across many subscribers rather than dedicated per customer. Point-to-point (P2P) access, by contrast, requires a dedicated fiber run from the provider to each individual subscriber, which is what technologies like Active Ethernet use.

Memory tip: Think of the "N" in PON - one central node fans out to Numerous customers via splitters. If it were truly P2P, there'd be no need for the passive splitters that give PON its name and architecture.

If this came from a study guide or practice exam, the answer key likely contains a typo. You may want to verify against your course textbook - PON = P2MP is a fundamental, testable networking fact.
