Which of the following are advantages of using multimode fiber for an Ethernet link instead of UTP or single-mode fiber?

  • To achieve the longest distance possible for that single link.
  • To extend the link beyond 100 meters while keeping initial costs as low as possible.
  • To make use of an existing stock of laser-based SFP/SFP+ modules.
  • To make use of an existing stock of LED-based SFP/SFP+ modules.

Explanation: Multimode fiber works with LED-based transmitters rather than laser-based transmitters. Two answers mention the type of transmitters, making one of those answers correct and one incorrect.
Two answers mention distance. The answer that mentions the longest distance possible is incorrect because single-mode cables, not multimode cables, provide the longest distances. The other (correct) answer mentions the tradeoff of multimode being used for distances just longer than UTP’s 100 meter limit, while happening to use less expensive hardware than single mode.
