Free CompTIA Network+ N10-008 Practice Question

A network technician notices that a segment of the network that connects two buildings has recently begun to experience intermittent connectivity issues and reduced throughput. The cabling used to connect these buildings is single-mode fiber-optic. The OTDR reports confirm a slight increase in signal loss over the last quarter. Which of the following is the most likely cause of the new connectivity issues experienced over this fiber-optic link?

  • Limitations inherent to multimode fiber-optic cable being used beyond its effective range.

  • Temperature fluctuations causing the single-mode fibers to expand and contract.

  • Use of incorrect transceivers for the single-mode fiber-optic cabling.

  • Dirty or damaged connectors on the fiber-optic cable.
