CompTIA Network+ (N10-008) — Question 286

Network connectivity in an extensive forest reserve was achieved using fiber optics. A network fault was detected, and now the repair team needs to check the integrity of the fiber cable. Which of the following actions can reduce repair time?

Answer options

• A. Using a tone generator and wire map to determine the fault location
• B. Using a multimeter to locate the fault point
• C. Using an OTDR in one end of the optic cable to get the fiber length information
• D. Using a spectrum analyzer and comparing the current wavelength with a working baseline

Correct answer: C

Explanation

Using an OTDR is the most effective method as it provides precise information about the fiber length and can identify the location of faults quickly. The other options, while useful, either do not specifically target fiber integrity or are less efficient in pinpointing the exact fault location in fiber optic cables.
