CompTIA Network+ (N10-008) — Question 503

A company is designing a new complex. The primary and alternate data centers will be in separate buildings 6.2mi (10km) apart and will be connected via fiber. Which of the following types of SFP is the best choice?

Answer options

Correct answer: C

Explanation

The 10GBASE-LR is the optimal choice because it is designed for long-distance connections up to 10 kilometers, making it suitable for the 6.2 miles between the data centers. The 10GBASE-SR is intended for short distances, while 1000BASE-SX is for Gigabit connections and won't support the required 10G speed. 10000BASE-LX, although capable of longer distances, is not specifically optimized for the 10G standard like 10GBASE-LR.
