JNCIA-DC: Juniper Networks Certified Associate – Data Center — Question 25

Under ideal conditions, which frequency band will have the farthest usable range?

Answer options

• A. 900 MHz
• B. 2.4 GHz
• C. 5 GHz
• D. 6 GHz

Correct answer: B

Explanation

The 2.4 GHz band has a longer range compared to higher frequency bands like 5 GHz and 6 GHz due to its better ability to penetrate obstacles and cover greater distances. While 900 MHz also offers a good range, it is not typically used for modern wireless communications compared to 2.4 GHz. The 5 GHz and 6 GHz bands, while providing higher speeds, are more limited in range due to their higher frequencies.
