JNCIA-DC: Juniper Networks Certified Associate – Data Center — Question 15

What are two characteristics of the 2.4 GHz band when compared to the 5 GHz band? (Choose two.)

Answer options

• A. shorter wavelength
• B. lower frequency
• C. less non-Wi-Fi interference
• D. more congestion

Correct answer: B, C

Explanation

The correct answers are B and C because the 2.4 GHz band operates at a lower frequency, which allows it to penetrate walls better, but it also results in less non-Wi-Fi interference due to its longer range. In contrast, the 5 GHz band has a shorter wavelength and typically experiences more congestion because it supports higher data rates and is often used by many devices.
