JNCIE-SEC: Juniper Networks Certified Expert – Security — Question 4

What are two necessary parameters for achieving a fast roaming, uninterrupted transition, and access point redundancy? (Choose two.)

Answer options

• A. deploying all access points on the same channel
• B. maintaining a noisy environment
• C. low signal-to-noise ratio
• D. radio frequency coverage overlap

Correct answer: A, D

Explanation

The correct answers are A and D because deploying all access points on the same channel allows for faster roaming as devices can switch between access points without changing channels. Additionally, overlapping radio frequency coverage ensures that there is always a signal available as the device moves. Options B and C are incorrect as a noisy environment and low signal-to-noise ratio would hinder performance and connection stability.
