JNCIA-Junos: Juniper Networks Certified Associate – Junos (2024) — Question 58

Your network infrastructure transports data, voice, and video traffic. Users are complaining that voice and video calls are not performing to their expectations.
In this scenario, which technology would you implement to improve voice and video performance on your network?

Answer options

• A. NAT
• B. IPv6
• C. CoS
• D. STP

Correct answer: C

Explanation

The correct answer is C, CoS (Class of Service), which prioritizes voice and video traffic over data traffic, ensuring better performance for these applications. NAT (A) is used for IP address translation, IPv6 (B) is an addressing protocol, and STP (D) is used for preventing loops in network topology but does not specifically enhance voice and video quality.
