300-445 Question 133
Select 3An enterprise has implemented a VoIP solution for its internal communication. Users report intermittent voice quality issues, including jitter and packet loss, during peak business hours. As a network engineer, what steps should you take to assure consistent voice quality in the network?
- A
Implement Quality of Service (QoS) policies to prioritize voice traffic over other types of traffic.
- B
Use network monitoring tools to analyze real-time voice traffic performance and identify bottlenecks.
- C
Increase the size of the data center's storage to ensure sufficient capacity for voice traffic.
- D
Enable jitter buffers on voice endpoints to minimize the impact of network delays.
- E
Disable traffic policing policies to provide unlimited bandwidth for voice traffic.
Show answer and explanation
Correct answers: A, B, D
Explanation
Voice traffic in an enterprise network requires low latency, low jitter, and minimal packet loss for optimal performance. QoS ensures priority handling for voice packets, while network monitoring identifies bottlenecks that may degrade performance. Jitter buffers help mitigate the effects of variable delays. These measures collectively ensure a reliable and high-quality voice communication experience.
- A. Correct.
Correct. QoS policies are critical in prioritizing voice traffic and reducing latency, jitter, and packet loss, which directly impact voice quality.
- B. Correct.
Correct. Monitoring tools help identify issues such as high latency or congestion, allowing for targeted troubleshooting and resolution.
- C. Incorrect.
Incorrect. Increasing storage capacity in a data center does not address real-time network performance issues related to voice traffic.
- D. Correct.
Correct. Jitter buffers on voice endpoints help smooth out delays caused by jitter, ensuring more consistent audio quality.
- E. Incorrect.
Incorrect. Disabling traffic policing can lead to uncontrolled traffic and potential network congestion, negatively affecting both voice and other critical services.
