After deployment of a second network link to load balance the network traffic, the quality of voice calls degrades.
The network administrator discovers the voice packets are arriving at uneven intervals that cannot be handled by the voice application buffer.
Which of the following actions will improve the quality of the voice calls?
A.
Control the attenuation of the non-voice traffic across the network links B.
Control the latency of traffic across the network links C.
Control the EMI of the multimedia traffic across the network links D.
Control the jitter of the affected traffic across the network links.

When multiple network links are deployed to load balance traffic, it is possible that the quality of voice calls degrades. This may occur because the voice packets are arriving at uneven intervals, which cannot be handled by the voice application buffer. In order to improve the quality of voice calls, the network administrator should take the following action:
D. Control the jitter of the affected traffic across the network links.
Jitter is the variation in the delay of received packets. In the context of VoIP, jitter can cause voice packets to arrive at uneven intervals, which can lead to degradation in voice quality. To control jitter, the network administrator can implement Quality of Service (QoS) mechanisms such as traffic shaping, packet prioritization, and buffer management. These mechanisms can ensure that voice packets are given priority over other types of traffic, and that they are transmitted in a timely and consistent manner.
Controlling the attenuation of non-voice traffic across the network links (A) may help to reduce overall network congestion, but it is unlikely to improve the quality of voice calls directly.
Controlling the latency of traffic across the network links (B) may help to ensure that voice packets are delivered in a timely manner, but it will not necessarily address the issue of jitter.
Controlling the EMI of multimedia traffic across the network links (C) is unlikely to be relevant in this scenario, as EMI (electromagnetic interference) typically refers to interference caused by electromagnetic fields, which is not likely to affect the transmission of network traffic.
