Answer(s): A

Explanation:

WAN 1:
Uplink Speed: 10G
Total Usage: 26.969GB Up / 1.748GB Down
Average Throughput: 353MBps Up / 23.42MBps Down Loss: 2.51%
Average Latency: 24ms Jitter: 9.5ms
WAN 2:
Uplink Speed: 1G
Total Usage: 930GB Up / 138GB Down
Average Throughput: 12.21MBps Up / 1.82MBps Down Loss: 0.01%
Average Latency: 11ms Jitter: 3.9ms
Although WAN 1 offers greater bandwidth and throughput, it exhibits higher latency and jitter, which could detract from VoIP performance. In contrast, WAN 2, despite its lower bandwidth, offers much lower latency, nearly negligible packet loss, and reduced jitter. These characteristics are essential for VoIP applications, which demand consistent and quick packet delivery.
Therefore, for VoIP communications, WAN 2 is recommended due to its enhanced stability in latency and jitter handling, which are pivotal for the clarity and reliability of voice calls. WAN 1 could be better utilized for other tasks that require high bandwidth and are less affected by latency variations, such as large-scale data transfers.
