   A network administrator is monitoring a WAN link that carries both real-time VoIP and bulk data transfers. The administrator has set a single alert threshold of 80% utilization. Recently, users reported poor VoIP quality even though the link utilization never exceeded 75%. What is the most likely reason for the alert threshold being ineffective?

   • AThe threshold is too high; it should be set to 50%
   • BThe threshold does not account for latency and jitter, which affect VoIP quality
   • CThe monitoring tool is not polling frequently enough
   • DThe link is not actually congested; the issue is with the VoIP codec
