Refer to the exhibit. Users at a branch office are experiencing application performance issues, poor VoIP audio quality, and slow downloads. What is the cause of the issues?

While QoS queuing issues could affect specific traffic types like VoIP, they wouldn't typically cause general 'slow downloads' and 'application performance issues' across the board unless misconfigured, and overutilization is a more fundamental underlying cause.

Incorrect interface configuration could cause connectivity loss or specific protocol failures, but it's less likely to manifest as generalized slow performance across various applications without causing complete outages for some services.

A broadcast storm typically causes severe network slowdowns or outages by consuming excessive bandwidth, which is a specific type of congestion, but 'overutilization' is a broader term encompassing any demand exceeding capacity, aligning better with general performance degradation.

The described symptoms of application performance issues, poor VoIP audio quality, and slow downloads are classic signs of network congestion or insufficient bandwidth, commonly referred to as overutilization. When a network link or device is overutilized, packets are delayed or dropped, leading to degradation of service for all traffic types.
