The application is running in the Voice VLAN and causes delays and jitter in the subnet.

The speed and duplex settings in Cisco DNA Center are sot incorrectly, which causes the transfer to be too slow.

9 The script is written in a low-level programming language where there is no memory safety. This causes a buffer overflow and disruption on the network.
