A company has written a script that creates a log bundle from the Cisco DNA Center every day. The script runs without error and the log bundles are produced.
However, when the script is run during business hours, people report poor voice quality of phone calls. What explains this behavior?
AThe 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.
BThe speed and duplex settings in Cisco DNA Center are set incorrectly, which causes the transfer to be too slow.
CThe script is running in the Voice VLAN and causes delays and jitter in the subnet.
DGenerating the logs causes the CPU on the network controller to spike, which causes delays in forwarding the voice IP packets.
