The correct answer is A. The application is running in the Voice VLAN and causes delays and jitter in the subnet. When the log-bundle script generates and transfers large amounts of data, if that traffic is traversing the Voice VLAN (due to a misconfiguration placing the DNA Center management interface or the script's traffic on that VLAN), it consumes bandwidth and introduces congestion…
Question
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?
Options
- AThe application is running in the Voice VLAN and causes delays and jitter in the subnet.
- BThe speed and duplex settings in Cisco DNA Center are sot incorrectly, which causes the transfer
- CThe script is written in a low-level programming language where there is no memory safety.
- DGenerating the logs causes the CPU on the network controller to spike, which causes delays in

Explanation
When the log-bundle script generates and transfers large amounts of data, if that traffic is traversing the Voice VLAN (due to a misconfiguration placing the DNA Center management interface or the script's traffic on that VLAN), it consumes bandwidth and introduces congestion, causing delays and jitter that degrade real-time voice quality. Voice traffic is extremely sensitive to latency and jitter, so bulk data transfers on the same VLAN directly impair call quality. This explains why the problem only appears during business hours when calls are active.
