Developing Applications and Automating Workflows Using Cisco Platforms (DEVASC) — Question 24

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?

Answer options

• A. 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.
• B. The speed and duplex settings in Cisco DNA Center are set incorrectly, which causes the transfer to be too slow.
• C. The script is running in the Voice VLAN and causes delays and jitter in the subnet.
• D. Generating the logs causes the CPU on the network controller to spike, which causes delays in forwarding the voice IP packets.

Correct answer: C

Explanation

The correct answer is C because running the script in the Voice VLAN can create congestion, leading to delays and jitter that negatively affect voice call quality. Options A and B are less relevant as they do not directly connect to the observed voice quality issue. Option D, while plausible, is not as direct as option C regarding the specific impact of VLAN congestion on voice traffic.
