Exam 200-901 topic 1 question 116 discussion

Answer is C

If speed and duplex settings are incorrect, the problem should appears all the time. During office hours, users are using the IP phones, if the application is running on the voice LAN accidentally, it will impact the quality of the voice

I think the hint here is that controllers usually doens't forward traffic on data plane. So, any cpu spike woulnd't cause any issue on the packet forwarding. Based on that my answer would be C.

Ans is C

It is possible that the issue is caused by D. Generating the logs could cause the CPU on the network controller to spike, which could lead to delays in forwarding the voice IP packets. This could result in poor quality of phone calls during the time when the script is running. However, it is also possible that the issue could be caused by other factors, such as network congestion or issues with the configuration of the voice VLAN or the speed and duplex settings. It would be useful to gather more information about the network and the script to determine the root cause of the problem.

I'd go for C since it makes sense although I doubt any one would do that in the real world. The other choice D doesn;t seems to be very relevant since the network controller is supposed to impact the control plane not the data plane, thus the data plan should still forward without interruptions/drops.

Delay & jitter are not on the 'subnet' level, which is a L3 thing. C is worded by someone who has no idea about how networks operate. It has to be D.

I’m going with D on this one.

For me it's D.

Should be C, it seems to be the more logical option

speed would case problems always, DNA doesnt control traffic, so its clearly C

The Answer is C. TCP and UDP should be separated to prevent such issues and is best practice to do so. You can bet your life savings the answer is C. lol

Answer is C.

Answer is C, it says the script is running in Voice Vlan it says in clear that script is running in Voice Vlan and the same subnet, and not Data Vlan, so if script is running in Voice Vlan, even if there is QoS, it could cause jitter and drop backets depends on traffic.

Answer is C. DNA is just the control plane, and does not have anything with the dataplane.

answer is 'C'. DNAC is a controller, control plane only. Not responsible for forwarding traffic. If DNAC running impacts voice, which is normally isolated in its own VVLAN, then DNAC must be in the VVLAN

Definitely D, on our network we avoid running scripts during day time because it might caused to increase the usage of the resources which might affect the performance of the device where you are getting the logs. C is wrong, it is not advisable to mixed up management traffic to a voice traffic, id rather have different vlan for managing the devices.
