Marvis can detect bad cables easily by using cable data such as frame errors, link statistics, link errors, and traffic patterns. https://www.juniper.net/documentation/us/en/software/mist/mist-aiops/topics/concept/layer1-actions.html#:~:text=When%20you%20click%20the%20Layer,see%20on%20the%20Actions%20dashboard.

D is correct. Mist DOES NOT run any active test to determine a bad cable. Watch the entire 1 Minute provided in the link below, also in the Juniper learning portal. https://www.juniper.net/documentation/us/en/software/mist/marvis/topics/concept/layer1-actions.html

They changed the text in this document meanwhile. When I first checked it said "by performing its won cable tests.." now: "Marvis can detect bad cables easily by using cable data such as frame errors, link statistics, link errors, and traffic patterns." so yes, you could be right with D.

SNMP definitely not, because Mist is connected to the switches via pyAgent. Since Marvis uses product data for analysis, my opinion is "D" - machine learning

Hard to answer, because it monitors AP, Switch and so on. But I would say B, its a layer1 problem. https://www.juniper.net/documentation/us/en/software/mist/marvis/topics/concept/layer1-actions.html
