Exam 350-401 topic 1 question 351 discussion

A. network_device_list(dnac[host], dnac[username],dnac[password]) login = dnac_login(dnac) print(dnac_devices) B. login = dnac_login(dnac[host], dnac[username], dnac[password]) network_device_list(dnac, login) print(dnac_devices) C. login = dnac_login(dnac[host], dnac[username], dnac[password]) network_device_list(dnac, login) for item in dnac_devices: print(dnac_devices.item) D. network_device_list(dnac[host], dnac[username], dnac[password]) login = dnac_login(dnac) for item in dnac_devices: print(dnac_devices.item)

The correct answer is: B

It´s B We need to log in first to get the token so we proves we are authorized to access the Cisco DNA Center. C is wrong, the line "for item in dnac_devices: print(dnac_devices.item)" dosen´t correctly print the items in the dnac_devices table. The PrettyTable should be printed directly.

Point. login = token. got token by function dnac_login(parameter host,username and password). got device list by function network_device_list(parameter dnac and token). got display by function print(dataset dnac_devices). no need for loop, that is what the pretty table is for. no "item" under dnac_devices function. keyword = login -> network_device_list -> print.

token = dnac_login(dnac['host'], dnac['username'], dnac['password']) network_device_list(dnac, token) print(dnac_devices)

This question was literally pulled out of the OCG book.

login = dnac_login(dnac["host"], dnac["username"], dnac["password"]) network_device_list(dnac, login) print(dnac_devices) https://github.com/bigevilbeard/dnac-device-info/blob/master/get_dnac_devices.py

Without Python background, how can we know the answer?

no need for loop, that is what the pretty table is for

It should be B

B. There is no "item" under dnac_devices

xziomal9 is right. B is the correct answer.
