Refer to the exhibit. What is the effect of the script on the device?

A. All interfaces except GigabitEthernet2 are reset to their default configurations.

B. It replaces the entire configuration for GigabitEthernet2 on the device using RESTCONF.

C. It merges the new configuration with the existing configuration on the device using RESTCONF.

B. It manages the running configuration of the device by comparing it to the new configuration applied using NETCONF.

C. The with statement tries to connect to the device using TCP port 830 first but also tries to connect via TCP port 22.

D. Use of the with statement catches any exceptions when trying to connect to a device using NETCONF.

Refer to the exhibit. Which command prints out (44, 22) when this code is run on Python 3?
