Examine the following Python script that uses the netmiko library to send configuration commands to a Cisco IOS-XE device:
```python
from netmiko import ConnectHandler
device = { 'device_type': 'cisco_ios', 'ip': '192.168.1.1', 'username': 'admin', 'password': 'cisco',
}
connection = ConnectHandler(**device) config_commands = [ 'interface GigabitEthernet1/0/1', 'description Link to Core', 'ip address 10.1.1.1 255.255.255.0', 'no shutdown'
]
output = connection.send_config_set(config_commands)
print(output)
connection.disconnect() ```
What is the purpose of this script?
⚠ Common exam trap
Cisco often tests the distinction between `send_command()` (for show commands) and `send_config_set()` (for configuration commands), leading candidates to mistakenly think the script retrieves the running config when it actually applies changes.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
It configures interface GigabitEthernet1/0/1 with a description, IP address, and enables it.
The script uses Netmiko's `send_config_set()` method to push a list of configuration commands to the device. The commands configure interface GigabitEthernet1/0/1 with a description, assign an IP address, and issue `no shutdown` to enable the interface. This matches option B exactly.

Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
It retrieves the running configuration of the device.
Why it's wrong here
send_config_set is used for sending configuration commands, not retrieving config.
- ✓
It configures interface GigabitEthernet1/0/1 with a description, IP address, and enables it.
Why this is correct
The commands configure the interface as described.
- ✗
It saves the configuration to the startup configuration.
Why it's wrong here
No write memory command is included in the config_commands list.
