The correct Python code to display the value of the ‘role’ key, based on the router’s API output in JSON format, is Option B. In this option, json_data is assigned the JSON content from response.json(). Then it prints the value associated with the ‘role’ key which is nested inside ‘family’, which in turn is nested inside ‘response’. The syntax json_data['response']['family']['role'] is used to access nested dictionaries in Python. References: For an exact reference, please consult the Implementing and Operating Cisco Service Provider Network Core Technologies source documents or study guide.

 For voice networks, the minimum Signal-to-Noise Ratio (SNR) required is typically around 25 dB. The SNR is the difference between the signal strength and the noise level. Given the options, we calculate the SNR for each and find that option A provides an SNR of 24 dBm (91 dBm noise subtracted from -67 dBm signal strength), which is the closest to the required minimum SNR for voice networks. References: Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) training materials1.

 The error will be flagged when trying to add the command “monitor session 1 source interface FatEthernet0/1 tx” because there is a typo in the interface name. It should be “FastEthernet” not “FatEthernet”. In Cisco IOS, the correct syntax and spelling are crucial for the commands to be accepted and executed. Any typos or incorrect syntax will result in an error.
