Selected Answer: A
I would go with A. There's even an example with the same script in Cisco documentation. https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/expressway/config_guide/X15-0/mra/exwy_b_mra-deployment-guide-x150/exwy_m_http-allow-list-formats.html#reference_03884D99D0DEB11F18FE1AC6231A2E1B

Selected Answer: C
The correct answer is C - Remove the line "https://myServer4/myPath4,allow,,,GET". Explanation: When configuring the HTTP Allow List on Cisco Expressway using a CSV file, all entries must conform to the expected format and avoid duplication. In this case: -The URL https://myServer4/myPath4 appears twice in the script with different rules (allow and block). -Expressway does not allow conflicting rules for the same URL path in the same HTTP Allow List. The line "https://myServer4/myPath4,allow,,,GET" conflicts with "http://myServer4/myPath4,block,,,,".

I couldn't find such a rule that says duplication of URL is not allowed. There's also an example with the same as the screenshot script here: https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/expressway/config_guide/X15-0/mra/exwy_b_mra-deployment-guide-x150/exwy_m_http-allow-list-formats.html#reference_03884D99D0DEB11F18FE1AC6231A2E1B
