A. Make sure if distribution is RTMP distribution.
B. Make sure if delimiter character between query string parameters is a “&” character.
C. Check if Parameters names & values are in same case.
D. Make sure if delimiter character between query string parameters is a “/” character.
E. Make sure if distribution is Web distribution.
F. Check only that the query parameter names are in the same case

Correct Answer – B, C, E

- Option A is incorrect as CloudFront Query String Forwarding does not support RTMP distribution.
- Option D is incorrect as Delimiter Character should be always &, not \ character.
- Option F is incorrect as in case of Parameters in query string, both name & values are case sensitive.
