b & c You must include at least one "." character. You can include only alphabetical characters after the final "." character. Example hostnames example.com test.example.com *.example.com The rule *.example.com matches test.example.com but doesn't match example.com.

A and B are Correct. To add a host header condition you enter the hostname (for example, *.example.com) with max 128 characters and Only the following wildcard characters are supported: * and ?…$$$$ is not even supported in ELB rule syntax. To add a path condition, choose Add condition, Path and enter the path pattern (for example, /img/*).

B & C Example hostnames example.com test.example.com *.example.com The rule *.example.com matches test.example.com but doesn't match example.com. Example host header condition for the AWS CLI You can specify conditions when you create or modify a rule. For more information, see the create-rule and modify-rule commands. The following condition is satisfied by requests with a host header that matches the specified string. [ { "Field": "host-header", "HostHeaderConfig": { "Values": ["*.example.com"]

I think the $ sign is typed by mistake, it should be ?. In that case, C & E are correct. B & C is wrong since web.example.com and test.example.com will both match the condition. So condition evaluate for example.com, test.example.com and default is for web.example.com

the answer will be based on how we interpret the question . What does $$$$ signify ? a real input or just a syntax which would be replaced by web and test host headers.

B&C Path rules are not necessary only host rules *. example.com and example.com

the point is, if you are considering $$$$ as a literal input , then the option is wrong. But I think the question means $$$$=test and ABC/XYZ . With *.example to com you cannot route ABC and test host header to seperate backends. I think it should not be taken literally as an input, rather a syntax showcasing in question, So the answer is C and E. * does cannot satisfy separate backend targets for ABC and test .
