Cisco 300-810 Online Access

These two options are the correct rules to configure in the Unity Connection restriction table to block all calls to international phone numbers and numbers that contain 10 digits and begin with 0. The rules use wildcard characters to match any number that meets the criteria. The ? character matches any single digit, while the X character matches any single digit except 0. Therefore, 0??? blocks any number that starts with 0 and has nine more digits, while 0XXXXXXXXX blocks any number that starts with 0 and has nine more digits that are not 0.

The other options are incorrect. A.9! matches any number that starts with 9 and has one or more digits after it, which is not the requirement. D.9* matches any number that starts with 9, which is also not the requirement. E.0-9* matches any number that starts with a digit from 0 to 9, which is too broad and would block valid numbers as well. References:
