I guess your colleague needs to wait until a new CCSA exam version will be released. Related to the official CCSA Q&A there is no way to take the same exam again once you have passed it. The only possible way that is mentioned is...
How do I renew my certification?
If you want to renew a certification, you can take the same exam for a later version, or you can complete two Continuing Education Credits.
But as the second option (continuing education credits) is not available anymore it seems like your colleague has to wait. Maybe Check Point should consider to either have the certs be valid for three years, enable recertification options or release new exam versions more often. As far as I know all CCSM certs got extended for half a year since the R80 release was delayed..?
