Here are some links to older CCSA official study resources, all of which have many sample questions embedded in them (some of which were brought forward into later versions of the exam):
These cannot be found by navigating Check Point's website the usual way, but can still be accessed if you know these URLs. I figure if Check Point didn't want them to be available any more, they would delete them from the site entirely.
As far as third-party non-Pearson/VUE resources (especially ones that you pay for), they are all worthless and are selling dumps of questions for the R65 exam which was compromised long ago. The exams have been substantially redesigned and rewritten since then.
