CC5 Control Activities contains 3 criteria. The Trust Services Criteria define 61 in total: 33 Common Criteria across CC1–CC9 plus the criteria for the Availability, Confidentiality, Processing Integrity and Privacy categories.
Yes. CC5 is part of the Common Criteria, which apply to every SOC 2 engagement regardless of which additional categories you scope in.
