ASix Functions
BFive Functions
CSeven Functions
DFour Functions
Answer & Solution
Correct answer: A. Six Functions
1. Section 2 names the Functions in one line: "The CSF Core Functions -- GOVERN, IDENTIFY, PROTECT, DETECT, RESPOND, and RECOVER -- organize cybersecurity outcomes at their highest level."
2. Counting that list gives six.
3. Five is the trap answer because CSF 1.1 had five Functions; GOVERN was added in version 2.0 and is the sixth.
4. A useful cross-check: section 2 also says GOVERN "provides outcomes to inform what an organization may do to achieve and prioritize the outcomes of the other five Functions", which only reads correctly if the total is six.
