What is the best practice for installing the security policy?

The correct answer is C. The best practice is to use the Install Policy button in the active policy inside the Security Policies view. This keeps the administrator’s workflow tied directly to the policy package and installation targets being managed. Option A is less precise because the global toolbar may not make the selected policy context as clear. Option B is valid for automation, but it is not the best-practice SmartConsole workflow being tested in a CCSA administrator question. Option D is not the recommended normal installation workflow. The important sequence is: make policy changes in a SmartConsole session, publish the session, verify policy package/installation targets, then install policy to the correct gateways or clusters. Installing the wrong package or target is a common operational error, so using the active policy context reduces ambiguity.
