Within SmartConsole, administrators work in sessions.

The correct answer is A. In SmartConsole, a session is a working environment where administrators can make changes without immediately committing them to the published management database or affecting the live enforcement state. Changes remain in the administrator’s session until they are published or discarded. Publishing commits changes and creates a revision; installing policy then pushes the published policy to selected gateways. Option B is wrong because sessions are not only for managers, and ordinary administrators work inside sessions depending on their permissions. Option C is the opposite of the real model; sessions specifically prevent every edit from immediately affecting the published configuration. Option D is wrong because sessions are not read-only by default; permissions determine whether the administrator can make changes. This session model is critical in multi-administrator environments because it supports change isolation, review, accountability, publishing, revision comparison, and controlled installation.
