Which of the following types of the penetration tests is being done when the tester is supplied with extensive knowledge of the target network?

In a known environment (white-box) test, the tester is given extensive knowledge of the target network. Full disclosure is not a term used to describe testing. Unknown environment (black-box) testing involves only very minimal information being given to the tester. A red team test simulates a particular type of attackers, such as a nation-state attacker, an insider, or other types of attacker.
