The correct answer is B. A core administrator-account best practice is to limit the use of Super User accounts. Super User has full read/write permissions, including sensitive capabilities such as managing administrators and sessions. Assigning this profile broadly violates least privilege and increases operational and security risk. Option A is wrong because unlimited concurrent administrative sessions can increase collision risk, accountability problems, and accidental overwrites. Option C is obviously insecure; administrator accounts require strong authentication controls. Option D is the opposite of best practice: roles should be based on least privilege, not maximum privilege. In Check Point R82, permission profiles such as Read Only All, Read Write All, and Super User allow administrators to assign access according to job function. Custom profiles may also be used where more granular control is needed. Reference topics: Administrator Account Management, permission profiles, Super User, least privilege.
