One of the major features in R81 SmartConsole is concurrent administration. This feature allows multiple administrators to work on the same Security Policy simultaneously, without blocking each other or creating conflicts. Concurrent administration improves the efficiency and productivity of security management operations1.

However, not all of the options given are possible considering that AdminA, AdminB and AdminC are editing the same Security Policy. The correct answer is B. AdminA and AdminB are editing the same rule at the same time. This is not possible because concurrent administration uses a locking mechanism to prevent multiple administrators from modifying the same rule or object at the same time. When an administrator clicks on a rule or an object, it becomes locked and a lock icon appears next to it. The lock icon shows the name of the administrator who is working on that rule or object, and prevents other administrators from editing it until it is unlocked12.

Therefore, the other options are possible considering that AdminA, AdminB and AdminC are editing the same Security Policy. Option A is possible because a lock icon shows that a rule or an object is locked and will be available when the administrator who locked it finishes working on it or logs out of SmartConsole12. Option C is possible because a lock icon next to a rule informs that any administrator is working on this particular rule, and hovering over the lock icon will show the name of that administrator12. Option D is possible because AdminA, AdminB and AdminC are editing three different rules at the same time, which does not create any conflicts or blockages12.
