Answer options

• A. The ISDB is dynamically updated and reduces administrative overhead.

• C. The ISDB applies rules to traffic from specific sources, based on application type.
• D. The ISDB contains the IP addresses and port ranges of well-known internet services.

Correct answer: A, D

Explanation

Option A is correct because the ISDB's dynamic updates help minimize the need for manual management, thereby lowering administrative tasks.
