Question
What are two benefits of using the Internet service database (ISDB) in an SD-WAN rule? (Choose two.)
A. The ISDB is dynamically updated and reduces administrative overhead.
B. The ISDB requires application control to maintain signatures and perform load balancing.
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.
Answer
A. The ISDB is dynamically updated and reduces administrative overhead.
D. The ISDB contains the IP addresses and port ranges of well-known internet services.
Explanation
The Internet Service Database (ISDB) offers two significant benefits when used in SD-WAN rules:
- Dynamic Updates and Reduced Overhead (A): The ISDB is continuously updated by the vendor, ensuring that the latest IP addresses and port ranges of well-known internet services are always available. This dynamic update process eliminates the need for manual maintenance, reducing administrative overhead for the network administrators.
- Contains IP Addresses and Port Ranges (D): The ISDB is a comprehensive database that contains the IP addresses and port ranges of well-known internet services. By leveraging this information, SD-WAN rules can accurately identify and manage traffic based on the specific internet service being accessed, without the need for manual configuration of IP addresses and port ranges.
Incorrect options:
B is incorrect because the ISDB does not require application control to maintain signatures or perform load balancing. Application control is a separate feature that works in conjunction with the ISDB.
C is incorrect because the ISDB does not apply rules based on specific sources or application types. It focuses on the IP addresses and port ranges of internet services.
