NSE 7 – SD-WAN 6.4 — Question 32

What are two reasons why it is effective to implement the internet service database (ISDB) in an SD-WAN rule? (Choose two.)

Answer options

• A. The ISDB is dynamically updated and reduces administrative overhead.
• B. The ISDB applies rules to traffic from specific sources, based on application type.
• C. The ISDB requires application control to maintain signatures and perform load-balancing.
• D. The ISDB contains the IP addresses and port ranges of well-known destinations.

Correct answer: A, D

Explanation

Option A is correct because the ISDB's dynamic updates alleviate the need for constant manual management. Option D is also correct as it provides essential information about common destination IPs and ports, aiding in efficient routing. Options B and C are incorrect because they either misrepresent the ISDB's function or introduce unnecessary requirements that are not inherent to its purpose.
