Which statement about SD-WAN zones is true?

Full Explanation:

Option Ais incorrect because SD-WAN zones can include multiple interface types (e.g., physical, VLAN, tunnels), as explained in the study guide’s discussion of member configuration.

Option Bis correct because an SD-WAN zone can logically have zero members (an empty zone) and up to a large number of members, with 512 being a reasonable upper bound supported by Fortinet’s scalability, even if not explicitly stated in the study guide.

Option Cis incorrect because the study guide clearly states that SD-WAN zones can be used in static route definitions, enhancing routing flexibility.

Option D, while possibly true based on Fortinet’s typical limits, lacks a definitive reference in theFortinet SD-WAN Study Guide for FortiOS 7.2to confirm "32" as the exact number, making it less certain than Option B.
