Explanation
Active/active architecture (B) is correct because Prisma SD-WAN achieves high availability by running both network paths simultaneously - traffic is distributed across multiple links at the same time, eliminating single points of failure and removing the failover delay inherent in standby-based designs.
Why the distractors are wrong:
- A. SSL Forward Proxy - a security inspection feature that decrypts/re-encrypts SSL traffic; it has nothing to do with network path redundancy or uptime.
- C. Secure Web Gateway - a security service for filtering and controlling web traffic; it addresses threat protection, not HA.
- D. Dual VPN tunnels - while dual tunnels do add redundancy, they typically imply an active/standby model where one tunnel is idle until failover. Active/active is the broader architectural principle that uses such redundancy simultaneously, making B the more precise and correct answer.
Memory tip: Think "Active/Active = Always Available." The two A's in active/active mirror the two A's in high AvAilability - both paths are live, so there's no wait for a backup to kick in.
