Why this is correct (based on the screenshot)

The image shows a Virtual Server Load Balancing configuration with:

Default Persistence Profile: cookie

Fallback Persistence Profile: None

When an application requires a Fallback Persistence Profile, BIG-IP supports only one persistence type for fallback use:

👉 Universal Persistence

Universal persistence is designed specifically to act as a fallback when the primary persistence method (such as cookies) is unavailable.

Source Address Affinity works every time, regardless of:
• HTTP vs HTTPS
• Missing cookies
• Broken headers
• API vs browser
• Mobile vs desktop
• Encrypted payloads
It’s the only persistence method that is universally safe as fallback.

Exactly, Thanks

D. Source Address Affinity
When the default persistence profile is cookie, the appropriate fallback persistence profile is Source Address Affinity. Cookie persistence only works when a client supports cookies; if a client doesn't support cookies, the fallback kicks in — and Source Address Affinity (which tracks clients by IP address) is the standard fallback choice for cookie-based persistence.
