An event subscription must survive a regional outage of the handler. Which configuration helps most?
- A Shorter TTL
- B Dead-lettering to a geo-redundant storage account plus a replay process (correct answer)
- C Disabling retries
- D Batched delivery
Shortcut: Undeliverable events land in the dead-letter container. Storing that in GRS and building a replay mechanism means no event is lost during an extended handler outage.
