   A global enterprise has a primary data center in Sydney and a DR site in Los Angeles. The distance is over 12,000 km, and the direct link has high latency. The architect plans to place intermediate PowerMax arrays in Singapore and Honolulu to relay data and improve performance. Which SRDF topology should be used, and what is the primary benefit?

   • AMulti-target SRDF, which allows replication to multiple targets for different purposes
   • BConcurrent SRDF, which allows the source to replicate to multiple targets simultaneously
   • CCascaded SRDF, which provides the lowest possible RPO
   • DMulti-hop SRDF, which reduces the effective distance of each hop and improves performance

   A company has a primary PowerMax in Paris and a DR site in Lyon. They want to add a third site in Marseille for additional protection. The Paris-to-Lyon link is synchronous, and the Lyon-to-Marseille link is asynchronous. The company is considering whether to use a cascaded topology or a concurrent topology with a direct link from Paris to Marseille. The direct link from Paris to Marseille is available but has higher latency than the Paris-to-Lyon link. What is the primary trade-off the architect must consider?

   • AConcurrent topology provides a lower RPO for Marseille but requires a high-bandwidth direct link from Paris
   • BCascaded topology reduces the need for a high-bandwidth direct link to Marseille but adds latency to the Marseille copy
   • CCascaded topology provides a lower RPO for Marseille but requires a high-bandwidth direct link from Paris
   • DConcurrent topology reduces the need for a high-bandwidth direct link to Marseille but adds latency to the Marseille copy

   What is a key characteristic of cascaded SRDF compared to concurrent SRDF?

   • AData flows through an intermediate array
   • BIt uses only synchronous replication
   • CIt replicates to multiple targets simultaneously
   • DIt requires a third-party replication software
