   A company has a primary PowerMax in Seattle. They need to replicate to a DR site in Portland with synchronous replication and to a reporting site in Spokane with asynchronous replication. The Portland and Spokane arrays are both directly connected to the Seattle array. The architect is considering whether to use concurrent SRDF or two separate SRDF sessions. What is the key advantage of concurrent SRDF over two separate sessions?

   • AConcurrent SRDF eliminates the need for a DR site
   • BConcurrent SRDF allows a single source to maintain both sessions with different RPOs without requiring a separate SRDF group
   • CConcurrent SRDF allows the targets to replicate to each other
   • DConcurrent SRDF reduces the distance between the source and the targets

   What is the main purpose of a multi-hop SRDF topology?

   • ATo reduce the number of arrays required
   • BTo replicate to multiple targets simultaneously
   • CTo provide a single local copy for fast recovery
   • DTo extend replication over longer distances

   A media company has a production PowerMax in Los Angeles. They need to replicate to a DR site in San Francisco with synchronous replication and to a backup site in San Diego with asynchronous replication. Both target arrays are directly connected to the source. What is the primary advantage of using concurrent SRDF in this scenario?

   • AIt allows the source to maintain two independent replication sessions with different RPOs
   • BIt eliminates the need for a separate DR site
   • CIt allows the targets to replicate to each other
   • DIt reduces the distance between the source and the targets

   An organization has a primary PowerMax in Dallas. They need to replicate to a DR site in Houston with a synchronous copy for zero data loss. They also need a second copy in Austin for reporting, but the Austin site can tolerate up to 5 minutes of data loss. The Houston and Austin arrays are both directly connected to the Dallas array. What is the most appropriate topology?

   • AMulti-hop SRDF with an intermediate array between Dallas and Austin
   • BCascaded SRDF with Houston as the intermediate and Austin as the final target
   • CConcurrent SRDF with SRDF/S to Houston and SRDF/A to Austin
   • DTwo separate SRDF/S sessions to both Houston and Austin

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

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