   What is a key characteristic of asynchronous remote replication?

   • AIt acknowledges writes at the primary site before sending data to the secondary site
   • BIt ensures zero data loss in the event of a failure
   • CIt requires the secondary site to acknowledge every write before the primary can proceed
   • DIt is only suitable for short-distance replication

   A media company replicates large video files to a remote site over a WAN link with limited bandwidth. The RPO is 15 minutes, and the link is often congested. The administrator needs to minimize bandwidth usage while still meeting the RPO. Which replication method should be used?

   • ASemi-synchronous replication
   • BSynchronous replication
   • CAsynchronous replication
   • DContinuous data protection (CDP)

   How does synchronous remote replication ensure consistency between the primary and secondary sites?

   • AIt writes data to a cache at the primary site and flushes it later
   • BIt acknowledges a write only after the data is committed at both the primary and secondary sites
   • CIt uses a journal to replay writes at the secondary site after a failure
   • DIt batches writes and sends them periodically to the secondary site

   A company has a primary site in New York, a DR site in Chicago, and a backup site in Denver. The company wants to replicate data from New York to Chicago, and also from New York to Denver. However, the bandwidth between New York and Denver is limited. To reduce bandwidth usage, the administrator decides to replicate from New York to Chicago, and then from Chicago to Denver. What is the benefit of this multi-hop topology?

   • AIt reduces the bandwidth required on the New York-to-Denver link
   • BIt eliminates the need for a DR site in Chicago
   • CIt provides a lower RPO than point-to-point replication
   • DIt simplifies the replication configuration
