How can the same production data be protected against system outage with a zero RPO and a maximum of 15 minutes RPO data recovery?

A company has a Dell Unity XT 880 at its Boston site providing file storage for a business production application. The company has a second remote site 8 km (5 mi) away in Cambridge A third site is in New York (342 km (213 mi) from the Boston site)

Answer: B

Explanation:

Synchronous replication will provide a zero RPO as all data is written to both the primary and secondary storage at the same time, which means any data written to the primary storage will be instantly available on the secondary storage. This configuration will ensure that the data is protected against system outage, and in case of any failure, the recovery time will be a maximum of 15 minutes as the data is already replicated to the secondary site.
