Explanation/Reference:
The EMC VPLEX family is the next-generation solution for data mobility and access within, across and between data centers.
VPLEX supports two configurations, local and metro. In the case of VPLEX Metro with the optional VPLEX Witness and Cross-Connected configuration, applications continue to operate in the surviving site with no interruption or downtime. Storage resources virtualized by VPLEX cooperate through the stack, with the ability to dynamically move applications and data across geographies and service providers.
Incorrect Answers:
A: EMC ViPR Controller is a software-defined storage platform that abstracts, pools and automates a data center's underlying physical storage infrastructure. It provides data center administrators with a single control plane for heterogeneous storage systems.
B: The EMC RecoverPoint family provides cost-effective, local continuous data protection (CDP), continuous remote replication (CRR), and continuous local and remote replication (CLR) that allows for any-point-in-time data recovery and a new "snap and replicate" mechanism for local and remote replication (XRP). This enables replication for high-performance, low-latency applications.
D: EMC ViPR SRM provides comprehensive monitoring, reporting and analysis for heterogeneous block, file and virtualized storage environments. It enables the users to visualize applications to storage dependencies, monitor and analyze configurations and capacity growth, and optimize their environment to improve return on investment.
