   A university is deploying Metro Node to consolidate storage from multiple vendors into a single pool. The IT team wants to move a virtual volume from one back-end array to another without disrupting running applications. Which Metro Node capability directly supports this requirement?

   • AVirtualization, which presents the back-end arrays as a single pool to hosts.
   • BHigh availability, which ensures that the virtual volume remains accessible if one array fails.
   • CData mobility, which allows online migration of virtual volumes between back-end storage arrays.
   • DScalability, which allows adding more directors to handle the increased I/O during migration.

   A company is designing a Metro Node deployment to virtualize storage for a mission-critical application. The application requires low latency, and the storage team is concerned about the impact of the data path on performance. The team is considering whether to place the Metro Node directors in the data path or use a different architecture. What is the correct approach?

   • AUse the control path for host I/O to reduce latency, since the control path is optimized for performance.
   • BPlace the directors in the data path, as Metro Node is designed to be an inline appliance that virtualizes storage.
   • CPlace the directors out of the data path and use a management network to control the storage arrays.
   • DUse a separate data path for each storage array, bypassing the directors for direct host access.

   A company is deciding between a local and a metro configuration for Metro Node. The company has a single data center and wants to ensure high availability for its storage. The storage team is concerned about the complexity of a metro configuration. What is the most appropriate deployment model for this company?

   • AA configuration with a single director, which is simpler and sufficient for high availability.
   • BLocal configuration, which provides high availability within a single data center using redundant directors.
   • CA configuration that uses the storage array's built-in replication instead of Metro Node.
   • DMetro configuration, which provides high availability across two data centers.
