   A storage administrator is investigating a performance issue in a Metro Node environment. The administrator suspects that management operations are consuming resources that should be used for I/O. Which architectural feature of Metro Node prevents management operations from impacting I/O performance?

   • AThe use of a separate management controller, which handles all management operations.
   • BThe separation of the data path and control path, where management operations use the control path and I/O uses the data path.
   • CThe use of a dedicated management network, which isolates management traffic from I/O traffic.
   • DThe use of quality of service (QoS) to prioritize I/O over management traffic.

   What is the purpose of redundant power supplies in a Metro Node director?

   • ATo reduce the overall power consumption
   • BTo provide power redundancy in case one supply fails
   • CTo increase the processing speed of the director
   • DTo provide backup power for the entire data center

   A hospital is deploying Dell Metro Node to provide continuous availability for its electronic health record (EHR) application. The storage team wants to ensure that if one director in a Metro Node cluster fails, the other director can continue serving I/O without any host-visible disruption. Which architectural feature of Metro Node directly provides this capability?

   • AThe management controller automatically reboots a failed director and restores its I/O within seconds.
   • BThe data path is replicated to a remote Metro Node cluster, and the remote cluster takes over if the local director fails.
   • CA single director with redundant power supplies and fans ensures that a component failure does not interrupt I/O.
   • DTwo directors in each director group operate in an active/active configuration, and the surviving director takes over the failed director's I/O.

   A company is using Metro Node to virtualize storage from two different storage arrays. The storage team wants to present a single large virtual volume to a host, but the volume will span both arrays. Which Metro Node capability enables this?

   • AStorage virtualization, which pools back-end storage and presents virtual volumes to hosts.
   • BScalability, which allows adding more directors to support larger volumes.
   • CData mobility, which allows moving volumes between arrays.
   • DHigh availability, which ensures the volume remains accessible if one array fails.
