   A two-node ONTAP cluster is being deployed to serve NFS and SMB data. The customer wants to ensure that if one controller fails, the other can continue serving data with minimal disruption. Which configuration best meets this requirement?

   • AEnable Storage Failover (SFO) and configure the data LIFs to fail over to the surviving node.
   • BUse a single active/passive cluster with the passive node only for management functions.
   • CPlace all data on the first node and use the second node only for backup via SnapMirror.
   • DConfigure the cluster with a single management LIF and use DNS round-robin for client access.

   A customer is planning to deploy an ONTAP cluster for a high-performance computing (HPC) workload that requires very low latency. They are considering using NVMe over Fabrics (NVMe-oF). Which controller hardware component is most critical to support this?

   • ALarge amounts of NVRAM for write caching
   • BMultiple SAS adapters for storage connectivity
   • CHigh-speed network adapters (e.g., 25/100GbE) with RDMA support
   • DA high-core-count CPU for processing

   A company is deploying an ONTAP cluster with four nodes. They want to ensure that if one node fails, the remaining nodes can still serve all data. Which configuration is required?

   • AThe cluster must be configured with a single SFO domain for all nodes.
   • BAll nodes must be connected to the same storage shelves.
   • CThe cluster must have a dedicated management node.
   • DEach node must have enough capacity to absorb the storage of a failed node.
