   A company is adding a new storage data server to a PowerFlex cluster. The new server has 64GB RAM, two 10GbE NICs, and four 1.92TB SSDs. The administrator plans to use all four SSDs for capacity. The cluster currently has a mix of 10GbE and 25GbE storage networks. The administrator wants to ensure the new SDS performs optimally. Which prerequisite check is most important?

   • ACheck that the SSDs are connected to the storage network via the management NIC.
   • BVerify that the SSDs are raw and have no existing filesystem or partitioning.
   • CEnsure that the server has at least 128GB RAM to support four SSDs.
   • DConfirm that the 10GbE NICs are configured to use the same speed as the 25GbE network.

   A storage administrator has added a new SDS to a PowerFlex cluster and wants to create a new storage pool for a tier of SSDs. The SDS has 12 SSDs. The administrator wants to use 8 of them for the new pool and leave 4 as spares. Which step is required to accomplish this?

   • ACreate two storage pools: one with 8 devices and one with 4 devices.
   • BAdd all 12 devices to the new storage pool, then remove 4 devices from the pool to keep them as spares.
   • CCreate the storage pool, then add only the 8 devices to the pool, leaving the other 4 unassigned.
   • DFormat the 4 spare devices with a filesystem to prevent PowerFlex from using them.

   An administrator is adding a new storage data server to a PowerFlex cluster using the CLI. The new node has been prepared with the OS and network configuration. The administrator runs the 'add_sds' command, but it fails with a 'connection refused' error. The administrator can ping the new node's management IP from the MDM. What is the most likely cause?

   • AThe new node's storage NIC is not on the same subnet as the MDM.
   • BThe new node's storage devices are not formatted with a filesystem.
   • CThe PowerFlex agent service is not running on the new node.
   • DThe PowerFlex CLI version is incompatible with the cluster version.

   A company is expanding its PowerFlex cluster with a new storage data server. The new server has 64GB RAM, two 25GbE NICs, and six 3.84TB NVMe drives. The administrator plans to use all six NVMe drives for capacity. The cluster currently uses 10GbE networking for storage. The administrator wants to minimize the risk of performance bottlenecks. Which prerequisite check is most important before adding this SDS?

   • AEnsure that the NVMe drives are raw and have no existing filesystem or partitioning.
   • BVerify that the 25GbE NICs are configured to operate at the same speed as the existing 10GbE storage network.
   • CConfirm that the server has at least 128GB RAM to support NVMe drives.
   • DCheck that the 25GbE NICs are on the same VLAN as the management network.

   After adding a new SDS and configuring its devices in a storage pool, an administrator notices that the SDS is listed as 'Disconnected' in the PowerFlex GUI. What is the most likely cause?

   • AThe SDS's devices are not formatted with a filesystem.
   • BThe SDS's hostname is not resolvable via DNS.
   • CThe storage pool has reached its maximum capacity.
   • DThe SDS's storage NIC is down or has lost connectivity to the storage network.
