During the PowerFlex implementation process, the following networks are typically configured to ensure proper communication and functionality of the system:

flex-node-mgmt (Option A):

This network handles the management traffic for PowerFlex nodes.

It ensures communication between the nodes and the management interfaces.

pfmc-sdc-mgmt (Option B):

This network is responsible for managing the communication between the Storage Data Client (SDC) and other PowerFlex components.

It ensures proper data access and retrieval from the storage layer.

flex-node-data (Option E):

The data network facilitates data transfer and communication between nodes in the PowerFlex cluster.

This network is critical for high-speed data access and ensuring efficient storage operations.

Why Not the Other Options?

Option C: pfmc-sds-mgmt: While this may sound plausible, it is not a standard network configured during the implementation process.

Option D: pfmc-vmotion: vMotion is a VMware-specific feature for live migration of VMs and is not a primary PowerFlex network configuration.
