What is the purpose of storage protocol end-to-end routing?

• A. DNS resolution for clients during failover.
• B. Ensures correct path selection, failover, and access for clients across LIFs and networks.
• C. Enforces LUN size limits across volumes.
• D. Configures RAID levels for performance.

Answer: (B)

End-to-end routing for a storage protocol is about making sure the data path from the client to the storage array is correctly established and maintained across the entire network fabric. It coordinates how traffic travels from the host through the network to the right storage LIFs, selects the best available path, and automatically fails over to alternate paths when a link or LIF becomes unavailable. This keeps access to storage reliable and performant even as networks change or components fail.

Why this is the best fit: it directly describes managing how storage protocol traffic is routed end-to-end, including path selection, failover, and access across multiple LIFs and networks. The other options don’t pertain to routing of storage protocol traffic: DNS resolution relates to name lookup, not path routing; enforcing LUN size limits concerns capacity, not path decisions; configuring RAID levels relates to data layout and redundancy on disks, not host-to-storage routing.
