You are asked to size a cluster for a file sharing environment. nfsstat indicates that no more than 10% of the requests are namespace operations (e.g. GETADDR, SETADDR). There will be 10,000 active Linux users, connecting over NFS. Which cluster configuration would you recommend?

The correct answer is A because it provides the highest capacity and redundancy for the given requirements. The 10% namespace operations indicate that a large number of metadata operations are not required, so the SSDs are not necessary. The N+2:1 redundancy provides high availability and fault tolerance.
