A production-grade cloud, as required for 5G/NFV, must distribute compute, storage and control functions over several physical hosts to provide elasticity and fault-tolerance. Nokia CloudBand Infrastructure Software—the reference platform used in BL0-220—specifies a minimum three-node topology; a single-server build is permitted only for lab/PoC exercises and is explicitly “not considered a cloud deployment.” ETSI NFV reliability guidelines likewise mandate node redundancy. Therefore a genuine cloud solution cannot be run on just one node, making the statement false.

A True — Single-node installations lack redundancy and are not supported for production cloud operation; only multi-node topologies qualify under Nokia and ETSI specifications.
