Explanation
In a multi-appliance cluster, the Master appliance serves as the central coordinator for cluster-wide operations, including receiving and distributing NDU (Non-Disruptive Upgrade) packages - making A correct. Option B is wrong because "primary node" refers to a node role within a single appliance's HA pair, not a cluster-level distribution function. Option C is wrong because not just any node on any appliance has the authority or role to orchestrate cluster-wide package distribution. Option D is wrong because a "peer node" is the secondary/standby node in an HA pair, which has no cluster management responsibilities.
Memory tip: Think of the Master appliance like a postal hub - all packages arrive there first, then get routed outward. "Master = receiver and distributor" in the cluster hierarchy.
