50. A data center has 12 compute resource units, 20 storage resource units, and 10 network resource units available in its resource pools. An application requires 4 compute units, 6 storage units, and 2 network units. Assuming all resources are compatible and no additional constraints apply, how many identical application configurations can be provisioned simultaneously?

  1. Two configurations
  2. Three configurations
  3. Four configurations
  4. Five configurations

Answer: B) Three configurations

Explanation:

Compute resources support 12 / 4 = 3 configurations. Storage resources support 20 / 6 = 3 complete configurations, with 2 storage units remaining. Network resources support 10 / 2 = 5 configurations. The maximum number of complete configurations is the minimum of these values: min(3, 3, 5) = 3. Therefore, three identical application configurations can be provisioned simultaneously.
