The suggested answer is B.
The current private cloud setup has 30 vCPUs and 512GB of RAM available. For the expected maximum sessions of close to 24,000, the application requires 8 nodes with 8 vCPUs and 128GB of RAM each. This amounts to a total requirement of 64 vCPUs and 1024GB of RAM, which the private cloud cannot support on its own. However, the average sessions are approximately 5,000, which requires 4 nodes with 6 vCPUs and 64GB of RAM each, amounting to 24 vCPUs and 256GB of RAM, which is within the current capacity. Setting up cloud bursting allows the private cloud to handle the average load while leveraging additional public cloud resources to manage peak loads, thus providing a quick and financially beneficial solution.
