2V0-21.23 Question 305
Single answerAn organization is running a vSphere environment with multiple departments sharing the same cluster. The IT administrator wants to ensure that each department receives a specific amount of CPU and memory resources, and any unused resources can be distributed among other departments. Which use case for resource pools aligns with this requirement?
- A
Isolate workloads to prevent resource contention between departments.
- B
Allocate resources dynamically based on workload priority.
- C
Provide guaranteed minimum and maximum resource limits for departments.
- D
Enable resource overcommitment for all virtual machines in the cluster.
Show answer and explanation
Correct answer: C
Explanation
Resource pools in vSphere are designed to help administrators allocate and manage resources effectively within a shared infrastructure. In this scenario, the goal is to provide each department with a guaranteed minimum resource allocation (reservations) and prevent overallocation (limits), while allowing unused resources to be dynamically shared. This aligns with the use case of setting guaranteed minimum and maximum resource limits for departments.
- A. Incorrect.
While resource pools can help isolate workloads, this option does not address the need to allocate specific resource amounts to each department or allow resource sharing when unused.
- B. Incorrect.
Dynamic allocation of resources is not the primary use case for this scenario. The requirement is to set specific guaranteed resource limits for departments, not just prioritize workloads.
- C. Correct.
This option is correct because resource pools can be used to set specific resource allocations (reservations, limits, and shares) for each department. It ensures that minimum resources are guaranteed while enabling unused resources to be shared among departments.
- D. Incorrect.
Resource overcommitment is not directly related to the use of resource pools for managing departmental resource allocations. Overcommitment focuses on exceeding physical resource capacities, which is not the goal here.
