2V0-21.23 Question 23
Select 3A VMware administrator is tasked with configuring a vSphere environment to ensure that virtual machines (VMs) meet specific storage requirements, such as performance and availability levels. The administrator decides to use storage policies to achieve this. Which of the following statements about the use of storage policies in vSphere are correct?
- A
Storage policies allow administrators to define specific rules that govern placement and data services for VMs.
- B
Storage policies can only be applied during the initial provisioning of a virtual machine and cannot be edited later.
- C
VMware vSAN uses storage policies to define requirements like failures to tolerate (FTT) and stripe width.
- D
Storage policies are used exclusively for storage-based backups and do not impact VM placement.
- E
Storage policies can dynamically adjust VM storage placement when underlying storage changes to ensure compliance.
Show answer and explanation
Correct answers: A, C, E
Explanation
Storage policies in vSphere are a powerful tool that allow administrators to define and enforce specific storage requirements for virtual machines, such as performance, redundancy, and availability. These policies work dynamically to ensure compliance and can integrate with features like VMware vSAN to define parameters like failures to tolerate (FTT). They can be applied during provisioning or updated later, providing flexibility in managing storage requirements as infrastructure changes.
- A. Correct.
Correct: Storage policies allow administrators to define rules for VM placement and data services, ensuring VMs meet specific requirements for performance, redundancy, and availability.
- B. Incorrect.
Incorrect: Storage policies can be edited after VM provisioning to accommodate changes in requirements or infrastructure.
- C. Correct.
Correct: VMware vSAN integrates with storage policies to define parameters like failures to tolerate (FTT) and stripe width, ensuring the desired level of data protection and performance.
- D. Incorrect.
Incorrect: Storage policies are not limited to backups; they play a significant role in determining VM storage placement and compliance with defined rules.
- E. Correct.
Correct: Storage policies can ensure compliance dynamically by adjusting VM storage placement if the underlying storage infrastructure changes (e.g., disk failure or capacity constraints).
