2V0-21.23 Question 6
Select 3You are designing a VMware vSphere environment for a customer who requires centralized management of multiple ESXi hosts across different data centers. The customer also needs to ensure high availability for the management layer. Which components and topology would you recommend as part of the VMware vCenter architecture?
- A
Deploy vCenter Server as an embedded deployment model with the Platform Services Controller (PSC) and vCenter Server on the same node.
- B
Deploy vCenter Server in an external deployment model with the Platform Services Controller (PSC) on a separate node.
- C
Use the vCenter Enhanced Linked Mode to connect multiple vCenter Server instances for centralized management.
- D
Deploy a single, standalone vCenter Server instance with no redundancy.
- E
Configure a load balancer to distribute requests between Platform Services Controllers if using an external deployment.
Show answer and explanation
Correct answers: B, C, E
Explanation
For a VMware vSphere environment requiring centralized management and high availability, the recommended architecture involves using an external deployment model for vCenter Server with the Platform Services Controller on separate nodes. Enhanced Linked Mode is essential for connecting multiple vCenter Server instances, enabling centralized management. Additionally, configuring a load balancer for the Platform Services Controllers ensures redundancy and fault tolerance for critical management components.
- A. Incorrect.
An embedded deployment model is not recommended for environments requiring high availability and centralized management across multiple data centers. It is more suited for smaller setups.
- B. Correct.
Using an external deployment model with the PSC on a separate node provides flexibility and scalability, especially when combined with high availability configurations.
- C. Correct.
Enhanced Linked Mode allows centralized management of multiple vCenter Server instances, which is crucial for managing multiple ESXi hosts across different data centers as described in the scenario.
- D. Incorrect.
A single, standalone vCenter Server instance lacks redundancy and high availability, which the customer requires.
- E. Correct.
Configuring a load balancer for the Platform Services Controllers ensures high availability when using an external deployment model, meeting the customer's need for a resilient architecture.
