2V0-21.23 Question 5
Select 2An organization is planning to deploy a VMware vCenter Server environment to manage their virtual infrastructure. The design requires high availability and scalability to manage a large number of ESXi hosts and virtual machines. Which components and topology would best support this setup?
- A
Deploy an embedded vCenter Server with an embedded Platform Services Controller (PSC).
- B
Deploy an external vCenter Server with an external Platform Services Controller (PSC).
- C
Use Enhanced Linked Mode (ELM) to connect multiple vCenter Servers.
- D
Configure vCenter Server in a High Availability (HA) cluster mode.
- E
Install multiple Platform Services Controllers (PSCs) in a load-balanced setup.
Show answer and explanation
Correct answers: C, D
Explanation
In a large-scale environment with high availability and scalability requirements, Enhanced Linked Mode (ELM) is used to connect multiple vCenter Servers, allowing centralized management of the infrastructure. Additionally, vCenter Server High Availability (HA) ensures redundancy and continuity of operations in case of failure. These components and configurations align with VMware's recommended practices for such deployments.
- A. Incorrect.
An embedded vCenter Server with an embedded PSC is suitable for smaller environments. It does not provide the scalability or high availability required for large infrastructures.
- B. Incorrect.
The external PSC topology is deprecated in current VMware versions. VMware recommends using embedded PSCs for simplicity and support in modern vCenter deployments.
- C. Correct.
Enhanced Linked Mode (ELM) allows multiple vCenter Servers to be connected and managed from a single interface. This is essential for scalability in large environments.
- D. Correct.
Configuring vCenter Server in High Availability (HA) mode provides redundancy and ensures availability in case of a vCenter Server failure. This is critical for high availability requirements.
- E. Incorrect.
While PSCs could be deployed in a load-balanced setup historically, this design is no longer recommended as external PSCs are deprecated in modern versions of VMware vCenter.
