2V0-21.23 Question 4
Select 3A company is designing its VMware vCenter architecture for a data center with high availability and scalability requirements. They plan to use Enhanced Linked Mode (ELM) to manage multiple vCenter Server instances. Which of the following components and configurations must be considered to successfully implement this architecture?
- A
All vCenter Server instances must be deployed in the same SSO domain.
- B
Each vCenter Server instance must have its own Platform Services Controller (PSC).
- C
Enhanced Linked Mode is only supported when vCenter Server is deployed as an appliance (VCSA).
- D
A single vSphere Client can be used to manage multiple vCenter Server instances in ELM.
- E
The vCenter Server instances in ELM can be deployed across different geographical locations.
Show answer and explanation
Correct answers: A, D, E
Explanation
Enhanced Linked Mode (ELM) is a critical feature of VMware vCenter Server architecture that allows multiple vCenter Server instances to be linked together for centralized management. To successfully set up ELM, all vCenter Server instances must belong to the same SSO domain, and a single vSphere Client can be used to manage the linked instances. ELM supports deployment across different geographical locations for distributed environments. However, external Platform Services Controllers (PSCs) are no longer used, as they have been replaced with embedded PSCs starting with vSphere 7.0.
- A. Correct.
Correct. For Enhanced Linked Mode to function, all vCenter Server instances must belong to the same Single Sign-On (SSO) domain.
- B. Incorrect.
Incorrect. Starting with vSphere 7.0, the Platform Services Controller (PSC) is embedded within vCenter Server, and external PSCs are deprecated.
- C. Incorrect.
Incorrect. Enhanced Linked Mode is supported on both vCenter Server Appliance (VCSA) and Windows-based vCenter Server (though the Windows version is deprecated as of vSphere 7.0).
- D. Correct.
Correct. Enhanced Linked Mode allows a single vSphere Client to manage all the linked vCenter Server instances.
- E. Correct.
Correct. vCenter Server instances in Enhanced Linked Mode can be deployed across different geographical locations, allowing for distributed management.
