Question
An environment has two VxRail clusters with separate vCenters. Logging in to either vCenter, there is only one cluster visible. What deployment method was used in this scenario?
A. each uses an internal vCenter with Enhanced Link Mode
B. each uses an internal vCenter without Enhanced Link Mode
C. both share a single vSphere standard switch object
D. both share a single vSphere distributed switch object
Answer
B. each uses an internal vCenter without Enhanced Link Mode
Explanation
The correct answer is B. Each uses an internal vCenter without Enhanced Link Mode.
In this scenario, each VxRail cluster has its own vCenter, and when logging into either vCenter, only one cluster is visible. This indicates that each vCenter is managing its own VxRail cluster independently, and there is no link between the two vCenters. This is characteristic of a deployment where each VxRail cluster uses an internal vCenter without Enhanced Link Mode.
Here’s a more detailed explanation:
In a VMware vSphere environment, vCenter Server is the central management component. It manages resources like hosts (ESXi servers), virtual machines, storage, and networking. In a VxRail environment, vCenter can be deployed internally (on the VxRail cluster itself) or externally (on a separate system).
Enhanced Link Mode is a feature that allows multiple vCenter Servers to be linked together to form a single vSphere domain. This allows administrators to log in to any linked vCenter Server and view and manage the inventories of all the linked vCenter Servers. If Enhanced Link Mode was enabled in this scenario, logging in to either vCenter would show both VxRail clusters.
However, in this scenario, logging in to either vCenter only shows one cluster. This indicates that Enhanced Link Mode is not enabled, and each vCenter is managing its own VxRail cluster independently. Therefore, the deployment method used in this scenario is that each VxRail cluster uses an internal vCenter without Enhanced Link Mode.
The other options (each uses an internal vCenter with Enhanced Link Mode, both share a single vSphere standard switch object, both share a single vSphere distributed switch object) are not correct based on the information provided in the scenario.
Option A (each uses an internal vCenter with Enhanced Link Mode) would result in both clusters being visible when logging in to either vCenter, which is not the case in this scenario.
Options C and D (both share a single vSphere standard switch object, both share a single vSphere distributed switch object) are related to networking configuration, not vCenter deployment or visibility of clusters in vCenter. A vSphere standard switch or distributed switch is a virtual switch that provides connectivity for virtual machines and hosts. Sharing a single switch object would not affect the visibility of clusters in vCenter.
