What is the vSAN automatic rebalancing threshold recommended by VMware?
The recommended vSAN automatic rebalancing threshold by VMware is 20%. This threshold ensures that vSAN automatically initiates rebalancing operations when the storage utilization across the disks in the vSAN datastore becomes uneven beyond this threshold, maintaining optimal performance and storage efficiency.
In the vSphere Client, where is VxRail Health Monitoring enabled?
In the vSphere Client, VxRail Health Monitoring is enabled under Cluster > Configure > VxRail. This section provides an interface for configuring and monitoring VxRail-specific health and performance metrics, ensuring that administrators can effectively manage and monitor their VxRail clusters.
Steps:
Open the vSphere Client.
Navigate to the specific cluster.
Go to the Configure tab.
Select VxRail from the list.
By default, how often does the vSAN Skyline Health check run?
By default, the vSAN Skyline Health check runs every 60 minutes. This regular interval ensures that the health status of the vSAN environment is frequently assessed, allowing administrators to promptly address any issues that may arise.

What are two failure states of vSAN components? (Select 2)
The two failure states of vSAN components are 'Degraded' and 'Absent.'
Degraded: A vSAN component is considered degraded when it is still accessible but has experienced a loss of redundancy or other performance issues. This state indicates that the data is still available but may be at risk if further failures occur.
Absent: A vSAN component is in an absent state when it is temporarily unavailable, often due to transient issues like network disconnections or host reboots. The system expects the component to return shortly.
What are two considerations of deploying VxRail Cluster with an existing customer-supplied vCenter Server? (Select 2)
When deploying a VxRail Cluster with an existing customer-supplied vCenter Server, two key considerations are:
Supports Enhanced Link Mode with other VxRail-managed vCenter Servers: This allows the existing vCenter Server to link with other VxRail-managed vCenter Servers, providing a unified management interface across multiple vCenter instances, enabling seamless operations and better scalability.
Uses customer-defined procedures for vCenter LCM (Lifecycle Management): Since the vCenter Server is customer-supplied, the procedures for upgrading and maintaining it are defined and managed by the customer, rather than being automatically handled by VxRail's built-in lifecycle management tools.
