Which VxRail networks support link aggregation1?
In VxRail networks, the vSAN and vMotion networks support link aggregation. Link aggregation (also known as NIC teaming) allows multiple network interfaces to be combined into a single logical interface, providing redundancy and increased throughput. This is particularly beneficial for vSAN traffic, which requires high bandwidth and low latency, and vMotion traffic, which benefits from increased network performance during virtual machine migrations.

VxRail nodes have been purchased to add additional capacity The new nodes are based on AMD Chipset, the current cluster is based on Intel Chipset
What should be the next step?
When adding VxRail nodes based on a different chipset (e.g., AMD vs. Intel) to an existing cluster, it is necessary to enable VMware Enhanced vMotion Compatibility (EVC) mode. EVC ensures CPU compatibility for vMotion by masking certain CPU features, making it possible to add nodes with different processors to the same cluster without causing compatibility issues.
Steps:
Enable VMware EVC mode on the existing cluster.
Ensure all cluster nodes meet the EVC requirements.
Add the new AMD-based nodes to the existing cluster.
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.

An environment has two VxRail Clusters with the following configuration
* Cluster-A is using FTT = 2 and FTM = Erasure Coding
* Cluster-B is using FTT = 2 and FTM = Mirroring
A 100 GB VM is planned to be vMotioned from Cluster-A to Cluster-B. How much more vSAN capacity is consumed in Cluster-B than in Cluster-A?
To calculate the additional vSAN capacity consumed when a 100 GB VM is vMotioned from Cluster-A to Cluster-B, consider the following:
Cluster-A: FTT = 2 and FTM = Erasure Coding (RAID 6), which uses approximately 1.5 times the data size, thus 100 GB VM uses about 150 GB of vSAN capacity.
Cluster-B: FTT = 2 and FTM = Mirroring (RAID 1), which uses 3 times the data size, thus 100 GB VM uses 300 GB of vSAN capacity.
The difference in vSAN capacity consumed between Cluster-B and Cluster-A is: 300 GB (Cluster-B) - 150 GB (Cluster-A) = 150 GB
So, Cluster-B consumes 150 GB more vSAN capacity than Cluster-A.
