[All NCP-MCI Questions]

An administrator needs to deploy an application with a large amount of data connected via Nutanix volumes.

Which two actions should the administrator take when designing the Volume Group? (Choose two.)

ADistribute workload across multiple virtual disks

BEnable RSS (Receive Side Scaling)

CUse multiple subnets for iSCSI traffic

DEnable thick provisioning on the Volume Group(s)

Show Suggested Answer

Suggested Answer: A, B

According to the Nutanix Volumes - Recommendations And Best Practices web search result3, two actions that the administrator should take when designing the Volume Group are:

Distribute workload across multiple virtual disks: Use multiple disks rather than a single large disk for an application. Consider using a minimum of one disk per Nutanix node to distribute the workload across all nodes in a cluster. Multiple disks per Nutanix node may also improve an application's performance. For performance-intensive environments, we recommend using between four and eight disks per CVM for a given workload.

Enable RSS (Receive Side Scaling): Receive-side scaling (RSS) allows the system to use multiple CPUs for network activity. With RSS enabled, multiple CPU cores process network traffic, preventing a single CPU core from becoming a bottleneck. Enabling RSS within hosts can be beneficial for heavy iSCSI workloads. For VMs running in ESXi environments, RSS requires VMXNET3 VNICs. For Hyper-V environments, enable VMQ to take full advantage of Virtual RSS.

Alright, let's summarize what we've got so far. I'd say the two best options are A (distribute workload across multiple virtual disks) and D (enable thick provisioning). C (use multiple subnets for iSCSI) is also worth considering, but B (enable RSS) doesn't seem as relevant. Sound good, team?

I'm not sure about B, enabling RSS may not be necessary for our specific setup.

I agree, this question is relevant. I'm leaning towards options A and D as the best answers. Distributing the workload across multiple virtual disks can help improve performance, and thick provisioning can ensure the volumes have the necessary space allocated.
