Refer to the exhibit.
The customer has an existing NX-3160 block and is adding a second node into it.
Where should the node be installed?"
Based on the exhibit which shows an NX-3160 block with marked slots, the correct slot for installing a new node in the existing NX-3160 block is slot 2. This configuration is typically aligned with the chassis' design for orderly expansion and maintaining balanced power and cooling distribution among the nodes.

A consultant and customer agree on a scope of services regarding the deployment of a new Nutanix cluster.
Which two products does this scope apply to? (Choose two.)
The scope of services for the deployment of a new Nutanix cluster would apply to both Foundation and Prism Central. Foundation is the initial software used for deploying Nutanix nodes and creating clusters, essential for setting up the environment. Prism Central is used for managing multiple clusters and is integral to the operational scope of the service, providing centralized management capabilities. Reference: Nutanix Bible, Nutanix University NCS-Core 6.8 learning materials
A consultant deploys a Nutanix cluster with AOS and ESXi. The cluster is managed by a vCenter server.
After installation, what should the consultant do to ensure the cluster will support network segmentation?
After deploying a Nutanix cluster with AOS and ESXi managed by a vCenter server, the consultant should ensure that both CVM eth0 and eth2 interfaces are connected to the assigned portgroups on the standard or distributed switch. This setup allows for network segmentation and proper traffic isolation, which is crucial for maintaining network security and efficiency in a virtualized environment.

A consultant deploys a new ESXi-based Nutanix cluster and migrates a sphere deployment to the cluster, After completing the deployment, the customer states they are experiencing VM performance issues.
Upon observing logs and performance data, the consultant identified the following symptoms.
Excessive read/write 1/Os on CVMs
Excessive Motion of VMs
What is causing this issue?
The customer is experiencing VM performance issues characterized by excessive read/write I/Os on CVMs and excessive motion of VMs due to the Distributed Resource Scheduler (DRS) in an ESXi-based Nutanix cluster. This is likely caused by the DRS migration threshold being set to Aggressive, which leads to frequent rebalancing of workloads across the cluster, causing high I/O and VM motion. Adjusting this setting to a less aggressive level can help reduce unnecessary VM motions and stabilize performance. Reference: Nutanix Bible, Nutanix University NCS-Core 6.8 learning materials
