Nutanix NCS-Core Practice Questions

Explanation: For a Nutanix cluster configuration that simplifies future deployments and expansions, disabling multicast and broadcast flood optimizations (A) and using a tagged VLAN for the CVM and hypervisor hosts (C) are the best practices. Disabling these optimizations helps in reducing unnecessary network traffic and potential broadcast storms in a growing environment. Using tagged VLANs for CVM and hypervisor hosts ensures proper network segmentation and scalability, allowing for easier management and expansion without reconfiguring the native network setup for each expansion or deployment.References: Nutanix Network Configuration Best Practices, Nutanix Deployment Guide.

Explanation: After an onsite cluster deployment, the As-Built Guide is a crucial document that provides detailed information about the final configuration of the system. However, certain data in the As-Built Guide might require adjustment or might be missing completely. In this case, the Nutanix Node Port Layout (Option A) and the Physical Rack Layout (Option C) are two data that might require adjustment or might be missing completely. The Nutanix Node Port Layout provides a visual representation of the network connections for each node in the cluster, while the Physical Rack Layout provides a visual representation of the physical arrangement of the nodes in the rack. Both of these data are crucial for understanding the physical and network configuration of the cluster, and any inaccuracies or omissions in these data could lead to confusion or issues in the future. Therefore, the consultant should ensure that the Nutanix Node Port Layout and the

Explanation: If the Foundation VM fails to boot and other methods need to be considered, the best alternative is the Foundation Applet. This lightweight tool runs on a laptop or other device and doesn't require booting a VM, providing a straightforward method to image Nutanix hardware, particularly useful in situations where hardware constraints or other issues prevent the use of a full Foundation VM.

Explanation: In the scenario where SQL queries are running slower post-migration, creating multiple TempDB data files is a recognized best practice for optimizing SQL Server performance, especially when dealing with high transaction rates or complex queries. This approach helps in distributing the I/O load across multiple files and drives, reducing the contention and wait times associated with TempDB, which is a common bottleneck in SQL Server environments. Enabling autogrowth ensures that these files can dynamically grow as needed, which helps in handling unexpected increases in database activity without manual intervention.

Explanation: The CVM IP address is a hard requirement for deploying a Nutanix cluster. Each CVM must have a unique IP address assigned to it as this IP address is critical for cluster operations, including data replication, management activities, and communication between CVMs and hypervisors. The other options, while important for various functionalities, do not represent a hard requirement for initial deployment.
