NCS-CORE practice question 26 of 35

A systems administrator needs to add more VMs to their Nutanix cluster. Which two actions should the administrator perform to determine if the current cluster can accommodate the new VMs? (Choose two.)

Answer options
A: Perform an Inventory with Life Cycle Management.
B: Determine utilization with Cluster Runway. Correct answer
C: Enable Deduplication and Erasure Coding.
D: Utilize Optimize Resources for VM efficiency. Correct answer
Correct Answer:
B. Determine utilization with Cluster Runway.; D. Utilize Optimize Resources for VM efficiency.
Explanation

To determine if a cluster can host more VMs, an administrator must perform capacity planning. The primary Nutanix tool for this is Cluster Runway (B), which is available in Prism. It analyzes historical usage of CPU, memory, and storage to forecast how many days of capacity remain. This directly answers whether there is room for growth. A complementary action is to Utilize Optimize Resources (D). This feature, powered by X-Fit, identifies inefficiently configured VMs (e.g., oversized, inactive). By right-sizing these existing VMs, an administrator can reclaim wasted resources, thereby increasing the available capacity for new VMs.

Why Incorrect

Perform an Inventory with Life Cycle Management.: Life Cycle Management (LCM) inventories and updates software and firmware versions. It does not analyze or forecast resource capacity for workloads. Enable Deduplication and Erasure Coding.: These are storage efficiency features. While they can increase usable storage capacity, they do not provide a holistic capacity analysis for CPU and memory resources.
