Nutanix NCP-MCI-7.5 Practice Test Questions Answers

The decisive metric in the iostat output is %iowait = 83.20. In Linux performance interpretation, such a high iowait value means the CPU is spending most of its time waiting for disk I/O operations to complete rather than actively executing user or system work. On a Nutanix CVM, that strongly suggests the storage path is the bottleneck at that moment, whether due to backend disk saturation, contention, or broader storage subsystem latency. Since user CPU and steal are both low, the issue is not primarily compute pressure or hypervisor scheduling contention. Therefore, A is the most accurate description. ( Nutanix )

This is a classic Nutanix troubleshooting interpretation question. If the output had shown high %steal, then hypervisor contention would be a stronger candidate. If %system and %user were both very high, compute load from services would be more likely. But with the overwhelming majority of time in iowait, the signal points toward delayed storage completion. In operational terms, the next steps would usually involve checking CVM disk metrics, Stargate performance, storage latency, and possibly the health of the underlying drives. The evidence in the output supports a storage wait condition, which is exactly what option A says. ( Nutanix )

Nutanix documentation for Prism Central deployment states that single Prism Central VM deployments are supported in Small, Large, or X-Large sizes, and that a single-VM deployment can later be scaled out. Since X-Small is not the supported minimum deployment size in this documented model, the minimum supported size is Small. That makes A correct.

This question is really checking whether the administrator understands the starting point for a scale-out-capable Prism Central design. The existence of larger sizes does not change the minimum supported entry point. Nutanix’s documentation is explicit that a single Prism Central VM can begin at Small and later be expanded if more scale or resiliency is needed. Therefore, for a single-node Prism Central deployment with future scale-out potential, the correct answer is Small.

For AHV, when enabling LACP, Nutanix documentation specifies the Active-Active bond type, also described as balance-tcp. Nutanix explicitly ties LACP and link aggregation behavior to the Active-Active configuration and notes that this configuration sets LACP fallback to Active-Backup on AHV hosts. That makes C the correct bond type for an LACP-enabled design. ( Nutanix Portal )

It is also important to understand why Active-Active with MAC Pinning is wrong here. Nutanix documentation states that the MAC-pinning / balance-slb style must not be used with link aggregation protocols such as LACP. So even though both options sound like they distribute traffic, only one is compatible with LACP. Active-Backup provides redundancy, but not the LACP behavior being requested. “No Uplink Bond” obviously does not meet the requirement. Even without the missing exhibit from the uploaded file, the Nutanix networking documentation makes the intended answer clear: Active-Active is the bond type used when enabling LACP on AHV.

Nutanix documentation on rebuild capacity reservation and resilient capacity emphasizes that some storage space must remain effectively protected so the cluster can recover from failures and maintain resiliency. If a cluster consumes all capacity beyond that protected threshold, it can reach a point where it no longer safely accepts writes because continuing to do so would violate resiliency guarantees. The symptoms in the question—stopped accepting writes and VM outages—align with a cluster hitting its resilient capacity limit, not merely an EC optimization limit. ( Nutanix )

This distinction matters. Erasure coding limits affect efficiency opportunities, but they do not by themselves explain the cluster refusing writes. A degraded container after a node failure may contribute to pressure, but the wording centers on cluster-wide behavior after rebuild-capacity reservation is enabled. Nutanix’s resiliency logic is designed to protect the cluster from entering an unsafe state, and one enforcement mechanism is to stop admitting additional writes when resilient capacity has been exhausted. Therefore, the most likely cause is C: the cluster has reached its resilient capacity limit. ( Nutanix )

In Prism Central, Runway Analysis is not a simple reading of current utilization; it is a forecast based on historical consumption trends. Nutanix documentation explains that capacity planning and runway use machine learning and historical resource behavior to estimate when CPU, memory, or storage will run out. That means a cluster can still show only 60% memory used today and yet have a short memory runway if the memory-consumption trend has been climbing steadily and rapidly over recent history. In this scenario, the most likely reason for only 12 days of runway is sustained growth in memory use over the historical observation period. ( Nutanix )

The distractors do not fit the documented behavior as well. Nutanix does support scenario modeling, but a low runway in the standard view is primarily a forecast outcome, not a default penalty for missing history or a result of guaranteed HA mode by itself. HA reservations can reduce available effective capacity, but the wording of the question points to forecasting logic rather than static reservation math. Since Nutanix runway is based on actual consumption trends, the answer that best explains a low runway despite moderate present-day utilization is that memory usage has been continuously increasing, which is option B.
