Nutanix Certified Professional - Multicloud Infrastructure v6.10 NCP-MCI Exam Practice Test
Question 1
Refer to Exhibit:
An administrator is looking at the memory cluster runway diagram as shown in exhibit, in Prism Central. The environment has three hosts with the following configuration:
CPU: 2x Intel Xeon Gold (8 cores, 2.6 GHz)
RAM: 256 GB per host
Storage: SSDs and HDDs
The Intelligent Operations feature has been active for one month, but no further configurations were applied.
What does the dotted red line mean?
Answer : C
he Prism Central Memory Cluster Runway Diagram provides insights into memory usage trends, predicting how long the cluster can sustain workloads before exhausting resources.
The solid blue area represents the actual memory consumption over time.
The dotted red line represents the effective memory capacity limit based on the cluster's current configuration.
Analyzing the Dotted Red Line
The dotted red line is labeled 'Effective Capacity: 503.22 GiB', which means:
It is the total usable memory capacity in the cluster after considering hypervisor overhead, redundancy settings, and failover capacity.
This value is not a hard limit but an indication of the available memory before potential performance issues occur.
Evaluating the Answer Choices
(A) It is the default trend analysis static threshold that can be manually set. (Incorrect)
The dotted red line is not a static threshold that an administrator can manually configure.
Trend analysis in Prism is dynamic and based on workload history and projections.
(B) It is the maximum memory the administrator can assign to VMs. (Incorrect)
Administrators can oversubscribe memory beyond the dotted red line if memory overcommitment is enabled.
However, oversubscribing memory beyond effective capacity may impact performance.
(C) It is the calculated memory oversubscription limit for currently running VMs. (Incorrect)
The dotted red line does not represent oversubscription limits.
Memory oversubscription depends on hypervisor memory ballooning, compression, and swapping mechanisms, which are not directly shown here.
(D) It is the usable capacity based on cluster configuration options. (Correct Answer)
The dotted red line (503.22 GiB) represents the actual usable memory available in the cluster after factoring in system overhead.
This value is determined by:
Total physical memory (256 GB per host 3 hosts = 768 GB)
Memory reserved for hypervisor and system processes
Cluster failover and redundancy settings
Intelligent Operations capacity analysis
Multicloud Infrastructure Reference & Best Practices
Prism Central's 'Runway' feature provides AI-driven trend analysis for memory, CPU, and storage capacity.
The effective capacity limit helps administrators make proactive scaling decisions before resources become critical.
To increase the memory runway, administrators can:
Optimize VM memory allocation.
Add more hosts to the cluster.
Enable memory deduplication and compression (if available).
Question 2
An administrator is experiencing performance issues within a VM and believes that more vCPU should be added to the specific VM. The cluster as a whole appears to be performing well.
Which two metrics should be analyzed to determine if adding more vCPUs is warranted? (Choose two.)
Answer : A, B
Question 3
Due to requirements from the network team, a Nutanix administrator must create User VMs on VLAN 10 on multiple AHV clusters.
What network configuration should the administrator consider in order to ensure consistent connectivity for User VMs on VLAN 10?
Answer : C
Question 4
An administrator wants to disable password-based SSH access for the nutanix user on a CVM to improve security.
What action should the administrator take?
Answer : C
Enabling 'Cluster Lockdown' in Nutanix is the best security measure to prevent password-based SSH logins.
Option C (Enable Cluster Lockdown) is correct:
Cluster Lockdown disables password-based SSH and requires key-based authentication.
Option A (Rename the nutanix user) is incorrect:
The Nutanix user is a system account and cannot be renamed.
Option B (Block port 22) is incorrect:
This would prevent all SSH connections, including key-based logins, making administration difficult.
Option D (Delete the nutanix user) is incorrect:
The nutanix user is required for system operations and cannot be removed.

Question 5
An administrator is tasked with optimizing a VM's storage to leverage compression features. Currently, vDisks are in a storage container default-container-91753272703541 that has no optimization activated. The administrator must move the VM's storage to the storage container Production.
What is the most efficient way to achieve this operation?
Answer : C
Question 6
What is the best way to automate the deployment of 100 Linux VMs with similar configurations but different hostnames, local configurations, and install packages?
Answer : B
Question 7
An administrator using a dark site deployment for LCM is attempting to upgrade to the latest BIOS.
After completing an inventory scan, the administrator does not see the expected BIOS version available for upgrade.
What is the most likely reason the latest BIOS is not shown?
Answer : B
In a dark site deployment, LCM does not automatically fetch updates from the internet. The administrator must manually upload compatibility bundles.
Option B (The latest compatibility bundle has not been uploaded) is correct:
The compatibility bundle contains firmware mappings, allowing LCM to detect the correct BIOS version.
Option A is incorrect:
AOS does not need to be upgraded first for a BIOS update.
Option C is incorrect:
The BMC firmware does not always need updating before BIOS updates.
Option D is incorrect:
In a dark site deployment, LCM does not rely on an internet connection, so webserver access is not required.
