Nutanix NCP-MCI-6.5 問題集

質問 1：
CPU utilization climbs above 90% on several VMs. This causes performance degradation for a business-critical application.
How can alerts be configured to notify the administrator before VM CPU utilization hits 90%?
A. On a CVM, use ncli to set the VM CPU Check threshold for the critical VMs to a value below 90%.
B. On the Health dashboard, locate the VM CPU Check and lower the alert threshold below 90%.
C. On a CVM, configure a cron job to run the VM CPU Check more frequently and email the result.
D. On the Alerts dashboard, ensure that the VM CPU usage alert is not set to auto-resolve.
正解：B

質問 2：
An administrator manages an AHV cluster that is dedicated to a dev/test environment. The administrator receiving complaints from users that they are unable to create new VMs on the cluster.
After the reviewing the cluster, the administrator finds that the memory resources are almost fully utilized, with many VMs over-provisioned on memory.
What option is the most efficient resolution to enable additional VMs to be created?
A. Disable HA Reservation on the cluster.
B. Upgrade the nodes with additional memory DlMMs.
C. Enable Memory Overcommit on the over-provisioned VMs.
D. Enable Memory HA on the over-provisioned VMs.

質問 5：
Refer to Exhibit:

An administrator is attempting to create an additional virtual switch on a newly deployed AHV cluster, using the two currently disconnected interfaces. The administrator is unable to select the disconnected interfaces when creating the virtual switch.
What is the likely cause of this issue?
A. Interfaces must be connected to the network before they can be assigned.
B. Interfaces must be assigned to virtual switches via the cli
C. Only one interface is available on the selected hosts.
D. The disconnected interfaces are currently assigned to virtual switch 0,

質問 6：
An administrator has created several custom alert policies, which are applied to the same entities. Prism Central displays a message that a similar policy exists.
In what order of precedence are overlapping policies evaluated?

正解：

Explanation:
First Preference:
* Policy is applied to a specific entity
2nd Preference:
* Policy is applied to an entity type in a category
3rd Preference:
* Policy is applied to an entity type in a cluster
4th Preference:
* Policy is applied to all entities of an entity type
Comprehensive Detailed Explanation with References:In Nutanix Prism, when multiple alert policies are created and applied to the same entities, the policies are evaluated based on their specificity. The order of precedence from highest to lowest is as follows:
* Policy is applied to a specific entity: Custom alert policies that are applied to specific entities take precedence over those applied to broader categories. This is because the more specific policy is usually created with a particular context or requirement in mind for that entity.
* Policy is applied to an entity type in a category: The next level of precedence is given to policies that are applied to all entities of a certain type within a specific category. Categories allow grouping of entities based on certain criteria, and policies applied here are more specific than to an entire cluster or entity type.
* Policy is applied to an entity type in a cluster: This refers to policies that are applied to all entities of a certain type within a specific cluster. This is more general than the above two but still targets a specific cluster environment.
* Policy is applied to all entities of an entity type: The lowest precedence is given to policies that are broadly applied to all entities of a particular type across the entire Nutanix environment.
This order ensures that the most specifically targeted policies are given priority, which allows for fine-tuned control and customization of alert policies. The details of alert policy precedence are typically covered in the Nutanix Prism Central Guide and the documentation related to Prism Central's alerting and policies.
