Why has an anomaly been triggered?

  1. Because the CPU usage crossed the blue band.
  2. Because the blue band range increased over the last 2 days
  3. Because the CPU usage dropped belon' 20%
  4. Because the CPU usage reached 100%

Answer(s): A

Explanation:

Nutanix leverages a method for determining the bands called `Generalized Extreme Studentized Deviate Test'. A simple way to think about this is similar to a confidence interval where the values are between the lower and upper limits established by the algorithm.

Another web source3 shows an example of how anomaly detection works in Nutanix Prism Central. In the video, you can see that when the observed value of a metric deviates significantly from the predicted value based on historical data, an anomaly event is triggered and displayed on a chart.

Therefore, by comparing the observed values with the predicted values based on historical data, Nutanix anomaly detection can identify abnormal behavior and alert you accordingly.

An administrator needs to enable inline deduplication for a pre-existing storage container.
When trying to enable deduplication on the storage container. this feature is grayed-out.

What is the reason for this behavior?

  1. Replication Factor 1 is configured on the storage container.
  2. The cluster has less than 5 nodes which is the minimum node-count to enable deduplication.
  3. Capacity reservation is not enabled on the storage container.
  4. The cluster has hybrid storage and deduplication is supported only on all-flash clusters.

Answer(s): D

Explanation:

Nutanix supports two types of deduplication: post-process and inline. Post-process deduplication runs periodically on a schedule and can be enabled on any cluster. Inline deduplication runs in real time before data is written to disk and can be enabled only on all-flash clusters.

Therefore, by checking the type of storage and the type of deduplication, you can determine if you can enable inline deduplication on a storage container or not.

Nutanix inline deduplication is a feature that reduces the stored size and avoids duplicate data on a storage container. It is recommended only on some specific scenarios, such as when using Nutanix Files or virtual desktop infrastructure (VDI) workloads.

An administrator is trying to create a custom alert policy for all VMs.

Why is the Alert warning if field greyed cut?

  1. The Alert critical if threshold is set.
  2. The Behavioral Anomaly threshold is set.
  3. The Enable Policy option checked.
  4. The Auto resolve alerts option is checked.

Answer(s): B

Explanation:

when you create a custom alert policy, you can choose between two types of thresholds: Static Threshold and Behavioral Anomaly. Static Threshold allows you to set a fixed value for the metric that triggers the alert. Behavioral Anomaly allows you to use machine learning to detect abnormal behavior based on historical data.

If you select Behavioral Anomaly as the threshold type, you cannot set a warning level for the alert. You can only set a critical level that indicates how much deviation from normal behavior is considered an anomaly. Therefore, the Alert warning if field is greyed out when you select Behavioral Anomaly.

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?

  1. Only one interface is available on the selected hosts.
  2. Interfaces must be connected to the network before they can be assigned.
  3. The disconnected interfaces are currently assigned to virtual switch 0,
  4. Interfaces must be assigned to virtual switches via the cli

Answer(s): B

Explanation:

In Nutanix AHV, when creating a virtual switch and trying to add network interfaces (NICs) to it, the NICs must be connected to the network before they can be selected and assigned to the switch. If the interfaces are showing as disconnected, the system will not allow them to be added to a virtual switch because it cannot verify their operational status or the presence of a live network connection.

It is a standard requirement for the interfaces to have physical connectivity (i.e., network cables plugged in and connected to a live switch port) so that the AHV host can detect the link status as up. Once the interfaces are connected and recognized by the host, they can then be added to a virtual switch in the Nutanix AHV.

It's important to note that while the command-line interface (CLI) is indeed a powerful tool for managing network configurations on AHV hosts, and some configurations do indeed require CLI, the inability to select disconnected interfaces is not specifically a limitation that requires the use of CLI to overcome. The focus should be on ensuring that the physical connectivity is established for the interfaces in question.

This behavior is consistent with networking best practices and Nutanix's network configuration guidelines, as detailed in the Nutanix AHV Networking Guide. This guide explains the requirements and procedures for configuring virtual switches and managing NICs in a Nutanix AHV environment.
