NEW QUESTION # 56
Monitoring data shows stable CPU and memory usage, but a user VM remains slow.
Which area should be investigated next?
Answer: D
Explanation:
Once CPU consumption, CPU contention and memory utilization have been reviewed and found stable, storage latency becomes the next relevant performance domain. A VM can have adequate compute resources yet remain slow because guest read or write operations are waiting for the storage path. High latency may arise from workload contention, abnormal I/O patterns, a storage-controller issue, or an underlying infrastructure condition.
Prism exposes VM and infrastructure metrics including IOPS, bandwidth, read latency, write latency and total I/O latency. The administrator should correlate the VM's latency with its IOPS and throughput, then compare those values with storage-container, host and cluster-level metrics over the same interval. This determines whether the delay is isolated to the VM or reflects a broader storage condition.
License expiration may affect access to licensed features, but it is not the primary diagnostic explanation for an actively running VM's I/O responsiveness. RBAC controls administrative permissions rather than guest workload performance. Container sizing is not a standard immediate troubleshooting metric; the measurable symptom to examine first is latency.

NEW QUESTION # 57
Which bond type is the default for newly created AHV clusters?
Answer: D
Explanation:
Active-Backup is the default bond configuration for newly created AHV clusters. In this mode, one physical uplink actively forwards traffic while another eligible uplink remains available as a standby. If the active link fails, AHV moves traffic to the backup link, providing straightforward network redundancy without requiring LACP or a switch-side link-aggregation configuration.
The principal advantage of Active-Backup is operational compatibility. Because only one uplink forwards traffic at a given time, the upstream switch ports do not need to be combined into a link aggregation group.
However, the configuration does not aggregate the bandwidth of multiple physical NICs during normal operation.
Balance-slb provides active-active source load balancing using MAC pinning and can improve aggregate host bandwidth without requiring LACP. Balance-tcp uses active-active LACP and requires matching configuration on the physical switches. Both are deliberately configured alternatives rather than the default.
"No Uplink Bond" would eliminate bond-level redundancy and is not the standard newly created cluster configuration.

NEW QUESTION # 58
What is the role of Nutanix Insights?
Answer: B
Explanation:
Nutanix Insights is a predictive health and support-automation service that analyzes diagnostic telemetry received from registered Nutanix environments. Its primary function is to identify infrastructure-health gaps, detect known risks, recommend corrective actions, and streamline the support process before an issue becomes operationally disruptive. Nutanix states that system-level diagnostic telemetry is analyzed to produce actionable infrastructure insights. Insights can also automate support-case creation, log collection, and the assignment of appropriate support resources.
Option A therefore describes the service accurately. Real-time CPU and memory monitoring in option B is primarily performed through Prism performance dashboards, VM metrics, and analysis charts. Workload migration between environments is associated with technologies such as Nutanix Move and Nutanix Cloud Clusters rather than Insights. Initial node imaging and cluster creation in option D are Foundation functions.
Insights normally works with Nutanix Pulse, which supplies the required diagnostic information. This makes Insights a proactive support capability, not merely another local monitoring dashboard.

NEW QUESTION # 59
An administrator needs to increase the available storage of an existing AHV virtual machine by adding a new vDisk.
Which method is supported to perform this task?
Answer: D
Explanation:
An administrator can add storage directly to an existing AHV VM by editing its configuration and selecting Add New Disk. In the disk configuration, the administrator specifies the device type, disk size, storage container, and supported controller or bus settings. The new vDisk is then attached to the VM and presented to the guest operating system, where it can be initialized, partitioned, and formatted.
Creating another VM is unnecessary because AHV supports modifying the virtual hardware of an existing VM. Increasing a host's local disk does not directly create guest storage; physical disks contribute capacity to the Nutanix distributed storage fabric rather than being individually assigned to a VM. Similarly, changing the size of a storage pool is an infrastructure-capacity operation and does not attach a new virtual disk to the selected workload.
A storage container holds the vDisk and provides access to the cluster's distributed storage resources.
Selecting the appropriate container during disk creation is therefore part of the supported workflow.

NEW QUESTION # 60
On an AHV host, what is the factory-configured default native Linux bridge?
Answer: A
Explanation:
The factory configuration of an AHV host includes a native Linux bridge named virbr0. This bridge is separate from the Open vSwitch components used for normal AHV workload and infrastructure networking.
Administrators should preserve the factory-defined bridge unless a specific Nutanix procedure instructs otherwise.
The similarly named components in the other options serve different purposes. br0 is the factory-configured default Open vSwitch bridge. It contains the physical uplink interfaces and internal ports used by the AHV networking architecture. vs0 is the default AHV virtual-switch configuration associated with br0; it is a logical virtual-switch object rather than a native Linux bridge. ovsbr0 is not the factory-default bridge name in the documented AHV configuration.
This distinction is operationally important when interpreting commands such as ovs-vsctl, Linux bridge utilities, interface listings, or network-troubleshooting output. Confusing virbr0 with br0 can lead an administrator to modify the wrong networking component and potentially disrupt host, CVM, or guest connectivity. Nutanix documentation explicitly identifies the native Linux bridge as virbr0. Reference: AHV
