QUESTION: 69

Which baseline is used to identify a Zombie VM?

VM is powered off for the past 21 days.
Memory usage is less than 1% and memory swap rate is equal to 0 Kbps for the past 21 days.
VM has no logins for the past 21 days
VM has no logins for the past 21 days
Fewer than 30 1/Os and less than 1000 bytes per day of network traffic for the past 21 days

Answer(s): D

Explanation:

The correct answer is D. Fewer than 30 I/Os and less than 1000 bytes per day of network traffic for the past 21 days.

A zombie VM is a type of inactive VM that is powered on but does very little activity. A zombie VM wastes host resources such as CPU, memory, disk, and network that could be used by other VMs. A zombie VM can be identified by using the VM Profile feature in Prism Central. The VM Profile feature analyzes the resource utilization of each VM and assigns it a profile based on its efficiency and impact on other VMs. The profiles are as follows1:

Efficient: The VM is well-provisioned and has optimal resource utilization.

Over-provisioned: The VM has more resources than it needs and has low resource utilization.

Constrained: The VM has less resources than it needs and has high resource utilization.

Inactive: The VM has no resource utilization and is idle or powered off.

Bully: The VM has high resource utilization and causes contention for other VMs.

A zombie VM is a subtype of an inactive VM that meets the following criteria2:

The VM is powered on for the past 21 days.

The VM does fewer than 30 read or write I/Os (total) per day for the past 21 days.

The VM receives or transfers fewer than 1000 bytes per day of network traffic for the past 21 days.

To identify a zombie VM, the administrator can use Prism Central to view the VM Profile dashboard and filter by profile type. The dashboard shows the number of VMs in each profile type, as well as their resource consumption and efficiency score. The administrator can also drill down into each VM to see its detailed metrics and recommendations for optimization.

QUESTION: 70

An administrator manages a cluster and notices several failed components shown in the exhibit.

What two options does the administrator have to run all NCC checks manually? (Choose two.)

Using the Actions drop-down menu in the Health dashboard of Prism Element.
Running ncc health_checks run-alll on the CVM
Using the action action drop-down menu in the Health dashboard of Prism Central
Running noc health_checks run_all on the PC VM

Answer(s): A,B

Explanation:

Prism Element and NCC are two ways to run all NCC checks manually on a Nutanix cluster. Prism Element is the web console that provides management and monitoring capabilities for a single Nutanix cluster. Prism Element has a Health dashboard that shows the status of various components and services in the cluster, such as disks, nodes, CVMs, NCC, and alerts. The Health dashboard also allows the administrator to run NCC checks manually by using the Actions drop-down menu on the right side of the screen. The administrator can choose to run all NCC checks or specific checks based on the category or severity. The NCC checks will run in the background and generate a report that can be viewed or downloaded from the Summary tab. This method is easier and faster than running NCC from the command line on the CVM.

NCC stands for Nutanix Cluster Check, which is a framework of scripts that performs system checks and validations on Nutanix clusters. NCC can detect issues related to hardware, software, configuration, hypervisor, networking, and more. NCC can be run from the command line interface (CLI) of any CVM in the cluster by using the ncc command. To run all NCC checks manually, the administrator can use the command ncc health_checks run_all, which will execute all available checks and display the results on the screen. This method is more comprehensive and detailed than running NCC from Prism Element.

QUESTION: 71

A newly-hired Nutanix administrator was tasked by the CIO to create a single VM on a test network. The network administrator stated that a native VLAN was used on the Cisco TOR switches with the following parameters:

IP address:172,16.1.2

Network Mask: 255.255.255.0

Default gateway: 172.16.1.1

VLAN:1

The same parameters were used to create a network profile on Nutanix, but the when the VM was on ...

What should the Nutanix administrator do to fix this issue?

Nutanix removed support for native VLAN.
Change VLAN field from vlan. 1 to vlan.0.
Enable IPv6 on the VM.
Use DHCP as opposed to static IP

Answer(s): B

Explanation:

A native VLAN is a VLAN that is assigned to untagged traffic on a trunk port of a switch. A trunk port can carry traffic from multiple VLANs, but it needs to have a native VLAN to handle traffic that does not have a VLAN tag. The native VLAN is usually VLAN 1 by default on most switches, but it can be changed to any other VLAN number2.
When creating a network profile on Nutanix, the administrator needs to specify the VLAN ID that matches the VLAN configuration on the physical switch. However, if the network profile uses the same VLAN ID as the native VLAN on the switch, it will cause network connectivity issues for the VMs connected to that network profile. This is because Nutanix AHV uses 802.1Q tagging for all network traffic, including traffic in the native VLAN. The switch will expect untagged traffic in the native VLAN and will drop any tagged traffic in that VLAN3. To fix this issue, the administrator needs to change the VLAN field from vlan. 1 to vlan. 0 in the network profile on Nutanix. This will tell Nutanix AHV to send untagged traffic for that network profile and match the native VLAN configuration on the switch4.

QUESTION: 72

An administrator needs to provide access for a user to view real-time performance metric for all VMs on all clusters across the datacenter.

Which method accomplishes this with the least effort and ongoing maintenance?

Configure IDP authentication and assign the user to the Cluster Admin role in Prism Central.
Configure AD authentication and assign the user to the Viewer role in Prism Element.
Configure AD authentication create a custom role, assign the user to the role, and apply the role to all clusters and VMs

Answer(s): C

Explanation:

The best method to provide access for a user to view real-time performance metrics for all VMs on all clusters across the datacenter is to configure AD authentication create a custom role, assign the user to the role, and apply the role to all clusters and VMs. This method accomplishes this with the least effort and ongoing maintenance because:

AD authentication allows Nutanix Prism Central to integrate with an existing Active Directory (AD) domain and use AD users and groups for authentication and authorization5. This simplifies user management and avoids creating local users on Prism Central.

Creating a custom role allows Nutanix Prism Central to define granular permissions for different actions and entities based on specific needs6. This ensures that users only have access to what they need and nothing more.

Assigning the user to the custom role allows Nutanix Prism Central to grant access rights for that user based on the role definition7. This avoids assigning permissions individually for each user.

Applying the role to all clusters and VMs allows Nutanix Prism Central to propagate the access rights for that role across all entities in scope8. This ensures that users can view real-time performance metrics for all VMs on all clusters without having to configure each entity separately.
