Question 11

Report Export Collapse

The administrator recently had a node fail in an AHV Nutanix cluster. All of the VMs restarted on other nodes in the cluster, but they discovered that the VMs that make up a SQL cluster were running on the failed host. The administrator has been asked to take measures to prevent a SQL outage in the future.

What affinity option will prevent the SQL VMs from running on the same hos?

VM-VM anti-Affinity policy
VM-VM anti-Affinity policy
Create Affinity Category
Create Affinity Category
VM-Most Affinity policy
VM-Most Affinity policy
Create Affinity Project
Create Affinity Project
Suggested answer: A
Explanation:

A VM-VM anti-Affinity policy is a rule that ensures that two or more VMs don't run on the same AHV host. It's useful when an application provides HA and an AHV host can't be an application's single point of failure1. In this case, the SQL cluster VMs should have a VM-VM anti-Affinity policy configured to prevent them from running on the same host and causing an outage if that host fails. A VM-VM anti-Affinity policy can be created using the aCLI commands2. The other options are not relevant for this scenario.

An administrator needs to increase bandwidth available to the AHV host and to the CVM.

How should the administrator complete this task?

In Prism, update vs0 to change the configuration to Active-Active.

In Prism, create a vsl interface and add any remaining uplinks.
Use manage-ovs commands to create br1 and add any remaining uplinks
Use manage-ovs commands to create br1 and add any remaining uplinks
Suggested answer: B
Explanation:

The default network configuration for AHV hosts and CVMs is a bond named br0-up with two or more uplinks in active-backup mode. This means that only one uplink is active at a time, while the others are in standby mode. This provides high availability, but not load balancing or increased bandwidth. To increase the bandwidth available to the AHV host and the CVM, the administrator can change the bond mode to Active-Active, which allows all uplinks to be used simultaneously. This can be done using the manage-ovs commands on each AHV host.The steps are as follows1:

Log in to the AHV host using SSH.

Enter maintenance mode on the CVM by runningallssh 'cluster status | grep -i cvm | grep -i down'.

Change the bond mode to Active-Active by runningmanage_ovs --bond_mode active-active update_uplinks br0-up <uplink_list>, where<uplink_list>is a comma-separated list of uplink interfaces (for example, eth0,eth1).

Verify the bond mode by runningmanage_ovs show_uplinks.

Exit maintenance mode on the CVM by runningallssh 'cluster start'.

Which inefficient VM Profile can be used to identify a VM that consumes too many resources and causes other VMs to starve?

Over-provisioned VM
Over-provisioned VM
Inactive VM
Inactive VM
Bully VM
Bully VM
Constrained VM
Constrained VM
Suggested answer: C
Explanation:

A bully VM is a VM that consumes too many resources and causes other VMs to starve. A bully VM can affect the performance and availability of other VMs on the same host or cluster by hogging CPU, memory, disk, or network resources.A bully VM can be identified by using the VM Profile feature in Prism Central2. 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 follows3:

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.

To identify a bully 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.

What is he recommended approach for a constrained VM?

Reboot the VM
Reboot the VM
Delete the VM.
Delete the VM.
Increase the VM resources.
Increase the VM resources.
Decrease the VM resources
Decrease the VM resources
Suggested answer: C
Explanation:

A constrained VM is one that does not have enough resources for the demand and can lead to performance bottlenecks.A VM is considered constrained when it exhibits one or more of the following baseline values, based on the past 21 days: CPU usage > 90% (moderate), 95% (severe) CPU ready time > 5%, 10% Memory usage > 90%, 95% Memory swap rate > 0 Kbps1.To provide adequate host resources, resize (increase) the constrained VMs1.

An administrator wants to expand the Failure Domain level of a cluster.

What two options are available? (Choose two.)

Node
Node
Data Center
Data Center
Block
Block
Rack
Rack
Suggested answer: C, D
Explanation:

Nutanix clusters are resilient to a drive, node, block, and rack failures because they use redundancy factor 2 by default, allowing Nutanix clusters to self-heal2.Failure scenarios can be thought of in terms of fault domains, which are the physical or logical parts of a computing environment or location that are adversely affected when a device or service experiences an issue or outage3.There are four fault domains in a Nutanix cluster: Disk, Node, Block, and Rack4. Block and Rack are two options that are available for expanding the failure domain level of a cluster.Block fault tolerance is enabled by default and ensures that data is replicated across different blocks in a cluster5.Rack fault tolerance has to be configured manually and ensures that data is replicated across different racks in a cluster4.

Prims Central is using a three-node scale-out deployment
Suggested answer: C
Explanation:

Flow Networking is a feature that enables software-defined networking for AHV clusters. It allows users to create and manage virtual private clouds (VPCs), subnets, and network services such as NAT, DHCP, routing, and VPN. Flow Networking also supports service insertion and chaining, which enables integration with third-party network functions such as firewalls and load balancers. Flow Networking is built on top of the microservices infrastructure (MSP) in Prism Central, which provides the platform for running various Nutanix services such as Calm, Karbon, and Objects.Therefore, to enable Flow Networking, the MSP must be enabled first on Prism Central1.The MSP can be enabled from the Prism Central settings page or from the command line interface (CLI) of the Prism Central VM2. Enabling the MSP will also enable Flow Microsegmentation, which is another feature that provides network security and visibility for AHV clusters.

System Non-Root Partition Usage shows a warning or critical alert The administrator needs to change the frequency of checks and alerts to respond more quickly.

Where in Prism Element should the administrator change the frequency of checks and alerts?

Health Dashboard > Manage Crocks > Frequency
Health Dashboard > Manage Crocks > Frequency
Alerts Dashboard > Manage Checks > Schedule
Alerts Dashboard > Manage Checks > Schedule
Health Dashboard > Manage Checks > Schedule
Health Dashboard > Manage Checks > Schedule
Alerts Dashboard > Manage Checks > Frequency
Alerts Dashboard > Manage Checks > Frequency
Suggested answer: C
Explanation:

According to the Nutanix Support & Insights web search result1, the administrator can change the frequency of checks and alerts for the System Non-Root Partition Usage in Prism Element by going to the Health Dashboard > Manage Checks > Schedule. The administrator can select the check name, such as disk_usage_check, and click on Edit Schedule. The administrator can then choose the desired frequency, such as every 15 minutes, every hour, or every day, and click on Save. This will change how often the check runs and alerts are generated.
