Which three steps must the administrator take to increase throughput to the host? (Choose three.)
Correct Answer:ABC
These are the three steps that the administrator must take to increase throughput to the host. According to the network diagram, the host has two 10Gb interfaces and two 1Gb interfaces in the default bond, but only one of the 10Gb interfaces is connected to a switch. The other 10Gb interface is disconnected and has a red ??X?? on it. The two 1Gb interfaces are also disconnected and have dotted lines. This means that the host is using only one 10Gb interface for all its network traffic, which limits its maximum bandwidth to 10 Gbps.
To increase the throughput, the administrator should connect both 10Gb interfaces to the physical switch, preferably to different switches for redundancy and high availability. This will allow the host to use both 10Gb interfaces for network traffic, which can increase its maximum bandwidth to 20 Gbps. However, this also requires changing the bond mode from active-backup to balance-slb or balance-tcp, which are load balancing modes that distribute network traffic across multiple interfaces based on source MAC address or TCP session1. The default bond mode of active-backup only uses one interface at a time and switches to another interface only when the active one fails2.
Finally, the administrator should remove any 1Gb interfaces still connected from the default bond, as they are not needed and may cause performance issues or conflicts with the load balancing modes. The 1Gb interfaces can be used for other purposes, such as management or backup networks, by creating separate bonds or bridges for them3. Alternatively, they can be left disconnected if they are not required.
During an AHV upgrade, an administrator finds that a critical VM was powered off rather than migration to another host.
Which scenario explains this behavior?
Correct Answer:D
An agent VM is a special type of VM that is used for running services or applications that are not affected by high availability (HA) events or host maintenance. An agent VM is never migrated to any other host in the cluster. If an HA event occurs or the host is put in maintenance mode, agent VMs are powered off and are powered on on the same host once that host returns to a normal state. This behavior is different from regular VMs, which are migrated to another host in the cluster if possible, or restarted on the same host if not possible1.
Therefore, during an AHV upgrade, an administrator may find that a critical VM was powered off rather than migrated to another host if the VM was marked as an agent
VM. This can be done either from the Prism web console by selecting the Use this VM as an agent VM option in the Update VM dialog box, or from the aCLI by using the vm.create or vm.update commands with the agent_vm=true parameter2. To avoid this situation, the administrator should ensure that any critical VMs are not marked as agent VMs before starting the AHV upgrade.

Which capability refers to the storage of VM data on the node where the VM is running and ensure that the read I/O does not have to traverse the network?
Correct Answer:B
Data locality is the capability of storing VM data on the node where the VM is running and ensuring that the read I/O does not have to traverse the network. Data locality is a unique feature of Nutanix that provides high performance and low latency for VMs by minimizing network traffic and crosstalk. Data locality works by writing one copy of the data local to the VM and the other copy (or copies) on other nodes. When a VM migrates to another node, Nutanix also moves its data to the new node and serves all I/O requests locally. Data locality also adapts to changing workloads and access patterns by dynamically moving data to where it is needed most1.
An administrator wants to receive an environment summary report when a host failure occurs.
Which action would address the administrator??s need?
Correct Answer:D
"Playbook allows you to define a trigger that results in the execution of an action or a series of actions. A trigger may be an event that occurs in the system, such as an alert or a request made by you. The resultant actions that you configure can be VM actions, communication actions, alert actions, or report actions." https://portal.nutanix.com/page/documents/details?targetId=Intelligent-Operations-Guide- vpc_2023_3:ssp-report-management-ssp-pc- c.html#:~:text=The%20environment%20summary%20report%20provides,is%20registered
