Nutanix NCP-MCI Nutanix Certified Professional - Multicloud Infrastructure v6.5 Exam Practice Test

Answer : C

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.

Answer : B

When a node with Erasure Coding fails, the cluster will automatically rebuild the missing data using replication factor (RF) 2 or 3, depending on the cluster configuration.This means that the data that was previously stored using Erasure Coding will now be stored using full copies, which may increase the amount of data stored in the SSD tier1.

Answer : C

According to theNutanix Files Guide, Nutanix Files instances are composed of a set of VMs (called FSVMs). Files requires at least three FSVMs running on three nodes to satisfy a quorum for high availability. By default, Files deploys three FSVMs when you create a file server instance.

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.

Answer : B

The best way for the administrator to limit the amount of storage space that data stored in a single container can consume is to set an advertised capacity for the container. This will ensure that the data stored in the container doesn't exceed the set limit, and it will also help prevent any potential performance issues due to resource contention. Additionally, the administrator should consider thick provisioning the container, which will pre-allocate the amount of storage space that can be used by the container. This will help ensure that the data stored in the container doesn't exceed the advertised capacity.

Answer : C, D

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.
