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

Answer : B

The task that needs to be performed when time is not synchronizing properly after deploying a cluster is NTP configuration. In the Nutanix Multicloud Infrastructure (NCP-MCI) 6.5, Network Time Protocol (NTP) is used to synchronize the system time across all the nodes in a cluster. If the time is not synchronizing properly, it indicates that there might be an issue with the NTP configuration. Therefore, checking and correcting the NTP configuration would be the appropriate action to resolve this issue. The other options like DNS configuration, HA configuration, and SMTP configuration are not directly related to time synchronization in a cluster.

According to the Nutanix Support & Insights web search result4, Prism Central can be installed manually on an AHV cluster by using three disk images: boot, home, and data. These disk images must be downloaded from the portal for the Prism Central VM and uploaded to an image service on the AHV cluster. The boot image contains the operating system and kernel for Prism Central. The home image contains the configuration files and logs for Prism Central. The data image contains the database and application files for Prism Central.

Answer : C

According to the Nutanix Support & Insights web search result1, erasure coding is a data savings technique that utilizes stripes and parity calculation in a Nutanix cluster. Erasure coding increases the usable capacity on a cluster by reducing the replication factor of data blocks. Instead of replicating data, erasure coding uses parity information to rebuild data in the event of a disk or node failure.Erasure coding can save up to 50% of storage space compared to replication factor 2, and up to 75% compared to replication factor 32.

Provision storage on the Nutanix cluster by creating a volume group. Create a client whitelist to enable access to the volume group by using the IP addresses or client initiator IQNs in a whitelist (as part of the volume group configuration). Create a secret for the volume group if you are using CHAP authentication.

Answer : A, B, C

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.

Answer : B

According to the web search results, a consistency group is a group of related applications or services that must be recovered together in order to work properly, and this means more than being recovered at the same time67.They also typically need to be recovered to the same point in time6.Therefore, to meet the requirement of protecting all VMs of a multi-tier application at the same time, the administrator must create a consistency group for the application and place all VMs in it8.This way, the administrator can apply data protection policies and schedules to the entire consistency group as a single unit8.
