Question 1

An administrator migrates a VM onto a new Nutanix cluster- After the migration, the administrator observes the following conditions:

* Cluster memory utilization: 64%

* Cluster CPU utilization: 19%

* Cluster storage utilization. 32%

* Average VM CPU utilization: 25%

* Average VM CPU ready%: 24%

* Average VM memory utilization: 60%

Which two changes should the administrator make to improve VM performance? (Choose two.)



Answer : A, C

According to the CPU (%) - VMware Docs web search result2, one of the possible causes of high CPU ready % is over-provisioning vCPUs for a VM or having too many VMs on a host. CPU ready % indicates the percentage of time that the VM was ready, but could not get scheduled to run on the physical CPU. High CPU ready % can lead to VM performance problems, such as slow response time or application latency. To improve VM performance, the administrator should reduce the number of vCPUs assigned to VMs or reduce the number of VMs on the hosts, so that there is less contention for CPU resources.


Question 2

What requires iSCSI initiator configuration in the guest OS to use Volumes?



Answer : B

The only option that requires iSCSI initiator configuration in the guest OS to use Volumes is Microsoft Windows Failover Cluster.Volumes is an enterprise-class, software-defined block storage solution that exposes storage resources directly to virtualized guest operating systems or physical hosts using the iSCSI protocol7. To use Volumes, customers need to configure iSCSI initiators on their hosts or guest OSes. However, some applications or services can use native storage adapters instead of iSCSI initiators when running on AHV VMs. These include:

SQL Server Always On Availability Group: This is a high availability and disaster recovery solution for SQL Server databases that uses Windows Server Failover Clustering (WSFC) and Availability Groups (AGs) as its core components. When running on AHV VMs, SQL Server Always On Availability Group can use native storage adapters instead of iSCSI initiators.

Oracle RAC: This is a clustered database system that provides high availability and scalability for Oracle databases. When running on AHV VMs, Oracle RAC can use native storage adapters instead of iSCSI initiators.

Exchange DAG: This is a group of up to 16 mailbox servers that hosts a set of databases and provides automatic database-level recovery from failures that affect individual servers or databases. When running on AHV VMs, Exchange DAG can use native storage adapters instead of iSCSI initiators.


Question 3

How many Prism Central instances are required to deploy Leap:'



Answer : B

The number of Prism Central instances required to deploy Leap is one per customer environment.Prism Central is a multi-cluster manager that provides a single, centralized management interface for Nutanix environments3.Leap is a native cloud extension that provides disaster recovery as a service (DRaaS) for Nutanix environments4.To use Leap, customers need to have one Prism Central instance deployed in their primary site, and register it with their Xi Cloud Services account5.This Prism Central instance can manage multiple Nutanix clusters across different physical sites or availability zones6.


Question 4

The customer is seeing high memory utilization on a mission critical VM. Users report that the application is unavailable. The guest OS does not support hot add components.

How should the administrator fix this issue?



Answer : B

The best way to fix this issue is to increase the amount of memory assigned to the VM from the Prism web console. This option allows the administrator to modify the VM configuration without accessing the CVM or shutting down the VM.The Prism web console provides a simple and intuitive interface for managing Nutanix clusters and VMs1.To change the memory allocation for a VM, the administrator can follow these steps2:

Go to the VM dashboard

Select the VM from the VMs list

Choose Update

Adjust the amount of memory assigned to the VM

Click Save


Question 5

An administrator is working with Nutanix Support and needs to provide logs for troubleshooting an issue. The cluster is located in a secure environment. Data such as IP addresses and VM names cannot be shared.

Which method should be used to anonymize the log data sent to Nutanix Support?

A)

B)

C)

D)



Answer : D


Question 6

Which algorithm do snapshots and clones leverage to maximize efficiency and effectiveness?



Answer : B

According to the Dell Unity: Data Reduction Technical White Paper1, snapshots and clones on Dell Unity use the Copy-on-Write (CoW) algorithm to maximize efficiency and effectiveness. CoW is a technique that defers the copying of data until it is modified. This means that snapshots and clones only consume space when changes are made to the source or the clone, respectively. CoW also preserves the original data in case of a rollback or recovery operation.


Question 7

How many SSL certificates are used by Prism Element on a Nutanix cluster?



Answer : A

According to the Nutanix Prism Element Guide, Prism Element uses a single SSL certificate on a Nutanix cluster. The certificate is used to secure the communication between the web browser and the Prism web console. The certificate is also used to authenticate the cluster to external services, such as Active Directory, SMTP, and SNMP. The certificate can be either self-signed or signed by a trusted certificate authority (CA). The certificate can be replaced or renewed through the Prism web console or the ncli command-line interface.
