In which two scenarios is an automated live migration likely to occur? (Choose two)
A. Cluster resource hotspot
B. AOS upgrade
C. Network upgrade
D. Hypervisor upgrade
Explanation:
Automated live migration is a feature of Nutanix that allows the cluster to automatically move VMs from one host to another without any downtime, in order to optimize the performance and availability of the cluster. According to the Nutanix documentation1, automated live migration can occur in the following scenarios:
Cluster resource hotspot: When a host or a group of hosts experience high resource utilization, such as CPU, memory, or network, the cluster can automatically migrate some VMs to other hosts with lower utilization, in order to balance the load and avoid performance degradation.
AOS upgrade: When upgrading the Nutanix software (AOS), the cluster can automatically migrate the VMs from the host that is being upgraded to another host in the same availability zone, in order to maintain the VM availability and minimize the impact of the upgrade process.
AHV host maintenance mode: When putting an AHV host into maintenance mode, the cluster can automatically migrate all the VMs from that host to another host in the same availability zone, in order to prepare the host for maintenance operations such as hardware replacement or firmware update.
A recently configured cluster is leveraging NearSync with a recovery schedule of 15 minutes. It is noticed that the cluster is consistently transitioning in an Out of NearSyne.
What action should be taken to potentially address this issue?
A. Increase network bandwidth
B. Change the NearSync schedule to 30 minutes.
C. Add a vCPUs to the user VMs.
D. Configure a secondary schedule in the same Protection Domain.
Explanation:
One of the possible reasons for a cluster to transition out of NearSync is insufficient network bandwidth between the source and target clusters. NearSync requires a minimum network bandwidth of 10 Mbps per VM for replication3. If the network bandwidth is lower than the required amount, the replication of recovery points may take longer than the configured RPO, resulting in an Out of NearSync condition. To address this issue, you can increase the network bandwidth between the clusters or reduce the number of VMs protected by NearSync4.

An administrator needs to periodically send information about cluster efficiency via email to a set of users.
What should be configured to accomplish this task?
A. Configure Efficiency widget in Prism Central.
B. Create a new' prism Central project.
C. update Capacity Configurations in Prism Central.
D. Add a schedule to Prism Central reports.
Explanation:
To periodically send information about cluster efficiency via email to a set of users, the administrator can follow these steps:
Create a report in Prism Central that contains the relevant information about cluster efficiency.
Add a schedule to the report to generate and send the report via email to the set of users at a specified frequency.
This will ensure that the users receive regular updates about the cluster efficiency without the need for manual intervention.
How should an administrator correct an SSL error when connecting to a Nutanix cluster?
A. Add the SSL certificate to the workstation’s trusted people store
B. Create a new self-signed certificate for the cluster with a 4096 bit key
C. Create a new SSL certificate for the cluster signed by an AD certificate authority
D. Add the SSL certificate to an AD group policy applied to all computer objects
After configuring Active Directory as the desired authentication service, an administrator is not able to login into Prism Central using privileged account.
Which configuration must be checked first?
A. Account lock status
B. Role Mapping
C. Local user account
D. Cluster Lockdown
Explanation: According to the Nutanix Community1, users can authenticate using their Active Directory credentials when Active Directory support is enabled for Prism Central. To enable Active Directory support, you need to configure Role Mapping12, which defines how Active Directory groups map to Prism Central roles.
