In preparing to install a new cluster for a company, a consultant needs to complete an installation worksheet.
Which values must be documented prior to initial base system setup?
A. Block Serial Numbers
B. Hypervisor, CVM, and IPMI IP Addresses
C. DNS and NTP IP Addresses
D. Prism Central IP Address
Explanation: Prior to the initial base system setup for a new cluster installation, the consultant needs to document several critical infrastructure details. Among the most important are the DNS and NTP IP addresses (C). These addresses are crucial because they ensure that all nodes within the cluster can resolve domain names properly and synchronize their clocks accurately, which is vital for cluster operations and management. Proper DNS and NTP configurations help prevent many common issues related to name resolution and time synchronization that could affect the performance and stability of the cluster.References: Nutanix Installation Prep Guide, Nutanix Network Configuration Requirements.
An administrator needs to make sure an RF3 cluster can survive a failure of two complete racks without negatively affecting performance. The current cluster configuration consists of the following:
• 30 All Flash Nodes: distributed 10 nodes per rack across three 42U racks
• Each node is configured with 20TB usable storage all flash (Cluster Total 600TB Usable)
• Current cluster utilization is 500TB storage
• Storage containers have Erasure Coding enabled
Which configuration changes should be made to make sure the cluster meets the requirements?
A. Expand the cluster to 50 nodes distributed evenly across 5 racks
B. Expand the cluster to 48 nodes distributed evenly across 6 racks
C. Expand the cluster to 60 nodes distributed evenly across 6 racks
D. Expand the cluster to 40 nodes distributed evenly across 5 racks
A consultant will be doing an install for an enterprise customer. The consultant has racked up, powered on, and connected their Foundation software to the new nodes. The Foundation VM is not discovering the hardware.
What should the consultant do to resolve this issue?
A. Console to each node, reboot the node, go through BIOS to set an IPMI IP address, then run Foundation bare metal installation using IPMI IP addresses.
B. Connect a crash cart to each node, log in to the pre-installed AHV hypervisor, run the IPMITool commands to set IPMI IP Address, subnet, and gateway for each node. Run a Foundation using the configured IPMI addresses that were just set.
C. Collect the IPMI MAC addresses on the back of each node, run a bare metal Foundation using each MAC addresses.
D. Connect a crash cart to each node, reboot the node, go through BIOS and set an IPMI IP address for each node. Using your Foundation VM, create a Phoenix boot ISO, then mount the ISO via Virtual Media connector from IPMI.
Explanation:
In a Nutanix environment, if the Foundation VM is not discovering the hardware, it could be due to issues with the IPMI (Intelligent Platform Management Interface) settings. IPMI is a set of computer interface specifications for an autonomous computer subsystem that provides management and monitoring capabilities independently of the host system’s CPU, firmware (BIOS or UEFI), and operating system.
In this scenario, the consultant should connect a crash cart to each node, log in to the pre-installed AHV hypervisor, and run the IPMITool commands to set the IPMI IP Address, subnet, and gateway for each node. After setting the IPMI settings, the consultant should run Foundation using the configured IPMI addresses that were just set.
This will ensure that the Foundation VM can communicate with the nodes via IPMI and discover the hardware, allowing the installation to proceed.
An administrator needs to configure snapshots for DR scenarios. The databases get refreshed on Friday nights regularly. The search service application re-indexes the new application on Saturday nights regularly. The remaining front-end and middle tier VMs are static but do get minor version updates weekly.
The administrator needs to have 2 weeks of daily snapshots for all the VMs in an app group and 2 weeks application consist local snapshots only on Fridays, Saturdays and Sundays on the same group of VMs.
Which two options should the administrator use to configure snapshots?
A. Create a schedule in a protection domain for all applicable VMs to snap daily with application consistency enabled with 6 days of retention and with no application consistency and 14 days local retention.
B. Create two consistency groups in a protection domain, one for front-end and middle tier apps with no application consistency, one for database and Search apps with application consistency, and apply the correct schedule to both groups.
C. Create one protection domain for all VMs in an application group with scheduled daily non-application consistent snapshots and another protection domain for all VMs in an application group with scheduled Friday. Saturday, Sunday application consistent snapshots.
D. Create a protection domain for all VMs
A consultant is deploying a two-node cluster at a remote branch office.
Which component must be available to complete cluster configuration?
A. Prism Central
B. Witness VM
C. Remote Site
D. Protection Domain
Explanation: In the deployment of a two-node cluster at a remote branch office, the presence of a Witness VM is essential to manage the cluster quorum and data integrity in case one of the nodes fails or becomes unreachable. The Witness VM acts as an external arbitrator that helps prevent data unavailability and split-brain scenarios in a situation where the cluster nodes cannot communicate with each other. This configuration is necessary because with only two nodes, there isn't a third node to maintain quorum natively. References: Nutanix Bible, Nutanix University
