An alert about RX errors on eth2 on a node is reported in the cluster. The administrator logs in to the CVM in question, checks the ping_* files in the data/logs/syststats folder, and notices intermittent ping loss.
The node in question has the following network configuration:
Which action should be used to troubleshoot without disrupting the VMs running on this node?
Explanation:
Given the reported RX errors on eth2 and the intermittent ping loss as observed from the CVM logs, the best initial troubleshooting step that avoids VM disruption is to inspect the switch port for errors. Option C, 'Check the port on the switch side for any errors,' is the most direct and non-invasive approach to determining if the issue lies with the network infrastructure rather than the server hardware itself or the configuration.
This action helps identify whether the problem is related to the physical connection (e.g., port issues, switch configuration errors) without altering the current active network setup on the Nutanix node. If errors are found on the switch port, adjustments or repairs can be made accordingly, potentially resolving the RX errors without impacting the running VMs.
Reference: This recommendation follows Nutanix's best practices for network troubleshooting, focusing first on external network components before altering host configurations.

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?

An administrator is monitoring the Nutanix v5.15-based AOS cluster performance logs and notices that a SQL server VM is greatly exceeding its intended maximum IOPS. The administrator has confirmed that a QoS policy was previously created for the group of VMs this server is a member of.
What are two reasons that this VM would exceed its maximum configured IOPS from the QoS Policy? (Choose two.)

An administrator protected a DB VM running on a Nutanix cluster with NearSync Replication, which schedules to repeat every 15 minutes to a second site. The daily change rate is low. During nightly backups, the replication window is missed due to write volume.
Which two options describe the expected behavior? (Choose two.)
Explanation:
When a NearSync Replication window is missed due to high write volume during nightly backups, the expected behavior of the system is to adjust the replication schedule temporarily and continuously attempt to return to the configured NearSync schedule. The correct answers are:
Option B, 'Protection Domain transitions back to the hourly schedule.' If the NearSync cannot maintain the 15-minute schedule due to excessive write volume, it may temporarily fall back to a less frequent schedule, such as hourly, to stabilize.
Option D, 'The system continuously tries to get to the NearSync schedule.' NearSync is designed to handle transient high-load situations by trying to catch up and revert to the pre-set NearSync schedule as conditions allow.
Reference: These behaviors are outlined in the Nutanix documentation for NearSync, which describes how the system manages periods of high I/O and missed replication windows.
An administrator needs to forecast infrastructure requirements for a new program and its associated applications. Prior to the projected start of the new program, all existing applications will be decommissioned.
How should the administrator perform this task?
Explanation:
When forecasting infrastructure requirements for a new program in a Nutanix environment where all existing applications will be decommissioned, the most straightforward method is to disregard any workload calculations that include existing applications. This ensures that the analysis focuses solely on the needs of the new program.
Option A, 'Check the Disregard Existing Workloads radio button in the Runway scenario,' is the correct choice. Nutanix Runway is a tool designed to help administrators forecast and plan infrastructure requirements based on upcoming needs without being skewed by current utilizations that are scheduled to be decommissioned.
This method allows for a cleaner, more accurate projection of resources needed for the new applications, disregarding any resources currently in use that will no longer be relevant.
Reference: This approach is detailed in Nutanix planning and forecasting documentation, ensuring administrators can plan accurately for infrastructure changes and needs without the interference of outgoing workloads.
A CEO asks the IT administrator to provide a list of required resources to protect current workloads and the two new SQL servers from a disaster. The Nutanix environment is managed by Prism Central.
Which option explains how to meet the CEO's request?
Explanation:
In a Nutanix environment managed by Prism Central, protecting workloads and SQL servers from a disaster involves creating a recovery policy. A recovery policy in Nutanix is a set of rules that define how data is protected and recovered in the event of a disaster1.
Creating a new recovery policy involves selecting the virtual machines (VMs) that need to be protected and specifying the hardware requirements for the recovery environment1. This includes the compute and storage resources needed to run the protected VMs in the recovery site1.
Once the recovery policy is created, Nutanix's built-in data protection and disaster recovery capabilities can ensure that the protected VMs can be quickly and efficiently recovered in the event of a disaster2. This includes capabilities such as efficient snapshot, cloning, and replication capabilities to provide a higher level of protection at a lower cost2.
Therefore, to meet the CEO's request, the IT administrator should create a new Recovery policy by selecting the VM that needs to be protected and get hardware requirements.
