A node with Erasure Coding fails.
What is the impact?
A. The node stops utilizing Erasure Coding.
B. Potentially increased amount of data stored in the SSD tier.
C. Increased Controller VM CPU Load.
D. AQS unable to do deduplication during the Erasure Coding failure.
Explanation: When a node with Erasure Coding fails, the cluster will automatically rebuild the missing data using replication factor (RF) 2 or 3, depending on the cluster configuration. This means that the data that was previously stored using Erasure Coding will now be stored using full copies, which may increase the amount of data stored in the SSD tier1.
An administrator notices that most of the VMs in the cluster are on one host. Users report that an application seems to respond slowly. The application server VM has significantly more memory assigned to it than other VMs.
How should the administrator fix this issue?
A. Reduce the amount of memory assigned to the VM.
B. Migrate the VM to a different host.
C. Add more memory to the VM.
D. Increase the memory on the CVM.
Explanation: According to the Troubleshoot high memory issues on Azure virtual machines web search result2, one of the common factors in a low memory situation is over-provisioning memory for a VM. Over-provisioning memory can cause memory pressure, which leads to swapping and degraded performance. Therefore, to fix this issue, the administrator should reduce the amount of memory assigned to the VM, based on the average hardware requirements for that operating system and application load.
What is the default network bond setting for an AHV host configuration?
A. active-backup
B. active-active
C. balance-slb
D. balance-tcp
What is the expected operation during node addition when the new node has a different AOS version?
A. The entire cluster is upgraded to the latest one-click release.
B. The node is added and a separate upgrade operation must be performed.
C. The addition fails and forces the administrator to image using standalone Foundation.
D. The node is automatically re-imaged using the software currently running in the cluster.
Explanation: The node is automatically re-imaged using the software currently running in the cluster. This is because Nutanix supports a feature called Auto Re-Image that allows adding nodes with different AOS versions to an existing cluster without manual intervention. The Auto Re-Image feature detects the AOS version mismatch and automatically downloads and installs the same AOS version as the cluster on the new node. This ensures that the cluster remains in a consistent state and avoids any compatibility issues.
An administrator needs to relocate an AHV cluster to a new datacenter during a maintenance window. The cluster will use the same IPs in the new datacenter.
Which two steps should be taken to prepare for this task? (Choose two.)
A. Reconfigure IPMI for the new datacenter
B. Shut down all user VMs in the cluster
C. Relocate the linked LDAP server
D. Stop all Nutanix Files clusters
Explanation:
According to the web search results, two steps that should be taken to prepare for relocating an AHV cluster to a new datacenter during a maintenance window are:
Shut down all user VMs in the cluster: This step is necessary to ensure that there is no data loss or corruption during the relocation process. The user VMs can be shut down either individually or in bulk by using the Prism Element web console or the acli command-line interface1.
Stop all Nutanix Files clusters: If the AHV cluster hosts any Nutanix Files clusters, they should be stopped before relocating the cluster. Nutanix Files clusters are composed of one or more virtual machines that provide file services to clients. Stopping a Nutanix Files cluster will stop all the file server VMs and release the resources they consume2. The Nutanix Files clusters can be stopped by using the Prism Element web console or the ncli command-line interface3.
