When updating the LCM Framework on a dark site web server, the LCM Framework Bundle should be extracted to the "release" directory. This directory is specifically designated for holding the updated LCM Framework files, and the update process will look for the files in this location. Extracting the bundle to a different directory, such as "upgrade", "software" or "install" would not be sufficient as the LCM Framework update process may not be able to find the files.

Erasure coding is a data efficiency mechanism in Nutanix that replaces the traditional replication factor for suitable data. Erasure coding uses a technique known as "forward error correction" to spread data across multiple drives in a cluster, such that if some drives fail, the data can still be reconstructed. This allows for a much higher storage density and a more efficient use of disk space as compared to traditional replication, where multiple copies of the same data are stored across multiple drives. Deduplication and Compression are also data efficiency mechanisms in Nutanix which help to reduce the storage overhead by eliminating the redundant data. Intelligent Cloning is a Nutanix feature which helps to create multiple instant, space-efficient clones of a VM. Reference:

In a Nutanix AHV-based cluster, if a node fails, the cluster will automatically take actions to ensure high availability of the virtual machines. The cluster will automatically live migrate the VMs running on the failed node to other healthy nodes in the cluster without any user impact, this process is known as "Failover" . The live migration process ensures that the VMs are restarted on another node in the cluster as soon as possible with minimal interruption to the users. The cluster

CPU and memory utilization being around 50% at the time of failure does not affect the failover process.

To send weekly performance reviews to several line of business managers about VMs they are managing, the administrator should use Prism Central Reports with a schedule. Prism Central Reports is a tool that allows the administrator to create custom reports, which can include information such as CPU usage, memory usage, and disk I/O for specific VMs. The administrator can schedule the reports to be generated and sent out on a regular basis, such as weekly. This will allow the line of business managers to review the performance of the VMs they are responsible for on a regular basis, and take appropriate actions if necessary. Reference:

Deduplication is a storage efficiency feature in Nutanix that is suitable for nearly every workload.

Deduplication is a technique that eliminates redundant data and reduces the amount of storage space required to hold that data. This can help to significantly reduce the storage overhead, and improve the overall storage efficiency of the cluster. Deduplication can be applied to all types of data, including virtual machine disks, and can help to reduce storage costs by reducing the amount of physical storage required. Reference:

Link Aggregation Control Protocol (LACP) is a NIC-teaming configuration that balances network traffic based on source/destination IP addresses and TCP/UDP ports. LACP allows the administrator to configure multiple NICs as a single logical NIC, known as a Link Aggregation Group (LAG), which can increase the available bandwidth and provide redundancy. LACP uses a hashing algorithm to distribute traffic across the NICs in the LAG, based on the source and destination IP addresses and TCP/UDP ports. This ensures that traffic is evenly distributed across the NICs, which helps to improve overall network performance and availability. Reference:

In Nutanix, a virtual disk (vDisk) is a file that is stored on storage devices owned by a CVM (Controller Virtual Machine). A vDisk is a virtual representation of a physical disk and it is used to store the data of a virtual machine. Each virtual machine has one or more vDisks associated with it, and these vDisks can be stored on different types of storage media, such as solid-state drives (SSDs) and hard disk drives (HDDs). The vDisks are stored in a container that is managed by the CVM, and it is the basic building block for storing virtual machine data on the Nutanix cluster. Storage Pool, Extent Group, and Container are all related concepts but different entities in Nutanix. A storage pool is a collection of physical storage devices that are used to store virtual machine data. An extent group is a collection of storage extents that are used to store virtual machine data. A container is a logical grouping of virtual machines, virtual disks, and other objects in Nutanix. Reference:

When upgrading AOS in a vSphere-based Nutanix cluster with no automatic live migration, the VMs will continue to run on the same host, providing that the VMs have neither affinity nor anti-affinity rules configured. The upgrade process will put the host into maintenance mode, which will cause the VMs running on that host to be suspended temporarily. Once the AOS upgrade is completed, the host will be taken out of maintenance mode, and the VMs will be resumed, but running on the same host.

The AOS upgrade process does not automatically live migrate VMs to other hosts, because the automatic live migration feature is not enabled in the cluster. Reference:

In order to resolve the issue of not receiving NCC health checks and alerts for newly-added nodes via email, the administrator should configure SMTP (Simple Mail Transfer Protocol) settings. SMTP is used to send email notifications from the Nutanix cluster, and if it is not configured properly, the health checks and alerts will not be sent via email. The administrator should check the SMTP settings in the Prism web console and ensure that they are correct and that the correct email address is specified for receiving notifications. This will ensure that the health checks and alerts for the newlyadded nodes are sent to the correct recipient.
