To revert both clusters to their original state after testing DR by activating VMs on the remote cluster, the administrator needs to ensure that replications are suspended to prevent any further changes during the process. The steps include suspending the replications on the primary site to prevent any conflicts or data loss (Step 1), deactivating the Protection Domain on the remote site using ncli to stop the DR environment (Step 2), and then migrating the protection domain back to the primary site (Step 3). This sequence ensures that both clusters return to their original states with minimal disruption.References: Nutanix Disaster Recovery Guide, Nutanix Administration Guide.

The As-Built Guide is a comprehensive document typically prepared at the end of a Nutanix deployment project. It includes detailed information about the Nutanix environment, such as IP addresses, storage container settings, hardware and software configurations, and other deployment specifics. This document serves as a reference for the customer to understand their deployed infrastructure and for any future modifications or troubleshooting needs.

For a Nutanix cluster to support Replication Factor 3 (RF3), a minimum of 5 nodes is required. RF3 means that three copies of the data are maintained across the cluster for fault tolerance and high availability. Having at least five nodes ensures that there are sufficient nodes to distribute these copies across different fault domains, minimizing the risk of data loss and providing improved resilience against node failures.References: Nutanix Bible, Nutanix Technical Documentation on Data Resiliency.

In the scenario where SQL queries are running slower post-migration, creating multiple TempDB data files is a recognized best practice for optimizing SQL Server performance, especially when dealing with high transaction rates or complex queries. This approach helps in distributing the I/O load across multiple files and drives, reducing the contention and wait times associated with TempDB, which is a common bottleneck in SQL Server environments. Enabling autogrowth ensures that these files can dynamically grow as needed, which helps in handling unexpected increases in database activity without manual intervention.References: Nutanix Best Practices for SQL Server, SQL Server performance tuning guidelines.

If a customer needs to re-image an existing cluster and both the Foundation Applet and Foundation VM are unavailable, the consultant can access Foundation-as-a-Service (FaaS) through the CVM IP address followed by port 9443, as indicated in Option C. FaaS allows for the re-imaging of Nutanix nodes through a web interface hosted directly on the CVM, making it an effective tool for deploying and managing clusters without needing additional installation media or virtual machines.References: Nutanix Foundation as a Service (FaaS) Documentation, Nutanix Support Portal.

In the scenario where the Foundation VM on a laptop is used for a cluster deployment, and an error indicating a failure to connect to the IPMIs is shown, the first troubleshooting step should be to disable the local machine's firewall to ensure it is not blocking traffic necessary for the Foundation VM to communicate with the IPMIs. Firewalls can often block essential ports or IP addresses needed for deployment operations, hindering the Foundation process.References: Nutanix Foundation Tool Troubleshooting Guide, Nutanix Deployment Common Issues.
