In the event of an Active Directory outage that prevents login to Prism, the recommended approach is to have a contingency plan that allows for local management of the cluster. Option B, "Create and use an emergency local account on the cluster," is the correct choice. This approach ensures that administrators can still access and manage the cluster even if external authentication services are down.

An emergency local account provides a direct, reliable means to access Prism and perform necessary administrative tasks without depending on external systems. This is a critical backup strategy for maintaining access control and managing the cluster during outages.

References:This method is in line with best practices for system availability and disaster recovery, ensuring administrators retain access to manage and troubleshoot without interruption, as detailed in Nutanix's documentation and security configuration guidelines.

When addressing high cluster IOPS and Cluster Controller Latency where networking is suspected to be the issue, it is essential to check the network configuration settings that can directly impact data transfer and latency. The correct answer is to adjust the "Number of NICs connected" and "frame size." Increasing the number of Network Interface Cards (NICs) connected can improve the network throughput and distribute the load more evenly. Adjusting the frame size, particularly setting larger frames (Jumbo Frames), can reduce overhead and improve network efficiency by allowing more data to be transmitted with fewer packets.

To meet the requirement of having two weeks of daily snapshots and application-consistent snapshots on specific days (Friday, Saturday, Sunday), the best approach is to use two separate protection domains. This setup allows for greater flexibility in managing retention policies and ensuring application consistency. One protection domain will handle daily snapshots without application consistency for regular backups, and the other will handle application-consistent snapshots for critical times when databases and applications are updated, ensuring data integrity during these operations.

The scope of services for the deployment of a new Nutanix cluster would apply to both Foundation and Prism Central. Foundation is the initial software used for deploying Nutanix nodes and creating clusters, essential for setting up the environment. Prism Central is used for managing multiple clusters and is integral to the operational scope of the service, providing centralized management capabilities.References: Nutanix Bible, Nutanix University NCS-Core 6.8 learning materials

In this scenario, the delay and packet loss during failover when one of the network cables is disconnected can be addressed by enabling "Portfast" on the switch ports connected to the Nutanix nodes. Portfast is a Cisco network switch feature that allows network switches to immediately bring ports into the forwarding state during connectivity changes, bypassing the usual listening and learning states of Spanning Tree Protocol (STP). This significantly reduces the time to re-establish network connectivity, thereby minimizing the packet loss during such failover events. Enabling Portfast is crucial for endpoints like servers where quick recovery from disconnections is necessary.References: Cisco Networking Academy materials on STP and Portfast, Nutanix Bible.
