Nutanix NCS-Core Dumps Questions Answers

The manage_ovs command requires specific interface names to be added or configured under a bridge or bond. In the provided scenario, the command failed because it generically referred to '1g' which is not a recognized interface or valid parameter syntax. For the command to work correctly, each individual interface name must be specified. In this case, the missing parameter was the specific interface name 'eth0' for one of the 1GbE NICs. The corrected command should explicitly include the NIC names, e.g., --interfaces eth0,eth1.References:

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

Upon reviewing the network configuration in the provided image and considering the setup in a Nutanix environment, the best action to improve network performance is to adjust the bonding mode for the bridge that includes multiple high-bandwidth interfaces.

Option C, "Configure balance-sib or balance-tcp mode for br0-up if switch configuration allows," is the most effective choice. The bonding mode "balance-sib" (source IP-based load balancing) or "balance-tcp" (TCP/IP layer balancing) can optimize the distribution of network traffic across multiple interfaces, thereby enhancing throughput and redundancy.

This approach utilizes the capabilities of multiple network interfaces more efficiently, distributing the load to prevent any one interface from becoming a bottleneck while providing failover redundancy.

References:This configuration strategy aligns with best practices for network setup in high-performance virtualized environments, as detailed in Nutanix’s networking configuration guides and the Nutanix Bible, ensuring optimal performance and reliability.
