NCS-Core Exam Dumps : Nutanix Certified Services Core Infrastructure Professional (NCS-Core 6.8)

When nodes are mistakenly configured with incorrect IP addresses and are on a different network, the most effective way to address this is to re-run the Foundation process. By using Foundation, the nodes can be completely re-imaged with the correct network settings and then properly integrated into a new cluster. This ensures that all hardware and software configurations align with the intended network and cluster settings, avoiding potential conflicts and issues that might arise from manual adjustments.

In the As-Built Guide for an AHV cluster deployment with each node configured with four NICs, the consultant should manually update:

• A. Node Port Layout Diagram: To reflect the physical connectivity and usage of each NIC on the nodes.
• B. Network Cabling Diagram: To accurately document how each node is connected to the network infrastructure, ensuring clarity on physical network setup.

To satisfy the customer's requirements for maximum uptime and throughput in an AHV cluster deployment with link aggregation at the Top-of-Rack (TOR) switches, the consultant should:

• Bonded 2 x 40GbE Adapters with LACP Enabled for Storage Traffic and Guest Traffic using balance-tcp: This configuration leverages Link Aggregation Control Protocol (LACP) to combine the bandwidth of the two 40GbE adapters, enhancing both redundancy and throughput. The balance-tcp mode ensures effective load balancing of traffic based on TCP session ensuring optimal use of available bandwidth and improved fault tolerance.
