Nutanix NCS-Core Exam With Confidence Using Practice Dumps

To separate management and production traffic within a Nutanix AHV cluster, VLAN Tagging is the appropriate feature to configure. VLAN Tagging allows different types of traffic to be segregated onto different network segments over the same physical infrastructure, effectively isolating management traffic from production traffic at the network level. This setup enhances security and performance by reducing the possibility of network congestion affecting critical management operations.

To ensure additional resiliency in a 20-node ESXi deployment capable of surviving the concurrent loss of two nodes, the consultant should configure the system with a storage reservation and HA (High Availability) admission control each set to 5%, combined with a cluster redundancy factor (RF) of 3. RF3 provides the capability to tolerate the failure of up to two nodes without data loss, thus enhancing the cluster's resilience. This configuration is optimal for maintaining cluster availability and integrity during multiple node failures.References: Nutanix Bible, Nutanix University

To manually create a cluster after the nodes have been successfully imaged but the automated cluster creation fails, the correct command to use is:

cluster create -s IP_CVM_A, IP_CVM_B, IP_CVM_n

This command specifies the -s option to include the IP addresses of the Controller Virtual Machines (CVMs) on the nodes, initiating the manual cluster creation process.
