Nutanix Updated NCS-Core Exam Questions and Answers by elin

When using the Nutanix cluster As Built Document generator, the necessary configuration elements to provide when running the run_as_built.exe command include the Cluster IP (B) and the Customer Name (D). The Cluster IP is required to properly identify and communicate with the cluster to gather configuration and operational data. The Customer Name is typically used to personalize the documentation, making it specific to the client's deployment, which is useful for record-keeping and future reference purposes.References: Nutanix As Built Documentation generator usage guidelines, Nutanix Best Practices for Documentation.

When Foundation reports an error indicating the ISO is not supported:

• Option B: Checking the MD5 checksum of the ISO file ensures that it matches the expected value listed by Nutanix, confirming the file's integrity and compatibility.
• Option D: Downloading and updating the iso whitelist.json from the Nutanix Support Portal ensures that Foundation has the latest information on supported ISO files, potentially resolving compatibility issues.

For a configuration that aims to utilize all available 10G links, achieve maximum throughput per VM, and ensure redundancy with fast reconvergence during link failure, the optimal setting would be to configure Balance-TCP on bridge br0. This setting distributes the load across all available network paths based on the TCP session, maximizing the utilization of network interfaces and ensuring redundancy. This approach is particularly effective in environments with multiple network paths and ensures efficient network traffic management.References:

When preparing the cluster offsite in a safe room, the consultant should ensure that the Foundation VM is correctly configured to handle IPMI networking. Implementing a virtual switch dedicated to the IPMI network within the Foundation VM environment ensures that there is a segregated and controlled network path for IPMI traffic, which is crucial for initial hardware configuration and management. This setup facilitates the secure and efficient foundation process before the cluster is moved to the data center.References: Nutanix Foundation Tool Guide, Nutanix Network Configuration Best Practices.
