To increase the Redundancy Factor (RF) from 2 to 3, at least five nodes are required for the cluster to function correctly with RF3, as each data block needs to be replicated to three different nodes. However, the optimal solution that offers both the necessary node count and sufficient storage overhead is:

• Six Compute Nodes with 25% available disk space: This configuration ensures that there are enough nodes to support RF3 while maintaining adequate storage capacity for redundancy without overutilization.

For licensing reasons and to ensure compliance with software license terms, particularly for databases like SQL and Oracle RAC, VM-Host affinity policies are used. These policies help in pinning VMs to specific hosts. In this scenario, SQL Servers must be confined to specific hosts to manage licensing costs effectively, and similarly, Oracle RAC servers must be on separate hosts. The VM-Host affinity policy allows for such configuration by defining rules that keep VMs on specific hosts or separate them as needed.References:

Noticing a potential typo or error in the DNS server IP address notation:

• D. New IPs provided should be verified to not conflict with the customer's network: It's crucial to verify the accuracy and validity of the IP addresses provided, ensuring there are no typos and that the IPs do not conflict with existing network configurations. The noted IP '192.1685.20' appears to be incorrectly formatted and should be corrected and validated.
