In the scenario where a consultant is viewing an ESXi host via console without external network connectivity and needs to connect to the Controller Virtual Machine (CVM), the typical IP addresses used for such connections in a Nutanix environment are in the 192.168.5.x range. Specifically, the IP addresses for CVMs often set by default or during initial configuration, such as 192.168.5.253 and 192.168.5.254 (Options A and C), can be used. These addresses are generally reserved for internal CVM communications and can be accessed through the host's internal network configurations.References: Nutanix Cluster Installation Guide, Default Nutanix Network Configurations.

Explanation

In a Nutanix Files deployment within a 20-node AHV cluster, the consultant can deploy a maximum of 16 FSVMs (File Server Virtual Machines). This limitation is based on Nutanix's best practices and design considerations for scalability and performance. The number of FSVMs that can be effectively managed and maintained without degrading the performance of the file-serving operations or the underlying storage infrastructure dictates this maximum.
