A customer wants to isolate a group of VMs within their Nutanix environment for security reasons. The customer creates a VM with two NICs to act as a firewall and installs the appropriate software and certificates. However, no one from the outside can access the application.
What is the likely cause of this problem?
The issue is likely because one of the NICs needs to be configured on the internal VLAN. In such a setup, to properly direct traffic both internally and externally, it is essential that one NIC connects the VM to the internal VLAN while the second NIC ensures communication with the external network. Without proper VLAN configuration, the firewall VM cannot manage traffic flow effectively, resulting in no external access to the application.
C is correct. A. A shared volume group must be used by all isolated VMs Volume groups have no relation or impact on NW B. More than one NIC cannot be added to a VM NICs are limited to: the 32 virtual PCI addresses of the VM (also populated by other PCI devices), or whatever limit the OS has within that VM (fe: Windows 2016 supports a maximum of 12) https://next.nutanix.com/installation-configuration-23/limit-or-maximum-nics-on-vm-38066 C. One of the NICs needs to be configured on the internal VLAN Obvious, and the correct answer. D. Wireshark is installed on the NAT VM Wireshark is a passive network analysis tool, which means it does not interfere with the network at all - unless, of course, you use network name resolution, which leads to DNS reverse pointer queries. https://osqa-ask.wireshark.org/questions/15901/capturing-udp-packets-affects-network-performance#:~:text=No.,to%20DNS%20reverse%20pointer%20queries.
