What method should an administrator use to isolate a VM from the production network while still allowing diagnostic access?

The correct method for isolating a virtual machine (VM) from the production network while still allowing for diagnostic access involves using the Forensic Method to quarantine the VM. This approach allows the VM to be effectively disconnected from the production network, preventing any potential interference or security risks to the live environment. Simultaneously, this method facilitates a controlled environment where the administrator can still perform diagnostic checks or analyses on the VM.

Quarantining a VM through the Forensic Method ensures that all traffic originating from or destined to the VM can be monitored and analyzed for troubleshooting or security assessment purposes without impacting the operational integrity of the production network. It provides a secure and segregated environment for diagnostics, which is essential in maintaining the overall health and security posture of the wider network.

The other methods, while they may offer partial solutions, do not provide the same level of isolation combined with diagnostic access. Disabling the vNIC would completely prevent any form of communication, including diagnostic access, which is counterproductive. Creating a firewall rule that blocks VM traffic but allows diagnostic access could be complex and less reliable, as it may be difficult to ensure that all necessary diagnostic communications are preserved. Establishing a security policy with a service chain directing VM traffic to the firewall may introduce unnecessary
