Which of the following does the administrator use to consolidate all the VMs into a single IP while allowing access to the Internet?

DNS is used for name resolution and does not consolidate multiple IP addresses for Internet access.

A VLAN segments a network and groups virtual machines into a single logical broadcast domain, ensuring that all traffic from these VMs is directed through a common gateway. This grouping is an essential prerequisite step to allow the traffic from multiple VMs to be processed through a single routing or NAT device for consolidated outbound access to the Internet.

While NAT (Network Address Translation) directly performs the translation of multiple private IP addresses to a single public IP address for Internet access, the question emphasizes the consolidation of VMs within a network structure. A VLAN provides the foundational logical grouping that funnels traffic through a single point where NAT typically occurs.

DHCP assigns IP addresses to devices dynamically and does not consolidate multiple IPs for external access.
