Final answer:
To isolate a network of servers so that they cannot interact with other servers, a VLAN (Virtual Local Area Network) is the appropriate technology. It partitions a physical network into multiple virtual ones, preventing communication between different VLANs without configured routing.
Step-by-step explanation:
The technology that you can use to isolate a network of servers so that they cannot interact with other servers is a VLAN (Virtual Local Area Network). A VLAN allows network administrators to partition a single physical network into multiple virtual networks. This means that servers or devices on different VLANs would be unable to communicate with each other without proper routing configured to allow for such communication.
This is different from a bridge switch or router none of which alone can provide the level of network isolation between servers that is achieved through the use of VLANs.
