The following is a question from a mock test: "What is an off-board server used for?" i) Delegating complex processing to a separate server ii) Enable secure remote access to a mainframe by forwarding SSL requests to serial connections. The correct answer is ii)
The only 'useful' description of an off-board server I have been able to find is the following (http://www.leocrawford.org.uk/work/jcea/part1/legacy.html): "An off-board server is a server that executes as a proxy for a legacy system. It communicates with the legacy system using the custorm protocols supported by the legacy system. It communicates with external applications using industry-standard protocols" Assuming the above description is correct, an off-board server sounds more like an adapter (rather than a proxy!), and it does not implies "SSL requests to serial connections", but any protocol that the legacy application uses. Therefore I think answer ii) is not correct.
Could anyone clarify what an off-board server is, and if possible provide a link with more information about off-board servers.
