When looking for something completely different, I chanced across the following website. Whereas the information here is far more detailed than appropriate for a 30min question in the exam, I think it is an excellent source of informatiion for those wishing to tackle such questions that often come up in module 5 (and occasionally in module 7 or even module 1).

Looking at the contributors to a typical one (GW ATP) then it includes the names of two of those on the IRSE Exam committee......
Also if you navigate up a level from this page of Siganlling Risk Models, then there also other equivelent pages for Telecomms and other Elecctification & Plant to look at as well.
