Paper format. Professional Engineers of Ontario Annual Examinations, December 2014 — 07-Elec-B4 Information Technology Networks. Three hours, closed book, a PEO-approved non-programmable calculator permitted. Five questions of 25 marks each; any four constitute a complete paper worth 100 marks, with marks noted in the left margin. Candidates are urged to state any interpretive assumptions with their answers. All five questions are worked below, since the complete set is more useful as a study resource than any four of it.
