Paper format. Professional Engineers of Ontario, Annual Examinations — May 2016, 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, and the marks are printed in the left margin against every sub-part. All five questions are solved here, because this set is a study resource rather than an exam attempt.
