H31-321 (HCIP-Optical Solution Architect): the official syllabus with its topic weights, the real exam facts, and 5 free sample questions answered in full — pseudowire emulation, Raman tilt across C and L bands, the transmit chain at a terminal site, an ODN link budget, and GPON/XGS-PON coexistence.

Everything here comes from the published HCIP-Optical Solution Architect syllabus and CertFun's free sample questions — no dumps, no "real exam" claims. The exam facts are read straight off the syllabus page, and the questions and answer key are CertFun's own free samples. The reasoning after each answer is ours.

Twelve topics, none weighted above 10%, which tells you what this exam is: broad rather than deep. It moves between DWDM line systems, SDH protection, PON and ODN planning, and you are expected to be fluent in all of them. The five questions here are spread across that range on purpose, and one of them is pure arithmetic you have to get exactly right.

Question 1 is a multi-select — it asks for two of five.

Question 4 at 4:00 is the one to pause on — a branch that closed its budget with 4.2 dB of margin, then a diversion adding route length, four fusion splices and two connector pairs. Work out the added loss before you look at the options; two of them are built on plausible-sounding rules that do not exist. Tell me in the comments what you got.
