NCTI ROC II BOOK II FINAL Test 1 When pressure testing a drop system to check for leakage, What must be done before applying the test signal? - ANSWER The technician must isolate the drop system from the hybrid fiber/coax (HFC) network by disconnecting the drop at the distribution tap. Why do some leakage detection systems utilize a leakage carrier modulated with a tagging signal? - ANSWER To avoid false detection of l...

A1) Benefits of pentesting - Manage risk. Increase business continuity. Minimise client-side attacks. Protect clients, partners and third-parties. Comply with regulation. A1) Pentest structure - Reconnaissance (i.e. find live hosts, sweeping, find services, scanning, banner matching, find vulnerabilities). Target prioritisation (e.g. assess servers rather than printers). Testing of services and exploitation if applicable. Consult/Confirm with customer if ok to exploit. Inform customer of any ...

What is a linear measure of optical power? correct answer: Watts What is the measure of the color of light, usually expressed in nanometeres (nm) or microns (*m)? correct answer: Wavelength What do you call a technique of sending signals of several different wavelengths of light into the fiber simultaneously? correct answer: Wavelength Division Multiplexing (WDM) The difference (in dB) between the power budget and the loss budget (i.e. the excess power margin) is known as what? corre...
