Answer: D
Explanation:
The Customer Release Notes (CRNs) document collects documented solved known issues, new
issues discovered after the product software has been released, as well as software upgrade
procedures and firmware details. This document is useful for troubleshooting because it can
help identify if a problem is related to a known issue or a software bug, and if there is a
workaround or a solution available. The CRNs also provide information about the software
compatibility and interoperability of different Nokia products and platforms. The other options
are incorrect because the EPTUG and the UPG do not contain information about known issues,
and the CRNs do not provide instructions for automated provisioning, commissioning, and
power balancing functions. Nokia Optical Diagnostics and Troubleshooting Course, Nokia Optical
