Question: What is the primary function of self-optimization for CPAC in relation to PSCell addition or change failure?
Option 1: To detect and correct Too Early CPC/CPA Execution failures
Option 2: To optimize handover procedures between different SNs
Option 3: To identify and resolve CPAC failures due to incorrect PSCell selection or execution timing issues
Option 4: To improve UE measurement reporting accuracy
Explanation: The correct answer is Option 3 because self-optimization for CPAC is responsible for detecting and resolving CPAC failures that occur due to Too Late CPC Execution, Too Early CPC/CPA Execution, or CPC/CPA execution to the wrong PSCell. This involves identifying and resolving issues related to incorrect PSCell selection or execution timing problems.
