For troubleshooting Cisco Contact Center Enterprise (CCE), several tools are available for log collection. The Diagnostic Framework Portico is a centralized, web-based GUI that allows administrators to collect logs and diagnostic data from various CCE components. DUMPLOG is a command-line utility used to capture in-memory trace logs from a specific running CCE process and save them to a file. The Unified System CLI is the command-line interface for VOS-based CCE appliances (like CCE Data Servers), providing commands such as file get activelog to download system and application logs directly from the appliance. These three tools represent the primary methods (GUI, process-specific CLI, and system-level CLI) for log collection.

A. PROCMON: This is a Microsoft Windows Sysinternals utility for real-time monitoring of file system and registry activity, not a CCE-specific tool for downloading logs.

C. OPCTEST: This is a command-line diagnostic tool used to test process connectivity and communication between CCE components, not for collecting log files.

F. RTTEST: This command-line utility is used to test the real-time data feed from the CCE Router process, not for downloading historical or trace logs.
