Identify the tool employed by Blake to detect high resource utilization over the organizational network.

The tool that Blake would likely utilize for detecting high resource utilization across the organizational network is Nagios. This tool is designed specifically for monitoring systems, networks, and infrastructure. Nagios allows administrators to monitor the health and performance of various system resources, such as CPU usage, memory load, disk space, and network traffic, providing alerts when thresholds are breached.

In the context of network performance and resource utilization, Nagios can actively check the status of various services and host resources, making it well-suited for identifying issues related to resource consumption in real-time. Additionally, it provides a comprehensive overview of system performance, which can be crucial for maintaining the operational integrity of IT infrastructure.

While other tools such as Wireshark and Splunk have their own monitoring and analysis capabilities, they focus on different aspects of network management. Wireshark is primarily a network protocol analyzer that captures and inspects data packets, while Splunk specializes in aggregating and analyzing machine data across various IT systems. AIDA64 Extreme, on the other hand, is typically used for hardware monitoring, benchmarking, and diagnostics, focusing more on individual system performance rather than network-wide resource utilization.
