CompTIA Network+ Practice Test 2025 – Comprehensive Exam Prep

Utilizing NetFlow in network management primarily serves the purpose of analyzing network traffic and usage patterns. This is integral for network administrators as it provides valuable insights into the types of traffic flowing through the network, which can help in performance monitoring, capacity planning, and identifying unusual network behavior. By aggregating flow data, administrators can understand bandwidth consumption, user activity, and application performance, leading to informed decisions regarding resource allocation and network optimization.

The other options do not relate closely to NetFlow's functionality. Encrypting data transmissions is a security task that involves protocols like SSL/TLS rather than flow analysis. Facilitating hardware upgrades pertains more to physical infrastructure planning and management rather than analyzing traffic data. Monitoring emails sent from the network typically falls under email security solutions and not traffic analysis, which is the primary focus of NetFlow.
