Which of the following allows a network administrator to analyze attacks coming from the Internet without affecting latency?

An Intrusion Prevention System (IPS) actively blocks or prevents attacks in real-time, which can introduce latency as it processes and potentially drops packets. While effective for stopping threats, its active intervention can slow down legitimate traffic, making it less ideal for analyzing attacks without affecting network performance.

A load balancer distributes incoming network traffic across multiple servers to ensure efficiency and reliability. While it optimizes performance and can manage traffic loads, it is not specifically designed for threat detection or analysis and does not provide the capabilities needed to analyze attacks coming from the Internet.

A firewall acts as a barrier between trusted and untrusted networks, controlling incoming and outgoing traffic based on predetermined security rules. While it can block unauthorized access, its primary function is not focused on analyzing attacks; thus, it does not provide the same level of insight into potential threats without potentially affecting latency.
