Which feature in Fortinet helps manage bandwidth allocation across a network?

C. Traffic shaping is the correct answer because it specifically refers to the process of controlling and managing the data transmission rates across a network. This feature helps prioritize certain types of traffic over others and allocates bandwidth effectively to ensure optimal performance and resource utilization. By using traffic shaping, network administrators can set limits on the amount of bandwidth that can be used by specific applications or services, which is particularly useful in environments where bandwidth is limited or needs to be allocated efficiently across competing demands.

Traffic shaping allows for smoother network performance, reducing latency for critical applications and preventing any one application from consuming all available bandwidth. It’s a proactive technique that not only enhances user experience but also helps in maintaining service level agreements (SLAs) by ensuring required performance metrics are met.

In contrast, the other options focus on different aspects of network management. Traffic rerouting deals with redirecting data packets along alternative paths, traffic logging pertains to the documentation of network traffic for analysis or troubleshooting, and traffic filtering involves controlling which data packets are allowed or blocked based on predetermined rules. None of these options specifically address bandwidth management in the way that traffic shaping does.
