Which statements are true regarding traffic shaping in an application sensor and firewall policy? (Choose two.)

• A. Shared traffic shaping cannot be used
• B. Only traffic matching the application control signature is shaped
• C. It can limit bandwidth usage of heavy traffic applications
• D. Per-IP traffic shaping cannot be used

Answer: (B)

The correct choice highlights an important aspect of how application control works within a firewall policy. Traffic shaping, when applied in the context of application sensors and firewall policies, specifically targets traffic that matches application control signatures. This means that only the traffic identified through these signatures will undergo the shaping process, allowing for more precise control over bandwidth allocation based on the application types and their behaviors. For example, if an application control signature identifies a video streaming service, the traffic shaping rules will only affect packets that are a part of that service's communication. This capability is essential for prioritizing or limiting bandwidth for specific applications, ensuring that critical business applications receive the necessary resources while managing or capping less critical ones. The other options do not accurately reflect how traffic shaping functions in this context. The mention of shared traffic shaping implies a broader application than what is applicable only to specific signatures targeted by the application control feature. Per-IP traffic shaping refers to managing bandwidth on a per-user basis, which might be a different configuration from what application sensors implement. Therefore, understanding the specificity with which application sensors interact with traffic shaping is crucial.
