E . reserve bandwidth

Answer: A B D

Explanation:

AppQoS can modify the DSCP (Differentiated Services Code Point) values in IP packet headers. This is crucial for defining the level of service for each packet, influencing how network devices prioritize traffic.

It can assign traffic to specific forwarding classes. This feature allows network administrators to group different types of traffic (e.g., VoIP, streaming, bulk data) into categories that are treated differently based on predefined network policies, ensuring that critical applications receive the necessary bandwidth and priority.

AppQoS is capable of rate-limiting traffic, which involves setting a maximum bandwidth limit for certain types of traffic. This ensures that no single application or service consumes more bandwidth than allocated, thus preventing network congestion and ensuring fair bandwidth distribution among all applications.

These features are essential for managing network performance and ensuring that critical applications receive the necessary resources to function effectively. AppQoS does not inherently include capabilities to re-write TTL (Time To Live) values or reserve bandwidth as primary functions, but it manages bandwidth usage through rate limiting and priority settings.
