Which statement correctly describes Class of Service (COS) routing? A. It determines the route a packet takes based on the path’s cost.
B. It makes routing decisions based on the packet’s Type of Service (ToS) bits.
C. It looks up route information from an administrator-configured database.
D. It makes routing decisions based on the packet’s service category.
The correct answer is B. It makes routing decisions based on the packet’s Type of Service (ToS) bits.
Class of Service (COS) routing involves prioritizing packets based on specific criteria, often indicated by ToS bits. These bits help determine how packets are treated by the network, influencing routing based on factors like priority and bandwidth requirements. This ensures that more important traffic can be prioritized over less critical traffic, enhancing overall network performance.
