Company XYZ is designing their network using the three-layer hierarchical model. At which layer must the QoS design classify or mark the traffic?
Company XYZ is migrating their existing network to IPv6 and they must plan for Layer 2 and Layer 3 devices Some of the access layer switches do not support IPv6, however, core and distribution switches fully support unicast and multicast routing. The company wants to minimize cost of the migration. Which migration strategy should be used in the design?
