An organization is designing a detailed QoS plan that limits bandwidth to specific rates. Which two parameters are supported be the traffic policing feature? (Choose two.)

Refer to the exhibit. An architect must design a solution to connect the two ASs. To optimize bandwidth, the design will implement load sharing between router R6 and router R4. Which solution should the design include?

What is an advantage of designing an out-of-band network management solution?

An architect is designing a multicast solution for a network that contains over 100 routers. The architect plans to create several multicast domains and balance the PIM-SM traffic within the network. Which technology should the architect include in the design?

A customer's current Layer 2 infrastructure is running Spanning Tree 802.1d, and all configuration changes are manually implemented on each switch. An architect must redesign the Layer 2 domain to achieve these goals:
reduce the impact of topology changes
reduce the time spent on network administration
reduce manual configuration errors
Which two solutions should the architect include in the new design? (Choose two.)
