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 reviews the low-level design of a company's enterprise network and advises optimizing the STP convergence time. Which functionality must be to Gi1/0/1-10 to follow the architect's recommendation?

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.)

A large chain of stores currently uses MPLS-based T1 lines to connect their stores to their data center. An architect must design a new solution to improve availability and reduce costs while keeping these considerations in mind:
- The company uses multicast to deliver training to the stores.
- The company uses dynamic routing protocols and has implemented QoS.
- To simplify deployments, tunnels should be created dynamically on the hub when additional stores open.
Which solution should be included in this design?

Refer to the exhibit. An engineer working for a telecommunication company with an employee ID:
1234:56:789 is calculating STP scalability for switches to ensure that the numbers are below the maximum supported value for STP logical ports. How many logical interfaces are active for switch A?
