A system administrator is concerned about a high number of visitors connecting to a company’s network. In
addition to the production network traffic, the network infrastructure is used for the systems management traffic
to the company’s servers.
What should the administrator do to separate traffic?

A.
Implement dynamic routing using the Open Shortest Path First (OSPF) protocol.

B.
Split the traffic using the Virtual Local Area Networks (VLAN).

C.
Create multiple Spanning Tree Protocol (STP) instances to carry different types of traffic.

D.
Change the priority of the traffic using the Quality of Service (QoS) feature.

Explanation:

Quality of service (QoS) protocols allow a router to distinguish different classes of traffic and serve each class according to its priority and needs.
