Which three recommendations may be included in a network design strategy that is focused on scalability? (Choose three.)
Design a hierarchical network.
Use layer 2 devices to filter and reduce network traffic in the core.
Choose routers or multilayer switches to limit broadcasts and filter other undesirable traffic from the network.
Use expandable, modular equipment , or clustered devices that can be easily upgraded to increase capabilities.
Combine the access and distribution layer for easier access and limit the size of the failure domain.
Design a hierarchical network.
Choose routers or multilayer switches to limit broadcasts and filter other undesirable traffic from the network.
Use expandable, modular equipment , or clustered devices that can be easily upgraded to increase capabilities.
