Which network layer integrates with the backbone and users to provide intelligent switching, routing, and security?

• Access
• Core
• Distribution

Which network layer provides direct, switched network connectivity to the user?

• Access
• Core
• Distribution

Which network layer provides fault isolation and high-speed backbone switch connectivity?

• Access

Which term describes the ability of a network to use all available network resources and to provide data load sharing?

• Flexible
• Hierarchical
• Modular
• Resilient

Which term is used to describe a network that is always accessible?

• Flexible
• Hierarchical
• Modular
• Resilient

True or false? OSPF is well-suited for larger networks because it can be deployed using a hierarchical design.

• True
• False

What are three important features that should be considered for implementation in a well-designed, scalable network? (Choose three.)

• access layer with only wired devices
• expandable, modular equipment
• multiple links
• redundant links
• static routes

Which three recommendations may be included in a network design strategy that is focused on scalability? (Choose three.)

• Choose routers or multilayer switches to limit broadcasts and filter other undesirable traffic from the network.
• Combine the access and distribution layer for easier access and limit the size of the failure domain.
• Design a hierarchical network.
• Use expandable, modular equipment, or clustered devices that can be easily upgraded to increase capabilities.
• Use Layer 2 devices to filter and reduce network traffic in the core.

Field replaceable line cards are a feature found on which type of switch?

• fixed configuration
• modular
• stackable
• virtual
