A network designer must provide a rationale to a customer for a design which will move an enterprise from a flat network topology to a hierarchical network topology. Which two features of the hierarchical design make it the better choice? (Choose two.)

• lower bandwidth requirements

• reduced cost for equipment and user training

• easier to provide redundant links to ensure higher availability

• less required equipment to provide the same performance levels

• simpler deployment for additional switch equipment

What is a collapsed core in a network design?

• a combination of the functionality of the access and distribution layers

• a combination of the functionality of the distribution and core layers

• a combination of the functionality of the access and core layers

• a combination of the functionality of the access, distribution, and core layers

What is a definition of a two-tier LAN network design?

• access and core layers collapsed into one tier, and the distribution layer on a separate tier

• access and distribution layers collapsed into one tier, and the core layer on a separate tier

• distribution and core layers collapsed into one tier, and the access layer on a separate tier

• access, distribution, and core layers collapsed into one tier, with a separate backbone layer

What is a basic function of the Cisco Borderless Architecture distribution layer?

• acting as a backbone

• aggregating all the campus blocks

• aggregating Layer 3 routing boundaries

• providing access to end user devices

Which two previously independent technologies should a network administrator attempt to combine after choosing to upgrade to a converged network infrastructure? (Choose two.)

• user data traffic

• VoIP phone traffic

• scanners and printers

• mobile cell phone traffic

A local law firm is redesigning the company network so that all 20 employees can be connected to a LAN and to the Internet. The law firm would prefer a low cost and easy solution for the project. What type of switch should be selected?

• fixed configuration

• modular configuration

• stackable configuration

• StackPower

What are two advantages of modular switches over fixed-configuration switches? (Choose two.)

• lower cost per switch

• increased scalability

• lower forwarding rates

• need for fewer power outlets

• availability of multiple ports for bandwidth aggregation

Which type of address does a switch use to build the MAC address table?

• destination IP address

• source IP address

• destination MAC address

• source MAC address

Which network device can be used to eliminate collisions on an Ethernet network?

• firewall

• hub

• router

• switch
