What are two responsibilities of devices that are located at the core layer of the hierarchical design model? (Choose two.)

• access list filtering

• packet manipulation

• high-speed backbone switching

• interconnection of distribution layer devices

• redundancy between the core devices only

A network designer must provide a rationale to a customer for a design that 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.)

• reduced cost

• Scalability

• less equipment required

• segmentation of broadcast domains

• lower bandwidth requirements

What is the purpose of the Cisco Enterprise Architecture and the hierarchical design ?

• It replaces the three-layer hierarchical model with a flat network approach.

• Each element in the hierarchy has a specific set of functions and services that it offers and specific role.

• It provides services and functionality to the core layer by grouping various components into a single component that is located in the access layer.

• It reduces overall network traffic by grouping server farms, the management server, corporate intranet, and e-commerce routers in the same layer.

Which two statements are true about routed ports on a multilayer switch? (Choose two.)

• To create a routed port requires removal of Layer 2 port functionality with the no switchport interface configuration command.

• A routed port is a physical switch port with Layer 2 capability.

• A routed port is not associated with a particular VLAN.

• A routed port behaves like a regular router interface and supports VLAN subinterfaces.

• The interface vlan global configuration command is used to create a routed port.

Which two network design features require Spanning Tree Protocol (STP) to ensure correct network operation? (Choose two.)

• link-state dynamic routing that provides redundant routes

• removing single points of failure with multiple Layer 2 switches

• implementing VLANs to contain broadcasts

• static default routes

• redundant links between Layer 2 switches

What security benefit is gained from enabling BPDU guard on PortFast enabled interfaces ?

• preventing rogue switches from being added to the network

• protecting against Layer 2 loops

• enforcing the placement of root bridges

• preventing buffer overflow attacks

Forwarding of network traffic from a Layer 2 perspective uses what information ?

• Source IP address

• Destination IP address

• Source MAC address

• Destination MAC address

• Data protocol

Forwarding of network traffic from a Layer 3 perspective uses what information ?

• Source IP address

• Destination IP address

• Source MAC address

• Destination MAC address

• Data protocol

A ___________ forwarding architecture provides increased port density and forwarding scalability.

• Centralized

• Clustered

• Software

• Distributed

What attributes are used to elect a root bridge ?

• Switch port priority

• Bridge priority

• Switch serial number

• Path cost

• Bridge MAC address
