What plane on a network device is accessed using SSH or SNMP?
Correct!

management plane

control plane

forwarding plane

CAM

Question 2
1 / 1 pts
What feature of CEF allows for Layer 3 switches to use multiple paths?
Correct!

load-balancing

hardware based forwarding

route caching

Netflow LAN switching

Question 3
1 / 1 pts
Which statement is true about the CEF forwarding process?

The FIB table contains the Layer 2 rewrite information.

Adjacency table lookups use the closest Layer 3 prefix match.

The adjacency table eliminates the need for the ARP protocol.
Correct!

After an IP prefix match is made, the process determines the associated Layer 2 header rewrite
information from the adjacency table.
Refer to curriculum topic: 4.4.2

You Answered

core Layer BAD

Refer to Chapter 2.

Question 5

Two Catalyst 4503 Layer 3 switches

One 5500 security appliance firewall

Two Catalyst 6509 switches

Two lightweight access points

Two Catalyst 2960 switches

Which two types of devices from the list would be appropriate to use at the access layer to
provide end-user connectivity? (Choose two.)

Catalyst 4503 switches

Cisco 5500 security appliance firewall

Catalyst 6509 switches
Correct!

lightweight access points
Correct!

Catalyst 2960 switches

Refer to curriculum topic: 1.1.3

Question 6
1 / 1 pts
Which layer 3 switching method used by Catalyst switches offers the greatest performance?

process switching
Correct!

CEF

fast switching

TCAM

Refer to Chapter 2 of the Foundation Learning Guide

Question 7
1 / 1 pts
For what is the control plane on a catalyst switch responsible?

the catalyst switch does not have a Control Plane; it has a Management Plane

control and remote management of the switch
Correct!

control of the routing protocols and processes running on the switch

control of the layer 2 switching process used by the switch

Refer to Chapter 2 of the Foundation Learning Guide

Question 8
1 / 1 pts
A user needs to access a file server that is located in another department. Which layer of the
Cisco Hierarchical Network Model will process the traffic first?
Correct!

access

core

distribution

control

Refer to curriculum topic: 1.1.5

Question 9
0 / 1 pts
What is the purpose of the Cisco Enterprise Architecture and the hierarchical desgin?

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

Each element in the hierarchy has a specific set of functions and services that it offers and
specific role.--> Correct Answer
You Answered

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

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

Question 10
1 / 1 pts
Which two features are unavailable on a Layer 2 switch? (Choose two.)

use of ASICs

Internet Group Management Protocol (IGMP) snooping

QoS marking
Correct!

Time to Live (TTL) decrementing
Correct!

rewrite of the source and destination MAC addresses

Question 11
1 / 1 pts
What is true about TCAM lookups that are associated with CEF switching?

TCAM includes only Layer 3 lookup information.
Correct!

A single TCAM lookup provides Layer 2, Layer 3, and ACL information.

TCAM lookup tables are used only for the Layer 3 forwarding operation.

TCAM lookup tables are used only for the rapid processing of ACLs within CEF.

Refer to curriculum topic: 4.4.2

Question 12
1 / 1 pts
Why does extending layer 3 switching to the access layer improve scalability?

VLANs are extended into the distribution layer.
Correct!

VLANs are terminated on the access layer devices.

The access and distribution layers would not participate in the routing scheme.

Layer 3 switching in the access layer is a cheaper implementation option.

Refer to Chapter 2 of the Foundation Learning Guide

Question 13
1 / 1 pts
Which family of Cisco switches is specifically designed for data centers?

Catalyst 6500

Catalyst 2000
Correct!

Nexus 7000

Catalyst 4500

Question 14
0 / 1 pts
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.)
You Answered

reduced cost  BAD
Correct!

Scalability  Correct

less equipment required
Correct Answer

segmentation of broadcast domains  Correct Answer

lower bandwidth requirements

Question 15
1 / 1 pts
What is the suggested solution for routing when Layer 3 routing is extended to the access layer?

run an IGP at the access, distribution and core layers
Correct!

run an IGP between the distribution and core layers and use static default routes at the access
layer

use static rotue from the access to the distribution layer, use default static routes from the
distribtuion to the core layer and use IGP amongst core layer devices

run an IGP between distribution and core layers and rely on proxy ARP between the access and
distribution layers

Question 16
1 / 1 pts
What type of specialized memory is used to facilitate high performance switching in Cisco
multilayer switches?

content-addressable memory (CAM)
Correct!

ternary content addressable memory (TCAM)

address resolution protocol (ARP) memory

Cisco Express Forwarding (CEF) memory

Question 17
1 / 1 pts
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

Correct!

high-speed backbone switching
Correct!
