Tuesday, November 29, 2011

1. What two traffic types must be included when calculating the bandwidth requirements to support a voice stream in an IP telephony network? (Choose two.)

voice queues
voice carrier stream
voice services traffic
call control signaling
routing updates
2. What are three properties of peer-to-peer applications? (Choose three.)
require dedicated bandwidth allocation
can be used in video conference applications
may require real-time interaction between peer devices
can be used to fulfill the requirements for IP phone calls
may require a direct physical connection between devices
require centralized authentication
3. What are the 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
4. 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
higher availability
lower bandwidth requirements
5. During an evaluation of the currently installed network, the IT staff performs a gap analysis to determine whether the existing network infrastructure can support certain new features. At which stage of the Cisco Lifecycle Services approach does this activity occur?
prepare phase
plan phase
design phase
implement phase
operate phase
optimize phase
6. Which phase of the Cisco Lifecycle Services strategy may prompt a network redesign if too many network problems and errors arise in the network?
prepare
plan
design
implement
operate
optimize
7. Which portion of the enterprise network provides access to network communication services for the end users and devices that are spread over a single geographic location?
enterprise edge
campus module
WAN module
Internet edge
data center
8. Which family of Cisco switches is specifically designed for data centers?
Catalyst 6500
Catalyst 2000
Nexus 7000
Catalyst 4500
9. What type of specialized memory is used to facilitate high performance switching in Cisco multilayer switches?
content-addressable memory (CAM)
ternary content addressable memory (TCAM)
address resolution protocol (ARP) memory
Cisco Express Forwarding (CEF) memory
10. Which Catalyst 6500 switch component integrates on individual line modules as well as on the supervisor engine?
CPU
Flash
ASIC
NVRAM
11. Which technology consistently increases CPU load on multilayer Catalyst switches?
quality of service (QoS)
access control lists (ACLs)
policy-based routing (PBR)
network address translation (NAT)
12. Which family of Cisco switches supports Fibre Channel over Ethernet (FCoE)?
Catalyst 4948G
Catalyst 4500
Catalyst 6500
Nexus 5000
13. Which family of Cisco switches supports the greatest number of slots?
Catalyst 4500
Catalyst 6500
Nexus 5000
Nexus 7000
14. Which two features are unavailable on a Layer 2 switch? (Choose two.)
use of ASICs
Internet Group Management Protocol (IGMP) snooping
QoS marking
Time to Live (TTL) decrementing
rewrite of the source and destination MAC addresses
15. What is the purpose of the Cisco Enterprise Architecture?
It replaces the three-layer hierarchical model with a flat network approach.
It provides an enterprise-wide system network architecture that helps protect, optimize, and grow the network infrastructure that supports the business processes of a company.
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.
16. On what is Layer 3 switching fundamentally based?
access control
the ability to circumvent CPU processing
software-based forwarding
Parallel eXpress Forwarding (PXF)
17. 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?
access
core
distribution
control
18. In its network design, a company lists this equipment:
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
lightweight access points
Catalyst 2960 switches
19. Which protocol is required for Cisco Express Forwarding to be able to successfully forward packets on a multilayer switch?
Cisco Discovery Protocol
Spanning Tree Protocol
Address Resolution Protocol
Dynamic Trunking Protocol
VLAN Trunking Protocol
