CCNA Discovery 4 Module 5 Scored 100%

1 Which three design requirements are implemented at the access layer? (Choose three.)
high-density routing
packet filtering
rapidly converging routing protocols
**QoS traffic classification and marking

2 When applying network security, what security measure should be implemented first?
**securing the network devices
implementing the firewalls or filters at the enterprise edge
applying security to resources accessed by internal users
applying ACLs to the interfaces of the routers in the internal network

3 What are three features of a Catalyst 2960 switch? (Choose three.)
network layer functionality
**redundant power availability
route summarization
**switch clustering
inter-VLAN routing

4 Which rule should be followed when implementing the security requirements of a network design?
Always use a common security plan for all business needs.
As standard practice, lower access restrictions for users if cost is too high.
**Avoid reducing security in order to add additional network capabilities.
When possible, implement an IDS to protect users from spam.

5 Using expandable, modular network devices is a key element of what network design criteria?


Refer to the exhibit. What is an advantage of having two links connected between the two switches shown?
provides redundancy in case one of the switches fails
provides connectivity to Switch1 when the link to the server fails
**provides connectivity when one of the connections between the switches fails
provides power to the other switch when the other switch has lost AC power

7 When considering converged network designs, it is important to identify appropriate service demands. What is a concern when preparing a network design to fit this environment?
business data compensation for sensitivity to noise
location and placement of firewalls
**voice-level quality of service
security policy requirements

8 What is the function of the access layer in the Cisco three-layer hierarchical internetworking model?
**provides QoS classification and marking
implements a fast-converging routing protocol
uses routed interconnections between devices
aggregates traffic and performs route summarization

9 Which network design process identifies where to place access points?
**site survey
risk assessment
scalability design
network protocol analysis

10 What characteristic in a routing protocol allows it to support the network design criteria for availability?
CIDR support
**fast convergence
timed updates
VLSM support

11 What characteristic of a network supports high availability?
high-bandwidth paths to servers
wireless management

12 What is a primary function of a wireless LAN controller?
**tuning each AP channel for optimal coverage
providing PoE to the wireless clients
distributing VLAN information to the wireless clients
serving as the point of connection between wireless clients and the wired LAN

13 Which two factors should be considered when designing a wireless LAN that provides seamless roaming capabilities? (Choose two.)
**use of a wireless controller to manage IP addressing
type of routing protocols
location of existing wired clients
position of MDF

14 A company lists this equipment in their network design:
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 would be appropriate to use at the access layer to provide end-user connectivity? (Choose two.)
Catalyst 4503 switches
Cisco 1841 router
Catalyst 6509 switches
**lightweight access points
**Catalyst 2960 switches

15 What limitations of the 2960 switch prevent it from providing the services needed in the Distribution layer?
It is limited to copper connections.
It does not support QoS.
It does not support voice VLAN capability.
**It does not support route summarization.

16 A state-funded college wants to implement Cisco wireless IP phones for employees to use while on campus. The college currently has only wired network device access. Which two devices must be incorporated into the network design to best accommodate roaming for wireless IP phones? (Choose two.)
voice VLAN capable switch
autonomous AP
PoE switch
**Cisco wireless LAN controller
2960 switch with 48 100-Mb ports
**lightweight access points

17 What type of WAN service is Frame Relay?
cell switched
**packet switched
circuit switched

18 What is integrated into a Cisco IP phone to reduce the number of ports needed in the wiring closet?
firewall appliance


Refer to the exhibit. Which statement is true regarding how the ISP router filters traffic?
Traffic from the address to any destination on the Internet is denied.
Traffic from any source address entering the ISP router interface s0/0/0 is permitted.
Only traffic with a source address of is allowed into the ISP router interface s0/0/0.
**All traffic from the network can access the Internet.
Traffic from any source address can access the network.

20 Which two statements are true regarding the following extended ACL? (Choose two.)

access-list 101 deny tcp any eq 20
access-list 101 deny tcp any eq 21
access-list 101 permit ip any any
**FTP traffic originating from network is denied.
All traffic is implicitly denied.
FTP traffic destined for the network is denied.
Telnet traffic originating on network is denied.
**Web traffic originating from is permitted.

21 Which statement applies to a large network with thousands of nodes?
Each wireless phone is normally in a separate VLAN for security reasons.
Multiple firewalls exist throughout the access layer for maximum security protection.
Firewalls cannot be implemented in the multilayer switches and routers.
**Intrusion detection is more likely to be performed by a separate device rather than integrated into a switch or router.
