CCNA 4 - Chapter 5

1 Which rule should be followed when implementing the security requirements of a network design?
#Avoid reducing security in order to add additional network capabilities.

2 What limitations of the 2960 switch prevent it from providing the services needed in the
Distribution layer?

#It does not support route summarization.

3 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?
#voice-level quality of service

4 Which three design requirements are implemented at the access layer? (Choose three.)
#PoE
#VLANs
#QoS traffic classification and marking

5 Refer to the exhibit. Which statement is true regarding how the ISP router filters traffic?
#All traffic from the 64.100.0.0/21 network can access the Internet.

6 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
#coverage

7 What are three features of a Catalyst 2960 switch? (Choose three.)
#redundant power availability
#SNMP
#switch clustering

8 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.)
#lightweight access points
#Catalyst 2960 switches

9 Which two statements are true regarding the following extended ACL? (Choose two.)
#access-list 101 deny tcp 172.16.3.0 0.0.0.255 any eq 20
 access-list 101 deny tcp 172.16.3.0 0.0.0.255 any eq 21
 access-list 101 permit ip any any
#Telnet traffic originating on network 172.16.3.0/24 is denied.

10 Which statement applies to a large network with thousands of nodes?
#Intrusion detection is more likely to be performed by a separate device rather than integrated into a switch or router

11 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.)
#Cisco wireless LAN controller
#lightweight access points

12 What type of WAN service is Frame Relay?
#packet switched

13 Refer to the exhibit. What is an advantage of having two links connected between the two switches shown?
#provides connectivity when one of the connections between the switches fails

14 What is the function of the access layer in the Cisco three-layer hierarchical internetworking model?
#provides QoS classification and marking

15 When applying network security, what security measure should be implemented first?
#securing the network devices

16 What characteristic of a network supports high availability?
#redundancy

17 What is integrated into a Cisco IP phone to reduce the number of ports needed in the wiring closet?
#switch

18 Which network design process identifies where to place access points?
#site survey

19 Using expandable, modular network devices is a key element of what network design criteria?
#scalability

20 What is a primary function of a wireless LAN controller?
#tuning each AP channel for optimal coverage

21 What characteristic in a routing protocol allows it to support the network design criteria for availability?
#fast convergence

22 A network designer is evaluating the network security implementation for an organization. The designer recommends adding network security devices in front of the server farm, although network security devices have been deployed in the Enterprise Edge for two years. What type of attack can be effectively prevented with this recommendation?
#internal attack

23 Refer to the exhibit. The branch office needs constant access to the servers in the enterprise headquarters. Therefore, a backup Frame Relay link is added. A network administrator is configuring the routers in the branch office to make sure that when the backup Frame Relay link is used, only the traffic to  access the enterprise headquarters is allowed. Which statement is true about the routing configuration on branch office edge routers?
#The command ip route 128.107.0.0 255.255.0.0 serial 0/0 50 should be configured on BE2.

24 An automobile sales company is establishing a new, small sales showroom in a downtown area. To update the inventory database, the new sales office will need a WAN connection to the headquarters that is located in the suburban area. The WAN
connection should be around a 4 Mb/s connection. Which WAN service will provide the most economical approach to meet the requirement?
#DSL

25 A network designer is selecting a WAN technology for connections between the headquarters of an organization and its branch offices. In this context, what is one advantage of choosing Frame Relay over a T1 line?
#flexible bandwidth
