- fixed configuration
- modular configuration
- stackable configuration
- StackPower
- StackWise
7. Question
What are two advantages of modular switches over fixed-configuration switches? (Choose two.)
- lower cost per switch
- increased scalability
- lower forwarding rates
- need for fewer power outlets
- availability of multiple ports for bandwidth aggregation
8. Question
Which type of address does a switch use to build the MAC address table?
- destination IP address
- source IP address
- destination MAC address
- source MAC address
9. Question
Which network device can be used to eliminate collisions on an Ethernet network?
- firewall
- hub
- router
- switch
10. Question
What two criteria are used by a Cisco LAN switch to decide how to forward Ethernet frames? (Choose two.)
- path cost
- egress port
- ingress port
- destination IP address
- destination MAC address
11. Question
Refer to the exhibit. Consider that the main power has just been restored. PC3 issues a broadcast IPv4 DHCP request. To which port will SW1 forward this request?

CCNA2 v6.0 Chapter 4 Exam 001
- to Fa0/1 only
- to Fa0/1 and Fa0/2 only
- to Fa0/1, Fa0/2, and Fa0/3 only
- to Fa0/1, Fa0/2, Fa0/3, and Fa0/4
- to Fa0/1, Fa0/2, and Fa0/4 only
12. Question
What is one function of a Layer 2 switch?
- forwards data based on logical addressing
- duplicates the electrical signal of each frame to every port
- learns the port assigned to a host by examining the destination MAC address
- determines which interface is used to forward a frame based on the destination MAC address
13. Question
Refer to the exhibit. How is a frame sent from PCA forwarded to PCC if the MAC address table on switch SW1 is empty?

CCNA2 v6.0 Chapter 4 Exam 002
- SW1 floods the frame on all ports on the switch, excluding the interconnected port to switch SW2 and the port through which the frame entered the switch.
- SW1 floods the frame on all ports on SW1, excluding the port through which the frame entered the switch.
- SW1 forwards the frame directly to SW2. SW2 floods the frame to all ports connected to SW2, excluding the port through which the frame entered the switch.
- SW1 drops the frame because it does not know the destination MAC address.
14. Question
A small publishing company has a network design such that when a broadcast is sent on the LAN, 200 devices receive the transmitted broadcast. How can the network administrator reduce the number of devices that receive broadcast traffic?
- Add more switches so that fewer devices are on a particular switch.
- Replace the switches with switches that have more ports per switch. This will allow more devices on a particular switch.
- Segment the LAN into smaller LANs and route between them.
- Replace at least half of the switches with hubs to reduce the size of the broadcast domain.
15. Question
Refer to the exhibit. How many broadcast domains are displayed?

16. Question
Which solution would help a college alleviate network congestion due to collisions?
- a firewall that connects to two Internet providers
- a high port density switch
- a router with two Ethernet ports
- a router with three Ethernet ports
17. Question
Which network device can serve as a boundary to divide a Layer 2 broadcast domain?
- router
- Ethernet bridge
- Ethernet hub
- access point
18. Question
What is the destination address in the header of a broadcast frame?
- 0.0.0.0
- 255.255.255.255
- 11-11-11-11-11-11
- FF-FF-FF-FF-FF-FF
19. Question
Which statement describes a result after multiple Cisco LAN switches are interconnected?
- The broadcast domain expands to all switches.
- One collision domain exists per switch.
- Frame collisions increase on the segments connecting the switches.
- There is one broadcast domain and one collision domain per switch.
20. Question
What does the term “port density” represent for an Ethernet switch?
- the memory space that is allocated to each switch port
- the number of available ports
- the numbers of hosts that are connected to each switch port
- the speed of each port
21. Question
What are two reasons a network administrator would segment a network with a Layer 2 switch? (Choose two.)
- to create fewer collision domains
- to enhance user bandwidth
- to create more broadcast domains
- to eliminate virtual circuits
- to isolate traffic between segments
- to isolate ARP request messages from the rest of the network
