Question 11 of 25

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
Correct

Incorrect
Question 12 of 25

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
Correct

Incorrect
Question 13 of 25

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.
Correct

Incorrect
Question 14 of 25

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.
Correct

Incorrect
