参考答案和解析
正确答案：ACF
A,C,F 解析：Explanation:
A LAN segment with too many hosts can mean that there are a large number of stations contending for bandwidth. It can also mean an increase in the number of collisions on the segment, which can cause further congestion issues.

Broadcast storms are the result of a large number of broadcasts sent over the LAN. Because each station listens to these broadcast messages, congestion can occur quickly. Finally, low bandwidth can simply mean that the LAN can not process all of the LAN traffic that is being sent. This can mean that TCP sessions are retransmitted, which can lead to additional congestion.

Incorrect Answers:
B. This can alleviate congestion, as data can be sent and received at the same time. In addition, collisions are not possible in a full duplex LAN.

D. Multicasting can actually alleviate congestion issues, as single streams of information can reach multiple hosts at the same time, instead of using a series of point to point
connections.

E. Segmentation breaks up a large LAN into multiple, smaller LANS. This will mean fewer hosts per broadcast domain.

  • 第1题：

    You are working as a network technician at Ezonexam University, when you get a call from the Engineering Faculty. They're complaining that they're receiving obsolete information from the Business Faculty's network traffic broadcasts.

    What can you do to contain the Business Faculty's broadcast while still keeping it connected to the internet and the enterprise services of the University? (Select all valid answer choices)

    A. Use half and full-duplex Ethernet on the Engineering Department LAN

    B. Establish a VTP domain to minimize the obsolete traffic

    C. Change the switch IP address of the switch

    D. Create separate VLANs and subnets for the two departments and route between the two

    E. Provide greater bandwidth to the Engineering Department LAN

    F. Place the business department on a separate subnet and route between networks


    正确答案：DF
    D,F 解析：Explanation:
    In order to prevent the broadcast and link level multicast traffic separated between the departments, they need to be isolated at layer two. This can be accomplished in two ways. The first is to create separate VLANs and place each department into a different one. The second method would be to separate the two departments into two completely different networks, and route between them.

    Incorrect Answers:
    A. Mixing the use of half and full duplex will make no difference to the number of broadcasts sent.

    B. Trunking is only useful in networks that already contain VLANs.

    C. This will make no difference, as all users will still be contained within the same IP subnet.

    E. The amount of bandwidth involved will not have any impact on the amount of broadcasts that are sent and received.

    B. Full duplex operation

    C. Broadcast storms

    D. Multicasting

    E. Segmentation

    F. Low bandwidth


    正确答案：ACF
    A,C,F 解析：Explanation:
    Choice A is correct because the more hosts on a broadcast domain, the more traffic that is created. Choice Ccontributes to congestion because broadcast storms can become very problematic, and lead to complete network saturation. Multicasts are similar to broadcasts in their use on a LAN. Finally, if there is not enough bandwidth, traffic sessions can time out. This leads to new transmissions and the re-sending of data, which can lead to more congestion.

    Incorrect Answers:
    B, E. These are incorrect because full duplex operation and segmented networks actually result in less congestion.

    D. Multicasting can actually alleviate congestion issues, as single streams of information can reach multiple hosts at the same time, instead of using a series of point to point connections.
