You work as a network technician. Your boss is interested in the QoS technology in the context ofvideo traffic. What can be said of application of this technology in this type of network？（）
A . The access layer is the initial point at which traffic enters the network. Traffic is marked （orremarked） at Layers 2 and 3 by the access switch as it enters the network， or is "trusted" that it isentering the network with the appropriate tag
B . No traffic marking occurs at the core layer. Layer 2/3 QoS tags are trusted from distributionlayer switches and used to prioritize and queue the traffic as it traverses the core
C . Traffic inbound from the access layer to the distribution layer can be trusted or reset dependingupon the ability of the access layer switches. Priority access into the core is provided based onLayer 3 QoS tags
D . IP precedence， DSCP， QoS group， IP address， and ingress interface are Layer 2 characteristics that are set by the access layer as it passes traffic to the distribution layer. Thedistribution layer， once it has made a switching decision to the core layer， strips these off
E . MAC address， Multiprotocol Label Switching （MPLS）； the ATM cell loss priority （CLP） bit， theFrame Relay discard eligible （DE） bit， and ingress interface are established by the voicesubmodule （distribution layer） as traffic passes to the core layer
F . The distribution layer inspects a frame to see if it has exceeded a predefined rate of trafficwithin a certain time frame， which is typically a fixed number internal to the switch. If a frame isdetermined to be in excess of the predefined rate limit， the CoS value can be marked up in a waythat results in the packet being dropped

B . ...will generate frames with two 802.1Q headers to cause the switch to forward the frames to a VLAN that would be inaccessible to the attacker through legitimate means.
C . ...uses DTP to negotiate trunking with a switch port and captures all traffic that is allowed on the trunk.
D . ...tags itself with all usable VLANs to capture data that is passed through the switch， regardless of the VLAN to which the data belongs.

听力原文： Is your family interested in buying a dog？ A dog can be a happy addition to your family, but if you choose the wrong kind of dog, the consequences can cause you a lot of trouble.
Families should sit down and thoroughly discuss the problems involved before buying a dog. [29] Even if the children in your family are the ones who want the dog, the parents are the ones who are really responsible for seeing that the animal is properly cared for. If you don't know much about dogs, it's a good idea to go to the library or the ASPCA for books about various kinds of dogs, as well as books about how to train a puppy. In reading about the different breeds, you should know that a dog described as very alert may be too jumpy and bouncy. When a book describes a dog as an ideal hunting dog, it probably means that the dog won't be happy living in a small apartment. Dog breeds vary in popularity as the years go by. [30] One of the most popular dogs these days is the German shepherd, this is because it provides protection as well as comRanionship. The family should be warned that these dogs grow up to be very big, and may be too powerful for children to handle. If space is limited, a toy dog may be a good choice. There dogs are very small and easy to train. [3] They don't need to be walked daily, since they can exercise in the space available in the home.

A friend of mine named Paul received an automobile from his brother as a Christmas present. On Christmas Eve when Paul came out of his office, a street urchin was walking around the shiny new car, admiring it. “Is this your car, Mister？” he asked.
Paul nodded. “My brother gave it to me for Christmas.” The boy was astounded. “You mean your brother gave it to you and it didn’t cost you nothing？ Boy, I wish….” He hesitated. Of course Paul knew what he was going to wish for. He was going to wish he had a brother like that. But what the lad said jarred Paul all the way down to his heels.
“I wish,” the boy went on, “that I could be a brother like that.”
Paul looked at the boy in astonishment, then impulsively he added, “Would you like to take a ride in my automobile？”
“Oh yes, I’d love that.”
After a short ride, the boy turned and with his eyes aglow, said, “Mister, would you mind driving in front of my house？”
Paul smiled a little. He thought he knew what the lad wante d. He wanted to show his neighbors that he could ride home in a big automobile. But Paul was wrong again. “Will you stop where those two steps are？” the boy asked.
He ran up the steps. Then in a little while Paul heard him coming back, but he was not coming fast. He was carrying his little crippled brother. He sat him down on the bottom step, then sort of squeezed up against him and pointed to the car.
“There she is, Buddy, just like I told you upstairs. His brother gave it to him for Christmas and it didn’t cost him a cent. And some day I’m gonna give you one just like it…, then you can see for yourself all the pretty things in the Christmas windows that I’ve been trying to tell you about.”
Paul got out and lifted the lad to the front seat of his car. The shining-eyed older brother climbed in beside him and the three of them began a memorable holiday ride. That Christmas Eve, Paul learned what Jesus meant when he had said: “It is more blessed to give….”
