directing data packets to destination hosts on other networks. What are two functions that are provided by the network layer? (Choose two.) The tracert command is used to display the path that a packet travels to its destination.ġ2. The netstat –s command is used to display per-protocol statistics. On a router, the show ip route command is used to display the routing table. 
On a Windows host, the route print or netstat -r commands can be used to display the host routing table.
Devices can be configured with a higher transmission priority. 
A jam signal indicates that the collision has cleared and the media is not busy. All of the devices on a segment see data that passes on the network medium. After detecting a collision, hosts can attempt to resume transmission after a random time delay has expired. A device listens and waits until the media is not busy before transmitting. The device with the electronic token is the only one that can transmit after a collision. What are three characteristics of the CSMA/CD process? (Choose three.) It accepts Layer 3 packets and decides the path by which to forward the packet to a remote network.ĩ. It shields the upper layer protocol from being aware of the physical medium to be used in the communication. It converts a stream of data bits into a predefined code. It generates the electrical or optical signals that represent the 1 and 0 on the media. What is one main characteristic of the data link layer? A packet that has crossed four routers has changed the destination IP address four times.Ĩ. Destination and source MAC addresses have local significance and change every time a frame goes from one LAN to another. Every time a frame is encapsulated with a new destination MAC address, a new destination IP address is needed. Destination MAC addresses will never change in a frame that goes across seven routers. 
Destination IP addresses in a packet header remain constant along the entire path to a target host. Which two statements are correct about MAC and IP addresses during data transmission if NAT is not involved? (Choose two.) When a switch configuration includes a user-defined error threshold on a per-port basis, to which switching method will the switch revert when the error threshold is reached?ħ. In the case of host A sending information to host B, the source address is AA:AA:AA:AA:AA:AA and the destination address is the MAC address assigned to the R2 Ethernet interface, BB:BB:BB:BB:BB:BB.Ħ. The destination address will be the router interface that connects to the same network. The source address will be the originating host device. When a host sends information to a distant network, the Layer 2 frame header will contain a source and destination MAC address.
