44What are two functions of the data link layer? (Choose two.) It segments and reorders the data. It exchanges data between programs that are running on the source and destination hosts. It controls how data is placed onto the media. It generates signals to represent the bits in each frame. It encapsulates each packet with a header and a trailer to transfer it across the local media.
45Refer to the exhibit. A host is connected to hub 1. Which combination of IP address, subnet mask, and default gateway can allow this host to function in the network?
IP address: 172.16.31.63 Subnet mask: 255.255.255.224 Default gateway: 172.16.31.35 IP address: 172.16.31.29 Subnet mask: 255.255.255.248 Default gateway: 172.16.31.35 IP address: 172.16.31.32 Subnet mask: 255.255.255.224 Default gateway: 172.16.31.35 IP address: 172.16.31.29 Subnet mask: 255.255.255.240 Default gateway: 172.16.30.1 IP address: 172.16.31.37 Subnet mask: 255.255.255.224 Default gateway: 172.16.31.35 46Refer to the exhibit. Each media link is labeled. What type of cable should be used to connect the different devices?
47Which OSI layer offers ordered data reconstruction services?
48Which three statements are true about transport layer protocols? (Choose three.) TCP and UDP manage communication between multiple applications. TCP retransmits the packets for which the acknowledgment is not received. TCP acknowledges received data. UDP exchanges frames between the nodes of the network. TCP has no mechanism to acknowledge transmission errors. UDP uses windowing and sequencing to provide reliable transfer of data.
