A user opens three browsers on the same PC to access www.cisco.com to search for certification course information. The Cisco web server sends a datagram as a reply to the request from one of the web browsers. Which information is used by the TCP/IP protocol stack in the PC to identify which of the three web browsers should receive the reply?

data link layer addressing detection of errors through CRC calculations delimiting groups of bits into frames

What are the three primary functions provided by Layer 2 data encapsulation? (Choose three.)

A single packet can be sent to a group of hosts. Multicast transmission can be used by routers to exchange routing information. Routers will not forward multicast addresses in the range of 224.0.0.0 to 224.0.0.255.

What are three characteristics of multicast transmission? (Choose three.)

It is not affected by EMI or RFI. It is more expensive than UTP cabling is.

to identify missing segments at the destination to reassemble the segments at the remote location

What are two ways that TCP uses the sequence numbers in a segment? (Choose two.)

It places information in the frame allowing multiple Layer 3 protocols to use the same network interface and media.
