TCP functions at the Open System Interconnection(OSI)(61)layer, or Layer 4. Its chief responsibility is to ensure(62)end-to-end connectivity. IP, located one layer down, at the OSI network layer, or Layer 3, communicates the addresses of each(63)sender and receiver to the routers along the way. Routers and Layer 3 switches can read IP and other Layer 3(64). This information, combined with routing tables and other network intelligence, is all it takes to get(65)the room or around the world via TCP/IP.

In the open systems interconnection (OSI) reference model, "layer" means one of seven conceptually complete,(71) arranged groups of services, functions, and protocols, that extend across all open systems.Application layer provides means for the application(72) to access the OSI environment. Presentation layer provides for the selection of a common syntax for representing data.(73) layer provides the means necessary for cooperating presentation entities to organize and synchronize their dialog and to manage their data exchange. Transport layer provides a reliable end-to-end data transfer service. Network layer provides for the entities in the transport layer the means for transferring blocks of data, by(74) and switching through the network between the open systems in which those entities reside. Data link layer provides services to transfer data between network layer entities. Physical layer provides the mechanical, electrical, functional, and procedural means to establish, maintain and(75) physical connections for transfer of bits over a transmission medium.

In reference to the P1R3 show isis route output, which statement is true? ()
Routers perform the decision process that selects what path a packet takes. These ( ) layer devices participate it the collection and distribution of network-layer information, and perform Layer 3 switching based on the contents of the network layer ( ) of each packet. You can connect the routers directly by point-to-point ( ) or local-area networks, or you can connect them by LAN or WAN switches. These Layer 2 switches unfortunately do not have the capability to hold Layer 3 ( ) information or to select the path taken by a packet through analysis of its Layer 3 destination address. Thus, Layer 2 switches be involved in the Layer 3 packet ( ) decision process.
