What layer of the Open Systems Interconnection model is responsible for the logical addressing of end systems and the routing of datagrams on a network?
Layer 3 (network layer).
Which data link layer addressing scheme is used in a point-to-point logical topology?
Layer 2 addressing not required for this topology
Which OSI layer defines the functions of a router?
Network Layer - Does path determination and logical addressing.
What are three things included in a logical topology document?
the path that the data takes through a network the device names and Layer 3 addressing information the location of routing, network address translation, and firewall filtering
Why do you need a network?
The network layer is responsible for addressing nodes in a logical way. It is also responsible for making decisions on routing a packet from one network to another. Without the network layer it would not be possible to send a packet outside of your own local network.
Discuss the need or lack of need for a network layer OSI layer 3 in a broadcast network?
The network layer is responsible for addressing nodes in a logical way. It is also responsible for making decisions on routing a packet from one network to another. In a broadcast network, routing is not needed. A transmission from any attached station is received by all other attached stations. Other functions,such as sequencing, flow control, error control, can be done at layer 2. The MAC sublayer is responsible for addressing across the LAN. With the Data link layer and its sublayers (MAC & LLC), no network layer is needed.
What layer of the tcpip stack represents logical addressing and determins the best path through the network?
INTERNET
What layer of the TCP stack represents logical addressing and determines the best path through the network?
Internet
In a three-layer hierarchical network design which distribution layer function delineates broadcast domains?
routing between VLANs
What is main function is to examine packetes and determine where to direct them based on their Network layer addressing information?
This is the main function of a router.
Is ARP the core protocol responsible for logical addressing?
The structure of the question is meant to trick you because 'logical addressing' is being used loosely. Technically, IP is the CORE protocol responsible for logical addressing. ARP is the network layer protocol that is used to discover the identity(physical address) of a machine whose IP address you know. Very briefly, it does this by creating a database that maps the MAC address to the (hosts') logical address provided.
Which layer of the OSI model is primarily concerned with accessing the physical media and physical addressin?
The Physical layer is responsible for the actual hardware connection. The physical addressing is handled by the Data Link Layer.
