Which devices make layer 3 decisions?
Routers
Which network layer protocol enables routers to discover the best path between networks using hop count?
IP
What is a function of the distribution layer in the hierarchical design model?
provide connectivity between smaller local networks
If data link layer detect error why do you think we need transport layer?
because in the data link layer two routers communitate directly via a physical channel , whereas at the transport layer this physical channel is replaced by the entire subnet. In the data link layer ,it is not necessary for a router to specify which router it wants to talk to each outgoing line uniquely specifies a panicular router . In the transport layer explicit addressing of destinations is required.
Which layer of the hierarchical design model provides a means of connecting devices to the network and controlling which devices are allowed to communicate on the network?
distribution
What is one feature that distinguishes routers from Layer 2 switches?
Routers support a variety of interface types. Switches typically support Ethernet interfaces.
Routers are considered components of which layer?
Routers would be in layer 3 of the OSI model also known as the Network layer.
Routers operate at layer LAN switches operate at layer Ethernet hubs operate at layer?
Routers operate at layer 3. LAN switches operate at layer 2. Ethernet hubs operate at layer 1.
What layer protocol does RIP use?
RIP is a IGP protocol that allows routers to advertise what they know about their routes to other routers. Since routers operate at the network layer (3), so does RIP.
Routers operate at which osi layer?
3
What is the data element for the Transport layer?
routers
Which devices make layer 3 decisions?
Routers
What is the function of routing in the network OSI layer3?
The whole point of the network layer, and layer 3 devices, is to move packets between separate networks. Layer 2 devices on the other hand (switches), only move frames using only the data link layer between hosts in that same network. Without layer 3 devices (routers or gateways), there could be no communication between separate interconnected groups of computers.
In which layer of the TCPIP Model do routers belong?
In the TCP IP model, routers belong in layer 3. This is a common model used in setting up information technology systems.
Which is an important factor when choosing a Layer 2 protocol?
-The geographic scope of the network -The physical layer implementation -The number of hosts to be interconnected
What is the function of the data link layer?
exchanging of data between interconnected devices
Can a layer 2 switch be used in the core of a campus network?
Yes it can and the reason is because of redundancy provides for a backup route or network connection in case of a link failure. The core hardware is typically interconnected to all distribution network hardware and the objective is to ensure that the data traffic continues for the whole network even if a core networking device or link fails.
