Which of the following is considered a Layer 2 device?
Switches are generally considered layer 2 devices, but many are capable of operating at layers 3, 4 or higher. Most hubs are amplifying the electrical signal; therefore, they are really repeaters with several ports. Hubs and repeaters are Layer 1 (physical layer) devices.
What layer of the OSI model does NAT operate?
Layer 3
What three network devices operate at the Data-link layer of the OSI?
The network layer or layer 3 is where you would expect to find routers or possibly layer 3 switches. The network layer is the point where different networks can converge. Routing tables held on layer 3 devices are the path out of the network. If you look at your ipconfig information with the /all switch you will see an address given for default gateway. This will point to the router that is aware of all other networks or sub networks you have access to. In the home this is usually the inside or private address of your DSL or cable modem. I understand some bridges operate at layer 3 as well. At layer 3 Ethernet frames are formed into packets in preparation for routing between networks or sub networks. Because the OSI layer is as implied open there are many examples of software and hardware that can operate at the network layer but router would be the best answer most of the time.
A non routable protocol does not operate in which layer of the OSI model?
Network Layer
Which three commands can be used to help troubleshoot Layer 3 connectivity issues?
PING, Netstat & Tracert
Do connectivity devices such as hubs and repeaters operate at the Presentation layer of the OSI Model?
No. Only protocols that users can see on their screen are considered Presentation Layer based. Hubs and repeaters operate on the physical layer, because it doesn't do anything with the data, it simply forwards it.
What devices operate only at the Physical layer of the OSI model?
All network devices have some component that operates at layer 1. Only hubs and repeaters operate entirely at layer 1.
Devices found in each OSI model?
1. Repeaters (Operate at the OSI Physical Layer).2. Bridges (Operate at the OSI Data Link Layer).3. Routers {and Brouters} (Operate at the OSI Network Layer).
What are the devices that work on physical layer?
1) Physical layer is the first layer. 2) The simplest ones operate at the physical layer are: Repeaters, conventional hubs and transceivers. 3)These devices have absolutely no knowledge of the contents of a message. They just take input bits and send them as output. Cheers, AceInfo Solutions.
You want to use the OSI reference model to troubleshoot a repeater Which OSI layer will you focus on?
Repeaters operate at the physical layer of the OSI model.
What layer of OSI model is multipurpose devices on?
If devices are within the same network then they operate at the second layer.
Which layer 1 devices can be used extend the area covered by a single LAN segment?
Repeaters and hubs

In which layer of osi model dose repeater works?
It depends on what kind of model it is, but in the model for computer 321O, it is on the layer between trhe keyboard and the behind screen, and there is a button with the osi code and there says everything.
Which hardware devices can operate at any layer of the OSI model?
Gateway
What devices operate at the session layer of OSI model?
Gateway network device
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.
