What layer of OSI model does a router operate?
Router is a Layer 3 (Network Layer)device that checks packet's IP Address at input interface & routes them to interface connected to destination network if available.
What is the method described by the network layer for routing packets from a device on one network to a device on a different network?
A router
Which one of the following is the most commonly used layer 2 network device?
The most commonly used Layer 2 network device is the Ethernet switch. Ethernet switches operate at the data link layer of the OSI model and efficiently forward frames based on MAC addresses, allowing multiple devices to communicate within a local area network (LAN). They help reduce network collisions and enhance overall network performance by creating separate collision domains for each connected device.
What is the Network layer unique identifier assigned to each device on a TCPIP network?
The IP address of course! Think about it. It's on the network layer, It is unique, and it's assigned to every device on the internet!
What is the highest layer of the OSI model used by router?
Router works in Network Layer of OSI model
Which device operate data link layer?
The Network Interface cards
Layer 1 problems that can interrupt network connectivity What three issues represent Layer 1 problems?
layer 1 deal with physical connectivity of network device.Most common problems related to Layer 1 as follow: -device power off -device power unplugged -loose network cable connection -incorrect cable type -faulty network cable
What facts are true when a device is moved from one network or subnet to another?
• The device will still operate at the same Layer 2 address.• The Layer 3 address must be reassigned to allow communications to the new network.
A repeater work at the physical and network layers. a. true b.false?
False - a repeater is a simple layer 1 device. It would not have a need to operate at the network layer.
Which device should be included in the network topology to provide Layer 2?
hub
What do you understand by broadcast network?
When a packet arrives at the network layer on the sender's device, it is encapsulated into a frame whose destination MAC address is all fs (FF-FF-FF...). The switch connected to the sender's device recognizes the all fs MAC address as a broadcast message and hence forwards it to all its ports.
Whic network layer device can separate anetwork into different broadcast domains?
ROUTER!
