Ques 19:- What is Trunk?

Trunks carry your multiple VLAN traffic in the network. Trunk Are Always configured on fast Ethernet port.

Ques 18:- What is the function of BPDU {Bridge Protocol Data Unit}?

BPDU Stands for Bridge protocol Data unit. It is basically used in spanning tree operation In the Network. It detects the looping in the Network.

Ques 17:- What is the function of Spanning Tree Protocol {STP}?

STP Stands for Spanning tree Protocol. It Stops the looping in the network

Ques 16:- What is Inter VLAN Routing?

Inter VLAN Routing provides the communication between two or more different VLAN in the Network. For Inter VLAN Routing we must have to require layer 3 device in the network.

Ques 15:- What is VLAN?

VLAN stands for Virtual Local Area Network it reduce the broadcasting in the network. With The Help Of VLAN We Can Create A Separate Broadcast Domain in The Switch.

Ques 14:- What is Collision Domain?

When Ever Two Computer Are Sending a Message to Each Other at a Same Time, Then Collision Will Be Happen, in that case we can Say Both Computer belongs to Single Collision Domain.
1. Hub Is a Single Collision Domain
2. Switch Is a Separate Collision Domain
3. Bridge is A Separate Collision Domain
4. Router Is a Separate Collision Domain

Ques 13:- What is Broadcast Domain?

When Ever one Computer Are Sending A Broadcast message in the Network And If Another Computer Receive That Broadcast message, in that Case We Can Say Both Computer Belongs To Single Broadcast Domain.
1. Hub Is a Single Broadcast Domain
2. Switch is a Single Broadcast Domain by Default
3. Router Is a Separate Broadcast Domain
4. Bridge Is a Single broadcast Domain By default.

Ques 12:- How Many Ports are available on the Router?

Generally there are five types of ports are available on the Router
1. Serial Port—Serial ports provides The Wan Connectivity
2. Ethernet Port—Ethernet ports provides the LAN Connectivity
3. Console Port—For Configuration Of Router, Switch, pix
4. BRI/PRI Port—ISDN Line Is Connected on this port
5. Auxiliary Port—Remotely Configuration of Router.

Ques 11:- What are the Difference between Fixed Router and Modular Router?

Fixed Router – we cannot add additional serial port as well as Ethernet port in this Router i.e. 2500 Series
Modular Router – we can add additional Serial port as well as Ethernet port in this Router i.e. 1600, 1700, 2600, 3600, 4500 and above Series.

Ques 10:- How many Types of Router are Available in the Network?

There are two types of Router in the Network
1. Fixed Router i.e. 2500 Series
2. Modular Router i.e. 1600, 1700, 2600, 3600, 4500 and above Series

Ques 9:- What is the function of Layer 3 Device?

Layer 3 Device provides the connectivity between two or more different Network ID as for example
1. Router
2. Layer 3 Switch

Ques 8:- What is the function of Layer 2 Device?

Layer 2 Device provides the connectivity within a single Network ID. As for example
1. Switch
2. Bridge

Ques 7:- What is the Function of Layer3 Switch?

Layer 3 Switch provides the connectivity between two or more different Network ID. It is basically use for Inter VLAN Routing in the Network.

Ques 6:- What is the function of Layer 2 Switch?

Layer 2 switch provides the connectivity within a single Network ID in the Network. There are two types of Layer 2 Switch
1. Normal Switch
2. Manageable Switch

Ques 5:- What is the Function of Router?

Router is a Device that provides the Connectivity between Tow and More Different Network ID. Router is a Layer 3 Device of OSI model.

Ques 4:- What is the Difference between Switch and Bridge?

Generally Switch and bridge are having the same functionality in the network but there is one major difference between switch and bridge.

Bridge maximum 16 ports are available
Switch – Maximum 100 ports are available

Ques 3:- How many types of Switch?

There are two types of switch
1. Normal Switch
2. Manageable Switch

Ques 2:- What is the Between Normal Switch and Manageable Switch?

Normal Switch – we cannot configure normal switch that means we cannot create VLAN in this Switch. with the help of this switch we cannot create a separate broadcast domain in the network

Manageable Switch – we can configure Manageable switch that means we can create VLAN in this Switch. with the help of this switch we can create a separate broadcast domain in the network

Ques 1:- What is the Difference between Hub and Switch?

HUB
1. Hub is a Layer 1 Device
2. Hub is not more intelligent device
3. Hub does not reads the frame
4. Hub provides the always broadcasting in the network
5. we cannot configure Hub
6. In Hub the rate of data transmission is slow
7. hub is a half duplex device
8. the rate of data transmission is divided in hub
9. hub does not provide packet filtering in the network
10. hub is a single broadcast domain
11. hub is a single collision domain
12. Hub does not create any table
SWITCH
1. Generally Switch is a Layer 2/ Layer 3 Device
2. Switch is a more intelligent device
3. Switch reads the frame
4. Switch provides conditional broadcasting in the network
5. we can configure Switch
6. In Switch the rate of data transmission is fast
7. Switch is a full duplex device
8. the rate of data transmission is not divided in Switch
9. Switch provide packet filtering in the network
10. Switch is a single broadcast domain (By default)
11. Switch is a separate collision domain
12. Switch creates a table that Table is called switching table
