➤ In this page provides you Network Devices Multiple Choice Question With Answer. In this MCQ Sets is very useful of many Exam like Semester ,ISRO, DRDO ,Banking ,Railway
Q.1 Which of the devices that is used to build and interconnect network?
Repeater
Gateway
Switch
All of the above
Explanation
Networking devices like repeaters, gateways, and switches are all used to build, extend, and connect different parts of a network.
Q.2 Which of the following Device is Maintain IP Address?
Router
Gateway
Switch
All of the above
Explanation
Routers operate at the Network Layer (Layer 3) and use IP addresses to determine the best path for data packets.
Q.3 A Device that connects networks with different protocols?
Router
Gateway
Switch
All of the above
Explanation
A Gateway acts as a protocol converter, allowing communication between networks that use entirely different architectures and protocols.
Q.4 Which of the following Device is used to Boost up the Weak Signals?
Router
Gateway
Repeater
None of these
Explanation
A Repeater receives a signal and retransmits it at a higher level or higher power so that the signal can cover longer distances.
Q.5 Which of the following Device is used to connect similar Protocols?
ISDN
Dial-Up
Bridges
None of these
Explanation
Bridges are used to connect two separate LAN segments that use the same protocol, effectively making them act as a single network.
Q.6 Which of the following Device is used to connect one LAN to other LAN Using Same protocol?
Switch
Router
Bridges
None of these
Explanation
A Switch is commonly used to connect multiple devices or LAN segments using the same protocol to facilitate communication within a network.
Q.7 Repeater operates in which layer of the OSI Model?
Physical Layer
Network Layer
Transport Layer
Application Layer
Explanation
Repeaters work at the Physical Layer (Layer 1) as they only deal with bits and electrical/optical signals without looking at addresses.
Q.8 Which of the following device is used to send the message is Secure?
Bridge
Switch
Hub
None of these
Explanation
A Switch is more secure than a Hub because it sends data only to the specific destination port (unicast) rather than broadcasting it to everyone.
Q.9 ——— is generally used to Unicast the message?
Bridge
Switch
Hub
None of these
Explanation
Unlike a Hub which broadcasts data to all ports, a Switch uses MAC addresses to unicast messages directly to the intended recipient.
Q.10 Which is not the strategies of Switch?
Storage & Forward Switch
Store & Backward Switch
Store & Send
None of these
Explanation
Store & Backward’ is not a standard switching technique; common methods include Store-and-Forward and Cut-Through.
Q.11 ——- is a Network device which works as a traffic controller?
Bridge
Switch
Router
None of these
Explanation
Routers act as traffic controllers by managing data flow between different networks and choosing the most efficient paths.
Q.12 Router Works Under the —— of OSI Model?
Application Layer
Network Layer
Physical Layer
None of these
Explanation
Routers function at the Network Layer (Layer 3) of the OSI model to handle routing and logical addressing (IP).
Q.13 Transmission Mode of HUB?
Full Duplex
Simplex
Half Duplex
All of the above
Explanation
Hubs operate in Half Duplex mode, meaning they can either send or receive data, but not both at the same time, leading to potential collisions.
Q.14 The data speed of HUB?
10Mbps
5Mbps
20Mbps
None of these
Explanation
Traditional standard Ethernet hubs typically operate at a speed of 10Mbps.
Q.15 In which of the following device is used to connect totally dissimilar type of network?
HUB
Gateway
Bridge
None of these
Explanation
Gateways are specifically designed to bridge the gap between two networks that are built on entirely different technologies and protocols.
Q.16 A Three layer switch is a kind?
HUB
Repeater
None of these
Explanation
A Layer 3 switch combines the functionality of a switch and a router, allowing it to route data based on IP addresses.
Q.17 Which of the following Device is operates in all seven layers of OSI Model?
Gateway
Repeater
Router
None of these
Explanation
Gateways are high-level devices that can operate across all seven layers of the OSI model to perform complex protocol translations.
Q.18 A Gateway is also known as?
Router
Repeater
Firewall
None of these
Explanation
In many network architectures, the gateway serves as the security checkpoint or Firewall for the internal network.
Q.19 The central connection point of a star network?
HUB
Repeater
Firewall
None of these
Explanation
In a Star topology, all individual nodes are connected to a central device, which is typically a Hub or a Switch.
Q.20 A device that can used to convert digital signals to analog signals is?
Router
Repeater
Modem
None of these
Explanation
A Modem (Modulator-Demodulator) converts digital signals from a computer into analog signals for transmission over telephone lines, and vice versa.
