Q1. Ethernet uses how many bit/byte physical address, that is imprinted on the network interface card?

64 bit

64 byte

6 bit

6 byte

32 bit

Solution:

Ethernet uses a 6 -byte (48-bit) physical address that is imprinted on the network interface card (NIC). The physical address also known as the link address is the address of a node physical address, also known as the link address, is the address of a node as defined by its LAN or WAN. It is included in the frame used by the data link layer.

Q2. Which type of security attack occurs, when a malicious actor inserts himself as a relay/proxy into a communication session between people or systems?

Compromised key attack

Sniffer Attack

Man-in-the-Middle attack

Denial-of-service attack

Eavesdropping

Solution:

A man-in-the-middle attack is a type of cyberattack where a malicious actor inserts him/herself into a conversation between two parties, impersonates both parties and gains access to information that the two parties were trying to send to each other. A man-in-the-middle attack allows a malicious actor to intercept, send and receive data meant for someone else, or not meant to be sent at all, without either outside party knowing until it is too late.

Q3. Which protocols is used to monitor network devices such as hubs, switches, and routes?

SMTP

RIP

SNMP

OSPF

HTTP

Solution:

Simple Network Management Protocol (SNMP) is a popular protocol for network management. It is used for collecting information from, and configuring, network devices, such as servers, printers, hubs, switches, and routers on an Internet Protocol (IP) network.

Q4. Which of the following is not the major function of PKI?

Confidentiality

Accessibility

Authentication

Integrity

Non-Repudiation

Solution:

The Public Key Infrastructure (PKI) is a set of hardware, software, people, policies, and procedures needed to create, manage, store, distribute, and revoke Digital Certificates. A Public Key Infrastructure (PKI) enables users of a basically unsecure public network such as the Internet to securely and privately exchange data using a public and a private cryptographic key pair that is obtained and shared through a trusted authority. There are 4 major function of Public Key Infrastructure (PKI): Confidentiality, Authentication, Integrity, Non-Repudiation.

Q5. Which class of IP address provides a maximum of only 254 host addresses per network ID?

A Class

B Class

C Class

D Class

E Class

Solution:

Class C network address only has 8 bits for defining hosts.

Q6. PPP used in which layer of network reference model?

Physical layer

Data link layer

Network layer

Application layer

Presentation layer

Solution:

Point-to-Point Protocol (PPP) is a data link layer (layer 2) communications protocol used to establish a direct connection between two nodes. It connects two routers directly without any host or any other networking device in between. It can provide connection authentication transmission encryption and compression.

Q7. What is SSH?

Routing Protocol

Connection mechanism

Network Model

Cryptographic Protocol

Connector

Solution:

SSH (Secure Shell) is cryptographic a protocol which define how to connect securely over a network. SSH (Secure Shell) protocol provides the three main ideas of security authentication, confidentiality (via encryption) and integrity of data transfer over a network. SSH supports Authentication to reliably determine the identity of the connecting computer, encryption to scramble data so that only the intended recipient only can read it and Integrity to guarantees the data sent over the network is not changed by a third party.

Q8. Which of the following is the process of splitting a message into multiple packets at transport layer?

Fragmentation

Segmentation

Synchronization

Defragmentation

Framing

Solution:

packet segmentation is the process of dividing a data packet into smaller units for transmission over the network.

Q9. An accountant office has four employees. They have four computers and two printers. What kind of network would you suggest they install?

Client server network

Peer-to peer network

Intranet

MAN

None of the above

Solution:

A peer-to-peer (P2P) network is group of computers, each of which acts as a node for sharing files within the group. Instead of having a central server to act as a shared drive, each computer acts as the server for the files stored upon it.

Q10. End-to-end connectivity is provided from host-to-host in which layer?

Network layer

Session layer

Data link layer

Transport layer

Presentation layer

Solution:

The transport layer is the layer in the open system interconnection (OSI) model responsible for end-to-end communication over a network. It provides logical communication between application processes running on different hosts within a layered architecture of protocols and other network components. The transport layer is also responsible for the management of error correction, providing quality and reliability to the end user. This layer enables the host to send and receive error corrected data, packets or messages over a network and is the network component that allows multiplexing.

Q11. IP address 128.167.152.2 is belongs to which class?

None

Solution:

Range of Class B address is 128.0.0.0 to 191.255.255.255

Q12. An administrator attempts a traceroute but receives a “Destination Unreachable” message. Which protocol is responsible for that message?

RARP

RUDP

ICMP

SNMP

ARP

Solution:

The ICMP destination unreachable message is generated by a router (which is reachable) to inform the source host that the destination unicast address is unreachable.

Q13. Which type of network consists set of switches connected by physical links?

Circuit Switched Network

Datagram Network

Virtual Circuit Network

All of these

None of these

Solution:

In Circuit-switched networks, a physical path is dedicated to a single connection between two end-points in the network for the duration of the connection.

Q14. Which of the following layer oversees both error control & flow control at the source to destination level?

Physical

Data link

Transport

Network

None of these

Solution:

The transport layer in a network model is responsible for process-to-process delivery of the entire message. The transport layer in a network model, ensures that the whole message arrives intact and in order, overseeing both error control and flow control at the source-to-destination level.

Q15. Bridge work at which layer of OSI Model?

network layer

Data link layer

Physical layer

application layer

Transport layer

Solution:

Bridges operate at the Data-Link Layer of the OSI Model. They can distinguish between local and remote data, so data traveling from one workstation to another in the same segment doesn't have to cross the bridge. Bridges operate on MAC-Layer addresses.
