    What do you mean by network?

    • WAN

    Internetworking devices that are deployed in a network

    There are certain internetworking devices that are needed in order to connect Internet, namely:

    Hubs: It aids in extending the length of any cabling system in a network by just amplifying a signal followed by re-sending the signal that are in common multiport repeaters that are not related to data. The hub establishes connection between workstations followed by sending a signal to the workstations that are connected.

    NIC: It stands for Network Interface Card, which is nothing but a printed circuit board that is installed in various workstations. This works on the physical layer but is also considered in the data link layer. It helps in controlling the data transmission over the wire.

    Bridges: It is difficult to handle as the network keeps on widening. Thus, it is necessary to break down them into tinier LANs, which aids in monitoring the packets along with reducing the traffic. This also maintains a track of MAC addresses.

    Switches: Switches were designed to replace the bridges and are embellished for connecting multiple networks because of its swiftness. They are responsible for the transmission of information on independent networks.

    Routers: Router’s employed for directing data in the cost-effective route to destination, which operate at the third layer in order to communicate with the help of IP address instead of MAC address. They are capable of connecting different types of network like Ethernet, Token ring and FDDI.

    Brouters: They are nothing but a blend of bridge and routers and work as filters, which allows required data into the local network along with redirecting the unidentified data to others.

    MODEMs: This device enables the conversion of digital signals to analog signals through phone lines.

    TCP/IP layers

    Transmission control protocol/Internet Protocol decides on the establishment of connection of computer with Internet. In this TCP breaks down the data into small bundles whereas Internet Protocol addresses, sends along with receiving the bundles of data on the Internet.

    TCP/Internet Protocol Internet layer

    The overall communication over the Internet happens with the help of this protocol in small bundles. This layer consists of two activities:

    • Transmission of data to layers present in Network Interface
    • Routing of data to appropriate destinations

    The important protocols that are present in the transport layer are Transmission Control Protocol and User Datagram Protocol. Moreover, it is the reason for sequencing, along with acknowledgment of the already sent packet. These are also accountable for the process of recovery of data packets that are lost during the process of transmission.

    Network Segmentation

    This involves the splitting up of networks into various smaller networks, which improves the rate of the Internet. This can be accomplished by the following ways:

    • It is implemented by Demilitarised zone and gateway amidst various security requirements.
    • It can also be implemented by using domain isolation and server by deploying IP security.
    • By the implementation of storage based filtering along with segmentation by LUN.

    Why is Network Segmentation Essential

    Boost up Security- In order to protect against malicious cyber-attack, which can compromise the network usability. Moreover, for the detection and response to unknown intrusion prevailing in the specific network.

    Isolation of the network issues- It provides a faster pace in order to isolate the compromised device.

    Reduction in congestion- By fragmenting the LAN, count of hosts present in every network can be minimized to a large extent.

    Extension of network- Addition of routers is done in order to broaden the network.

    Segmentation in VLAN

    This enables the administrator to fragment the overall networks. Moreover, this segmentation is done after considering several factors like function, project team, or even application. A cluster of various devices that are related in VLAN serve on their network that is independent, even though they claim a typical infrastructure with the other VLANs that are used for data-link whereas the subnet is deployed for Network or IP layer.


    This process is to be considered as a base for hardware that is concerned about the address. Hence, is different from VLAN as they are based on software. Moreover, subnet is nothing but a cluster of Internet Protocol addresses. Points to be remembered during network segmentation are:

    • Appropriate authentication of users in order to access network segments in a secured manner.
    • ACL should be configured in an appropriate way.
    • Overall audit logs is accessed
    • Regular checking of devices, applications and packets should be done in order to make sure there is nothing, which interferes with security of the network.
    • There must always be a watch, always keeping an eye on outgoing and incoming traffic.

    Packet delivery process

    The process of packet delivery can be done in two different ways:

    • Packet bound for remote system on some other network.
    • Packet destined for the system on the very same network.

    Switch or MAC address can be deployed for the exchange of data when both sending and receiving devices are on the same network.

    CCNA Interview Questions

    The devices and the internet are used to complete the simple business processes and complex business functions. Coding is used to communicate with the devices with the required logic for the functions whereas network is used to connect the devices before the communication. Front end of the application deals with the data interaction, content and the design whereas the back end of the application deals with the server, database storage and the application functions. When dealing with the back end the knowledge about the programming language, network connection, and database system are the essential parts. Coding, networking, database management and data analysis are all inter-related terms in the big arena of the software industry.

    So, networking is part of coding also and programmers need to know about the networking basics. Hence the knowledge of the network and the support of technology are needed in our day to day activities. Here we provide the basic level and advance level interview questions for the CCNA students to win over in the race of the interviews by the employers. Join the CCNA Course in Chennai at FITA Academy to handle the complex and challenging tasks when enduring a job.

    • What do you infer by the word “Link”?

    The network used to connect two devices is called the link. Cables and protocols are the links used to connect two devices for the communication or connection.

    • List out the layers in the reference model of the OSI?

    Physical layer, network layer, session layer, transport layer, application layer, data link layer and the presentation layer are the 7 broad types of layers in the reference model.

    • Inscribe the term “Protocol”?

    Protocol is the set of rules to be followed to transfer the data of quantity from one system to another through network communication. CCNA Training in Chennai helps a heap group of students to get placed in big corporate companies.

    • Why is infrastructure called the backbone of the Network?

    Infrastructure of the network takes care of the routes and also handles the bandwidth with various channels for distribution of data. Hence the centralized infrastructure is referred to as the backbone for the networks.

    • What do you inscribe by the term switch in networking?

    In the OSI model, to produce a frame the switch is required. It shares the packets among the segments of the LAN. In the OSI model during the data transfer to the layer of the network or layer of the link the switch takes care of the packet control. The packets consist of the signal with the access to the destination address and share one frame to the desired frame with the help of the switches.

    • What is the meaning of ‘LAN’ in networking?

    LAN is the network connection used for a small area and it connects the computers and devices.

    • List out the differences among Hub, Routers and the switch?

    Switch is used to produce frames, share packets, controls the packet, and supports the single and multiple broadcast and collision domains. The router is used to handle two broadcast domains, it shares the data packets to the networks, the connection of the router is through the single LAN with IP address and with LAN or WAN. Hub is used to send things in the port to other places, it is used along with single domain for collision and single domain for broadcasting, and it is easy to use and available with less cost also. CCNA Course in Chennai gives the professional knowledge with an insight into the different job roles in the job market.

    • Explain the term node?

    Node is the place where the two computers or two devices are connected. To create a network connection two or more nodes are connected.

    • Describe the process in the point to point link?

    The connection through the NIC cards of the computers without network devices is called a point to point link.

    • How will you inscribe the term half duplex and full duplex in Networking?

    Half duplex is the one way communication whereas full duplex is two way communications. Example for the half duplex is the radio and the example for the full duplex is the cell phones.

    • What do you understand by the term network congestion?

    If the data with the node is huge then it leads to the loss of information or packets on the network. This is called network congestion. If this happens the user will not receive the exact data or information through the network.

    • What do you infer from the term subnet mask?

    The network address and the host address is identified by the IP address and subnet is also used along with the IP address to identify the address. Subnet consists of 32 bits.

    • Mention the size of a UTP cable?

    UTP cable with a single segment is 90 to 100 meters. This limit is not applicable for the switches and repeaters.

    • How will you describe the term data encapsulation?

    Before the data is transferred it is divided into smaller chunks and this process is known as encapsulation. The source and the address of the network destination are mentioned in the header after checking the parity. This process is called data encapsulation.

    • What do you inscribe by the term network topology?

    The map or the layout which consists of the connection among the computer network is called the network topology. CCNA Training in Chennai at FITA Academy helps the students to gain professional knowledge.

    • How do the three networks LAN, MAN and WAN differ?

    LAN is used for the local connection, MAN is the metropolitan network which is used for the wide area with buildings and WAN is the network within the organization. Several LANs are used under the WAN and it is the expensive connection with speed.

    • What are the different ways to transit the data in the networking?

    Simplex, full-duplex and half-duplex are the three ways to transit the data in the networking.
