Juniper Network Interview Questions and Answers 

1. What do you mean by a Network and how they are important?

A network is basically nothing but an interconnection of computers or computing devices. In a network, they are called nodes. Networking is crucial because it enables easy file sharing, transport, and modifying from any node on a network. Data can be on any node and depending on the security and other concerns, early nodes can be permitted to access it anytime. Networking doesn ’ deoxythymidine monophosphate impose a restrict on the distance between two nodes .

2. What are the types of Networks you are familiar with?

There are three types of Networks that presently exist and they are :
LAN:  It Stands for Local Area Network and is broadly an interconnection of a limited number of nodes which can be within a build or an constitution.
MAN: Man stands for Metropolitan Area Networks. The combination of diverse Local Area Networks is known as Metropolitan Area Networks. Generally, the nodes within a city are connected with each other and it is called MAN.
WAN: It abbreviates for Wide Area Network. The combination of all the MANs ’ or all the nodes across the globe is broadly regarded as WAN. The other name of WAN is the internet .

It actually defines the connection between two or more network or computing devices. broadly, the channels and the protocols which control the communication or made it possible among the nodes are regarded as links. The size of the associate is not constantly necessary to be the same for all the networks. It depends on the type and the number of devices in a network.

4. What do you know about the OSI reference model? Can you name the layers present in it?

OSI abbreviates for Open-System-Interconnection and is actually a network model. Although it is an previous overture, there are still many networks that are based on it. There are sum 7 seven layers that are present in it and they are :
Application Layer
Presentation Layer
Session Layer
Transport Layer
Network Layer
Data Link Layer
Physical layer

5. In networking, how you will define a server?

It is basically a herculean calculator in a network that manages and controls all the devices on a network. basically, it ’ sulfur nothing but a server that processes the data centrally and makes the data transplant and communication possible among all early nodes. If a waiter fails, it can result in the failure of the entire network .

6. Name the first and the last layer in an OSI reference model?

The first layer besides known as the bed layer is the Physical Layer and the last layer which is besides known as the top layer is the Application Layer .

7. What exactly do you mean by a backbone network?

It is basically a network that is responsible for assigning the data and the path to different networks. Monitoring the channels, protocols, and bandwidth management is besides the duty of a spine net. It is because of this reason it has been named as a anchor network .

8. Name a device that will help you to connect multiple devices on a network with limited bandwidth or with limited channels?

The throw is a network device that can be used in such a scenario. A switch can be of any size depending on the needs .

9. In data encapsulation, how each chunk knows about its destination?

basically, data encapsulation is an approach in which the data is divided into smaller packets called chunks. All chunks have their source and address address on them and this is how they reach their finish. It is necessity for network security that the collocate must contain its source address besides .

10. Name a few networking devices you are familiar with?

1. Hub, Router
2. Modem
3. Switch
4. Repeater
5. Bridge
6. network interface

11. In a network, is it always necessary to have a server for controlling other devices?

No, a network can be established without a server excessively. This character of network or model is called a peer-to-peer model. Basically, all the nodes act as a client deoxyadenosine monophosphate well as a server for the other nodes. The biggest advantage is the failure of one node doesn ’ triiodothyronine impact other nodes on a network and helps to maintain continuous operations .

12. In a network, what do you mean by a router?

A router is basically a network device that is basically deployed for connecting the network segments which is actually very important. There are paths in the routers which are used for data storage and because of this rationality they are called intelligent network devices. It is actually the duty of the router to select and define the best path for the data that needs to be transferred .

13. In networking, what exactly the term topology means?

Topology defines how the computers on a network are connected with each other. It is actually potential to connect them in different manners. The interconnection method acting largely matters as it can affect diverse factors such as data transmission focal ratio, troubleshooting methods, and so on .

A point-to-point connect is nothing but a mastermind path for information or data transfer between two defined nodes in a network. A childlike case of point to point associate is nothing but connecting two computers with each other simply by using a cable that is inserted in the Network Interface Cards in both the computers. This kind of connection is created entirely in a few computers on a net. Although it enhances the monetary value and network cost, it assures excellent data transfer travel rapidly and is by and large free from any form of glitches .

15. Name the layers which are present in the TCP/IP model?

These are :

1. Networking Layer
2. Internet Layer
3. Transport Layer
4. Application Layer
It ’ s not that Data Link Layer, Session Layer, and Physical Layer are absent in this model but they are merged with the above layers. TCP/IP stands for Transmission Control Protocol/ Internet Protocol and is the normally use model in the salute scenario .

16. What do you understand by the term FTP?

It abbreviates for File Transfer Protocol and is broadly a method of allowing permission to the users for accessing data. All the users which are allowed to access the data need not to prove their identity again and again. They can access data with the username and passwords assigned to them .

17. Suggest one method that you will use for increasing the security of a file or data on a network that contains some confidential information?

It is potential to apply assorted restrictions on such data or files. For exercise, only a limited number of users can be allowed to access the same, and not all of them .

18. Suppose you are connecting devices with a cable to establish a connection, what would be the general limit on the distance that two computers can have with such an approach. Is it possible to extend this limit somehow?

well, the cosmopolitan limit on the length of cable used in connecting two computers in a net is up to 100 meters. This terminus ad quem can be increased by using the switches and signal repeaters .

19. Name the layer in the OSI model which is responsible for Packet Switching and data routing?

It is the responsibility of the Network Layer. The Network Layer is the number 3 layer from the bottom in an OSI reference point model .

20. Why security to a network is important? How this can be done?

A net obviously contains the personal information of the users or something that is identical confidential for the implicated organizations. There are many unauthorized attempts that can be made by hackers to steal such information. For exercise, the future plan of one company can be leaked to its competitors who can take advantage of the like in advance. therefore securing a network is important. This can be done by using Network Firewall, Antivirus software, imposing limits on data, and through several other approaches .

21. Name one approach that you will apply for continuous data availability?

Fault Tolerance System

22. What is the significance of Proxy Servers in a network?

well, Proxy servers are the flower contributors to guard. The fact is there can be certain attempts by external users to access the datum on a node that is registered on a network. The proxy waiter doesn ’ metric ton let them trace the demand location of a node as it reflects an incorrect IP address. It is extremely difficult for any drug user to access data without knowing the IP address. frankincense, it contributes to the safety of a network. It is besides possible to hide a node from a network with this approach .

23. What makes nodes or devices on a network recognizable and different from each other?

Each node or device on a network has a network address in numbers which is normally called its IP. The IP provides all such information about a lymph node or a device on a network. The IP is unique and can not be the lapp for two nodes on a network. It provides all the information about the node such as its location, registered drug user, and so on .

24. What is the cross-talk problem in a network and how it can be avoided?

crosstalk is nothing but a position when the signal has electromagnetic interferences. It can impose a limit or can largely affect data during its transmission. For eliminating this situation, the cables used are shielded. The shield is actually a traverse on the cable which doesn ’ thymine let it face this problem. crosstalk problem broadly declares its presence during the voice signal infection .

25. Why star topology is not to be considered in a network?

In headliner topology, all the computers or devices are connected to a individual hub which is responsible to control the lapp. The price or the failure to the hub can make the entire network useless. Therefore this approach is not so common in the present scenario .

26. What do you mean by network troubleshooting? Can you suggest some ways for the same?

inspection of a network thoroughly and then taking appropriate actions against the facts that can shortly lead to big issues if ignored is considered as network troubleshooting. Most of the prison term, it ’ s the channels or the network devices that connect the nodes in a network that needs to be paid attention to for this. The trouble-shoot procedure depends on the size and type of the network and it can not be the same for all the networks .

27. Is it possible to connect a public network to a private network?

Yes, it is potential and generally, the default gateway protocol is followed for this. Connecting both these networks with each other is quite common. private Networks are besides called Intranets and are deployed where more security and faster amphetamine are required.

28. What can be the common problems in a network?

1. Issues that are related to policies
2. Bandwidth problems
3. mismatch of protocols
4. client Server problems
5. IP mismatch
6. Improper Configuration
7. security concerns

29. Why are Fiber Optics cables preferred in networks?

There are actually sealed benefits these cables can have. Although their cost is high, they can bring a full bouquet of pros with them. One of the leading benefits is they support larger bandwidth which makes indisputable of bulk data transmission in a short time couple. The craved rate for the Signal-to-Noise proportion can be achieved. besides, at the same time errors and problems related to crosstalk can plainly be avoided .

30. What is clustering support and how does it matter?

basically, the bunch overture is nothing but the ability of an manoeuver arrangement to support multiple servers. This is to make indisputable of network or the node working during an hand brake situation such as the waiter or the might failure .
