142 Network Engineer Questions And Answers
102⟩ Tell me what is SLIP (Serial Line Interface Protocol) in network engineering?
It is a very simple protocol used for transmission of IP data-grams across a serial line.
103⟩ Tell me have you ever worked in heterogeneous environments and multiple server and client platforms?
The obvious answer to this question is yes or no, but you should elaborate if the answer is yes. Most networking environments use a combination of Windows and Linux servers and desktops. Usually, network engineers prefer Linux servers and work with Windows and Linux desktops. Occasionally, you might have some Mac desktops as well to work with.
104⟩ What is cladding in network engineering?
A layer of a glass surrounding the center fiber of glass inside a fiber-optic cable.
105⟩ What is point-to-point protocol in network engineer?
A communications protocol used to connect computers to remote networking services including Internet service providers.
106⟩ What is gateway in network engineering?
A gateway operates at the upper levels of the OSI model and translates information between two completely different network architectures or data formats.
107⟩ What is attenuation in network engineering?
The degeneration of a signal over distance on a network cable is called attenuation.
108⟩ Can you please explain the difference between TFTP and FTP application layer protocols?
The Trivial File Transfer Protocol (TFTP) allows a local host to obtain files from a remote host but does not provide reliability or security. It uses the fundamental packet delivery services offered by UDP.
The File Transfer Protocol (FTP) is the standard mechanism provided by TCP / IP for copying a file from one host to another. It uses the services offer by TCP and so is reliable and secure. It establishes two connections (virtual circuits) between the hosts, one for data transfer and another for control information.
109⟩ List the important topologies for networks?
☛ BUS topology: In this each computer is directly connected to primary network cable in a single line.
☷ Advantages: Inexpensive, easy to install, simple to understand, easy to extend.
☛ STAR topology: In this all computers are connected using a central hub.
☷ Advantages: Can be inexpensive, easy to install and reconfigure and easy to trouble shoot physical problems.
☛ RING topology: In this all computers are connected in loop.
☷ Advantages: All computers have equal access to network media, installation can be simple, and signal does not degrade as much as in other topologies because each computer regenerates it.
110⟩ Explain the major types of networks?
☛ Server-based network: provide centralized control of network resources and rely on server computers to provide security and network administration
☛ Peer-to-peer network: computers can act as both servers sharing resources and as clients using the resources.
111⟩ Describe the mesh network?
A network in which there are multiple network links between computers to provide multiple paths for data to travel.
112⟩ Can you please explain the difference between baseband and broadband transmission?
In a base-band transmission, the entire bandwidth of the cable is consumed by a single signal. In broadband transmission, signals are sent on multiple frequencies, allowing multiple signals to be sent simultaneously.
113⟩ What is 5-4-3 rule in network engineering?
In a Ethernet network, between any two points on the network ,there can be no more than five network segments or four repeaters, and of those five segments only three of segments can be populated.
114⟩ What is MAU in network engineering?
In token Ring , hub is called Multistation Access Unit(MAU).
115⟩ Do you know about some basic ways to speed up network performance?
There are several ways to improve network performance. You can first make sure you disable peer-to-peer downloading and torrents. Some companies restrict media streaming such as YouTube and Pandora. You can also add compression to files to reduce the amount of bandwidth used. Another area where some network admins make mistakes is timed backups and large data transfers. Make sure your backups are done during slow network times, which is usually overnight when the office is closed.
116⟩ Why should one care about the OSI Reference Model?
Because it provides a framework for discussing network operations and design.
117⟩ Can you please explain the difference between routable and non- routable protocols?
Routable protocols can work with a router and can be used to build large networks. Non-Routable protocols are designed to work on small, local networks and cannot be used with a router.
118⟩ What is logical link control in network engineering?
One of two sub-layers of the data link layer of OSI reference model, as defined by the IEEE 802 standard. This sub-layer is responsible for maintaining the link between computers when they are sending data across the physical network connection.
119⟩ Tell me about silly window syndrome?
It is a problem that can ruin TCP performance. This problem occurs when data are passed to the sending TCP entity in large blocks, but an interactive application on the receiving side reads 1 byte at a time.
120⟩ What is virtual path in network engineering?
Along any transmission path from a given source to a given destination, a group of virtual circuits can be grouped together into what is called path.
