Mentor Infocomm India Private Limited Network Support Engineer Interview Questions and Answers

TCP is on the transport layer (Layer 4) and UDP is also on the transport layer (Layer 4).

• TCP is a connection-oriented protocol that provides reliable data delivery. It operates on the transport layer (Layer 4) of the OSI model.

• UDP is a connectionless protocol that provides faster data transmission but without guaranteed delivery. It also operates on the transport layer (Layer 4) of the OSI model.

The OSI (Open Systems Interconnection) model is a conceptual framework that standardizes the functions of a telecommunication or computing system into seven abstraction layers.

• The OSI model helps in understanding how data is transmitted over a network.

• It starts from the physical layer (Layer 1) which deals with the actual physical connection between devices.

• Each layer has specific functions and protocols, such as TCP/I...read more

• LTE module is a small hardware component that allows devices to connect to LTE networks.

• It is commonly used in smartphones, tablets, and other mobile devices.

• LTE modules support high-speed wireless communication for faster data transfer.

• Examples of LTE modules include Quectel LTE modules, Sierra Wire

Load balancing is the process of distributing network traffic across multiple servers to ensure optimal resource utilization and prevent overload.

• Use a load balancer to evenly distribute incoming traffic to multiple servers

• Implement algorithms like round-robin, least connections, or IP hash for load balancing

• Monitor server health and adjust traffic distribution accordingly

• Ensure high availability and scalability by add

Networking is the practice of connecting computers and other devices to share resources and information.

• Networking involves the physical connection of devices through cables or wireless connections.

• It also includes the configuration of network settings to enable communication between devices.

• Networking allows for sharing of resources such as files, printers, and internet connections.

• Examples of networking technologies ...read more

OSI layers refer to the Open Systems Interconnection model, which is a conceptual framework that standardizes the functions of a telecommunication or computing system into seven distinct layers.

• The OSI model consists of seven layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application.

• Each layer has specific functions and interacts with adjacent layers to facilitate communication between dev...read more

MPLS is a protocol used in telecommunications for efficient packet forwarding. Layer 1 troubleshooting involves physical connectivity issues. Routing involves determining the best path for data packets. Switching involves forwarding data packets within a network.

• MPLS (Multiprotocol Label Switching) is a protocol used to efficiently route data packets within a network.

• Layer 1 troubleshooting involves identifying and res...read more
