Network Support Engineer Interview Questions and Answers for Freshers

Configuring telnet and ssh, understanding OSI module and DHCP

• To configure telnet, enable the telnet service on the device and set a password for access

• To configure ssh, generate a public and private key pair and enable ssh service on the device

• OSI module is a conceptual model that describes how data is transmitted over a network

• DHCP is a protocol that automatically assigns IP addresses to devices on a network

Router configurations involve setting up and managing network devices to ensure efficient and secure communication.

• Router configurations involve configuring IP addresses, subnet masks, and default gateways.

• Setting up access control lists (ACLs) to control network traffic.

• Enabling routing protocols such as OSPF or BGP for dynamic routing.

• Configuring NAT (Network Address Translation) to allow private IP addresses to access the internet.

• Implementing security measures like firewa...read more

Python language supports various data structures and algorithms concepts.

• Python has built-in data structures like lists, tuples, dictionaries, and sets.

• Common algorithms like sorting (e.g. merge sort, quick sort) and searching (e.g. binary search) can be implemented in Python.

• Python also supports advanced data structures like stacks, queues, heaps, and graphs.

• Popular libraries like NumPy and Pandas provide efficient data structures for numerical computations and data manipula...read more

An IP address is a unique numerical identifier assigned to each device connected to a computer network.

• IP stands for Internet Protocol

• It consists of four sets of numbers separated by dots

• It is used to identify and communicate with devices on a network

• IPv4 addresses are 32-bit and IPv6 addresses are 128-bit

• Example: 192.168.1.1

The OSI model is a conceptual model that characterizes and standardizes the communication functions of a telecommunication or computing system.

• OSI stands for Open Systems Interconnection.

• It has 7 layers, each with a specific function.

• The layers are: Physical, Data Link, Network, Transport, Session, Presentation, and Application.

• Each layer communicates with the layer above and below it.

• The model helps ensure interoperability between different systems and devices.

• Example: HTTP ...read more
