Are you interviewing for a senior network engineer position? If yes, then you're at the right place. In this article, we've compiled the top 15 senior network engineer interview questions and answers to help you prepare for your upcoming interview.
As a senior network engineer, you must have experience working with both wide-area networks (WANs) and local-area networks (LANs). You should be able to explain the differences between the two and their architecture.
TCP (Transmission Control Protocol) is a reliable protocol used for data transmission between two devices. UDP (User Datagram Protocol), on the other hand, is used for transmitting data without establishing a connection.
DNS (Domain Name System) servers convert domain names (e.g., www.example.com) to their corresponding IP addresses. It functions to allow users to access websites with ease without having to remember IP addresses.
A VLAN (Virtual Local Area Network) is used to create a logical network segment within a physical network that allows you to group devices based on different configurations.
A switch connects multiple devices within a LAN and forwards data to the correct device. A router is used to connect two or more networks and forwards data between them.
NAT (Network Address Translation) is used to translate private IP addresses to public IP addresses to allow communication across the internet.
A VPN (Virtual Private Network) is used to create a secure connection between two devices over an unsecure network by establishing a private tunnel. It works by encrypting traffic between devices and hiding their IP addresses.
HTTP (Hypertext Transfer Protocol) is used to transmit data over the internet, while HTTPS (Hypertext Transfer Protocol Secure) encrypts the data using SSL (Secure Sockets Layer) to provide a secure connection.
SNMP (Simple Network Management Protocol) allows network administrators to monitor and manage network devices from a single management system.
Port forwarding is used to forward data packets sent to a specific port on a router to a specific device on the LAN.
QoS (Quality of Service) is used to ensure that specific types of network traffic receive priority over others to ensure a smooth network flow.
A subnet mask is used to divide IP addresses into subnets to allow devices within a network to communicate with each other.
Symmetric encryption uses a single key for encryption and decryption, while asymmetric encryption uses a public key for encryption and a private key for decryption.
Prepare and practice your answers to these questions to ace your senior network engineer interview! Good luck!
The role of a senior network engineer is critical in any organization.
