Network Support Engineer, Associate Network Engineer, Engineer Network Operations Interview Questions and Answers

As an engineer, my positivity lies in my problem-solving skills and ability to adapt to new technologies. My negativity is my impatience with inefficiencies and lack of attention to detail.

• Positivity: Strong problem-solving skills

• Positivity: Adaptability to new technologies

• Negativity: Impatience with inefficiencies

• Negativity: Lack of attention to detail

Packet flow is the movement of data packets from one network device to another.

• Packet flow starts when a user sends data packets to a network device.

• The device then checks the destination address and forwards the packet to the next device in the path.

• This process continues until the packet reaches its destination user.

• Packet flow can be affected by network congestion, routing issues, and other factors.

• Protocols like TCP and UDP help ensure reliable packet delivery.

• Packet flow...read more

IPv6 has a larger address space, improved security, and simplified header compared to IPv4.

• IPv4 uses 32-bit addresses while IPv6 uses 128-bit addresses

• IPv6 has a simplified header with fewer fields compared to IPv4

• IPv6 has built-in security features such as IPsec

• IPv6 supports multicast traffic more efficiently than IPv4

• IPv6 allows for more efficient routing and network auto-configuration

• IPv6 addresses are written in hexadecimal notation separated by colons, while IPv4 address...read more

OSPF is a link-state routing protocol used to determine the shortest path for data packets in a network.

• OSPF routers exchange link-state advertisements (LSAs) to build a topology map of the network.

• Each router calculates the shortest path tree (SPT) based on the topology map.

• OSPF uses cost as the metric to determine the shortest path.

• The cost is calculated based on the bandwidth of the link.

• OSPF supports multiple areas to reduce the size of the topology map and improve scalab...read more

Bandwidth refers to the amount of data that can be transmitted over a network connection in a given amount of time.

• Bandwidth is measured in bits per second (bps)

• Higher bandwidth means faster data transfer rates

• Bandwidth can be limited by network congestion or physical limitations

• Bandwidth is important for streaming video, online gaming, and other data-intensive applications

A node is a point of connection within a network that can send, receive, or forward data packets.

• Nodes can be devices such as computers, routers, switches, or servers.

• Nodes can also be virtual entities such as virtual machines or containers.

• Nodes can communicate with each other through various protocols such as TCP/IP or UDP.

• Nodes can be organized into different topologies such as star, mesh, or ring.

• Nodes can have different roles within a network such as client, server, or g...read more

There are six network topologies: Bus, Star, Ring, Mesh, Tree, and Hybrid.

• Bus topology connects all devices in a linear sequence.

• Star topology connects all devices to a central hub or switch.

• Ring topology connects all devices in a circular loop.

• Mesh topology connects all devices to each other directly.

• Tree topology connects multiple star topologies in a hierarchical structure.

• Hybrid topology combines two or more topologies.
