What are the top Network Engineer skills required to excel in IT?
The top Network Engineer skills required to excel in IT are as follows-
Network Fundamentals
What are the basic principles of networking?
The basic principles of networking are routers, switches, and wireless access points since they help in seamless communication between diverse devices.
How do network topologies function?
Network topologies provide insight into the network by visualizing the physical connection of devices and the data flow within the network.
What are the OSI and TCP/IP models?
OSI model refers to the Open System Interconnection model. It enables diverse communication systems to communicate via standard protocols.
TCP/IP models refer to Transmission Control Protocol and Internet Protocol. These are used to interconnect network devices.
Network Protocols
What are the common network protocols?
There are mainly three types of network protocols, namely-
> Network Communication Protocol: NCPs determine the rules and formats to transfer data across the networks. A few NCPs are as follows-
- Hyper-Text Transfer Protocol (HTTP)
- Transmission Control Protocol (TCP)
- Internet Protocol (IP)
- User Datagram Protocol (UDP)
- File Transfer Protocol (FTP)
> Network Security Protocol: NSPs ensure secure data transmission over the network connections. A few NSPs are as follows-
- Secure File Transfer Protocol (SFTP)
- Hyper-Text Transfer Protocol Secure (HTTPS)
- Secure Socket Layer (SSL)
> Network Management Protocol: NMPs ensure quick troubleshooting across the network. A few NMPs are as follows-
- Simple Network Management Protocol (SNMP)
- Internet Control Message Protocol (ICMP)
How do protocols like TCP, UDP, and ICMP function within a network?
TCP is a reliable protocol but has a slow speed and is more complex than UDP.
UDP is fast and simple, but less reliable and more prone to errors than TCP.
ICMP is used for network management and troubleshooting.
What are the differences between IPv4 and IPv6?
IPv4 uses 32-bit addresses, while IPv6 uses 128-bit addresses, allowing for vastly more unique addresses in IPv6.
Routing and Switching
What is the role of routers and switches in a network?
Routers determine the best path for data to travel between networks, while switches direct data within a single network.
How do routing protocols such as OSPF, BGP, and EIGRP operate?
BGP is a networking protocol that exchanges routing data among autonomous systems.
OSPF is a link-state routing protocol to find the optimum path between the source and the destination router.
EIGRP is a distance-vector protocol for automating routing configuration and decisions on a network.
What are VLANs, and how do they enhance network efficiency?
VLANs manage network traffic by dividing the network into different broadcast domains. This ensures broadcast traffic is only sent to devices in the same VLAN, reducing unnecessary load and refining overall network performance. Enhanced security.
Network Security
What are the fundamental principles of network security?
The fundamental principles of network security are as follows-
- Defense in Depth
- Least Privilege
- Principle of Least Astonishment
- Separation of Duties
- Access Control
- Secure Configuration
- Confidentiality
- Integrity
- Availability
- Authentication and Authorization
What are common security threats?
The most common security threats are as follows-
- Malware
- Phishing
- DDoS Attacks (Distributed Denial of Service)
- Ransomware
- Insider Threats
- Man-in-the-Middle Attacks
- SQL Injection
- Cross-Site Scripting (XSS)
- Zero-Day Exploits
- Social Engineering
Network Automation
What is network automation?
Network automation refers to the process of automating the configuration, management, and operation of network devices and infrastructure. It involves using software tools and scripts to streamline repetitive tasks, improve efficiency, and enhance network reliability. Network automation enables faster deployment, better scalability, and more agile responses to changing network requirements.
How can automation streamline network configuration, management, and troubleshooting?
Automation can streamline network configuration, management, and troubleshooting. A few of the features are as follows-
- Automation can deploy network configurations across multiple devices, reducing the time and effort required for manual setup.
- Automated processes ensure uniformity in network configurations.
- Automation scales easily to manage large and complex networks.
- Automated monitoring and diagnostic tools can quickly identify and rectify network issues.
- By automating routine tasks, network engineers can focus on strategic planning, innovation, and addressing more complex challenges.
