Study Notes
Networking Fundamentals
- Compare and contrast the OSI model layers, emphasizing the role of encapsulation in data transmission.
- Understand different network topologies (like star, mesh, bus) and types (LAN, WAN, MAN), including their characteristics and use cases.
- Identify various types of cables (Ethernet, fiber optic, coaxial) and connectors (RJ-45, LC, SC), and choose the appropriate ones for specific networking needs.
- Ability to configure a subnet, implementing correct IP addressing schemes to manage network resources effectively.
- Explain common network ports (like HTTP on port 80, HTTPS on port 443) and protocols, including their secure alternatives (e.g., SFTP for FTP).
- Understand the purpose and function of essential network services (DNS, DHCP) in maintaining communication and resource management.
- Describe basic corporate and data center network architectures, addressing design and scalability factors.
- Remember key concepts of cloud computing, including deployment models (public, private, hybrid) and connectivity options (VPNs, direct access).
Network Implementations
- Analyze various networking devices (routers, switches, firewalls) and assess their features and optimal placement within a network.
- Compare different routing technologies (static vs. dynamic routing) and evaluate bandwidth management concepts (QoS, traffic shaping).
- Practice configuring and deploying fundamental Ethernet switching features like VLANs and port security for enhanced network performance.
- Install and configure suitable wireless standards (802.11a/b/g/n/ac/ax) to ensure effective wireless communication and performance.
Network Operations
- Apply the use of network statistics and sensors (SNMP, logs) to monitor and ensure network availability effectively.
- Understand the importance of organizational documents (network diagrams, policies) and their role in establishing guidelines and best practices.
