Practical TCP/IP Training Course

Objectives:

• Explain encapsulation, de-encapsulation, and modularity within the TCP/IP protocol stack for government network operations.
• Identify and describe the fields and flags within the IP header to support network management and security for government systems.
• Describe and identify IP address classes A, B, and C for effective network design in public sector environments.
• Use subnet masks to determine the network portion of an IP address, ensuring accurate network segmentation for government networks.
• Distinguish between classful and classless IP addressing methods to optimize resource allocation for government IT infrastructure.
• Explain the operation of IP routers and the application of static and dynamic routing techniques in government network configurations.
• Compare distance vector (RIP) and link-state (OSPF) routing protocols to inform decision-making in government network design.
• Describe and explain IP subnetworking for efficient management of government network resources.
• Explain supernetting, Variable Length Subnet Masking (VLSM), and Classless Inter-Domain Routing (CIDR) for government network scalability.
• Describe the use of ICMP and demonstrate how to use ping and traceroute as tools for assessing network connectivity in government IT environments.
• Explain the role of DHCP in dynamic IP addressing for government networks, ensuring flexible and secure network management.
• Use ARP to map IP addresses to MAC addresses, facilitating accurate device identification in government IT systems.
• Describe the function of DNS in TCP/IP networks, supporting reliable domain name resolution for government operations.
• Identify and explain the fields and flags in the TCP and UDP headers to enhance understanding of protocol behavior for government network diagnostics.
• Explain how TCP ensures end-to-end reliability in an unreliable IP network, ensuring robust data transmission for government communications.
• Describe and explain congestion avoidance mechanisms in TCP/IP networks to maintain optimal performance for government IT systems.
• Explain the principles and use of Transport Layer Security (TLS) to secure government data transmissions over the internet.
