TCP/IP Protocols: Proficiency in TCP/IP protocols such as TCP, IP, UDP, ICMP, ARP, and DHCP.
Network Configuration: Ability to configure TCP/IP settings on devices, including IP addressing, subnet masks, and default gateways.
Network Troubleshooting: Skills in diagnosing and resolving TCP/IP-related network issues, including connectivity problems and performance issues.
Security: Awareness of TCP/IP security principles and best practices, including firewalls, encryption, and VPNs.
Who should take the exam?
Network Administrators: Individuals responsible for managing and maintaining computer networks.
Network Engineers: Professionals involved in designing and implementing network infrastructure.
System Administrators: IT personnel responsible for configuring and troubleshooting network services.
IT Support Technicians: Individuals providing technical support for network-related issues.
Cybersecurity Professionals: Those interested in understanding the TCP/IP protocol suite for security purposes.
