Network Protocols — CompTIA Network+ (N10-009) Practice Questions
Network protocols are the standardized rules that govern how devices communicate, and the N10-009 exam requires candidates to know the purpose, port numbers, and behavior of dozens of protocols across all OSI layers. Commonly tested protocols include TCP, UDP, IP, ICMP, ARP, DNS, DHCP, HTTP, HTTPS, FTP, SSH, SNMP, NTP, and various routing protocols such as OSPF, BGP, and EIGRP. Candidates must also understand when one protocol is preferred over another, for example choosing SFTP or FTPS over plain FTP for secure file transfer. Protocol knowledge underpins nearly every troubleshooting and design question on the exam.
