CompTIA Network+ Protocols Flashcards
CompTIA Network+ N10-009 (V9) Flashcards
| Front | Back |
| APIPA | Automatic Private IP Addressing. Assigned to Windows OS's if DHCP fails. 169.254.0.0-169.254.255.255 |
| ARP | Address Resolution Protocol; Discovers network devices on a LAN; Records MAC Addresses of LAN. |
| BGP | Border Gateway Protocol; Exterior Gateway routing protocol used for exchanging routing information between network systems. Typically found at the ISP level. |
| DHCP | Dynamic Host Configuration Protocol; Dynamically assigns IP, DNS, and subnet mask to network devices. Ports 67, 68. |
| DNS | Domain Name Server/Service; Port 53 |
| EIGRP | Enhanced Interior Gateway Routing Protocol; Cisco distance-vector routing protocol. |
| FTP | File Transfer Protocol; Ports 20 and 21 |
| HTTP | Hypertext Transfer Protocol; Port 80 |
| HTTPS | Hypertext Transfer Protocol + SSL/TLS; Port 443 |
| ICMP | Internet Control Message Protocol |
| IP | Internet Protocol; Layer 3 |
| IPv4 | Internet Protocol version 4; 32 Bits; Dotted Decimal format |
| NAT | Network Address Translation; Translates between IP addresses of different networks. Typically between private and public IP networks. |
| NTP | Network Time Protocol; port 123 |
| OSPF | Open Shorteset Path First; Link-state routing protocol. |
| PAT | Port Address Translation (Aka NAT Overload). Type of NAT that uses 1 to many IP translations by utilizing layer 4 port numbers. |
| POP3 | Post Office Protocol; Port 110 |
| RIP | Routing Information Protocol. Basic, distance vector routing protocol. |
| SMTP | Simple Mail Transfer Protocol; Port 25 |
| SNMP | Simple Network Management Protocol; Port 161 |
| SSH | Secure Shell; Port 22 |
| TCP | Transmission Control Protocol |
| Telnet | Unencrypted; Port 23 |
| TFTP | Trivial File Transfer Protocol; Port 69 |
| UDP | Uniform Datagram Protocol; Layer 4 |

About the Flashcards
Flashcards for the CompTIA Network+ exam give targeted review of core networking terminology and functions. The deck covers key Internet and transport protocols (IP, IPv4, ICMP, TCP, UDP), address resolution and assignment (ARP, DHCP, APIPA), common service ports, and utilities such as DNS, NTP, and SNMP to help students master definitions and roles tested on the exam.
Use these cards to reinforce address assignment and translation concepts (DHCP, APIPA, NAT/PAT), routing fundamentals and protocol types (RIP, OSPF, EIGRP, BGP), and application-layer services including HTTP/HTTPS, FTP/TFTP, SMTP/POP3, and remote access tools. Emphasis is on concise definitions, port numbers, and practical distinctions you'll need to recall under exam conditions.
Topics covered in this flashcard deck:
- IP addressing and IPv4
- TCP and UDP
- Common service ports
- DHCP and APIPA
- NAT and PAT
- Routing protocols (RIP, OSPF, EIGRP, BGP)
