Network+ Flashcards
Master networking terms, ports, and protocols. Flip through 10 real cards from our 350+ card Network+ deck.
10 Network+ terms to know
- SPAN
- Mirrors traffic from ports/VLANs to a monitoring port. Used for packet capture and IDS. Cisco term - others call it port mirroring.
- RADIUS
- AAA protocol using UDP ports 1812 (auth) and 1813 (accounting). Centralized authentication for network access. Used with 802.1X and VPNs.
- EAPoL
- Encapsulates EAP over wired networks for 802.1X port-based authentication. Authenticates before granting network access.
- BGP
- Path vector protocol routing between autonomous systems. Uses TCP port 179. The protocol that makes the internet work. eBGP between ASes, iBGP within.
- OSPF
- Link-state IGP using Dijkstra's algorithm. Uses areas for scalability. Protocol 89. Metric: cost (based on bandwidth). Fast convergence.
- VLAN
- Logical network segment within a switch. Separates broadcast domains. Trunk ports carry multiple VLANs using 802.1Q tags. Improves security and performance.
- APIPA
- Auto-assigns 169.254.x.x address when DHCP fails. Link-local only - can communicate with other APIPA hosts but not beyond the local network.
- STP
- Cabling with metallic shielding to reduce EMI. More expensive than UTP. Requires grounding. Used in high-interference environments.
- MDIX
- Auto-detects and adjusts for straight-through or crossover cables. Modern switches have Auto-MDIX, eliminating crossover cable needs.
- ESP
- IPsec protocol providing encryption AND authentication. Uses protocol 50. Preferred over AH because it encrypts the payload.
What's in the Network+ deck
Network+ requires solid memorization of port numbers, protocols, cable types, and networking concepts. Our flashcard decks make this easy with organized categories and spaced repetition. Perfect for memorizing the technical details that make or break your exam score.
Ports & Protocols
TCP/UDP ports, protocols, and their functions - heavily tested!
OSI Model
All 7 layers, their functions, protocols, and devices at each layer
Cables & Connectors
Ethernet, fiber, coax cables, and connector types with specs
Wireless Standards
802.11 standards, frequencies, speeds, and configurations
Network Commands
ipconfig, ping, tracert, netstat, nslookup, and more
Subnetting
Subnet masks, CIDR notation, and calculation shortcuts
Port Number Drills
Dedicated drills for memorizing common port numbers. You'll know 21, 22, 23, 25, 53, 80, 443, and dozens more by heart.
Visual Cards
Some concepts need visuals. Our cards include diagrams for cable types, connectors, and network topologies.
Acronym Master
Networking has endless acronyms. Learn what VLAN, NAT, PAT, DHCP, DNS, and hundreds more actually mean.
Quick Review Mode
Short on time? Quick review mode focuses on your weakest cards for maximum efficiency.
Frequently asked questions
- How many port numbers do I need to memorize?
- You should know at least 25-30 common ports cold (FTP, SSH, Telnet, SMTP, DNS, HTTP, HTTPS, etc). Our Port Memorization feature helps you drill these until they're automatic.
- Are the flashcards updated for N10-009?
- Yes! Our flashcards are aligned with the latest N10-009 exam objectives, including cloud networking and modern wireless standards.
- Should I study flashcards before or after practice questions?
- Start with flashcards to build foundational knowledge, then use practice questions to apply concepts. Return to flashcards for any terms you didn't recognize in questions.
- How do I remember all the cable types?
- Our cable flashcards include visual hints and real-world use cases. Associating cables with scenarios (Cat6 in offices, fiber between buildings) helps retention.
Practice Network+ PBQs
Performance-based questions (PBQs) are the hands-on simulations on the real exam. Practice them in our PBQ labs.
