What should CCNA flashcards cover?
CCNA flashcards should cover OSI model layers with protocols at each layer, IPv4 subnetting formulas and magic number method, IOS show commands and their outputs, routing protocol characteristics (OSPF, EIGRP, BGP basics), VLAN and trunking concepts, STP port states and roles, NAT/PAT configurations, and common port numbers. Port numbers, protocol names, and IOS command syntax are the highest-priority flashcard content because they must be recalled instantly during exam simulation questions.
The Cisco CCNA 200-301 exam is one of the most demanding associate-level certifications for flashcard preparation because it combines conceptual knowledge (networking theory, protocol behavior) with precise technical recall (IOS command syntax, port numbers, subnetting formulas). Both knowledge types need to be instantaneously available during an exam with simulation questions where you must type commands precisely.
CCNA Flashcard Categories and Priority
Very High Priority: Instant Recall Required
OSI Model (7 cards + associations) Create one card per layer covering the layer name, number, PDU type, and key protocols:
- Layer 7 Application: HTTP, HTTPS, DNS, DHCP, FTP, SSH, SMTP
- Layer 6 Presentation: SSL/TLS, encoding, encryption
- Layer 5 Session: NetBIOS, RPC, session establishment
- Layer 4 Transport: TCP (connection-oriented), UDP (connectionless), segments/datagrams
- Layer 3 Network: IP, ICMP, routing; PDU = packet
- Layer 2 Data Link: Ethernet, 802.11, 802.1Q, MAC addressing; PDU = frame
- Layer 1 Physical: Cables, signals, bits; PDU = bit
IOS Show Commands (15-20 cards) Each card: Command → What it shows / when to use it
Examples:
show ip route→ Full routing table including source, network, metric, next-hopshow ip interface brief→ All interfaces with IP and status summaryshow running-config→ Current active configuration in memoryshow vlan brief→ VLAN IDs, names, and port assignmentsshow spanning-tree→ STP root, port states, port roles
Common Networking Port Numbers (20-25 cards) Each card: Port → Protocol name + function Cover: 20, 21, 22, 23, 25, 53, 67, 68, 80, 110, 119, 143, 161, 389, 443, 445, 993, 995
High Priority: Concept Distinctions
Routing Protocol Comparison (10-15 cards)
| Topic | Card Example |
|---|---|
| OSPF metric | Cost = reference bandwidth / interface bandwidth |
| EIGRP metric | Composite (bandwidth + delay; optionally load, reliability) |
| OSPF area 0 | Backbone area; all other areas must connect to it |
| OSPF neighbor states | Down > Init > 2-Way > ExStart > Exchange > Loading > Full |
| Routing protocol types | Distance vector vs link-state vs hybrid |
VLAN and Trunking (15-20 cards)
- Access port: assigned to single VLAN, carries untagged frames
- Trunk port: carries multiple VLANs using 802.1Q tagging
- Native VLAN: untagged VLAN on trunk (default VLAN 1)
- VTP (VLAN Trunking Protocol): propagates VLAN configs across switches
STP Port States (5 cards)
- Blocking → Listening → Learning → Forwarding (and Disabled)
- Blocking: receives BPDUs but does not forward data
- Learning: builds MAC table but does not forward data
- Forwarding: normal operation
Medium Priority: Supporting Concepts
Subnetting Reference (8-10 cards) Create cards for the magic number method steps and key prefix facts:
- /24 = 254 hosts, /25 = 126, /26 = 62, /27 = 30, /28 = 14, /29 = 6, /30 = 2
- Magic number formula: 256 minus the subnet mask value in the interesting octet
IPv6 Address Types (8-10 cards)
- ::1/128 = loopback
- fe80::/10 = link-local
- fc00::/7 = unique local
- 2000::/3 = global unicast
- ff00::/8 = multicast
Recommended Anki Settings for CCNA
CCNA has a large card count. Manage the daily load to prevent review backlog:
New cards per day: 20-25 (increases through preparation, peaks at 30 in weeks 5-8) Review time daily: 20-30 minutes Card types: Use basic front/back for definitions; use cloze deletion for IOS commands (fill-in-the-blank format)
Cloze deletion example for IOS commands: "To view the IPv4 routing table on a Cisco router, use {{c1::show ip route}}"
Cloze format forces active recall of the command syntax rather than recognition.
Community CCNA Anki Decks
AnkiWeb resources: Search "CCNA 200-301" on ankiweb.net/shared/decks/. Top-downloaded decks typically have 400-700 cards.
Reddit r/ccna: Community members post links to well-reviewed Anki decks. Search "Anki deck" filtered to past 12 months for current exam version decks.
Odom OCG companion decks: Some study groups create Anki decks aligned chapter-by-chapter to Wendell Odom's Official Cert Guide. These provide good alignment to the most-used study book.
"I made every IOS show command a separate Anki card. On the simulation question asking me to verify the routing table, I typed show ip route before the question finished loading because the muscle memory was there. Cards for commands are worth every minute of creation time." -- CCNA candidate
Frequently Asked Questions
Are subnetting flashcards helpful for CCNA? Subnetting flashcards help with memorizing prefix-to-host relationships and subnet mask conversions. However, subnetting speed requires practiced calculation, not just recall. Anki cards reinforce the mathematical relationships; actual subnetting practice drills (SubnettingPractice.com) build the calculation speed that exam conditions require.
How many CCNA flashcards are enough? A comprehensive CCNA Anki deck typically contains 400-600 cards. The exam is broad, and all major topic areas require some flashcard coverage. However, IOS commands, port numbers, and routing protocol distinctions benefit most from flashcard memorization and should receive the most cards.
Should I create CCNA flashcards as I study or after finishing the book? Create cards as you study, chapter by chapter. Creating cards after finishing the book requires re-reading to identify card content, doubling the time investment. Concurrent creation adds 10-15 minutes per chapter and produces better retention of the chapter content.
