A 6-Week Study Plan for the Cisco CCNA 200-301

The Cisco CCNA 200-301 is the entry-level networking cert that hiring teams actually still recognize. About 100 questions, 120 minutes, $300, multiple-choice plus drag-drop and simulation items. It is also the cert most candidates underestimate because the exam guide reads like a vocabulary list and the real exam tests configuration judgment under time pressure.

This is a six-week plan tuned for someone who has touched a router before but is not living in the CLI. About ten hours per week.

Week 1: Network fundamentals (20%)#

Anchor week.

• OSI and TCP/IP layers, encapsulation, end-to-end packet flow.
• Cabling and physical media: copper, fiber, transceiver types.
• IPv4 addressing, subnetting, supernetting. Practice subnetting until you can do a /27 from a /24 in your head.
• IPv6 addressing, link-local, EUI-64, address types.
• Common protocols and ports.

Hands-on: install Cisco Packet Tracer or set up a CML lab. Build a two-router, four-host topology and verify connectivity. Watch a packet traverse with show ip route and traceroute.

Week 2: Network access (20%)#

Switching week.

• VLANs and trunking (802.1Q), native VLAN, voice VLAN.
• Spanning Tree Protocol: states, root bridge election, PortFast, BPDU Guard, Rapid PVST+.
• EtherChannel: LACP, PAgP, static.
• Wireless concepts: CAPWAP, WLC, AP modes, SSIDs, security types (WPA2, WPA3).
• Wireless QoS basics.

Hands-on: configure trunk ports, an EtherChannel, and a simple wireless infrastructure in your lab. Break STP intentionally (loop two switches), watch the convergence, then add BPDU Guard.

Week 3: IP connectivity (25%)#

The largest single domain. Spend a full week.

• Routing concepts: routing decision, longest match, administrative distance, metric.
• Static routing: standard, default, floating static.
• OSPFv2 single-area: neighbor states, DR/BDR election, cost calculation, network types.
• First-hop redundancy: HSRP, plus a working knowledge of VRRP and GLBP.
• Routing table interpretation under failures.

Hands-on: build a three-router OSPF area and verify with show ip ospf neighbor and show ip route ospf. Then add static and floating static routes and test failover.

Week 4: IP services (10%) plus security fundamentals (15%)#

Two domains, one week.

• DHCP and DHCP relay (ip helper-address).
• DNS, NTP, SNMP, syslog, FTP, TFTP. SCP and SSH for secure remote management.
• NAT/PAT inside vs outside, static vs dynamic.
• QoS basics: classification, marking, queuing, policing vs shaping.
• Security: defense-in-depth concepts, AAA, RADIUS vs TACACS+, password types, port security.
• Access lists: standard vs extended, named vs numbered, placement.

Hands-on: configure SSH, port security, a standard ACL on a vty line, and an extended ACL filtering a specific application. Configure NAT overload on the edge router.

Week 5: Automation and programmability (10%)#

Often skipped, often costs candidates the pass.

• Network programmability concepts: traditional vs controller-based.
• SDN architecture: data plane, control plane, management plane.
• REST APIs: methods, status codes, JSON vs XML payloads.
• Configuration management: Ansible, Puppet, Chef at concept level.
• JSON parsing of API responses.
• Cisco DNA Center fundamentals.

Hands-on: hit a public REST API (any one, not necessarily Cisco) with curl. Parse the JSON response. Read a small Ansible playbook and trace what it does.

Week 6: Practice exams and weak-spot drilling#

No new material. All review.

• Two timed full-length practice exams under exam conditions (120 minutes, no notes).
• Score by domain. Anything under 70% gets a half-day focused review.
• Re-read your week 1 subnetting notes. Subnet five problems before bed each night.
• Final lab: configure a small office topology end-to-end (VLANs, trunk, OSPF, default route, NAT, ACL) from a topology diagram alone.

Day before exam: light review. Subnetting drills. Sleep.

Total time budget#

About sixty hours:

• 12 hours network fundamentals.
• 12 hours network access (switching).
• 14 hours IP connectivity (routing).
• 8 hours IP services and security.
• 6 hours automation.
• 8 hours practice exams.

If you have never touched a router CLI, add a week. Hands-on hours move your score more than reading hours, especially on the simulation items.

What to drop if you fall behind#

If you lose a week, compress automation (week 5) into two days and skim. Do not compress week 3 (IP connectivity, 25% of the exam) or the hands-on labs in weeks 2 and 3.

The one trap that fails candidates#

Subnetting under time pressure. Candidates who can subnet on a whiteboard with infinite time often blank when the exam clock is ticking. Drill subnetting daily for at least the last two weeks. If you can answer "give me the first usable host in 192.168.16.32/27" in under fifteen seconds, you are in the right zone.
