Built for Cisco CCNA 200-301 v1.1

Know Which CCNA Blueprint You're Studying

The exam code is 200-301, but Cisco can change the underlying blueprint version.

This guide is specifically written around:

Cisco CCNA 200-301 v1.1

According to the guide's version notice:

v1.1 remains available through February 2, 2027.

The guide identifies v2.0 as becoming the only option beginning February 3, 2027.

It also explains that the fundamentals—including subnetting, VLANs, STP, OSPF, and ACL concepts—carry across, while candidates testing after the transition need appropriate v2.0-specific preparation.

Planning to Take CCNA Before February 3, 2027?

This guide is designed around the v1.1 blueprint.

Testing February 3, 2027 or Later?

You'll need study material updated for the v2.0 blueprint.

Always verify the exam version and current blueprint directly with Cisco before scheduling your examination.

100 Cisco CCNA Practice Questions

Don't just read networking concepts.

Test whether you can apply them.

Your study guide contains 100 original practice questions divided according to the domain weighting:

• 20 Network Fundamentals questions

• 20 Network Access questions

• 25 IP Connectivity questions

• 10 IP Services questions

• 15 Security Fundamentals questions

• 10 Automation & Programmability questions

The practice exam is designed as a 120-minute session, and the guide specifically recommends practicing without going backward through questions to mimic an important constraint described in its CCNA exam overview.

Detailed Answer Explanations

Knowing the correct letter isn't enough.

A useful CCNA practice question should reinforce why the networking concept works the way it does.

The included explanations are designed to reinforce areas such as:

• Subnetting

• Routing decisions

• OSPF

• VLAN behavior

• STP

• Access lists

• Cisco commands

• Network security

• IP services

• Automation concepts

Use missed questions to identify weak domains rather than simply memorizing the answer key.

CCNA Subnetting Study Guide

Subnetting — One of the Most Important Skills to Practice

The guide gives subnetting dedicated attention and provides a quick-reference table for common prefix lengths:

/24 → 254 usable hosts

/25 → 126 usable hosts

/26 → 62 usable hosts

/27 → 30 usable hosts

/28 → 14 usable hosts

/29 → 6 usable hosts

/30 → 2 usable hosts

It then provides a repeatable four-step subnetting method rather than expecting you to guess your way through binary math.

A Four-Step Subnetting Method

The guide's approach is:

Step 1

Calculate block size:

256 − interesting mask octet

Step 2

Count subnet boundaries using that block size.

Step 3

Identify the boundary at or immediately below the host address.

That is your network address.

Step 4

The next boundary minus one gives you the broadcast address.

Usable addresses sit between the network and broadcast addresses.

The guide includes a worked example using 172.16.40.100/20 to demonstrate the process.

IPv4 & IPv6 Exam Review

Review important address ranges including:

RFC 1918 Private IPv4

• 10.0.0.0/8

• 172.16.0.0/12

• 192.168.0.0/16

APIPA

169.254.0.0/16

Often indicates that a client did not receive a DHCP response.

IPv6 Global Unicast

2000::/3

IPv6 Link-Local

FE80::/10

IPv6 Unique Local

FC00::/7

IPv6 Multicast

FF00::/8

You'll also review EUI-64, TCP vs. UDP, and related addressing concepts.

VLANs & 802.1Q Trunking

Understand core switching concepts including:

• VLAN 1

• Default VLAN

• Native VLAN

• 802.1Q

• Tagged frames

• Untagged native VLAN traffic

• Normal VLAN range

• Extended VLAN range

• CDP

• LLDP

• EtherChannel

• LACP

• PAgP

The guide also explains why EtherChannel member ports must agree on characteristics such as speed, duplex, trunk mode, and allowed VLANs.

Spanning Tree Protocol Exam Prep

Understand STP Instead of Merely Memorizing the Acronym

Review:

Root Bridge Election

Lowest bridge ID wins, based on priority and then MAC address.

Port States

• Blocking

• Listening

• Learning

• Forwarding

• Disabled

Port Roles

• Root port

• Designated port

• Non-designated / blocking

PortFast

Allows an appropriate access port to transition rapidly to forwarding.

BPDU Guard

Err-disables a port if it receives a BPDU.

Root Guard

Protects the intended root-bridge placement.

Loop Guard

Helps protect against certain unidirectional-link conditions that could create loops.

The guide notes that Root Guard, Loop Guard, BPDU Filter, and BPDU Guard were added by name to the v1.1 blueprint, making them important when comparing older study materials.

Routing Table & Administrative Distance

Learn How a Cisco Router Actually Chooses a Route

The guide presents the forwarding decision in this order:

1. Longest Prefix Match

The most specific route wins.

For example, a /24 can beat a /16 for a destination inside that /24 regardless of routing source.

2. Administrative Distance

Used when different sources advertise the same prefix.

3. Routing Metric

Used to choose among paths learned through the same protocol.

Administrative Distance Cheat Sheet

Review values including:

Directly Connected — 0

Static — 1

eBGP — 20

EIGRP Internal — 90

OSPF — 110

IS-IS — 115

RIP — 120

EIGRP External — 170

iBGP — 200

Unusable — 255

You'll also learn common routing-table codes and how administrative distance and metrics appear in a routing-table entry.

Single-Area OSPFv2 Exam Prep

OSPF is one of the most important routing concepts in the guide.

Review:

• Router ID selection

• DR/BDR election

• OSPF network types

• Neighbor states

• OSPF cost

• Multicast addresses

• Hello/dead timers

• Adjacency problems

• Area 0

Know the neighbor-state sequence:

Down → Init → 2-Way → Exstart → Exchange → Loading → Full

You'll also review common adjacency blockers such as mismatched:

• Area IDs

• Timers

• Subnet masks

• MTU

• Authentication

The guide specifically notes that two non-DR routers remaining in 2-Way on a broadcast segment can be normal rather than an adjacency failure.

HSRP & First-Hop Redundancy

Review Hot Standby Router Protocol concepts such as:

• Virtual IP

• Virtual MAC

• Active router

• Standby router

• Priority

• Tie-breaking

• Preemption

HSRP allows hosts to use a shared virtual gateway so connectivity can survive a router failure.

You'll also review inter-VLAN routing using:

Router-on-a-Stick

or

SVIs on a Layer 3 Switch.

IP Services Exam Prep

Review common network services and operational concepts:

NAT

• Static NAT

• Dynamic NAT

• PAT / NAT Overload

• Inside Local

• Inside Global

NTP

Uses UDP port 123.

DHCP Relay

Use ip helper-address because routers don't normally forward DHCP broadcasts.

SNMP

Review managers, agents, traps, and SNMPv3.

Syslog

Know severity levels from:

0 Emergency → 7 Debugging

Lower numbers represent greater severity.

QoS

Understand the difference between:

Policing — drops/re-marks excess traffic.

Shaping — buffers/delays excess traffic.

Cisco ACL Exam Prep

Access Control Lists deserve focused practice.

Standard ACLs

Match the source address only.

The guide recommends placement closer to the destination.

Extended ACLs

Can match:

• Source

• Destination

• Protocol

• Port

The guide recommends placement closer to the source.

Implicit Deny

Every ACL ends with an invisible:

deny any

Evaluation Order

ACLs are evaluated:

Top to bottom → First match wins.

Wildcard Masks Made Easier

Invert the Subnet Mask

The guide provides examples:

/24

Subnet mask: 255.255.255.0
Wildcard: 0.0.0.255

/26

Subnet mask: 255.255.255.192
Wildcard: 0.0.0.63

/27

Subnet mask: 255.255.255.224
Wildcard: 0.0.0.31

/30

Subnet mask: 255.255.255.252
Wildcard: 0.0.0.3

Single Host

Wildcard: 0.0.0.0

The guide emphasizes practicing wildcard conversion because wildcard masks appear in both ACL and OSPF-related contexts.

Layer 2 Security

Review practical switch-security scenarios.

Rogue DHCP Server

→ DHCP Snooping

ARP Poisoning

→ Dynamic ARP Inspection

MAC Flooding / CAM Overflow

→ Port Security

Unauthorized Switch Connected to Access Port

→ BPDU Guard

You'll also review port-security violation modes:

Shutdown

Restrict

Protect

and how each handles a violation.

AAA, TACACS+ & RADIUS

Understand the three A's:

Authentication

Who are you?

Authorization

What are you allowed to do?

Accounting

What did you do?

The guide also compares:

TACACS+

Uses TCP 49 and is particularly suited to device administration.

RADIUS

Uses UDP 1812/1813.

The guide emphasizes the distinction between how the protocols handle AAA and encryption.

Automation & Programmability

Modern networking isn't only CLI commands.

The CCNA v1.1 material also includes automation and programmability.

Review:

Software-Defined Networking

Separates the control plane from the data plane.

Northbound APIs

Controller → Applications

Southbound APIs

Controller → Network Devices

Examples include:

• NETCONF

• RESTCONF

• OpenFlow

REST APIs

Review CRUD operations:

POST → Create

GET → Read

PUT/PATCH → Update

DELETE → Remove

You'll also review HTTP status-code categories, JSON, Ansible, Terraform, controller-based networking, and AI/ML concepts in network operations.

Cisco IOS Command Review

CCNA candidates need to recognize and use Cisco IOS commands.

The guide incorporates configuration and verification concepts involving commands such as:

show vlan brief

show interfaces trunk

show spanning-tree

show cdp neighbors

show ip route

show ip interface brief

show ip ospf neighbor

and other verification commands.

That helps bridge the gap between conceptual questions and actual Cisco device administration.

CCNA Requires Hands-On Lab Practice

This PDF Is a Study Guide — Not a Replacement for the CLI

This is an important distinction, and the guide is refreshingly explicit about it.

The CCNA examination isn't purely multiple choice.

Candidates may encounter simulations and simlets requiring them to configure or troubleshoot Cisco environments.

No PDF can replace actually using Cisco IOS.

The guide therefore recommends pairing the PDF with hands-on practice using resources such as Cisco Packet Tracer or CML, including exercises involving:

• Building VLANs

• Configuring trunks

• Configuring OSPF

• Writing ACLs

• Breaking configurations deliberately

• Troubleshooting the problems you created

It recommends devoting substantial study time to CLI practice.

That makes this guide an exam-prep companion, not a substitute for practical networking experience.

Eight-Week CCNA Study Plan

Don't know where to begin?

The guide includes an eight-week preparation framework.

Week 1 — Network Fundamentals

Devices, cabling, TCP/UDP, IPv4 and daily subnetting.

Week 2 — IPv6 & Networking Concepts

IPv6, wireless, virtualization, switching fundamentals and initial Packet Tracer work.

Week 3 — Network Access

VLANs, trunks, native VLANs, CDP, LLDP and EtherChannel.

Week 4 — Spanning Tree

Root election, states, roles, PortFast, BPDU Guard, Root Guard and Loop Guard.

Week 5 — IP Connectivity

Routing tables, administrative distance, static routes and floating static routes.

Week 6 — OSPF & HSRP

Build and troubleshoot a multi-router OSPF Area 0 topology.

Week 7 — Services, Security & Automation

IP services, ACLs, wildcard masks, security, and automation concepts.

Week 8 — Practice & Simulation

Complete the 100-question practice exam under timed conditions and concentrate heavily on simulation practice.

The study plan sets concrete checkpoints rather than merely assigning chapters to read.

Network+ vs. CCNA

If you've already studied CompTIA Network+, many networking fundamentals will look familiar.

But CCNA adds an important dimension:

Cisco Configuration & Troubleshooting

Network+ may help you understand concepts such as:

• Routing

• Switching

• IP addressing

• VLANs

• Wireless

• Network security

CCNA expects you to go further into areas such as:

• Cisco IOS

• Cisco commands

• OSPF configuration

• Switch configuration

• VLAN configuration

• ACL configuration

• Network troubleshooting

The guide itself notes that Network+ holders may recognize much of the early conceptual material while finding the Cisco CLI comparatively new.

Learn Networking — Then Practice Configuring It

The CCNA is not an exam you should approach by simply memorizing a few hundred definitions.

You need to understand things like:

Which route wins?

Which switch becomes the STP root?

Why won't these OSPF neighbors form?

Which wildcard mask belongs in this ACL?

Which VLAN should this frame enter?

What command verifies the configuration?

And then you need enough hands-on practice to actually work with those concepts in Cisco IOS.

That's the value proposition of this study guide:

Learn the concept → Review the command → Practice the question → Build it in the lab.
