THE CCNA PRACTICE ARCADE
Learn by doing.
Small missions. Helpful hints. Zero judgment. Try a challenge, learn from the feedback, and come back stronger.
Every attempt is practice. Finish a mission to earn your first badge.
MISSION 01 · QUICK MATH, CLEAR STEPS
Subnet Sprint ⚡
Pick the correct network address for the given host and prefix. No timer—think it through.
What is the network address?
Use the block-size method: 256 − mask octet, then find the block.
MISSION 02 · FOLLOW THE EVIDENCE
Troubleshooting Quest 🕵️
Read the symptoms, choose your next best check, and follow the evidence like a network specialist.
A user cannot reach a server in another subnet.
The link light is on. The PC can ping its default gateway, but the remote server times out.
What is the best next check?
Choose the next test that narrows the problem without changing the network.
MISSION 03 · CONFIGURE WITH CONFIDENCE
VLAN Config Studio 🧰
Build a safe access-port configuration. Change the values and watch the Cisco IOS commands update.

KEEP THE MOMENTUM
Small reps build strong instincts.
Repeat a mission until the reasoning feels natural. Mistakes are clues, not grades.
