Network+ N10-009 Revision Sheet & Activities

A two-page revision handout for learners preparing for the CompTIA Network+ (N10-009) certification, written for post-16, BTEC/T Level IT and adult-education networking classes.

What is inside the PDF:

• Exam at a glance: up to 90 questions in 90 minutes, passing score 720 on a 100-900 scale
• The five N10-009 domains with their weightings (Networking Concepts 23%, Implementation 20%, Operations 19%, Security 14%, Troubleshooting 24%) and what to revise first in each
• OSI model table with protocol and device examples plus a memory hook
• The 20 port numbers learners are most often asked about (SSH 22, DNS 53, LDAPS 636, RDP 3389, SIP 5060/5061 and more)
• IPv4 subnetting quick table from /24 to /31 with usable host counts, private ranges and APIPA
• The seven-step CompTIA troubleshooting methodology in the order the exam expects
• Four 15-20 minute classroom activities: port bingo, a subnet relay, symptom fault cards and a five-question exit ticket

How to use it: hand it out at the start of the networking unit, then use the activities as starters. Learners who score below 4/5 on the exit ticket add that topic to their own revision list.
