SY0-701 Study Guide + Practice
Short notes + common traps + quick practice. Then validate with the mini test.
Quick answers
- Read notes → do 10 questions → review mistakes immediately.
- Write 1 rule per mistake (symptom → cause → fix / concept → example).
- Repeat within 24–48 hours to lock it in.
- When accuracy is stable, switch to timed simulator practice.
These Security+ SY0-701 notes cover the ports and protocols you’re expected to recognize instantly in scenarios (network troubleshooting, incident response, and secure configuration).
Fast approach: learn the “identity set” (LDAP/Kerberos/RADIUS/TACACS+), the “remote admin set” (SSH/RDP), and the “core services set” (DNS/DHCP/NTP/HTTP(S)).
Do the mini quiz to check recall. Then continue in PrepMaster for offline packs, timed practice, and detailed explanations.

Frequently Asked Questions
Do I need to memorize every port for SY0-701?
No — focus on the most common ones that appear in scenarios (DNS/DHCP/HTTP(S)/SSH/RDP/SMB/LDAP/Kerberos/NTP/SNMP/Syslog).
What’s the fastest way to learn ports?
Group them by purpose (web, identity, remote admin, monitoring, email). Drill short daily sets and repeat mistakes within 24–48 hours.
Why do some protocols use both TCP and UDP?
UDP is used for fast queries/telemetry, while TCP is used when reliability or larger transfers matter (for example some DNS operations).
