Cheat Sheet
- Windows OS Installation & File Systems -
When tackling the CompTIA A+ practice exam, understanding partition schemes (MBR vs GPT) and file systems (NTFS vs FAT32) is essential for Windows OS exam prep. Learn Disk Management GUI and Diskpart commands, plus run chkdsk /f and sfc /scannow to maintain file integrity.
- Networking Fundamentals & the OSI Model -
For your CompTIA A+ 220-901 quiz, master the seven OSI layers using the mnemonic "All People Seem To Need Data Processing." Know common TCP/UDP ports (e.g., 80, 443, 53) and cable types (Cat5e vs Cat6) to ace IT certification practice test networking questions.
- Hardware Components & Diagnostic Tools -
Review motherboard form factors, CPU socket types, and RAM generations (DDR3 vs DDR4) from reputable hardware guides. Practice using a multimeter to check PSU voltages (12V/5V rails) and interpret POST beep codes with a loopback plug for quick troubleshooting.
- Virtualization, Cloud & Mobile Device Features -
Differentiate Type 1 hypervisors (VMware ESXi) from Type 2 (VirtualBox) and grasp cloud models (IaaS, PaaS, SaaS) as outlined by official vendor docs. Understand mobile OS quirks (iOS sandboxing vs Android fragmentation) to handle CompTIA troubleshooting questions on portable devices.
- Security Fundamentals & Best Practices -
Memorize encryption standards (AES for symmetric, RSA for asymmetric) and implement the principle of least privilege in line with NIST guidelines. Recognize social engineering tactics (phishing, vishing) and configure firewalls, VPNs, and WPA2/PW3 for a robust security posture.
