Q: What is the difference between Type 1 and Type 2 hypervisors?
A: Type 1 (bare-metal): runs directly on hardware (ESXi, Hyper-V). Type 2 (hosted): runs on an OS (VirtualBox, VMware Workstation).
Q: What port does HTTPS use?
A: 443
Q: What is the CompTIA troubleshooting methodology?
A: 1. Identify problem, 2. Establish theory, 3. Test theory, 4. Plan of action, 5. Implement, 6. Verify, 7. Document.
Q: What is DDR5 RAM?
A: Latest generation of DDR SDRAM — higher bandwidth, lower voltage (1.1V), 288-pin (different key notch from DDR4).
Q: What is NVMe?
A: Non-Volatile Memory Express — high-speed storage protocol for SSDs using PCIe interface. Much faster than SATA.
Q: What is 802.11ax?
A: Wi-Fi 6 — supports 2.4 and 5 GHz, OFDMA, MU-MIMO, BSS coloring. Theoretical max ~9.6 Gbps.
Q: What does DHCP do?
A: Dynamic Host Configuration Protocol — automatically assigns IP addresses, subnet masks, default gateways, and DNS servers to devices.
Q: What is a PSU?
A: Power Supply Unit — converts AC mains power to DC voltages (3.3V, 5V, 12V) for computer components.
Q: What is an SFP module?
A: Small Form-factor Pluggable — hot-swappable transceiver for fiber/copper network connections on switches.
CompTIA Flashcard Study Technique
CompTIA exams cover broad domains with hundreds of concepts. Use these flashcards in short, focused sessions of 15–20 minutes rather than marathon study sessions. Group cards by domain and track which domains have the lowest recall rates — allocate extra study time to those areas. CompTIA exams weight domains differently, so match your flashcard focus to the domain percentages listed in the exam objectives.
