Jeopardy Review - CST8208 Part 3

• The review covers troubleshooting procedures, CPU and socket components, expansion buses, and server rack specifications
• The first troubleshooting step is to identify the problem
• If changes to a client's system are suspected, back up the system first
• The third step is testing the suspected theory by swapping hardware or trying generic drivers
• After implementing a solution, verify the functionality
• Consistently document findings throughout the troubleshooting process
•  A gold triangle on the CPU socket indicates pin 1
• LGA (Land Grid Array) sockets have pins in the socket versus on the processor
• Thermal compound is applied between the CPU and its heatsink
• AMD (Advanced Micro Devices) is Intel's main competitor in the CPU market
• Hyper-threading is a feature that tricks the operating system into believing that a processor has double the cores it actually has
• PCI Express is a serial expansion bus that's commonly used in today's PCs
• PCI is a parallel 32-bit bus that's being phased out
• PCI-X is the only expansion slot that allows backward compatibility with traditional PCI cards
• x1 is the shortest PCIe slot often found on modern motherboards
• Plug and Play is a feature of many modern expansion buses and allows self-configuration
•  Server racks are 19 inches wide
• A 5U server chassis is 8.75 inches tall
• The main power connector on a server motherboard has 24 pins (same as ATX)
• Xeon is a common server-class Intel processor line
• A headless server lacks a connected monitor
