CompTIA Server SK0-004 Server Architecture. match the types of north american plugs to their descriptions – ✔ Twist Lock plug - has three curved plates Edison plug - has two flat plates and one round plate and can be disassembled. Standard NEMA plug - has two flat plates and one round plate and cannot be disassembled. which statements are true about BIOS and UEFI configurable interfaces? - ✔ The interface can be used to configure the processor, RAM, and storage. UEFI has better capabilities for newer hardware. You can set a password on the interface. The CMOS battery provides power to enable interface settings to be stored. Every system has either a BIOS or a UEFI interface. What do you need to take into consideration when installing, configuring, and maintaining cpu's? - ✔ The L1 cache is built into the processor. the X86-based processor can address up to four gigabytes of RAM. a multi-core processor uses shared memory more effectively than a multiprocessor. 64-bit processors are the recommended type for servers. as a processor processes the information, it can store the information it has processed in the cache while it fetches the next set of instructions. mention some features of blade technology. - ✔ a blade server uses less space than a rack mounted and tower servers. the blade enclosure's back-plane provides a central connection point for each blade. a blade server shares power supply, network modules, and management modules. a blade server may use less power than a rack mounted server. match the server components to their characteristics. - ✔ RAID controllers- -allow you to write and read from all disks simultaneously -increase server performance -provide storage redundancy Riser cards- -provide more expansion slots for adding devices -provide a way to save space What do you need to take into consideration when installing, configuring, and maintaining firmware? - ✔ Upgrading firmware may resolve problems while installing new hardware. Ideally, a firmware update should be tested before it's rolled out more widely. Firmware provides the ability to configure hardware directly. Computers, routers, and switches are considered firmware devices. Which statements describes how 3-phase power works? - ✔ Three waves are timed in thirds of a unit of measurement. What do you need to take into consideration when installing, configuring, and maintaining USB interfaces and ports? - ✔ Type Backward compatibility Typical device usage Speed What can you do with a hot-swappable device that you cannot do with a non-hot- swappable device without turning it off? - ✔ Remove it Attach it what do you need to take into consideration when installing, configuring, and maintaining RAM? - ✔ Memory pairing allows the processor to access memory in dual channels A RAM chip must have the correct number of pins to fit in the motherboard. DDR3 RAM doubles the number of bit transferred when compared to DDR2. ECC RAM uses its monitoring chip to prevent errors. Match each server form factor to its advantages. Each form factor is used more than once. - ✔ Rack-mounted server- -includes cable management arms -takes up less space -can use rail kits Tower servers- -Takes less power to cool -Has more room to work in Which statements are true about cooling components? - ✔ Heat sync spreads the heat from a component over a larger area. Baffles and shrouds ensure that a fan blows directly onto a specific component. Liquid cooling produces less noise that fans. Newer components may use liquid cooling. A component may have its own fan to blow air over it. Which statements are true about expansion slots? - ✔ Expansion slots are used to extend server capabilities. The type of bus is the devices's bit rate. The height of the device affects whether it will fit in the server form factor or not. What do you need to take into consideration regarding power components? - ✔ Wattage is an overall amount of work that can be drawn from the power supply. Some systems may have two power supplies. An uninterruptible power supply can be used to provide redundancy.
