問題 #55
The three elements of the fire triangle are,and. (Choose three.)
- A. Earth
- B. Water
- C. Fuel
- D. Heat
- E. Oxygen
答案:C,D,E
解題說明:
The fire triangle is a simple model that illustrates the three elements that a fire needs to ignite and sustain:
oxygen, heat, and fuel. Oxygen is the oxidizing agent that enables the combustion reaction, heat is the energy source that raises the temperature of the fuel to its ignition point, and fuel is the material that reacts with oxygen and releases heat and light. Removing any one of these elements can extinguish a fire. For example, water can reduce the heat and the oxygen, sand or soil can smother the fuel and the oxygen, and fire extinguishers can displace the oxygen or lower the temperature.

問題 #56
Starting from which Rating does the requirement of Concurrently Maintainability becomes relevant?
- A. Rated-3
- B. Rated-4
- C. Rated-1
- D. Rated-2
答案:A
解題說明:
The requirement of Concurrently Maintainability becomes relevant starting from Rated-3, according to the Uptime Institute Tier Classification System1. Concurrently Maintainability means that any component or system in the data centre can be maintained or replaced without affecting the availability of the IT equipment.
This requires having redundant capacity components and multiple independent distribution paths serving the IT equipment. Rated-3 data centres are designed to achieve Concurrently Maintainability and have a minimum uptime of 99.982%. Rated-4 data centres also have Concurrently Maintainability, but they also have Fault Tolerance, which means that they can withstand any single unplanned event without affecting the availability of the IT equipment. Rated-4 data centres have a minimum uptime of 99.995%. Rated-1 and Rated-2 data centres do not have Concurrently Maintainability, as they have only one distribution path serving the IT equipment and no redundant capacity components. Rated-1 data centres have a minimum uptime of
99.671% and Rated-2 data centres have a minimum uptime of 99.741%.

問題 #58
What is a requirement of an FM200 (HFC-227) installation?
- A. Install pre-action sprinklers in the same room as the FM200.
- B. It is a high-pressure gas; therefore nozzles must be mounted with two brackets.
- C. Install the gas containers (tanks) close to the data centre.
- D. Drainage system under the raised floor.
答案:B
解題說明:
FM200 (HFC-227) is a clean agent fire suppression system that uses a high-pressure gas to extinguish fires by reducing the oxygen concentration and absorbing the heat. FM200 is stored in cylinders at pressures of up to
42 bar (600 psi) and is released through nozzles into the protected area. Because of the high pressure, the nozzles must be mounted with two brackets to prevent them from moving or breaking during discharge. The brackets must be securely attached to the ceiling or wall and aligned with the nozzle outlet. The nozzle outlet must also be free of any obstructions that could affect the discharge pattern or distribution.
