Huawei H20-923_V1.0 Exam - Topic 7 Question 5 Discussion
Topic #: 7
In a data center fire protection design, which approach best matches Huawei facility practice for protecting IT rooms while minimizing secondary damage to IT equipment?
Huawei data center facility design typically follows a layered fire protection concept: early detection, controlled alarm linkage, and suppression methods that protect equipment and ensure personnel safety. A smoke detection system (often combined with staged alarms) provides early warning so operators can verify events and initiate emergency procedures. For the IT white space, a clean-agent gas extinguishing system is preferred because it suppresses fire without leaving residue and significantly reduces the risk of corrosion or contamination compared with powder-based agents. The extinguishing system is normally integrated with linkage/interlock controls: audible/visual pre-discharge alarms, time delay, emergency abort, door access control logic, and HVAC shutdown or damper control to help maintain agent concentration. This coordinated mechanism reduces false discharge risk while preserving a reliable automatic response if a real fire develops. In contrast, relying only on manual extinguishers is too slow for rapid fire growth, and water sprinklers alone can cause substantial collateral damage to servers and power equipment.
