CISSP® Certification Domain 3: Security Architecture and Engineering Video Boot Camp for 2022 - Fire suppression and hot

The video tutorial discusses the importance of maintaining optimal temperature and humidity levels in data centers to ensure equipment longevity and efficiency. It highlights the need for positive pressure to keep contaminants out and the significance of regular subfloor cleaning to prevent fire suppression system activation. The tutorial also covers static electricity prevention and the use of fire suppression systems, emphasizing the importance of proper airflow management and the potential risks of water in subflooring.

What is the recommended temperature range for optimal equipment performance in data centers?

• 50 to 60 degrees Fahrenheit

• 68 to 77 degrees Fahrenheit

• 80 to 90 degrees Fahrenheit

• 95 to 105 degrees Fahrenheit

Why is it important to maintain positive air pressure inside a data center?

• To reduce electricity costs

• To keep contaminants out

• To increase humidity levels

• To improve employee comfort

What can happen if the subfloors in a data center are not cleaned regularly?

• The equipment will overheat

• The fire suppression system may be triggered

• The air pressure will drop

• The data center will become too humid

How are hot and cold aisles used in data centers?

• To manage airflow and cooling

• To store backup power supplies

• To separate different types of equipment

• To organize cables and wires

What is the purpose of having perforated grates in the floor of a data center?

• To support heavy equipment

• To improve lighting

• To allow for easy cleaning

• To facilitate airflow

What type of sensor uses a small radioactive source to detect smoke?

• Photoelectric sensor

• Ionization detector

• Infrared sensor

• Flame detector

What is a common procedure when a fire alarm is triggered in a data center?

• Check for an actual fire and delay suppression if necessary

• Wait for the fire suppression system to activate

• Turn off all equipment

• Immediately evacuate the building
