 Class K fires involve cooking oils and fats, which are highly combustible and can ignite quickly at high temperatures. To suppress a Class K fire, a specific type of extinguishing agent is required that can separate and absorb the heat elements of the fire – the fuel, oxygen, and heat necessary to start a fire. Foam extinguishers are most suitable for Class K fires because they use a substance that turns oils into foam, effectively smothering the fire and preventing re-ignition. Water should not be used on Class K fires as it can cause the oil to splatter and spread the fire. Carbon dioxide and dry chemical extinguishers are also not recommended for Class K fires as they do not adequately remove the heat from the fire.

A True Online UPS is designed to provide continuous, uninterrupted power supply to equipment. It has a pair of inverters and converters that work together to continuously charge the battery and convert the battery’s DC power back to AC power for the equipment. This ensures that there is zero transfer time to the battery when power is lost, providing the most reliable power for sensitive equipment and critical applications that cannot tolerate any interruption in power. Kyle’s choice of a True Online UPS is appropriate for ensuring that the servers, which store confidential data and run applications, are not affected by unreliable power sources.

References: The Certified Network Defender (CND) program by EC-Council includes the study of various types of UPS systems as part of its module on Business Continuity and Disaster Recovery. The program outlines the importance of maintaining power to critical systems and the role of a True Online UPS in providing the highest level of protection against power inconsistencies12.

WPA5 is not a standard term used in the industry, and there seems to be a confusion or typo in the question. However, based on the context of Wi-Fi security and encryption, the closest relevant standard is WPA3, which uses AES-GCMP 256 as its encryption algorithm. WPA3 is the successor to WPA2 and provides enhanced security features. It uses the Advanced Encryption Standard (AES) with Galois/Counter Mode Protocol (GCMP) 256-bit encryption, which offers a higher level of security than the previous encryption methods used in WPA2, such as AES-CCMP. AES-GCMP 256 provides robust protection against various attacks and is designed to work efficiently on a wide range of devices, including those with limited processing capabilities.

Implementing access control mechanisms like a firewall is a preventive measure in network defense. The preventive approach focuses on establishing barriers and safeguards to stop security incidents before they occur. Firewalls are a core component of this strategy, as they control incoming and outgoing network traffic based on predetermined security rules, thereby preventing unauthorized access to or from a network.

References: The Certified Network Defender (CND) program emphasizes a multi-layered defense strategy, which includes the Protect, Detect, Respond, and Predict framework. Within this framework, the Protect phase aligns with the preventive approach, as it involves the implementation of security measures that aim to prevent threats from compromising the network1. This is further supported by the NIST Cybersecurity Framework, which outlines Identify, Protect, Detect, Respond, and Recover as the five core functions for a comprehensive cybersecurity approach2.
