What are the key principles to consider when designing a data centre?

• Accessibility

• Affordability

• Scalability, Redundancy, Energy Efficiency, Security, Cooling

• Flexibility

Explain the importance of effective data centre operations management.

• Effective data centre operations management is only important for large organizations.

• Data centre operations management has no impact on IT infrastructure.

• Optimizing resource utilization is not a key aspect of data centre operations management.

• Effective data centre operations management is important for maintaining IT infrastructure, minimizing downtime, optimizing resource utilization, enhancing security, and meeting business objectives.

What are some best practices for ensuring data centre security?

• Never update software or security patches

• Leave data centre doors unlocked at all times

• Share sensitive data openly on public forums

• Implement strong access controls, regularly update software and security patches, conduct regular security audits and assessments, encrypt sensitive data, monitor network traffic for anomalies, and implement multi-factor authentication.

Describe the different types of cooling systems used in data centres.

• Air cooling, liquid cooling, and immersion cooling

• Fan cooling, phase-change cooling, and convection cooling

How is power distribution managed in a data centre environment?

• Solar panels, wind turbines, and geothermal energy are used for power distribution in a data centre environment.

• Water sprinklers, air conditioning, and soundproofing are used for power distribution in a data centre environment.

• Candles, oil lamps, and torches are used for power distribution in a data centre environment.

• UPS systems, PDUs, and backup generators are used for power distribution in a data centre environment.

Why is disaster recovery planning crucial for data centres?

• Disaster recovery planning is crucial for data centres to ensure business continuity, minimize downtime, protect critical data, and maintain operations during emergencies.

• Disaster recovery planning only applies to non-critical data in data centres

• Data centres can easily recover from disasters without any planning

• Disaster recovery planning is unnecessary and a waste of resources for data centres

What factors should be considered when designing a data centre layout?

• Type of flooring

• Number of windows

• Color of the walls

• Power and cooling requirements, physical security, scalability, network connectivity, equipment placement, and redundancy.

How can data centre operations be optimized for efficiency?

• Ignore monitoring systems

• Increase manual data entry

• Use outdated hardware

• Implement virtualization, use energy-efficient hardware, employ automation, monitor cooling systems, and optimize storage and network configurations.

What are some common security threats to data centres and how can they be mitigated?

• Ignore security training for staff

• Use outdated security software

• Implement strong access controls, regularly update security patches, conduct security training for employees, use encryption for sensitive data, and implement multi-factor authentication.

• Share passwords among employees

Compare and contrast air-based and liquid-based cooling systems in data centres.

• Air-based systems are more efficient but can be more expensive and complex

• Air-based cooling systems use liquid coolant

• Liquid-based systems are easier to install and maintain

• Air-based cooling systems use air for heat dissipation, while liquid-based cooling systems use liquid coolant. Air-based systems are easier to install and maintain, while liquid-based systems are more efficient but can be more expensive and complex.
