Cisco Cyber Security Practice Exam

Which types of power issues should a technician be concerned about?

1. Blackout, Brownout, Spike

2. Spike, Flood, Power Surge

3. Surge, Flicker, Diminish

4. Brownout, Flicker, Surge

The correct answer is: Blackout, Brownout, Spike

A technician should be particularly concerned about blackouts, brownouts, and spikes because these power issues can significantly impact the operation and reliability of computer systems and sensitive electronic equipment. A blackout refers to a complete loss of power, which can lead to data loss, hardware damage, and interruption in service. This is especially critical in environments that require continuous power availability, such as data centers or critical infrastructure facilities. A brownout is characterized by a temporary drop in voltage levels, which can cause equipment to operate inefficiently or, in some cases, lead to damage if the equipment is not designed to handle such fluctuations. This is concerning because it can result in performance degradation and increased wear on components over time. A spike is a sudden increase in voltage that can occur due to various factors, such as lightning strikes or power redistribution. These spikes can cause immediate damage to electronic components and disrupt system functionality, making them a significant risk for technicians to manage. Understanding these specific power issues helps technicians to implement appropriate protective measures, such as uninterruptible power supplies (UPS), surge protectors, and voltage regulators, ultimately maintaining the stability and security of the systems they support.
