A technician is troubleshooting a problem. The technician tests the theory and determines the theory is confirmed. Which of the following should be the technician’s NEXT step?
Correct Answer: C
Explanation:
The technician’s next step after testing the theory and determining the theory is confirmed is to establish a plan of action to resolve the problem and identify potential effects. This step involves preparing a specific method to implement the solution and considering how the solution might affect other components or users. The technician should also test the plan in an isolated environment before applying it to the actual system. Implementing the solution is not the next step after testing the theory and determining the theory is confirmed, as it requires establishing a plan of action first. Documenting lessons learned is not the next step after testing the theory and determining the theory is confirmed, as it comes after verifying full system functionality and implementing preventive measures. Verifying full system functionality is not the next step after testing the theory and determining the theory is confirmed, as it comes after implementing the solution.
Question 2
A company executive wants to view company training videos from a DVD. Which of the following components would accomplish this task?
Correct Answer: A
Explanation:
An optical drive is a component that can accomplish the task of viewing company training videos from a DVD. An optical drive is a device that can read and write data from optical discs, such as CDs, DVDs, or Blu-ray discs. An optical drive uses a laser beam to access the data stored on the disc. An optical drive can play video or audio files from optical discs, as well as install software or store data. A hard disk drive (HDD) is a component that can store large amounts of data on magnetic platters, but it cannot read or write data from optical discs. A solid state drive (SSD) is a component that can store data on flash memory chips, but it cannot read or write data from optical discs. A flash drive is a component that can store data on flash memory chips and connect to a USB port, but it cannot read or write data from optical discs.
Question 3
A UPS provides protection against:
Correct Answer: C
Explanation:
A UPS (uninterruptible power supply) provides protection against power outages by providing
backup power to connected devices in case of a power failure. A UPS typically consists of a battery,
an inverter, and a surge protector. A UPS can prevent data loss, hardware damage, or downtime
caused by sudden loss of electricity. A UPS can also protect against power surges, spikes, or
fluctuations that can harm electronic devices.
A denial of service (DoS) is a cyberattack that attempts to disrupt the normal functioning of a
network or system by overwhelming it with traffic or requests. A UPS does not provide protection
against DoS attacks, as they target the network layer, not the physical layer. A replay attack is a cyberattack that involves intercepting and retransmitting data to impersonate or deceive another party. A UPS does not provide protection against replay attacks, as they target the application layer, not the physical layer. Wiretapping is the act of secretly monitoring or recording the communication or data transmission of another party. A UPS does not provide protection against wiretapping, as it does not encrypt or secure the data.
