Q1. A user needs to charge their Apple iPhone and transfer data between their phone and computer. Which type of connector is typically used for this purpose in newer iPhone models?
Answer: C. USB-C
Newer Apple iPhone models utilize USB-C connectors to meet European regulatory standards for charging and data transfer. Previous models relied on the proprietary Lightning port, but you must select USB-C when questions specify the newest Apple hardware.
Q2. A company is planning to install a network that will support Gigabit speeds and possibly higher in the future. Which category of Ethernet cable should they use for future-proofing their network?
Answer: C. Cat 6
Cat 6 cabling safely supports 10 Gbps speeds over limited distances and handles Gigabit speeds effortlessly, making it an excellent choice for future-proofing a network. Cat 5e only officially supports standard Gigabit throughput, providing no real upgrade path for 10 Gigabit hardware.
Q3. A company requires a high-speed internet connection with large bandwidth to support their data-intensive applications. Which type of internet connection should they consider?
Answer: B. Fiber
Fiber optic internet provides exceptional bandwidth and symmetrical speeds, easily outperforming DSL, satellite, or cellular connections for heavy data transfers. Its dedicated infrastructure makes it the optimal choice for enterprise environments continuously running intensive applications.
Q4. A business plans to host its own website to provide information about its services. Which server role is necessary to host this website?
Answer: C. Web server
A web server is specifically designed to host websites. It stores, processes, and delivers web pages to users' browsers. For a business wanting to host its own website, setting up a web server is essential.
Q5. A network administrator is configuring a server that will translate domain names into IP addresses to facilitate internet browsing. Which server role should they configure?
Answer: B. DNS server
A DNS server translates domain names into IP addresses, which is essential for internet browsing as it allows users to access websites using familiar domain names rather than numeric IP addresses.
Q6. A telecommunications company is deploying a long-range wireless network for a rural area and requires exclusive use of certain frequencies to avoid interference. What type of spectrum should they use?
Answer: B. Licensed spectrum
A licensed spectrum is the correct choice because it grants exclusive rights to specific frequencies, which is crucial for avoiding interference in commercial deployments. Unlicensed bands, like 2.4GHz, do not provide this guarantee and can become congested.
Q7. A technician notices that a computer does not complete its boot process and emits a series of beeps. What component should they check first?
Answer: D. RAM
Beeper codes indicate a failed power on self test, and RAM is the most common culprit for these alerts. While the speaker is on the motherboard, the motherboard itself is rarely the first component to check for a beep code.
Q8. A user is experiencing poor battery life and slow performance on their smartphone. Which TWO of the following actions could potentially resolve these issues?
Answer: A,B. Replacing the battery || Clearing the cache
Replacing a degraded battery directly resolves poor battery life, and clearing the cache can improve sluggish device performance. Updating the operating system is another strong fix for slow performance, making the choices debatable.
Q9. You suspect a malfunctioning power supply in a desktop computer. Which tool would you use to test the voltage of the power supply?
Answer: B. Multimeter
A multimeter accurately measures voltage, current, and resistance, making it the ideal tool for testing a power supply. However, a dedicated power supply tester is also valid for quickly checking voltage rails, making this question slightly ambiguous despite the multimeter's versatility.
Q10. A user in a developed urban area finds that their smartphone frequently switches from 5G to 4G LTE. What is the most likely reason for this?
Answer: C. 5G coverage is not consistently available in the area
Devices automatically drop down from 5G to 4G LTE when the 5G signal becomes too weak. A damaged antenna is a hardware failure that would usually prevent all cellular connections, not just a seamless downgrade to a lower network tier.
Q11. After updating their smartphone, a user finds that some apps no longer work. What is the most likely reason?
Answer: A. The apps are not compatible with the new OS version
Major operating system upgrades frequently break application compatibility until developers release matching updates. Battery level or Wi-Fi stability would not specifically cause applications to stop functioning immediately following a system update.
Q12. A user complains that during phone calls, the person on the other end cannot hear them clearly, but voice recording apps seem to work fine. What is the most likely cause of this issue?
Answer: B. Software-related issue
Since the microphone captures audio perfectly in voice recording apps, the hardware is functioning normally. This isolates the failure to a software bug, such as a calling application lacking proper microphone permissions.
Q13. A user complains that their smartphone's screen is not visible under direct sunlight. Which type of display technology is likely used in their phone?
Answer: C. TFT LCD
Older TFT LCD panels typically suffer from poor contrast and low brightness, making them wash out easily in direct sunlight. Modern OLED screens achieve much higher contrast and brightness for far better outdoor visibility.
Q14. A laptop user reports several keys are not working. After troubleshooting, you decide to replace the keyboard. What should you consider first when selecting a replacement keyboard?
Answer: B. The layout and size of the keyboard
Laptop keyboards feature proprietary layouts, ribbon cable placements, and specific form factors that must match the chassis perfectly. Backlighting and color are secondary cosmetic features compared to ensuring the physical dimensions align correctly.
Q15. In a small office, employees need to print documents from different computers to a single office printer. Which feature should be enabled on the network to facilitate this?
Answer: A. Printer share
Enabling printer sharing on the host computer allows multiple network users to send print jobs to that locally attached device. However, a dedicated print server or network-attached printer is the more robust enterprise option, creating slight ambiguity for a corporate setting.
Q16. A user is experiencing discomfort in their wrist while using their laptop's trackpad for extended periods. Which alternative input device would likely reduce their discomfort?
Answer: B. External mouse
Connecting an external mouse provides a more ergonomic hand position and relieves the unnatural wrist strain caused by trackpads. An external keyboard alone does not replace the repetitive trackpad motions causing the discomfort.
