Q1. A user has set up their corporate email account on their smartphone. They want to ensure that all their email folders, not just the inbox, are synchronized. What setting should they adjust?
Answer: C. Folder sync settings
Adjusting the folder synchronization settings in the mail application allows users to select specific folders beyond the inbox for continuous updates. While IMAP supports multiple folders, you must still manually enable syncing for them on mobile devices.
Q2. A business professional frequently travels with a laptop that has only two USB-C ports. They need to connect a USB-A flash drive, an HDMI monitor, and charge their laptop simultaneously. Which device would best suit their needs?
Answer: C. Port replicator with USB-C
A USB-C port replicator provides multiple connection types like USB-A, HDMI, and power passthrough through a single laptop port. Individual adapters would quickly exhaust the two available ports.
Q3. A user of a 3-D printer notices inconsistent printing results. What maintenance steps should they take to improve print quality?
Answer: C. Replace filament and ensure the print bed is level and clean
Maintaining a 3-D printer requires replacing degraded filament and ensuring the print bed is completely clean and level. The other options describe maintenance steps for thermal, impact, or laser printers, which use entirely different consumables.
Q4. A technician is troubleshooting a computer and needs to check the power supply output voltages. Which voltages are commonly provided by a standard computer power supply?
Answer: A. 3.3V, 5V, and 12V
Standard desktop power supplies provide 3.3V, 5V, and 12V outputs to run motherboard logic, drives, and processors. High voltage options like 110V are main power inputs, not internal direct current outputs.
Q5. A company wants to archive important documents and distribute them to clients in a physical format. Which type of removable storage is suitable for long-term archiving and distribution?
Answer: C. Optical drive (CD/DVD/Blu-ray)
Optical media like Blu-ray discs provide inexpensive, reliable, write-once storage ideal for permanent archiving. Flash drives and external hard drives are easily overwritten or corrupted, making them less secure for strict long-term preservation.
Q6. A user is building a high-speed gaming computer and wants the fastest available storage option. Which SSD interface should they choose for the best performance?
Answer: B. NVMe
NVMe over PCIe provides the highest performance for SSDs, offering significantly faster read and write speeds compared to older interfaces. For the exam, remember that NVMe is the protocol of choice for high-speed gaming and workstation builds.
Q7. A network administrator notices that network speed drops significantly during work hours. What should be their initial step in troubleshooting this issue?
Answer: B. Check if there are any environmental or infrastructure changes recently made
Troubleshooting methodology requires establishing a theory of probable cause before implementing changes. Checking for recent environmental or infrastructure changes is a standard first step that correctly identifies the root cause without creating unnecessary network disruptions.
Q8. A technician is setting up a console connection to configure a network switch. Which type of cable is traditionally used for this purpose?
Answer: C. Serial
Serial cables, typically using RS-232 standards, are traditionally used for console connections to configure network switches. While modern switches often support USB ports for configuration, serial remains the classic standard tested on the exam.
Q9. A security analyst needs to monitor and analyze network traffic for security assessments without interrupting the flow of data. Which tool should they use?
Answer: A. Network tap
A network tap provides a copy of network traffic for monitoring without interrupting the flow of data, making it perfect for security analysis. A loopback plug tests port functionality by reflecting outgoing signals back into the device.
Q10. A technician needs to prepare Ethernet cables by removing their outer insulation without damaging the internal wires. Which tool is best suited for this task?
Answer: B. Cable stripper
A cable stripper removes the outer insulation from Ethernet cables without damaging the internal twisted pairs. A crimper is used afterwards to attach the RJ-45 connector firmly to the exposed wires.
Q11. A user wants to connect their smartphone, smartwatch, and Bluetooth headphones in a short-range, personal network. What type of network fits this scenario?
Answer: B. PAN (Personal Area Network)
A Personal Area Network, or PAN, connects devices within a short range of a single person, typically using Bluetooth. Local Area Networks cover larger physical spaces like homes or offices and are not tied to a single user.
Q12. A remote employee needs to securely access the company's internal network and resources over the internet. What technology should the company use to provide secure access?
Answer: C. VPN (Virtual Private Network)
A Virtual Private Network creates an encrypted tunnel over the internet, allowing remote users to securely access internal company resources. VLANs only segment physical network switches and do not secure traffic over the internet.
Q13. A company is setting up its email infrastructure and wants to ensure that incoming emails are directed to their mail server. Which type of DNS record is used to specify the mail server responsible for accepting email messages on behalf of…
Answer: B. MX record
An MX record directs email to a specific mail server responsible for accepting messages on behalf of a domain. An A record only maps a domain name to a standard IPv4 address.
Q14. A network engineer is configuring a network that needs a larger address space due to the number of devices. Which IP addressing should they use?
Answer: B. IPv6
IPv6 provides a vastly larger address space than IPv4, making it necessary for networks with an enormous number of connected devices. APIPA is used for automatic local addressing when a DHCP server fails.
Q15. A website with high traffic volumes is experiencing slow response times during peak hours. Which internet appliance can help distribute the traffic evenly across multiple servers to improve website performance?
Answer: D. Load balancer
A load balancer distributes incoming network traffic across multiple servers to prevent bottlenecks and improve overall performance. A proxy server primarily forwards web requests and caches data, but does not actively balance server loads.
