Q1. An IT technician is setting up a server for transferring files within a corporate network. Which ports should they ensure are open to facilitate non-secure FTP traffic?
Answer: A. 20/21
Ports 20 and 21 are used for File Transfer Protocol (FTP). Port 20 is used for data transfer, while port 21 is used for control (commands). These ports should be open for FTP traffic.
Q2. A web developer is creating a website that does not require encrypted data transmission. Which port should they ensure is open for standard HTTP traffic?
Answer: C. 80
Port 80 is used for standard, unencrypted Hypertext Transfer Protocol (HTTP) traffic, commonly used for websites that do not require encrypted data transmission.
Q3. A user is accessing a secure online banking website. Which port is used for this secure web traffic, encrypted via Hypertext Transfer Protocol Secure (HTTPS)?
Answer: B. 443
Port 443 is used for HTTPS, which is the secure version of HTTP. This protocol encrypts the data transferred between the user's browser and the website, making it essential for secure transactions like online banking.
Q4. In a small home office, there is a need to share a single internet connection among multiple devices wirelessly. Which device is most appropriate?
Answer: A. Router
A wireless router is the correct choice because it routes traffic between the internet and local devices while providing Wi-Fi connectivity. Hubs and repeaters do not route traffic or assign IP addresses, and a bridge simply connects two network segments.
Q5. A user wants to connect a wireless keyboard and mouse to their computer. Which wireless technology is commonly used for short-range device-to-device communication in peripherals like keyboards and mice?
Answer: B. Bluetooth
Bluetooth is the correct answer because it is the standard short-range wireless protocol for peripherals like keyboards and mice. Wi-Fi is used for network connectivity, while NFC and RFID are used for close proximity identification tasks.
Q6. A business is upgrading its wireless network to support a higher number of devices with improved efficiency and bandwidth. Which latest IEEE 802.11 standard should they implement?
Answer: B. 802.11ax (WiFi 6)
The 802.11ax standard, also known as Wi-Fi 6, is correct because it is specifically designed to handle high-density environments with improved efficiency. Older standards like 802.11ac do not manage multiple simultaneous device connections as efficiently.
Q7. A company needs to collect and analyze logs from various network devices to monitor and troubleshoot network issues. Which type of server should they implement for this purpose?
Answer: B. Syslog server
A syslog server is the correct answer because it is specifically designed to collect and centralize log messages from network devices for troubleshooting. Web, print, and DHCP servers handle their own specific services but do not aggregate logs.
Q8. A user's computer is unable to obtain an IP address from the DHCP server. The computer automatically assigns itself an IP address. Which type of addressing is the computer using?
Answer: C. APIPA
APIPA is the correct answer because a client automatically assigns itself an address in the 169.254 range when it cannot reach a DHCP server. Dynamic and static addressing both require manual or server intervention to configure properly.
Q9. A network administrator is troubleshooting WiFi performance issues in an office. They need to identify overcrowded WiFi channels. Which tool should they use?
Answer: B. WiFi analyzer
A WiFi analyzer scans the wireless spectrum to display nearby access points and their channel usage. Technicians use this data to identify overcrowded channels, whereas cable testers and loopback plugs evaluate physical wired connections.
Q10. A user wants to connect a laptop to a monitor for high-definition video and audio output. Which two types of cables are suitable for this purpose?
Answer: B. HDMI and DisplayPort
HDMI and DisplayPort carry both high-definition video and audio signals. VGA and DVI primarily support analog or digital video only, while USB standards require alternate modes to handle native display output.
Q11. A user has a new laptop and smartphone, both of which support charging and data transfer through the same type of port. Which type of connector is likely used by both devices?
Answer: C. USB-C
USB-C is a versatile connector found on modern laptops and smartphones that handles both data transfer and charging. Older formats like microUSB lack the universal power delivery capabilities expected in newer devices.
Q12. A server in a data center requires RAM that can detect and correct common kinds of internal data corruption. Which type of RAM is specifically designed for this purpose?
Answer: D. ECC RAM
Error Correction Code memory detects and fixes internal data corruption, making it essential for servers. Standard DDR4 or SODIMM modules lack this built-in error checking, leaving them vulnerable to silent data corruption.
Q13. A company needs to build a high-performance computing system for complex simulations. What feature should they look for in a motherboard to support multiple CPUs?
Answer: C. Multisocket capability
Multisocket capability allows a motherboard to house more than one physical processor. This feature is strictly required to install multiple CPUs in high-performance computing systems, whereas dual-channel memory is a common but unrelated specification.
Q14. A hiking enthusiast wants to use a GPS tracking app to map their trail, but they will be in an area with no cellular service. What aspect of their smartphone should they ensure is functional to use GPS services?
Answer: B. GPS receiver in the smartphone
For a GPS tracking app to function properly in an area with no cellular service, the smartphone must have a functional GPS receiver. GPS receivers do not rely on cellular networks and can receive signals directly from GPS satellites.
Q15. A user wants to ensure that all photos taken with their smartphone are automatically backed up to their Google Workspace account. Which feature should be enabled on their device?
Answer: B. Google Photos backup
Enabling Google Photos backup in the Google Workspace account settings on a smartphone will automatically upload and store photos taken with the device. This feature provides an easy and efficient way to back up photos to the cloud.
Q16. A company's IT specialist is tasked with enhancing the security of their website to protect user data during transmission. The website currently uses HTTP. To encrypt and secure the traffic between the user's browser and the website, which…
Answer: B. Convert the website from HTTP to HTTPS by installing an SSL/TLS certificate
Installing an SSL/TLS certificate converts a website to HTTPS, encrypting data between the browser and server. WPA2 only secures the local Wi-Fi link, while a firewall filters traffic but does not encrypt the end-to-end web session.
Q17. You are preparing to install a new network cable and need to expose the internal wires for termination. Which tool is best suited for removing the outer insulation without damaging the wires?
Answer: A. Cable stripper
A cable stripper is specifically designed to score and remove the outer jacket of a network cable without nicking the internal wires. A punchdown tool terminates wires, and wire cutters risk damaging the conductors during preparation.
