An IT support specialist needs to configure several laptops to access local resources wherever the employees are while in the office. Which of the following would best meet this requirement?
A. Configure cellular location services to facilitate device identification.
B. Set up a Wi-Fi connection with a common SSID.
C. Enable Bluetooth connectivity in all laptops.
D. Create roaming profiles for each laptop.
Show Answer
Correct Answer: B
Explanation: A common Wi-Fi SSID allows laptops to connect seamlessly to the organization's wireless network throughout the office, providing access to local resources regardless of location. Cellular location services and Bluetooth do not provide LAN access, and roaming profiles relate to user settings, not network connectivity.
Question 52
Users have noticed their devices are frequently disconnecting or experiencing slow speeds in the company lobby, but the Wi-Fi signal is strong. Which of the following is the first step to troubleshoot the issue?
A. Increase the number of access points throughout the building to boost the overall signal strength.
B. Inspect the area for possible sources of interference or physical obstructions that could be disrupting the signal.
C. Recommend that all affected users switch to a wired connection to avoid wireless instability.
D. Change the wireless network frequency from 2.4GHz to 5GHz to enhance the connection stability and speed.
Show Answer
Correct Answer: B
Explanation: A strong Wi-Fi signal with poor performance or frequent disconnects commonly indicates interference, congestion, or environmental factors rather than insufficient signal strength. The first troubleshooting step is to inspect the area for sources of RF interference or physical conditions affecting connectivity before making configuration changes or adding hardware.
Question 53
A user's computer can connect to internal network resources but cannot access websites on the internet. Other users on the same network do not have this issue. Which of the following should a technician do first to troubleshoot the issue?
A. Verify the computer's DNS settings.
B. Replace the network cable.
C. Restart the DHCP server.
D. Adjust the firewall rules on the router.
Show Answer
Correct Answer: A
Explanation: The computer can reach internal network resources, indicating the local network connection is functioning. Because the issue is isolated to one device and affects only internet website access, DNS misconfiguration is the most likely first thing to verify. Replacing the cable is unlikely since LAN connectivity works, restarting the DHCP server would affect other clients and is not warranted for a single-host issue, and router firewall rules would typically impact multiple users rather than one device.
Question 54
Which of the following requires the connector to be attached in a specific orientation?
A. HDMI
B. USB-C
C. Lightning
D. Coaxial
Show Answer
Correct Answer: D
Explanation: USB-C and Lightning are reversible connectors. HDMI has a keyed shape but can only be inserted one way due to its trapezoidal design; however, the connector itself does not have an 'orientation' like reversible vs non-reversible in typical exam wording. A coaxial connector must be aligned correctly with its center conductor and, for threaded types such as F-type, attached in the proper orientation and then secured, making D the best match.
Question 55
A developer needs to test a new software application in multiple, diverse environments. The company wants to use the least-expensive testing method but still get the full experience of the target environments. Which of the following should the developer use?
A. Containers
B. Dual boot
C. Type 2 hypervisor
D. Sandbox
Show Answer
Correct Answer: C
Explanation: A Type 2 hypervisor allows a developer to run multiple full operating systems as virtual machines on a single host, providing the full experience of diverse target environments at much lower cost than separate physical systems. Containers are lightweight and inexpensive but share the host OS kernel, so they do not provide full OS diversity. Dual boot only runs one OS at a time, and a sandbox is an isolated environment rather than a way to emulate multiple full operating systems.
Question 56
Which of the following DNS records displays the destination of incoming email on a domain?
A. CNAME
B. TXT
C. MX
D. AAAA
Show Answer
Correct Answer: C
Explanation: An MX (Mail Exchanger) record specifies the mail server(s) responsible for receiving incoming email for a domain. CNAME creates an alias, TXT stores arbitrary text (often used for SPF/DKIM/verification), and AAAA maps a hostname to an IPv6 address.
Question 57
A company purchases a new printer for an international office. When a technician installs the printer, the display only shows a white screen. Which of the following should the technician do to troubleshoot the issue?
A. Check network port connectivity.
B. Verify the printer's power requirements.
C. Ensure the printer is in the correct organizational unit.
D. Upgrade the printer's firmware.
Show Answer
Correct Answer: B
Explanation: A white screen during initial installation indicates a hardware startup issue rather than a network, directory, or management problem. The key clue is that the printer is being installed in an international office, where mains voltage and power standards may differ by region. Verifying that the printer matches the local power requirements (or is correctly configured for the local voltage) is the appropriate first troubleshooting step. Firmware upgrades require a functioning device, and network connectivity or organizational units would not cause a blank display.
Question 58
Which of the following devices forwards traffic based on MAC addresses?
A. Switch
B. Router
C. Firewall
D. Gateway
Show Answer
Correct Answer: A
Explanation: A switch forwards Ethernet frames based on MAC addresses using its MAC (CAM) address table. Routers forward traffic based on IP addresses, while firewalls filter traffic according to security rules and gateways connect dissimilar networks or protocols.
Question 59
A developer wants to ensure that their critical data is protected from a hard drive failure. Their workstation has two hard drives. Which of the following should the developer use for their workstation?
A. RAID 0
B. RAID 1
C. RAID 5
D. RAID 10
Show Answer
Correct Answer: B
Explanation: RAID 1 mirrors data across two drives, providing redundancy so the system can tolerate a single drive failure without data loss. RAID 0 provides no redundancy, RAID 5 requires at least three drives, and RAID 10 requires at least four drives.
Question 60
A user's wireless headset shows a "connected" status when turned on, but the Bluetooth list on the user's phone shows that the headset is "not connected." Which of the following should the technician do?
A. Enter the PIN.
B. Turn off Wi-Fi.
C. Re-pair the devices.
D. Enable Bluetooth.
Show Answer
Correct Answer: C
Explanation: If the headset indicates it is connected but the phone shows it is not connected, the pairing relationship is likely stale or corrupted. Re-pairing the devices is the standard troubleshooting step. Entering a PIN is only needed during pairing if prompted, Wi-Fi does not affect Bluetooth pairing in this scenario, and Bluetooth is already enabled since the phone can detect the headset.
