A user is having issues displaying the contents of their laptop screen on a projector. The laptop is connected using an HDMI cable, but the screen displays a message indicating there is no signal. Which of the following should the technician do first to diagnose the issue?
A. Check the projector input sources.
B. Replace the HDMI cable.
C. Change the resolution of the screen to 1080p.
D. Verify the HDMI port is not damaged.
Show Answer
Correct Answer: A
Explanation: The first troubleshooting step for a projector showing 'No Signal' is to verify that the projector is set to the correct input/source (HDMI). This is a quick, non-invasive check and a common cause of the issue. Replacing the cable, changing the display resolution, or inspecting the HDMI port are appropriate later steps if the correct input is already selected.
Question 82
A customer reports that internet browsing on their smartphone is fast at the beginning of the month but significantly slows down toward the end of the month. A technician examines the phone and finds multiple free cloud backup services running, with several gigabytes of personal data spread across each. Data availability is important to the customer. Which of the following is the best way to resolve the customer's issue?
A. Disabling all cloud backup services except one
B. Installing an additional SD card for photos and videos
C. Expanding the cache storage to consolidate data
D. Configuring data synchronization only over Wi-Fi connections
Show Answer
Correct Answer: D
Explanation: The slowdown occurring toward the end of each month strongly suggests the customer is exhausting their mobile data allowance and being throttled by the carrier. Multiple cloud backup services synchronizing several gigabytes of data can consume substantial mobile data. Since data availability remains important, disabling backups is not ideal. Restricting synchronization to Wi-Fi preserves backups while preventing background uploads from using the mobile data plan.
Question 83
Which of the following is used to register inputs on a touch-screen monitor?
A. Inverter
B. Digitizer
C. OLED
D. LCD
Show Answer
Correct Answer: B
Explanation: A touch-screen registers touch input using a digitizer layer that detects the position of touch. An inverter powers backlighting in some older LCD displays, while OLED and LCD are display technologies rather than the touch input sensing component.
Question 84
A technician receives a notification after a network outage that indicates the printer is not reachable. Which of the following printer settings should the technician implement to prevent this issue in the future?
A. Gateway
B. Static IP
C. APIPA
D. DHCP
Show Answer
Correct Answer: B
Explanation: A static IP address ensures the printer keeps the same IP address after network outages or DHCP server issues, preventing it from becoming unreachable due to address changes. A gateway setting controls routing, APIPA is only a fallback self-assigned address, and DHCP dynamically assigns addresses that may change.
Question 85
A user connects a company-issued laptop to a 4K TV but can only get 1080p resolution on the TV. The technician confirms that the laptop is capable of producing a 4K output. Which of the following the most likely cause of the issue?
A. The TV firmware is out of date.
B. The HDMI cable version is incorrect.
C. The laptop firmware is not current.
D. The CPU cannot keep up with the transcoding.
Show Answer
Correct Answer: B
Explanation: A laptop capable of 4K output that is limited to 1080p when connected to a 4K TV is most commonly caused by an HDMI cable or HDMI standard that lacks sufficient bandwidth for 4K. Outdated firmware is a less likely cause, and CPU transcoding is unrelated to directly driving an external display.
Question 86
A company policy change requires all computers to be encrypted. Which of the following technologies should a technician configure to meet this new requirement?
A. NVMe
B. RISC
C. ARM
D. TPM
Show Answer
Correct Answer: D
Explanation: TPM (Trusted Platform Module) is the hardware security module used to securely store cryptographic keys and support full-disk encryption solutions such as BitLocker. NVMe is a storage interface, while RISC and ARM are processor architectures, not encryption technologies.
Question 87
An IT specialist is setting up a new. custom computer. The specialist wants to minimize the number of power cables to keep the internal components organized and uncluttered. Which of the following power supply types should the specialist use?
A. Modular
B. Redundant
C. Linear
D. External
Show Answer
Correct Answer: A
Explanation: A modular power supply allows only the required power cables to be connected, reducing cable clutter and improving organization and airflow inside the computer case. Redundant power supplies are for high availability, linear power supplies are an older design not used for this purpose in modern PCs, and external power supplies are separate adapters, not a solution for minimizing internal cabling.
Question 88
A technician is troubleshooting a workstation that repeatedly shuts down within ten minutes of being turned on. The technician notices a loud clicking sound coming from inside the case. Which of the following components should the technician check first?
A. Exhaust fan
B. Capacitors
C. CPU fan
D. Intake fan
Show Answer
Correct Answer: C
Explanation: A workstation that shuts down after several minutes is consistent with CPU overheating. A loud clicking sound inside the case suggests a failing or obstructed fan. Among the options, the CPU fan is the most critical cooling component; if it fails, the CPU can quickly overheat and trigger an automatic shutdown. Intake or exhaust fan failures are generally less likely to cause such rapid thermal shutdowns, and bad capacitors do not typically produce a loud clicking sound.
Question 89
Which of the following is related to the creation of a secured communication channel between workstations in different locations and is supported by credentials for authentication?
A. DHCP
B. CNAME
C. VLAN
D. VPN
Show Answer
Correct Answer: D
Explanation: A VPN (Virtual Private Network) creates a secure, encrypted communication channel between devices across different locations and commonly uses credentials and other authentication methods to verify users or endpoints. DHCP assigns IP addresses, CNAME is a DNS alias record, and VLAN logically segments local networks rather than creating secure inter-site tunnels.
Question 90
A network printer does not release a user's final print job from the queue, but the user's other print jobs successfully printed a few moments before. Other users can print without issues. Which of the following should the user check first to solve the issue?
A. If the print job is configured to a tray or manual feed
B. If the computer and printer are connected to the same network
C. If the print queue is full and will not allow additional jobs
D. If the printer has stopped due to empty trays
Show Answer
Correct Answer: A
Explanation: Because earlier jobs from the same user printed successfully and other users can still print, the printer, network, and queue are generally functioning. A single final job remaining in the queue commonly indicates that the job is waiting for a resource such as a specific paper tray or manual feed setting. Checking whether the print job is configured for the wrong tray or manual feed is the appropriate first step.
