A technician is troubleshooting a laptop that has a blank LCD panel. The technician shines a flashlight into the LCD and sees a faint image.
Which of the following BEST describes the issue?
- A . Defective inverter
- B . Incomplete video driver
- C . Incorrect input source
- D . Burned-out bulb
A
Explanation:
an inverter is a device that converts DC power from the laptop’s battery or AC adapter to AC power for the backlight of the LCD panel. If the inverter is defective, the backlight will not work and the LCD panel will appear blank or very dim. The user can still see a faint image if they shine a flashlight into the LCD because the LCD itself is still working.
A technician is on site troubleshooting a customer’s laptop. The technician needs to download a software update but the company’s proxy is blocking updates.
Which of the following would be the MOST appropriate action for the technician to take to get the update?
- A . Connect to a hotspot
- B . Request a traffic exemption.
- C . Change the DNS address to 1.1.1.1
- D . Update the Group Policy settings
B
Explanation:
If a technician is on site troubleshooting a customer’s laptop and needs to download a software update but the company’s proxy is blocking updates, the most appropriate action for the technician to take would be to request a traffic exemption from the company’s IT department.
A technician installed a new router at a small office. After the Installation, the technician notices that all devices have a I69.254.x.x IP address. Printers and fileshares are still working, but PCs cannot access the Internet.
Which of the following should the technician configure on the router to enable devices to connect to the internet?
- A . APIPA
- B . DNS
- C . DHCP
- D . SMB
C
Explanation:
To enable devices to connect to the internet after installing a new router at a small office, the technician should configure DHCP (Dynamic Host Configuration Protocol) on the router. DHCP is a network protocol that automatically assigns IP addresses and other network configuration parameters to devices on a network. By configuring DHCP on the router, the technician can ensure that all devices on the network are assigned a valid IP address that allows them to connect to the internet.
If all devices have a 169.254.x.x IP address, this suggests that the router is not assigning IP addresses to the devices using DHCP (Dynamic Host Configuration Protocol). Configuring the DHCP settings on the router can enable the devices to receive IP addresses automatically and access the internet.

A user submits a help desk ticket regarding a smartphone that will no longer accept its charging cable. The assigned technician notices the phone does not have a protective case, and the user constantly transport the phone in a pocket. The technician attempts to use a secondary charger, but the cable falls out of the phone.
Which of the following is the MOST likely cause of the issue?
- A . The phone requires a firmware update to address charging issues.
- B . The charge port contains foreign objects, such as lint.
- C . The phone’s battery has swelled, preventing the utilization of the charge port.
- D . The phone has experienced water damage, thus the battery is not charring.
B
Explanation:
The symptoms suggest that the charging cable falls out of the phone, indicating that the charge port may contain foreign objects such as lint, which can interfere with the connection between the charging cable and the phone.
A desktop support technician is tasked with upgrading a laptop so that it has the fastest data access possible.
Which of the following BEST satisfies this requirement?
- A . mSATASSD
- B . M.2NVMeSSD
- C . 2.5SATASSD
- D . 2.5SASHHD
B
Explanation:
M.2 NVMe SSD provides the fastest data access possible for a laptop. It is a high-performance solid-state drive that connects directly to the motherboard through an M.2 slot.
A user requested upgrades to a company-issued laptop to increase its performance while working with a large database stored on drive C.
Which of the following tasks should a systems administrator complete to BEST meet this goal? (Select TWO).
- A . Configure RAID 1.
- B . Install a hybrid drive.
- C . Upgrade to 1GB NIC.
- D . Increase the RAM.
- E . Migrate to a SSD.
- F . Upgrade the power supply.
D,E
Explanation:
To increase the performance of a laptop working with a large database stored on drive C, a systems administrator should increase the RAM and migrate to an SSD. Increasing the RAM will help the laptop to better handle the large database, while migrating to an SSD will improve the speed at which the laptop can access the database. Configuring RAID 1, installing a hybrid drive, upgrading to a 1GB NIC, and upgrading the power supply will not directly improve the laptop’s performance when working with a large database.

A user’s computer is not receiving a network connection. The technician confirms that the connection seems to be down and looks for the user’s port on the patch panel. The port and patch panel are not labeled.
Which of the following network tools should the technician use to identify the port?
- A . Network tap
- B . Punchdown tool
- C . Toner probe
- D . Crimper
C
Explanation:
Toner Probe Many cable testers also incorporate the function of a toner probe, which is used to identify a cable from within a bundle. This may be necessary when the cables have not been labeled properly. The tone generator is connected to the cable using an RJ45 jack and applies a continuous audio signal on the cable. The probe is used to detect the signal and follow the cable over ceilings and through ducts or identify it from within the rest of the bundle.
A user’s laptop is running out of disk space and requires a new hard drive. The user wants to replace the existing hard drive with the fastest possible I TB HDD. A technician assesses the user’s hardware and determines the connections that are available.
Which of the following drive types should the technician recommend as the BEST choice?
- A . 1TB NVMe SSD
- B . 1TB flash drive
- C . 1TB SATA SSD
- D . 1TB SAS
A
Explanation:
The best choice for the user’s laptop is a 1TB NVMe SSD. NVMe (Non-Volatile Memory Express) is a high-performance storage protocol designed specifically for solid-state drives (SSDs). It is significantly faster than SATA SSDs and SAS hard drives, making it ideal for users who need fast storage for their laptop. NVMe SSDs also have lower latency and higher bandwidth than traditional hard drives, making them well-suited for data-intensive tasks such as video editing, gaming, and running multiple applications simultaneously. Additionally, NVMe offers more reliable data reliability than traditional hard drives, and is less susceptible to performance degradation over time.
