A technician is setting up a projector for a videoconferencing system. When the user attempts to connect a laptop to the system, the system displays the following error message:
no source found
The user tries multiple cables and inputs on the projector Which of the following should the user try next?
The user should check the display settings on the computer and set them to extend/duplicate. This will allow the computer to send the video signal to both the laptop screen and the projector. If the display settings are set to only show on one screen, then the projector may not detect any source. According to the CompTIA Core1 objectives, one of the common display issues is no image on screen. A troubleshooting guide for projectors also suggests checking the display settings as a possible solution for no source found error.
A customer's phone no longer charges fully The phone only charges to 67% and then stops_ Which of the following should be replaced to resolve this issue?
The correct answer is C. The battery.
The battery is the component that stores and provides electrical power to the phone. The battery can degrade over time and lose its capacity to hold a full charge. This can cause the phone to stop charging at a certain percentage and run out of power faster. To resolve this issue, the battery should be replaced with a new one that is compatible with the phone model and manufacturer.
To replace the battery, the customer may need to follow different steps depending on the type of phone and battery. Some phones have removable batteries that can be easily accessed by opening the back cover of the phone and sliding out the old battery. Other phones have non-removable batteries that are sealed inside the phone and require special tools and skills to open the phone and disconnect the old battery. In this case, the customer may need to contact the phone manufacturer or a professional service center for assistance.
A technician is installing a storage solution for a computer that requires data redundancy with the fewest drives possible. Which of the following would best meet this requirement?
Vertical streaks are appearing on the output of a laser printer. Which of the following items is the MOST likely cause?
Vertical or horizontal lines---Marks that appear in the same place (referred to as repetitive defects) are often due to dirty feed rollers (note that there are rollers in the toner cartridge and fuser unit too) or a damaged or dirty photosensitive drum.
Vertical streaks on a laser printer output are usually caused by a damaged or worn-out drum, which is responsible for transferring toner to the paper. If the drum is damaged, toner may accumulate on certain parts of the drum, leading to streaks on the printed output.

A technician is replacing the toner cartridge in a laser printer. Which of the following steps should the technician complete first? (Select two).
The technician is unable to access the company portal website, but other websites work fine. This suggests an issue with resolving the specific URL of the company portal, which is a function of DNS.
Here's why other options are not the most likely cause:
DHCP reservations:This is not relevant as the issue persists even when the technician tries a different workstation,indicating a problem beyond individual device configuration.
Static IP addresses:Similar to DHCP reservations,static IPs are not likely the cause as both affected workstations are experiencing the issue.
Default gateway:While the default gateway is necessary for internet access,other websites are working,making it less likely to be the root cause.
