1. A technician is upgrading RAM in a desktop computer that currently has DDR4 memory. The motherboard supports both DDR4 and DDR5 memory modules. Which of the following statements is correct regarding the upgrade?

   • DDR5 is backward compatible with DDR4 slots because they share the same pin count
   • DDR4 and DDR5 modules can be mixed in the same motherboard as they both have 288 pins
   • The technician should install DDR5 modules in DDR4 slots after updating the BIOS
   • The motherboard can use either DDR4 or DDR5, but not both simultaneously due to different notch positions and electrical requirements

2. A user reports that their laptop screen is very dim even at maximum brightness settings. The laptop works properly when connected to an external monitor. What is the MOST likely cause of this issue?

   • Corrupted video drivers
   • Defective video cable connection
   • Low battery power
   • Failed backlight or inverter

3. Which of the following ports and protocols are correctly matched? (Select TWO)

   • SSH - Port 22
   • HTTPS - Port 443
   • RDP - Port 22
   • SMTP - Port 443
   • HTTP - Port 8080

4. A technician is troubleshooting a laser printer that is producing pages with a ghost image (echo) of previous prints. What is the MOST likely cause and solution?

   • The photosensitive drum's cleaning blade or erasure lamp is defective; replace the drum assembly or cleaning components
   • The printer is low on toner; replace the toner cartridge
   • The transfer roller is worn; clean or replace it

   • Replace the battery immediately
   • Factory reset the device
   • Check for background apps and processes consuming excessive CPU
