    Study Notes

    RAM Type for Desktop Computer

    • DDR3 RAM is the most likely type for a desktop computer upgrade.

    Laser Printer Streaks

    • Vertical streaks on a laser printer output are most likely caused by a faulty transfer belt.

    DVD Playback Error

    • The most likely cause of a "HDMI blocked due to Copy Protection" error when playing DVDs on a projector is that the projector does not support the HDCP protocol.

    Wireless Backhaul Channel Selection

    • A channel extremely polluted with RF signals during non-carrier-grade wireless backhaul implementation suggests a defective channel selection. Contact the manufacturer for troubleshooting.

    Laser Printer Double Images

    • A maintenance kit not installed in a year on a laser printer is most likely causing double images on printouts.

    Workstation VM Host Configuration

    • To create VMs on a workstation, enable fast startup.

    Network Connectivity Issue

    • A network connection issue might be because the port and patch panel are unlabeled. To identify the port, use a toner probe.

    Projector Audio Issue

    • If a projector has video but no audio, change the input to VGA.

    Cable Category for Network Speed

    • Cat 6a is the category that limits network transfer speed when using Gigabit LAN cards.

    Video Conferencing Webcam Issue

    • A video conferencing webcam issue can be resolved by reseating or replacing the webcam.

    Building Entrance Authentication Issue

    • The solution to a building entrance authentication issue after security measures upgrade is to enable Bluetooth or NFC on the mobile device.

    MIMO Technology Support

    • MIMO technology is supported by 802.11n standard.

    Computer Display Error

    • The "No input detected" error on a PC display can be solved by checking the power plug of the monitor and PC.

    Mobile Touchscreen Component

    • The Digitizer component enables the input on a mobile device's touchscreen.

    Computer Boot Beep Error

    • A loud beep during boot usually means the power supply is faulty

    Printer Recycling Issue

    • Leaving printed materials on the printer tray causes unnecessary recycling and would be best resolved by putting prompt reminders in the office to pick up the printer tray materials.

    Online Retailer Cloud Migration

    • Migration to public cloud for an online retailer is best described as rapid elasticity, by which capacity can be added or removed based on demand.

    Network Issue Troubleshooting

    • A network issue, where a computer cannot reach more than 100 Mbps, usually means the network cable needs replacing. Using the correct cable category (Cat 5 or higher) with the correct specifications is important.

    Laptop Screen Repair

    • A faded image on the laptop screen during repair suggests an issue with the backlight rather than the screen itself.

    Hard Drive Error Message Resolution

    • If a PC displays an error message after rebooting, it is potentially related to a problem with RAM modules.

    Weather Application Battery Drain

    • The best solution to view weather forecasts while traveling with a mobile weather application to reduce battery drain is to use cellular location for weather app usage less frequently.

    Printer Issue

    • If a printer prints too light, a likely cause is the print drum being worn.

    Mobile Phone Charging Issue

    • A possible issue causing a mobile phone to get very hot and not retain charge is a damaged charging port.

    Laptop Upgradation

    • To upgrade a computer to increase performance for larger database, use a hybrid drive and upgrade RAM.

    Client-Side Virtualization

    • The best solution for developer to request for client-side virtualization is implementing sandbox environment for coding.

    Tablet Cursor Issue

    • The most likely cause of a drifting cursor on a tablet is that the screen needs to be recalibrated.

    Mobile Phone Icon Issue

    • The most likely cause of icons not responding on a mobile phone after a drop is a digitizer issue.

    Wireless Network Connectivity Issue

    • The issue of intermittent loss of wireless connectivity in a small office is most likely due to device interference.

    Computer Display Settings Upgrade

    • To solve an issue with a monitor not showing and extending the desktop/display settings, check the monitor's display settings and the computer's display settings and ensure they are properly set.

    Router Issue Resolution

    • An issue involving a phone not booting due to an RJ45 receptacle issue with an unmanaged switch is best solved immediately by changing ports on the switch.

    Network Protocol

    • The most likely network protocol used for a networked device to be assigned the same IP address is DHCP (Dynamic Host Configuration Protocol).
