A technician needs to run a diagnostic DVD on a laptop running Windows 8.1. After setting the boot order in the UEFI BIOS to the internal DVD-RW drive, the laptop still boots into Windows. Which of the following settings needs to be adjusted in order for the laptop to boot from the DVD-RW drive?
The setting that needs to be adjusted is Secure Boot. Secure Boot is a feature in UEFI BIOS that ensures only trusted software can be loaded during the boot process. Since the diagnostic DVD is not signed in a way that Secure Boot recognizes, it prevents the laptop from booting from the DVD-RW drive. Disabling Secure Boot will allow the laptop to boot from the DVD-RW drive, as it will no longer restrict the boot process to trusted software only.
Which of the following types of cables are MOST likely to be used to connect to an external hard drive? (Select TWO).
The types of cables most likely to be used to connect to an external hard drive are eSATA and USB 3.0. eSATA (external SATA) is specifically designed for external hard drives, providing high-speed data transfer. USB 3.0 is also a common standard for external hard drive connections, known for its high transfer rates and widespread compatibility. Molex is typically used for internal power connections, SPDIF is for audio, HDMI is for video, and CAT6e is for networking, none of which are suited for external hard drive connections.
Which of the following is required during the installation of a digitizer?
During the installation of a digitizer, it must be calibrated to ensure accurate functionality. Calibration is essential for the device to correctly interpret and process the inputs it receives. This ensures precise conversion from analog to digital format.
A technician is troubleshooting an expansion card in a computer that allows the computer to receive faxes over a VoIP line. The line connected to the expansion card is MOST likely which of the following cable types?
The cable type most likely connected to an expansion card that allows a computer to receive faxes over a VoIP line is CAT3. This type of cable is traditionally used for telephony and would be compatible with standard telephone systems, which aligns with the need to receive faxes. CAT6, although more advanced, is typically used for higher-speed networking and not specifically suited for telephonic connections required for fax over VoIP.
Which of the following cable connection types is an example of a mini DIN?
The PS/2 port is a 6-pin mini-DIN connector used for connecting keyboards and mice to a PC compatible computer system. Its name comes from the IBM Personal System/2 series of personal computers, with which it was introduced in 1987. BNC, RCA, and DB9 are not mini DIN connectors.
