Connectors practice questions

HDMI to DVI and DisplayPort to HDMI

Why wrong: This would connect the HDMI port to DVI (works) and DisplayPort to HDMI (works), but the question asks for a cable combination, not adapters.

Two HDMI cables, using a splitter

Why wrong: A splitter would duplicate the same signal, not extend the desktop, which is required for dual monitors.

DisplayPort to HDMI and VGA to DVI

Why wrong: VGA to DVI would require an active converter and is less reliable than digital connections.

The SSD uses a USB-A to USB-C cable, which is incompatible.

Why wrong: USB-A to USB-C cables are common and compatible if the devices support the same protocol; this scenario uses a USB-C SSD.

The laptop's USB-C port is damaged and needs replacement.

Why wrong: While possible, the SSD works on another computer, making a damaged port on the laptop less likely than a protocol mismatch.

The SSD requires a Thunderbolt 3 connection, which the laptop lacks.

Why wrong: Thunderbolt 3 is a specific protocol over USB-C, but the SSD is USB 3.2 Gen 2, not Thunderbolt.

Connect the 20-pin portion only and leave the 4-pin unconnected; use the 8-pin CPU connector as is.

Why wrong: Leaving the 4-pin unconnected may cause instability or failure to boot, and the 8-pin CPU connector may not fit a 4-pin header.

Use the 20+4 pin as a 24-pin, and connect the 8-pin CPU connector to the 4-pin header by forcing it.

Why wrong: Forcing an 8-pin connector into a 4-pin header can damage the motherboard or power supply.

Replace the power supply with one that has a dedicated 24-pin and 4-pin connector.

Why wrong: While this would work, it is unnecessary because the existing power supply can be configured correctly.

Use a Y-splitter cable on one SATA port to connect two drives.

Why wrong: Y-splitters are for power, not data; SATA data cables cannot be split to connect multiple drives.

Use eSATA to SATA adapters on the external ports.

Why wrong: eSATA is for external drives; the scenario requires internal connections, and adapters would not add ports.

Replace the motherboard with one that has six SATA ports.

Why wrong: While possible, it is not the best solution because it is more expensive and time-consuming than adding an expansion card.

The USB cable is damaged and needs replacement.

Why wrong: A damaged cable would likely cause disconnection or errors, not a consistent slow speed.

The external hard drive is not compatible with USB 3.0.

Why wrong: The drive works at high speed on the rear port, proving it is USB 3.0 compatible.

The front-panel USB port is not receiving enough power.

Why wrong: Insufficient power could cause the drive to not spin up or disconnect, but not consistently slow transfer speeds.

The monitor's resolution is set too high for the VGA cable.

Why wrong: While high resolutions can cause issues, flickering is more often due to physical connection problems than resolution settings.

The laptop's VGA port is not providing enough power.

Why wrong: VGA does not carry power; it only transmits video signals, so power is not the issue.

The VGA cable is not compatible with the laptop's graphics card.

Why wrong: VGA is a standard analog interface; incompatibility is unlikely unless the graphics card lacks VGA support, which is rare.

The laptop's Thunderbolt 4 port is disabled in BIOS.

Why wrong: While possible, it is less likely than a cable issue because the eGPU works on another laptop, suggesting the laptop's port is functional.

The eGPU requires a Thunderbolt 3 port, not Thunderbolt 4.

Why wrong: Thunderbolt 4 is backward compatible with Thunderbolt 3, so this should not be an issue.

The laptop's Thunderbolt 4 port is not providing enough power.

Why wrong: Thunderbolt 4 ports provide up to 100W, but eGPUs typically have their own power supply, so power is not the issue.

HDMI to VGA adapter

Why wrong: VGA is analog and requires an active converter; it will not work with a digital DisplayPort monitor directly.

DisplayPort to USB-C adapter

Why wrong: This adapter would connect a DisplayPort source to a USB-C monitor, but the PC has HDMI, not DisplayPort.

DVI to HDMI adapter

Why wrong: This adapter would connect a DVI source to an HDMI monitor, but the PC has HDMI output, not DVI.

USB-C to USB-C cable

Why wrong: The projector has HDMI input, not USB-C, so a USB-C to USB-C cable would not connect to the projector.

HDMI to HDMI cable

Why wrong: The laptop has USB-C, not HDMI, so an HDMI cable cannot connect directly.

DisplayPort to HDMI cable

Why wrong: The laptop has USB-C, not DisplayPort, so this cable would not connect to the laptop.

Use a Molex to 8-pin adapter on one of the connectors.

Why wrong: Molex to PCIe adapters exist but are not recommended for high-power cards due to potential fire risk; a 6+2 cable is safer.

Plug the 6-pin connector into the 8-pin slot; it will work with reduced power.

Why wrong: Forcing a 6-pin into an 8-pin slot may damage the connector or cause insufficient power delivery.

Replace the power supply with one that has two 8-pin connectors.

Why wrong: While this would work, it is not the best solution because a simple cable change is more cost-effective and less time-consuming.

HDMI to DVI adapter

Why wrong: DVI is digital and not compatible with VGA without conversion.

USB-C to VGA adapter

Why wrong: The laptop has HDMI output, not USB-C, so this adapter won't connect.

DisplayPort to VGA adapter

Why wrong: The laptop outputs HDMI, not DisplayPort, so this adapter is not suitable.

The SSD is formatted with FAT32

Why wrong: File system does not affect USB speed; it only affects file size limits.

The motherboard BIOS needs updating

Why wrong: BIOS updates rarely affect USB speed; the issue is more likely hardware-related.

The SSD is connected via a USB 2.0 hub

Why wrong: The scenario states it's connected to a front panel port, not a hub.

The HDMI cable is faulty

Why wrong: While possible, the most direct issue is the adapter type, not the cable itself.

The monitor is set to the wrong input source

Why wrong: Input source could be wrong, but the adapter incompatibility is the primary problem.

The graphics driver is outdated

Why wrong: Driver issues could cause no signal, but the adapter mismatch is a more immediate hardware problem.

USB to serial adapter

Why wrong: Serial ports are different from parallel ports; a serial adapter will not work with a parallel printer.

USB to PS/2 adapter

Why wrong: PS/2 is for keyboards and mice, not printers.

USB to VGA adapter

Why wrong: VGA is for video, not printer communication.

Connect only the 6-pin portion

Why wrong: The card requires 8 pins; using only 6 may not provide enough power and could cause instability.

Use a Molex to 8-pin adapter

Why wrong: While possible, this is less efficient and may not be necessary if the PSU has a 6+2 pin connector.

Connect a SATA power cable to the card

Why wrong: SATA power cables are not compatible with graphics card power inputs and could cause damage.

The drive will not be recognized

Why wrong: SATA III drives are backward compatible with SATA II and will be recognized.

The drive will operate at SATA III speeds

Why wrong: The backplane limits the speed to SATA II (3 Gbps), so the drive cannot run at SATA III speeds.

The drive will be damaged

Why wrong: SATA interfaces are designed for backward compatibility, so no damage will occur.

Rollover cable

Why wrong: Rollover cables are used for console connections to network devices, not for standard Ethernet links.

Crossover cable

Why wrong: Crossover cables are for connecting two similar devices (e.g., PC to PC), not a modem to a router.

Fiber optic cable

Why wrong: Fiber optic is not used with RJ45 ports; it requires specialized connectors and transceivers.

Connect the 4+4 pin as a 4-pin connector only

Why wrong: The motherboard requires an 8-pin EPS connector; using only 4 pins may not provide enough power and could cause instability.

Use a 6+2 pin PCIe power connector

Why wrong: PCIe connectors are for graphics cards, not CPU power, and are keyed differently, so they won't fit.

Leave the CPU power unconnected

Why wrong: Without CPU power, the motherboard will not boot or may fail to initialize.

The graphics card driver is outdated

Why wrong: Driver issues usually cause persistent problems, not intermittent flickering.

The monitor's refresh rate is set too high

Why wrong: High refresh rates can cause issues, but flickering is more often due to cable problems.

The DVI port is incompatible with the cable

Why wrong: DVI-I and DVI-D are generally compatible; incompatibility is rare and would cause no signal, not flickering.

USB-A to USB-B cable

Why wrong: USB-B is typically used for printers and larger devices, not external hard drives, and would not match the drive's USB-C connector.

USB-A to USB-C adapter

Why wrong: An adapter would allow connection to a USB-A port, but it may reduce speed and is not the fastest option.

Micro-USB to USB-C cable

Why wrong: Micro-USB is an older standard and not compatible with the external hard drive's USB-C connector.
