220-1201 Practice Question: A user wants to mirror their Android smartphone's…
A user wants to mirror their Android smartphone's screen to a smart TV that does not support Miracast. The TV has HDMI and USB ports. Which device should the technician recommend?
⚠ Common exam trap
The 220-1201 exam often tests the misconception that any USB-C to HDMI cable will work for screen mirroring, but many Android phones lack DisplayPort Alt Mode support, making Option A a common distractor.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
A Chromecast device
A Chromecast device connects to the TV via HDMI and uses Wi-Fi Direct (not Miracast) to receive a screen mirror from an Android smartphone. Since the TV lacks Miracast support but has an HDMI port, Chromecast provides the necessary hardware and protocol (Google Cast) to enable wireless display mirroring.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
A USB-C to HDMI cable
Why it's wrong here
A USB-C to HDMI cable provides a wired connection for video output, but many Android smartphones do not support DisplayPort Alternate Mode (Alt Mode) over their USB-C port, which is required for direct video transmission. Even if supported, this is a direct, physical connection and not a wireless screen mirroring solution that utilizes Wi-Fi, which is typically implied when a user wants to 'mirror' their screen in a modern context.
- ✗
A Bluetooth transmitter
Why it's wrong here
A Bluetooth transmitter is designed for short-range, low-bandwidth data transfer, primarily for audio streaming using profiles like A2DP or connecting peripherals. Bluetooth technology lacks the necessary bandwidth and throughput to transmit high-resolution, real-time video streams required for effective screen mirroring. Therefore, it cannot be used to mirror a smartphone's display to a larger screen.
- ✓
A Chromecast device
Why this is correct
A Chromecast device is specifically designed for wireless screen mirroring and media streaming. It connects to an HDMI port on a display and utilizes Wi-Fi to receive content from an Android smartphone via the Google Cast protocol. This allows users to wirelessly cast or mirror their entire smartphone screen or specific application content to a television or monitor, providing a convenient and widely supported solution.
- ✗
An NFC tag
Why it's wrong here
An NFC tag uses Near Field Communication, a very short-range wireless technology primarily for initiating actions, pairing devices, or facilitating contactless payments through extremely low-bandwidth data exchange. NFC is not capable of transmitting continuous, high-bandwidth video streams required for screen mirroring. Its purpose is to trigger events or exchange small amounts of data, not to act as a display output mechanism.
