Sure Pass Exam 220-1201 PDF

The correct answer is D. Data is being throttled .

Data throttling refers to the intentional slowing down of internet speeds by a mobile carrier after a user reaches a certain data usage limit or during network congestion. In this scenario, the employee can still successfully upload files, but the speed has decreased compared to before—this is a classic symptom of throttling.

Why the other options are incorrect:

A. Wireless is turned off

If wireless were turned off, the employee would not be able to upload anything at all. The question clearly states that uploads are still successful.

B. 5G is disabled

Disabling 5G could reduce speeds slightly if the device falls back to 4G/LTE, but it would not typically cause a significant or noticeable degradation unless compared under ideal conditions. It is not the most likely cause.

C. Roaming is turned on

Roaming allows connectivity outside the home network. While it may incur additional charges, it does not inherently cause significant speed reduction in most modern networks. It is less likely than throttling.

Exam Tip (Core 1 220-1201):

Slow but working connection → Think throttling or congestion

No connection → Think disabled wireless or network issues

Final Answer: D. Data is being throttled

The correct answer is D. Decreased burn-in .

According to CompTIA A+ Core 1 220-1201 objectives under Hardware and Display Technologies:

Mini-LED displays use an array of tiny LEDs as a backlight for LCD panels.

Unlike OLED displays , which are susceptible to burn-in (permanent image retention when static content is displayed for long periods), mini-LEDs reduce the risk because the pixels themselves do not emit light individually and are less prone to permanent image retention.

Why the other options are incorrect:

A. Increased contrast: OLED typically provides better contrast because it can turn off individual pixels completely.

B. No backlight: Mini-LEDs still use a backlight, whereas OLEDs do not.

C. Improved viewing angle: OLEDs generally offer wider viewing angles than mini-LED LCDs.

The correct answer is B. NVMe SSD .

According to CompTIA A+ Core 1 220-1201 objectives under Hardware and Storage:

NVMe (Non-Volatile Memory Express) SSDs provide the fastest data access and retrieval speeds compared to other storage types, especially on laptops. NVMe SSDs use the PCIe interface, which allows significantly higher throughput and lower latency than SATA-based storage.

This improves boot times, application load times, and overall system responsiveness.

Why the other options are incorrect:

A. SATA M.2: While faster than traditional 2.5” SSDs and HDDs, SATA M.2 is limited by the SATA III interface (~600 MB/s), which is slower than NVMe SSDs (~3,000–7,000 MB/s).

C. Optical disk: Optical media (CD/DVD/Blu-ray) is extremely slow and not suitable for quick access or retrieval.

D. 7,200rpm HDD: Mechanical hard drives have the slowest access times and throughput compared to SSDs.

The correct answer is B. Change the resolution .

According to the CompTIA A+ Core 1 220-1201 objectives, troubleshooting display issues involves checking the display settings, including resolution, scaling, and orientation. When a projector is only showing part of a laptop screen:

The most common cause is that the laptop’s output resolution does not match the projector ' s native resolution. If the laptop is set to a resolution larger than what the projector supports, only a portion of the screen is visible.

The technician should first adjust the laptop ' s resolution to match the projector’s native resolution before attempting other options like extending or mirroring the desktop.

Why the other options are incorrect:

A. Extend the desktop : This is only used if the user wants to have two separate screens (dual monitors), not to fix partial display issues.

C. Mirror the desktop : Mirroring duplicates the laptop display but does not solve issues caused by resolution mismatch.

D. Switch the input source : Necessary only if the projector is on the wrong input, but the problem here is a partial display, not no display.
