This FC0-U61 practice question tests your understanding of applications and software. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which TWO of the following are common file formats for images?
Why wrong: PDF is a document format.
PNG
PNG is a common image format.
TXT
Why wrong: TXT is a plain text file format.
MP3
Why wrong: MP3 is an audio format.
JPEG
JPEG is a widely used image format.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
PNG
PNG (Portable Network Graphics) is a common image file format that uses lossless compression, making it ideal for images requiring high detail and transparency. It supports up to 48-bit true color and an alpha channel for transparency, which distinguishes it from other formats like JPEG.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Why it's wrong here

Common exam traps
CompTIA often tests the distinction between file formats by including common non-image formats like PDF or TXT, leading candidates to confuse document or text formats with image formats.
Detailed technical explanation
PNG uses DEFLATE compression (a combination of LZ77 and Huffman coding) to reduce file size without losing data, which is critical for applications like web graphics or screenshots where pixel-perfect reproduction is required. JPEG, in contrast, uses lossy compression based on the discrete cosine transform (DCT), discarding high-frequency data to achieve smaller file sizes, making it suitable for photographs but not for images with sharp edges or text. In real-world scenarios, choosing between PNG and JPEG affects file size, quality, and support for transparency, such as when saving a logo with a transparent background for a website.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the FC0-U61 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
