FC0-U71 Practice Question: A user wants to open a PDF file but receives an…

A user wants to open a PDF file but receives an error that no application is associated. Which action should the user take?

⚠ Common exam trap

Many exam-takers confuse a missing application association with a system-level error, leading them to choose a generic troubleshooting step like restarting or updating drivers instead of recognizing the need to install the appropriate software.

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

✓

Install a PDF reader

The error 'no application is associated' means the operating system lacks a default program capable of handling the PDF file format. Installing a PDF reader, such as Adobe Acrobat Reader or a web browser with built-in PDF support, registers the necessary file association and allows the file to open correctly.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • ✗

    Update device drivers

    Why it's wrong here

    Device drivers do not affect file association for PDFs.

  • ✓

    Install a PDF reader

    Why this is correct

    A PDF reader is required to open PDF files.

  • ✗

    Rename the file to .docx

    Why it's wrong here

    Renaming the file does not change its internal format; it will still be a PDF.

  • ✗

    Restart the computer

    Why it's wrong here

    Restarting does not install the needed application.
