FC0-U71 Practice Question: That their computer is slow when running multiple…

A user reports that their computer is slow when running multiple applications simultaneously. Which component upgrade would best improve performance?

⚠ Common exam trap

It's easy for candidates to confuse a slow system with a CPU bottleneck, but the question specifically describes running multiple applications simultaneously, which points to RAM as the limiting factor, not processor speed.

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

✓

RAM

When multiple applications run simultaneously, the operating system uses RAM to store active data for quick access. Insufficient RAM forces the system to rely on the hard drive as virtual memory (paging), which is dramatically slower. Upgrading RAM reduces this paging activity, improving multitasking performance.

Answer analysis

Option-by-option breakdown

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

  • ✓

    RAM

    Why this is correct

    Adding RAM increases the amount of memory available to run multiple applications simultaneously.

  • ✗

    Video card

    Why it's wrong here

    Video card upgrade only improves graphics rendering, not general multitasking.

  • ✗

    CPU

    Why it's wrong here

    CPU upgrade improves processing speed but not multitasking capacity.

  • ✗

    Hard drive

    Why it's wrong here

    Hard drive upgrade improves storage speed but not multitasking.
