Focus on what universal design is and why it is important. Make sure you include examples of work you've done that ties in with the concept of universal design. This shows that not only do you know what it is, you understand how it informs the work that you do as a designer.

The goal is to showcase that you have a deep knowledge of design that goes beyond basic aesthetic principles. When answering, you have an opportunity to tie in the ethics of design and the need for diversity and inclusion in design. Answering this question correctly takes you out of the realm of being someone who just likes to design and into the realm of someone who is a deep thinker and considers all factors that should inform design deliverables.

Universal design is good design. It is creating design that is accessible to people with a wide range of abilities, disabilities, and other characteristics. It ensures that design is inclusive. A good example of universal design is any consumer-facing website. It should have the option to change the appearance or functionality of the site for those who are visually impaired.
