How would you handle confidential information?

Hi all, i had this question which completely left me blank and i was waffling on.
I applied for the receptionist role at a higher education institution and it was in the health and well-being department so they provided support for those needing counseling, medical help or those with disabilities.

I was asked working as a receptionist required working autonomously and how would i handle confidential information. I replied with i would ensure that i read up on the companies policies and procedures and research what i should know and make sure i wouldn’t divulge confidential information.

Looking back i think my response should have been

‘Working on the hotlines for the clearing period where a large volume of calls were made by potential students wanting admission to the university i would ensure that files that were not important were shredded and destroyed and important files were stored away, also confidential information wouldn’t be revealed to those who weren’t the individual looking for a place at the university and was polite and clear about abiding by the confidential act as i know the university reputation is important, also if i was away from the computer i would make it was locked so no one other than myself would access any personal information’

Could you help by saying would this reply have been better and what other answer would you have given using the example of the hotlines.

Thankyou
