I am on a deffered judgement for a domestic violence case which will be dismissed in 06/12. Will I need expungement as well?

Asked in Newark, CA - about 1 year

I am having extreme difficulty getting a good job as this case shows up in the bg check. I am a engineer with no other arrests/ record other than this one - The case shows as a misdeaminor on the BG check , it happened in 10/10 and the court gave me 1 year dv classes which are completed successfully, the judge said that the the case will be automatically dismissed in 06/12. Will I need to get expungement done to get it off my record after it is dismissed or does 'dismissed' mean that I can answer 'no' to the have to ever been convicted question? Thank you for your help.
