dnssec issue with cnmae

Hi Team,

We have recently enbaled dnssec for test.com on mark monitor after that  cnmae url new.test.com failing resolution.

new.test.com was create cnmae with aws hosted app elb url example like myurl.ucs-1@elb.amazon.com.

Question is any action require on cname url new.test.com or amazon elb domain to proparly dnssec work when we did on test.com.

Thx
