SAP Marketing Cloud Certification

Hi,

I started SAP Marketing cloud 4 months back. Following learning path matches with the work I do - https://help.sap.com/learning-journeys/06e939ae447649f28de99b987f368496

But, the certification link ( CLS01 ) at the end of the learning path is not redirecting me to the certification page. May you please suggest certification which best suites to me.

Thank-you
