Dell Cloud Infrastructure Design 2023 (D-CI-DS-23) recommended training questions

Hi Team. The specialist cloud infrastructure and planning certification (DES-2T13) just got updated to D-CI-DS-23. However, in the exam description, the recommended training is the same as the past certification, which is from 2018, (Cloud Infrastructure Planning and Design v2 – On Demand Course). Before I start studying, is this the right material? or there's a mistake in the exam description and there's actually a new recommended training. Thanks in advance :)
