Hello @RAQUEEBUL ISLAM SHAIK
welcome to this moderated Azure community forum.
From the top of my mind, these fundamentals virtual training days are normally pre-recorded with live Q&A next to it. You will be able to attend at another time but then the live Q&A is closed.
Please check the portal (a link should be available) for the definitive dates. Probably you can get a (outlook) calendar invitation too.
If the response helped, do "Accept Answer". If it doesn't work, please let us know the progress. All community members with similar issues will benefit by doing so. Your contribution is highly appreciated.
