Videos theory and content

Hello,
I have 2 issues with the content for the SAA course. First, I think it really lacks demos or labs. Not sure why ? Is it because some topics are less important than others ?
As a result, I tried to practice In AWS playground, but for database for example, we are not authorized to create Aurora, RDS or any other type of DB neither. What can we do ?

On top of that, I noticed some important topics are not covered in the course and then asked in the quizz. Is it expected? Here is an example :

A startup is planning to implement a messaging system using Amazon MQ for their rapidly growing user base. They need a solution that is both scalable and cost-effective. What should the Solutions Architect recommend to ensure that the use of Amazon MQ is cost-optimized?

Choose Amazon MQ with reserved broker instances for predictable workloads, offering cost savings over on-demand pricing

The course does not mention reserved broker instances, could you please advise ?

Thanks

There are labs for the course, but they start later in the course, in the latter part of the Networking module of the course. so it’s about 35 or more lessons in.

Also, the playground does allow creating databases, although you need to set the appropriate parameters for disk size and similar things. Read the playground guide carefully; it lists what these are.

I know there are labs and demos, I am nearly at 50% of overall progress but I think there are really too few.
Also, why the quizz ask question about topics not covered in the video course ?
