Helping the team identify the root cause of an issue (to avoid X/Y solutions), and then allowing them to brainstorm measurable solutions that work within the team's unique context is an essential Scrum Master facilitation role. Validated learning and continuous process improvement led by the team should be the real goals here.
For your framework implementation to be Scrum, you must hold a Daily Scrum. If you don't hold all the required events, then the result is not Scrum.
On the other hand, the Scrum framework doesn't prevent teams from holding additional events or implementing their own processes within the framework. So, if a team finds that it needs more than one full-team collaboration meeting a day, there's nothing that would prevent them from doing that.
On the third (!) hand, adding additional process overhead may or may not add value, and may or may not solve whatever underlying issue has prompted the team to try this approach. In the abstract, it's difficult to say whether this would be useful or not, but it's certainly within the team's control to self-organize and manage their own internal processes if they want to try. I'd simply suggest that they take a test-first approach to define how they will measure the success or failure of the process.
The Test Perspective
It's almost impossible to guess what the test designers think is the right answer, or how they've chosen to norm it. So, there can't be a canonical answer to a "what's the correct test answer" type of question.
With that said, the only two options presented that are congruent with allowing the team to self-organize and collaborate without a command-and-control approach using authority the Scrum Master doesn't have are:
- Learn why the Development Team wants this and work with them to improve the outcome of the daily Scrum
- Acknowledge and support self-organizing team’s decision
Whether or not the answers are what the test designers are looking for, they are the two best answers in the list. They still fall short, though, because they lack the full context and the right flavor. Repacking this as "What's the best way to support and facilitate the team?" is a better approach that will encourage the Scrum Master to coach the team on root cause analysis and help them explore actionable and testable approaches to validated learning and continuous improvement.
