Response for fixed-date, fixed-scope, and fixed-budget:
1. Learn and understand why the date, scope, and budget is fixed
2. Help the stakeholders understand that there are levels of uncertainty when working on complex adaptive problems. For example, the cone of uncertainty
3. When expectations are clear and everyone is on the same page, collaboratively come up with different options. For example, funding releases or Sprints in order to manage expectations One advantage of a fixed date, scope, and budget:
The date, scope, and budget constraints are known upfront
One disadvantage of a fixed date, scope, and budget:
Flexibility and agility is reduced and the risk of building something users don't want increases
For this answer, it is explored the differences between traditional and agile product development, observe that is important to describe advantages and disadvantages for the traditional format as it also can create value, and remember, there is no silver-bullet for a product development, neither traditional or agile, the main gain is that an agile approach support rapid adaptation and better team collaboration

Scrum Guide
An Increment is a concrete stepping stone toward the Product Goal. Each Increment is additive to all prior Increments and thoroughly verified, ensuring that all Increments work together. In order to provide value, the Increment must be usable.
Multiple Increments may be created within a Sprint. The sum of the Increments is presented at the Sprint Review thus supporting empiricism. However, an Increment may be delivered to stakeholders prior to the end of the Sprint. The Sprint Review should never be considered a gate to releasing value.

Three risks with long/major release timelines compared to rapid functional releases:
1. As the release cycle becomes longer, the ability to respond to market change decreases
2. For larger releases (with many increments and features), it is more difficult to measure the impact of each increment and/or features and how they affect each other
3. As the release cycle becomes longer, transparency decreases which result in an increased risk of deviating from the product vision How Scrum manages risks:
Scrum uses empiricism to manage risk. The framework uses an iterative and incremental approach to control risk and optimize predictability. It values transparency, inspection, adaptation, self-organization, cross-functionality, and Scrum Values. Scrum prescribes time-boxed events that are used as feedback loops. For example, Sprints limit risk to a maximum of one calendar month of cost.
For this answer, it is explained the differences between short and long releases, and as an experienced product professional, you can use your own experience to exemplify it and also sustain your answer. Observe that long releases can be harmful to your product as it takes time to validate ideas and hypothesis, however, short releases might help, but you should observe if the frequency is not too high for your customers/users to follow

When working on software development, as it is complex work, the chances of having dependencies are very likely, and they can create risks, so the ordering of the Product Backlog items should consider dependencies as well

It is not required that a Product Owner Always being near the Scrum Team in case they have questions or writes and adding User Stories to the Product Backlog.
