Why might a Google Cloud customer use resources in several zones within a region? -For getting discounts on other zones -For expanding services to customers in new areas -For better performance -For improved fault tolerance

For improved fault tolerance

How does the resource hierarchy control how IAM policies are inherited? -IAM policies that are implemented higher in the resource hierarchy deny access that is granted by lower-level policies. -IAM policies that are implemented by lower-level policies can override the policies defined at a higher level. -IAM policies are only implemented at the project level; they cannot be amended by lower levels of the resource hierarchy.

IAM policies that are implemented by lower-level policies can override the policies defined at a higher level.
