What advice would you give the development team in order to avoid the issue?

Your organization recently bought 1.000 licenses for Cloud Identity Premium. The company’s development team created an application in the enterprise service bus (ESB) that will read user data in the human resources information system (HRIS) and create accounts via the Google Directory REST API.

While doing the original test before production use, the team observes a 503 error coming from Google API response after a few users are created The team believes the ESB is not the cause, because it can perform 100 requests per second without any problems.

What advice would you give the development team in order to avoid the issue?
A . Use the domain-wide delegation API to avoid the limitation per account.
B . Use an exponential back-off algorithm to retry failed requests.
C . Switch from REST API to gRPC protocol for performance improvement
