Broker Architecture Pattern Quiz V2

Q1. Which component in the Broker pattern resides on the **client** side and handles marshalling of requests?



Q2. What term describes the Broker pattern’s ability to let a client invoke a service without hard-coding its network address?



Q3. A company’s microservices call each other directly over HTTP. Engineers complain about duplicated auth code, brittle endpoints, and scaling headaches. **Which architectural pattern best addresses these issues?**

Q9. Designing an API that requires dozens of tiny remote calls to finish a single business action exemplifies which anti-pattern?



Q10. Your API gateway has gradually accumulated message transformations, orchestration flows, and conditional business rules, becoming a single giant service. **Which anti-pattern does this illustrate?**
