Câu 19: Certified Mulesoft Platform Integration Architect

Refer to the exhibit. A manufacturing company is developing a new set of APIs for its retail business. One of the APIs is a Master Look Up API, which is a System API. The API uses a persistent object-store. This API will be used by almost all other APIs to provide master lookup data. The Master Look Up API is deployed on two CloudHub workers of 0.1 vCore each because there is a lot of master data to be cached. Most of the master lookup data is stored as a key-value pair. The cache gets refreshed if the key is not found in the cache. During performance testing, it was determined that the Master Look Up API has a high response time due to the latency of database queries executed to fetch the master lookup data. What two methods can be used to resolve these performance issues? (Choose two.)
