  What is a risk to data privacy during the storage and transmission of data?

  A. The risk of exposure is increased when data is shared between applications.
  B. The transfer of unencrypted data between storage devices increases the risk of exposure.
  C. Data breaches cause ongoing exposure of personal information.

• Question 83:

  An application is made up of multiple microservices, each communicating via APIs. One service is beginning to be a bottleneck for the application because it can take a lot of time to complete requests. An engineer tried adding additional instances of this service behind the load balancer, but it did not have any effect. Which application design change must be implemented m this scenario?

  A. Move from synchronous to asynchronous interactions with the service and implement a message queue.
  B. Deploy an API gateway to centralize all inbound communication requests and offload authentication
  C. Vendor all dependencies into the service that is causing delays to remove external dependency checks.
  D. Leverage serverless architecture instead of containers to gain the advantage of event driven APIs.
  A. Move from synchronous to asynchronous interactions with the service and implement a message queue.
