A. Implement HTTP caching policy for all GET endpoints for the master lookup API and implement locking to synchronize access to object store

Comprehensive Detailed Step by Step ExplanationTo resolve the performance issue observed during the performance testing of the Master lookup API, the best approach involves caching and synchronization:

• HTTP Caching Policy:
• Object Store Locking:

By implementing these two strategies, the response time of the Master lookup API will be significantly improved, and the performance issue will be resolved.

To minimize the risk of exposing sensitive data such as credit card information while still allowing it to be converted back to its original value when necessary, tokenization is the most effective approach. Tokenization replaces sensitive data with a non-sensitive equivalent, called a token, which has no exploitable value. This method ensures that the original sensitive data is stored securely and only accessible through a secure tokenization system.

In this scenario, applying a tokenization policy at the API Gateway ensures that sensitive information is replaced with tokens before the data leaves the trusted boundary. This minimizes the risk of matching sensitive data to the original. When the original data is needed, the tokenization system can detokenize the token back to its original value securely.

Explanation

Correct answer is For Each scope in the parent flow On Error Continue error handler in the child flow. You can extract below set of requirements from the question a) Records should be sent to downstream system in the same order that it was received in the array b) Any validation or communication failures should not prevent further processing of the remaining records First requirement can be met using For Each scope in the parent flow and second requirement can be met using On Error Continue scope in child flow so that error will be suppressed.
