According to MuleSoft's recommended API-led connectivity approach, what is the best layer for this new API?
- A. Process layer
- B. System layer
- C. Security layer
- D. Experience layer
Answer : A

- B. In API Manager, apply a Client ID Enforcement policy for the API instance
- C. In Anypoint Design Center, code a custom policy for Client ID Enforcement and then publish the custom policy to the API portal in Anypoint Exchange
- D. In API Designer, add Client ID Enforcement policy requirements to the API specification
Answer : B
Question 5
Refer to the exhibits. In the execution of the Scatter-Gather, the "sleep 1 sec" Flow Reference takes about 1 second to complete, and the "sleep 5 secs" Flow Reference takes about 5 seconds to complete.

Answer : C
Question 6
Refer to the exhibits. A database Address table contains a ZIPCODE column and an increasing ID column. The Address table currently contains four (4) records. The On Table Row Database listener is configured with its watermark set to the Address table's ZIPCODE column and then the Mule application is run in Anypoint Studio for the first time, and the On Table Row Database listener polls the Address table.
A new row is added to the database with ID=5 and ZIPCODE=90006, and then the On Table Row Database listener polls the database again.

A.
-
B.
-
C.
-
D.
Answer : C
