Question 21

A leading bank implementing new mule API.
The purpose of API to fetch the customer account balances from the backend application and display them on the online platform the online banking platform. The online banking platform will send an array of accounts to Mule API get the account balances.
As a part of the processing the Mule API needs to insert the data into the database for auditing purposes and this process should not have any performance related implications on the account balance retrieval flow How should this requirement be implemented to achieve better throughput?

A.Implement a for each scope to fetch the data from the back-end application and to insert records into the Audit database

B.Implement a try-catch scope to fetch the data from the back-end application and use the Async scope to insert records into the Audit database

C.Implement parallel for each scope to fetch the data from the backend application and use Async scope to insert the records into the Audit database

D.Implement the Async scope fetch the data from the backend application and to insert records in the Audit database

Question 22

A company is designing a mule application to consume batch data from a partner's ftps server The data files have been compressed and then digitally signed using PGP.
What inputs are required for the application to securely consumed these files?

A.ATLS context first store containing a public certificate for partner ftps server and the PGP public key of the partner TLS contact Key Store containing the FTP credentials

B.ATLS context Key Store requiring the private key and certificate for the company PGP public key of partner PGP private key for the company

C.The PGP public key of the partner
The PGP private key for the company The FTP username and password

D.TLS context trust or containing a public certificate for the ftps server The FTP username and password The PGP public key of the partner

Question 23

An organization has just developed a Mule application that implements a REST API. The mule application will be deployed to a cluster of customer hosted Mule runtimes.
What additional infrastructure component must the customer provide in order to distribute inbound API requests across the Mule runtimes of the cluster?

A.A message broker

B.An HTTP Load Balancer

C.A database

D.An Object Store

Question 24

An organization needs to enable access to their customer data from both a mobile app and a web application, which each need access to common fields as well as certain unique fields. The data is available partially in a database and partially in a 3rd-party CRM system. What APIs should be created to best fit these design requirements?

A.A Process API that contains the data required by both the web and mobile apps, allowing these applications to invoke it directly and access the data they need thereby providing the flexibility to add more fields in the future without needing API changes.

B.One set of APIs (Experience API, Process API, and System API) for the web app, and another set for the mobile app.

C.Separate Experience APIs for the mobile and web app, but a common Process API that invokes separate System APIs created for the database and CRM system

D.A common Experience API used by both the web and mobile apps, but separate Process APIs for the web and mobile apps that interact with the database and the CRM System.

Correct Answer: C

Explanation
Lets analyze the situation in regards to the different options available Option : A common Experience API but separate Process APIs Analysis : This solution will not work because having common experience layer will not help the purpose as mobile and web applications will have different set of requirements which cannot be fulfilled by single experience layer API Option : Common Process API Analysis : This solution will not work because creating a common process API will impose limitations in terms of flexibility to customize API;s as per the requirements of different applications. It is not a recommended approach.
Option : Separate set of API's for both the applications Analysis : This goes against the principle of Anypoint API-led connectivity approach which promotes creating reusable assets. This solution may work but this is not efficient solution and creates duplicity of code.
Hence the correct answer is: Separate Experience APIs for the mobile and web app, but a common Process API that invokes separate System APIs created for the database and CRM system A screenshot of a computer Description automatically generated with low confidence

Question 25

An application deployed to a runtime fabric environment with two cluster replicas is designed to periodically trigger of flow for processing a high-volume set of records from the source system and synchronize with the SaaS system using the Batch job scope After processing 1000 records in a periodic synchronization of 1 lakh records, the replicas in which batch job instance was started went down due to unexpected failure in the runtime fabric environment What is the consequence of losing the replicas that run the Batch job instance?

A.A new replacement replica will be available and will be process all 1,00,000 records from scratch leading to duplicate record processing

B.A new placement replica will be available and will take or processing the remaining 99,000 records

C.The remaining 99000 records will be lost and left and processed

D.The second replicas will take over processing the remaining
99000 records
