Question 1

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?

AImplement the Async scope fetch the data from the backend application and to insert records in the Audit database

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

CImplement 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

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

Answer : D

Question 2

49 of A popular retailer is designing a public API for its numerous business partners. Each business partner will invoke the API at the URL 58. https://api.acme.com/partnefs/vl. The API implementation is estimated to require deployment to 5 CloudHub workers.

The retailer has obtained a public X.509 certificate for the name apl.acme.com, signed by a reputable CA, to be used as the server certificate.

Where and how should the X.509 certificate and Mule applications be used to configure load balancing among the 5 CloudHub workers, and what DNS entries should be configured in order for the retailer to support its numerous business partners?

AAdd the X.509 certificate to the Mule application's deployable archive, then configure a CloudHub Dedicated Load Balancer (DLB) for each of the Mule application's CloudHub workers
Create a CNAME for api.acme.com pointing to the DLB's A record

BAdd the X.509 certificate to the CloudHub Shared Load Balancer (SLB), not to the Mule application
Create a CNAME for api.acme.com pointing to the SLB's A record

CAdd the X.509 certificate to a CloudHub Dedicated Load Balancer (DLB), not to the Mule application
Create a CNAME for api.acme.com pointing to the DLB's A record

DAdd the x.509 certificate to the Mule application's deployable archive, then configure the CloudHub Shared Load Balancer (SLB)
for each of the Mule application's CloudHub workers
Create a CNAME for api.acme.com pointing to the SLB's A record

Answer : C

* An X.509 certificate is a vital safeguard against malicious network impersonators. Without x.509 server authentication, man-in-the-middle attacks can be initiated by malicious access points, compromised routers, etc.

* X.509 is most used for SSL/TLS connections to ensure that the client (e.g., a web browser) is not fooled by a malicious impersonator pretending to be a known, trustworthy website.

* Coming to the question , we can not use SLB here as SLB does not allow to define vanity domain names. * Hence we need to use DLB and add certificate in there

---------------------------------------------------------------------------------------------------------------------

Hence correct answer is Add the X 509 certificate to the cloudhub Dedicated Load Balancer (DLB), not the Mule application. Create the CNAME for api.acme.com pointing to the DLB's record

Question 3

A high-volume eCommerce retailer receives thousands of orders per hour and requires notification of its order management, warehouse, and billing system for subsequent processing within 15 minutes of order submission through its website.

Which integration technology, when used for its typical and intended purpose, meets the retailer's requirements for this use case?

AManaged File Transfer (MFT)

BPublish/Subscriber Messaging Bus (Pub/Sub)

CEnterprise Data Warehouse (EDW)

DExtract Transform Load (ETL)

Answer : D

Question 4

Refer to the exhibit.

One of the backend systems invoked by an API implementation enforces rate limits on the number of requests a particular client can make. Both the backend system and the API implementation are deployed to several non-production environments in addition to production.

Rate limiting of the backend system applies to all non-production environments. The production environment, however, does NOT have any rate limiting.

What is the most effective approach to conduct performance tests of the API implementation in a staging (non-production) environment?

ACreate a mocking service that replicates the backend system's production performance characteristics. Then configure the API implementation to use the mocking service and conduct the performance tests

BUse MUnit to simulate standard responses from the backend system then conduct performance tests to identify other bottlenecks in the system

CInclude logic within the API implementation that bypasses invocations of the backend system in a performance test situation. Instead invoking local stubs that replicate typical backend system responses then conduct performance tests using this API Implementation

DConduct scaled-down performance tests in the staging environment against the rate limited backend system then upscale performance results to full production scale

Answer : A

Correct answer is Create a mocking service that replicates the backend system's production performance characteristics. Then configure the API implementation to use the mocking service and conduct the performance tests

* MUnit is for only Unit and integration testing for APIs and Mule apps. Not for performance Testing, even if it has the ability to Mock the backend.

* Bypassing the backend invocation defeats the whole purpose of performance testing. Hence it is not a valid answer.

* Scaled down performance tests cant be relied upon as performance of API's is not linear against load.

Question 5

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?

AA 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.

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

CSeparate 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

DA 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.

Answer : C

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

Question 6

As a part of design , Mule application is required call the Google Maps API to perform a distance computation. The application is deployed to cloudhub.

At the minimum what should be configured in the TLS context of the HTTP request configuration to meet these requirements?

AThe configuration is built-in and nothing extra is required for the TLS context

BRequest a private key from Google and create a PKCS12 file with it and add it in keyStore as a part of TLS context

CDownload the Google public certificate from a browser, generate JKS file from it and add it in key store as a part of TLS context

DDownload the Google public certificate from a browser, generate a JKS file from it and add it in Truststore as part of the TLS context

Answer : A
