Salesforce Certified Platform Integration Architect (Plat-Arch-204) Exam Practice Test Instant Access

Question 1

An enterprise architect has requested the Salesforce Integration architect to review the following (see diagram & description) and provide recommendations after carefully considering all constraints of the enterprise systems and Salesforce platform limits.

* About 3,000 phone sales agents use a Salesforce Lightning UI concurrently to check eligibility of a customer for a qualifying offer.

* There are multiple eligibility systems that provides this service and are hosted externally. However, their current response times could take up to 90 seconds to process and return (there are discussions to reduce the response times in future, but no commitments are made).

* These eligibility systems can be accessed through APIs orchestrated via ESB (MuleSoft).

* All requests from Salesforce will have to traverse through customer's API Gateway layer and the API Gateway imposes a constraint of timing out requests after 9 seconds.

Which three recommendations should be made?

Choose 3 answers

AESB (Mule) with cache/state management to return a requestID (or) response if available from external system.

BRecommend synchronous Apex call-outs from Lightning UI to External Systems via Mule and implement polling on API gateway timeout.

CUse Continuation callouts to make the eligibility check request from Salesforce from Lightning UI at page load.

DWhen responses are received by Mule, create a Platform Event in Salesforce via Remote-Call-In and use the empAPI in the lightning UI to serve 3,000 concurrent users.

EImplement a 'Check Update' button that passes a requestID received from ESB (user action needed).

Answer : A, C, E

Question 2

An organization needs to integrate Salesforce with an external system and is considering authentication options. The organization already has implemented SAML, using a third-party Identity Provider for integrations between other systems.

Which use case can leverage the existing SAML integration to connect Salesforce with other internal systems?

AMake formula fields with HYPERLINK() to external web servers more secure.

BMake Apex SOAP outbound integrations to external web services more secure.

CA Make Apex REST outbound integrations to external web services more secure.

DMake an API inbound integration from an external Java client more secure.

Answer : A

Question 3

Northern Trail Outfitters (NTO) has recently changed their Corporate Security Guidelines. The guidelines require that all cloud applications pass through a secure firewall before accessing on-premise resources. NTO is evaluating middleware solutions to integrate cloud applications with on-premise resources and services.

What are two considerations an Integration Architect should evaluate before choosing a middleware solution?

Choose 2 answers

AThe middleware solution is capable of establishing a secure API gateway between cloud applications and on-premise resources.

BAn API gateway component is deployable behind a Demilitarized Zone (DMZ) or perimeter network.

CThe middleware solution enforces the OAuth security protocol.

DThe middleware solution is able to interface directly with databases via an ODBC connection string.

Answer : A, B

Question 4

Northern Trail Outfitters (NTO) has an integration set up between a Salesforce org and a quoting system. NTO would like to show a notification to all sales representatives that use Salesforce anytime the quoting system will be taken down for maintenance.

Which Salesforce API should an Integration Architect use to fulfill this requirement?

AConnect REST API

BTooling API

CREST API

DStreaming API

Answer : D

Question 5

When user clicks Check Preferences as part of a Lightning flow in Salesforce, preferences from an externally hosted RESTful service are to be checked in real-time. The RESTful service has OpenAPI 2.0 JSON definitions, responding in data types of Boolean and string values.

Which integration pattern and mechanism should be selected to meet the conditions?

AFire and Forget: Process-driven platform events publishes events on Salesforce Event Bus.

BRemote Call-In: Salesforce REST API with REST Composite Resources.

CRequest-Reply: Enhanced External Services invokes a REST API.

DData Virtualization: Salesforce Connect map data external REST data in external objects.

Answer : C

Question 6

Customer is evaluating Platform Events solution and would like help in comparing/contrasting it with Outbound Message for a real-time / near-real time needs. They expect 3,000 consumers of messages from Salesforce.

Which three considerations should be evaluated and highlighted when deciding between the solutions?

Choose 3 answers

ABoth Platform Events and Outbound Message offer declarative means for asynchronous near-real time needs. They aren't best suited for real-
time integrations.

BIn both Platform Events and Outbound Messages, the event messages are retried by and delivered in sequence, and only once. Salesforce ensures there is no duplicate message delivery.

CMessage sequence is possible in Outbound Message but not guaranteed with Platform Events. Both offer very high reliability. Fault handling
and recovery are fully handled by Salesforce.

DNumber of concurrent subscribers to Platform Events is capped at 2,000. An Outbound Message configuration can pass only 100 notifications in a single messages to a SOAP end point.

EBoth Platform Events and Outbound Message are highly scalable. However, unlike Outbound Message, only Platform Events have Event Delivery and Event Publishing limits to be considered.

An Integration Developer is developing an HR synchronization app for a client. The app synchronizes Salesforce record data changes with an HR system that's external to Salesforce.

What should the integration architect recommend to ensure notifications are stored for up to three days if data replication fails?

AChange Data Capture

BGeneric Events

CPlatform Events

DCallouts
