問題 #102
A new Salesforce program has the following high-level abstract requirement: Business processes executed on Salesforce require data updates between their internal systems and Salesforce. Which relevant detail should an integration architect seek to specifically solve for integration architecture needs of the program?
答案：A
解題說明：
In the discovery and translation phase of a Salesforce project, an Integration Architect must move beyond high-level business goals to define the technical "DNA" of the data exchange. While organizational readiness and user experience are vital to project success, they do not dictate the architectural patterns required to move data between systems.
The most critical details for designing an integration architecture are the Timing and Volume requirements. Identifying whether a business process is Synchronous or Asynchronous is the primary decision point. For example, if a Salesforce user requires an immediate validation from an external system before they can save a record, a synchronous "Request-Reply" pattern using an Apex Callout is required. If the data update can happen in the background without blocking the user, an asynchronous "Fire-and-Forget" pattern is preferred to improve system performance and user experience.
Furthermore, understanding the Update Frequency (e.g., real-time, hourly, or nightly) and the Data Volume (e.g., 100 records vs. 1 million records) allows the architect to select the appropriate Salesforce API. High-volume, low-frequency updates are best handled by the Bulk API to minimize API limit consumption, while low-volume, high-frequency updates are better suited for the REST API or Streaming API. By specifically seeking out these timing and frequency aspects, the architect ensures that the chosen solution is scalable, stays within platform governor limits, and meets the business's Service Level Agreements (SLAs). Without these details, the architect risks designing a solution that is either too slow for the business needs or too taxing on system resources.
問題 #103
A company needs to send data from Salesforce to a homegrown system behind a corporate firewall. The data is pushed one way, doesn't need to be real-time, and averages 2 million records per day. What should an integration architect consider?
答案：B
解題說明：
With a volume of 2 million records per day, this integration exceeds the practical limits of standard near-real-time patterns like Outbound Messaging or synchronous Apex Callouts. Sending 2 million individual REST requests would likely exhaust the daily API limit and could cause significant performance degradation in Salesforce due to transaction overhead.
An Integration Architect must recommend an Asynchronous Batch Data Synchronization pattern, typically facilitated by a third-party ETL/Middleware tool (e.g., MuleSoft, Informatica, or Boomi). Staging the records off-platform is essential for several reasons:
Throttling: The homegrown system behind a firewall may not be able to handle a massive, sudden burst of 2 million records. A middleware tool can ingest the data from Salesforce and "drip-feed" it into the target system at an acceptable rate.
Error Handling and Retries: Middleware provides sophisticated persistence and "Dead Letter Queues" to ensure that if the homegrown system goes offline, no data is lost.
API Efficiency: The middleware can use the Salesforce Bulk API 2.0 to extract the data in large chunks, which is significantly more efficient than individual REST calls and consumes far fewer API limits.
Option A is a valid concern but is a symptom of the wrong choice of tool (REST). Option B describes an inbound integration to Salesforce, whereas the requirement is outbound. By utilizing a third-party tool to stage and manage the 2 million record flow, the architect ensures that the integration is scalable, respects the corporate firewall constraints (via a secure agent or VPN), and maintains the performance of the Salesforce production environment.
問題 #104
Which Web Services Description Language (WSDL) should an architect consider when creating an integration that might be used for more than one Salesforce org and different metadata?
答案：C
解題說明：
In the world of Salesforce SOAP APIs, the choice of WSDL depends on the nature of the application being built. When an architect needs to build an integration that is org-agnostic-meaning it can work across multiple different Salesforce organizations with varying custom objects and fields-the Partner WSDL is the correct choice.
The Partner WSDL is loosely-typed. It does not contain information about an org's specific custom metadata; instead, it uses a generic sObject structure. This allows a single client application (like a third-party integration tool or a mobile app) to connect to any Salesforce org and dynamically discover its schema at runtime. Because it is not tied to a specific org's metadata, it does not need to be regenerated every time a custom field is added to one of the target orgs.
In contrast, Option A (Enterprise WSDL) is strongly-typed. It is generated specifically for one org and contains hard-coded references to that org's custom objects and fields. While this provides better compile-time safety for internal, single-org integrations, it is unsuitable for an application intended for "more than one Salesforce org" because the WSDL would be invalid for any org that doesn't have the exact same metadata. Option C is a general term; the actual choices provided by Salesforce for integration are the Partner or Enterprise WSDLs. Therefore, for maximum flexibility and reusability across a multi-org landscape, the Partner WSDL is the industry standard.
問題 #105
Northern Trail Outfitters (NTO) has recently changed its Corporate Security Guidelines requiring all cloud applications to pass through a secure firewall before accessing on-premise resources. NTO is evaluating middleware solutions. Which consideration should an integration architect evaluate before choosing a middleware solution?
答案：A
解題說明：
When corporate guidelines mandate a firewall-protected entry point for cloud traffic, the middleware architecture must include a component capable of residing in a Demilitarized Zone (DMZ) or perimeter network. The architect must evaluate the solution's API Gateway capabilities.
A secure API Gateway acts as the intermediary that terminates external (cloud) TLS connections and inspects incoming traffic before proxying it to internal systems. It allows the security team to implement:
IP Whitelisting: Ensuring only Salesforce's IP ranges can access the gateway.
Mutual Authentication: Using certificates to verify that the request is genuinely coming from the Salesforce org.
Rate Limiting: Protecting on-premise resources from being overwhelmed by cloud requests.
Option A (OAuth) is an authorization framework and does not satisfy the network-level firewall requirement on its own. Option B (ODBC) is an internal database protocol that should generally never be exposed to a cloud-facing firewall due to security risks. By prioritizing a solution with a hardened API Gateway, the architect ensures that NTO meets its new security mandates while providing a scalable and secure bridge for Salesforce to access back-office services.
問題 #106
An enterprise architect has requested the Salesforce integration architect to review the following (see diagram and description) and provide recommendations after carefully considering all constraints of the enterprise systems and Salesforce Platform limits.
There are multiple eligibility systems that provide this service and are hosted externally.34 However, their current response times could take up to 90 seconds to process and return.
These eligibility systems can be acc8essed through APIs orchestrated via ESB (MuleSoft).
All requests from Salesforce must traverse the customer's API Gateway layer, which imposes a constraint of timing out requests after 9 seconds.
Which recommendation should the integration architect make?
答案：C
