질문 # 123
Northern Trail Outfitters needs to use Shield Platform Encryption to encrypt social security numbers in order to meet a business requirement. Which action should an integration architect take prior to the implementation of Shield Platform Encryption?
정답：A
설명：
Prior to implementing Shield Platform Encryption, the most critical step for an Integration Architect is to perform a comprehensive Review of Shield Platform Encryption configurations and their impact on existing platform functionality. Encryption at rest is not a "set-and-forget" feature; it changes how the Salesforce database interacts with various features, and failing to review these limitations beforehand can lead to significant business disruption.
Salesforce documentation emphasizes that encryption affects several core areas:
SOQL/SOSL Limitations: Encrypted fields have restricted capabilities in WHERE, GROUP BY, and ORDER BY clauses.1 For example, if Social Security Numbers (SSNs) are encrypted using Probabilistic Encryption, they cannot be filtered or sorted in a query.2 This could break existing integrations or reports that rely on finding specific records by SSN.
Search Functionality: While Salesforce supports searching for encrypted data, there are specific behaviors to consider regarding how search indexes are built and updated.
AppExchange and Managed Packages: If the SSN field is used by a third-party app or a managed package, encrypting it might cause those external tools to fail if they are not designed to handle encrypted data types.
Field Attributes: Encrypted fields cannot be used as Unique or External IDs if using the probabilistic scheme, which is a vital consideration for data synchronization architectures.3 Therefore, the architect must first conduct a Business Impact Analysis. This includes identifying where the sensitive data (SSNs) is used in Apex code, Flows, validation rules, and reports. By reviewing the configurations and functional limitations first, the architect can decide between Probabilistic (higher security) and Deterministic (allows filtering) encryption strategies.4 Option A is a step taken during or after implementation (Background Encryption), and Option C is an anti-pattern, as encrypting "everything" leads to unnecessary performance overhead and massive functional loss. Only after a thorough review can the architect safely proceed with the technical implementation of Shield.
질문 # 124
Northern Trail Outfitters wants to use Salesforce as a front end for creating accounts using the lead-to-opportunity process. An order is created in Salesforce when the opportunity is Closed/Won, but the back-end Enterprise Resource Planning (ERP) system is the data master for order. The customer wants to be able to see within Salesforce all the stages of order processing like Order Created, Order Shipped, and Order Paid that are within the retention window. Which message durability consideration should an integration architect make when designing a solution to meet these business requirements?
정답：A
설명：
When designing a solution that requires Salesforce to receive and display updates from a back-end ERP (such as order status changes), message durability is a critical factor for ensuring data consistency. In an event-driven architecture using Platform Events or Change Data Capture (CDC), Salesforce utilizes an event bus to handle these incoming notifications.
For high-volume event messages, the Salesforce platform provides a native 72-hour (3-day) retention window. This is a significant architectural advantage for several reasons:
System Resilience: If the Salesforce org or the integration middleware experiences a temporary disruption or is undergoing maintenance, the event messages published by the ERP remain stored in the bus for up to 3 days.
Data Recovery: Once the connection is restored, the subscribing system (Salesforce) can use the Replay ID to catch up on any missed events from the last 72 hours, ensuring that order stages like "Order Shipped" or "Order Paid" are not missed.
SLA Management: This 3-day window exceeds the 24-hour limit of older technologies like PushTopics or Outbound Messaging (Option A), providing more breathing room for disaster recovery scenarios.
While ReplayID -1 (Option C) is used to subscribe only to new events published after the subscription starts, it does not address the durability or retention of historical events needed for recovery. By highlighting the 72-hour retention window, the integration architect provides a design that is robust against outages and guarantees that the "System of Engagement" (Salesforce) stays synchronized with the "System of Record" (ERP).
질문 # 125
Northern Trail Outfitters needs to send order and line items directly to an existing finance application webservice when an order is fulfilled. It is critical that each order reach the finance application exactly once for accurate invoicing. Which solution should an architect propose?
정답：A
설명：
Achieving "exactly once" delivery and high reliability in a critical finance integration requires an asynchronous pattern that provides better control and error handling than standard @future methods. Queueable Apex is the architecturally preferred solution for this scenario.
Queueable Apex offers several advantages over @future methods:
Stateful tracking: Unlike @future, Queueable jobs return a Job ID, allowing the system to monitor progress and verify completion.
Chaining: You can chain jobs to process records sequentially, which helps maintain the integrity of order and line item data.
Complex Data Types: Queueables can accept complex objects as parameters, making it easier to pass high-fidelity order data than the primitive types required by @future.
Option A is unreliable because it relies on human intervention for retries, which is prone to error and does not scale. Option C is less desirable because @future methods cannot be monitored as effectively and lack the ability to return a Job ID for subsequent tracking.
To ensure accurate invoicing, the architect should design the Queueable class with a custom error handling process that includes logging failures and a retry mechanism. Additionally, to prevent duplicate invoicing, the finance application should be designed with an Idempotency check (using a unique Order ID from Salesforce) to ensure that if a retry is sent, the system recognizes the duplicate and does not create a second invoice. This combination of Queueable Apex and idempotency provides the highest level of reliability for critical financial transactions.
질문 # 126
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?
정답：A
설명：
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.
질문 # 127
Universal Containers (UC) is a leading provider of management training globally. UC embarked on a Salesforce transformation journey to allow students to register for courses in the Salesforce Community. UC has a learning system that masters all courses and student registration. UC requested a near real-time feed of student registration from Salesforce to the learning system. The integration architect recommends using Salesforce Platform Events. Which API should be used for the Salesforce pl1atform event solution?
정답：A
설명：
Salesforc30e Platform Events are built on top of a highly scalable, event-driven messaging architecture designed to enable real-time communication between apps. To consume these events from outside Salesforce-such as from a legacy learning system-clients must use the Streaming API.
The Streaming API is the technical foundation for receiving event notifications in a Publish/Subscribe model. It utilizes the CometD protocol or the newer gRPC-based Pub/Sub API to maintain a persistent connection between the external client and Salesforce. When a student registers for a course in the Salesforce Community, a Platform Event is "published" to the event bus. The learning system, acting as a "subscriber," remains connected via the Streaming API and receives the event message instantly without needing to poll Salesforce for updates.
This architecture is ideal for "near real-time" requirements because it eliminates the overhead of traditional point-to-point integrations. While the REST and SOAP APIs (Options A and B) can be used to publish events into Salesforce, they are not designed to receive unsolicited notifications from the platform. By using the Streaming API, the integration architect ensures the solution is both responsive and efficient, as Salesforce only pushes data when a relevant event occurs. Furthermore, because Platform Events provide a retention window, the Streaming API allows the learning system to use a Replay ID to catch up on any registration events missed during a brief network outage.
