Q21. Which Salesforce API is best for creating custom REST based integration endpoints in Apex

1. Metadata API
2. Apex REST
3. Bulk API
4. Tooling API

Correct Answer: 2. Apex REST

Explanation

Apex REST allows developers to expose custom Salesforce business logic through REST based endpoints implemented in Apex. Metadata API manages Salesforce configuration. Bulk API is optimized for high volume data operations. Tooling API supports development and setup related activities. Apex REST is therefore the correct answer because an integration may require custom processing that standard Salesforce APIs do not provide directly. Architects should still prefer standard APIs when they meet requirements because custom endpoints create additional code testing maintenance security and governor limit considerations.

Q22. Which mechanism is best for securely storing an external service endpoint and authentication configuration in Salesforce

1. Hard coded Apex values
2. Custom text fields
3. User browser storage
4. Named Credentials

Correct Answer: 4. Named Credentials

Explanation

Named Credentials provide a controlled way to define external endpoints and related authentication settings used by Salesforce callouts. Hard coded values make maintenance and security more difficult. Custom text fields are not designed to manage sensitive authentication configuration. Browser storage is inappropriate for server side integration credentials. Named Credentials is therefore the correct answer because they separate connection details from business logic and simplify secure callout configuration. Architects can also use appropriate external credential capabilities and permission controls so different integrations receive only the access required for their intended external services.

Q23. Which Salesforce API style is most appropriate for standard record operations using web resources

1. REST API
2. Metadata API
3. Tooling API
4. Analytics API

Correct Answer: 1. REST API

Explanation

REST API provides resource based access to Salesforce records and is commonly used for standard create read update and delete operations. Metadata API manages configuration. Tooling API focuses on development related objects and tools. Analytics API supports analytics related use cases. REST API is therefore the correct answer because it offers a widely supported and straightforward interface for external applications that need to interact with Salesforce business data. Architects should still evaluate data volume transaction requirements and API usage because another interface may be more suitable for very large or specialized workloads.

Q24. Which pattern should be used when an external application starts a long running process in Salesforce and does not need an immediate business result

1. Synchronous request and reply
2. User interface integration
3. Asynchronous remote process invocation
4. Data virtualization

Correct Answer: 3. Asynchronous remote process invocation

Explanation

Asynchronous remote process invocation allows an external system to request processing without holding the caller open until the work finishes. Synchronous request and reply requires an immediate response. User interface integration combines user experiences. Data virtualization exposes external data without copying it. Asynchronous remote process invocation is therefore the correct answer because long running work should generally be decoupled from the initiating request when an immediate business result is unnecessary. Architects should define status tracking failure handling retries and how the initiating system learns whether the requested process ultimately succeeded.

Q25. Which integration design best handles messages that repeatedly fail processing

1. Dead letter handling
2. Unlimited immediate retries
3. Disable logging
4. Ignore failed messages

Correct Answer: 1. Dead letter handling

Explanation

Dead letter handling moves repeatedly failing messages into a controlled location for investigation and recovery after normal retry attempts are exhausted. Unlimited retries can overload systems and repeatedly process permanently invalid data. Disabling logging reduces visibility. Ignoring failed messages can create data inconsistency. Dead letter handling is therefore the correct answer because reliable integrations need a clear method for separating persistent failures from normal processing. Support teams can inspect the failed message identify the cause correct the underlying problem and replay the transaction when appropriate.

Q26. Which Salesforce integration approach is appropriate when an external system needs to notify Salesforce about business events

1. Dashboard refresh
2. Report export
3. Manual data entry
4. Inbound API integration

Correct Answer: 4. Inbound API integration

Explanation

Inbound API integration allows an external application to call Salesforce and submit information or trigger approved processing. Dashboard refresh and report export are reporting functions. Manual data entry does not provide automated system integration. Inbound API integration is therefore the correct answer because external systems often need to notify Salesforce about orders payments account updates or other business events. Architects should select an appropriate Salesforce API authentication model transaction design and error handling strategy based on the data volume timing and business processing requirements.

Q27. Which design best supports reliable matching when an external system updates Salesforce records through upsert

1. Record owner name
2. Unique external ID field
3. Created date
4. Display name

Correct Answer: 2. Unique external ID field

Explanation

A unique external ID field provides a stable cross system key that Salesforce can use to determine whether an incoming record should be inserted or update an existing record. Owner names creation dates and display names may not be unique or stable. Unique external ID field is therefore the correct answer because upsert processing requires dependable record matching. Architects should define which system owns the identifier and ensure uniqueness rules remain consistent. Stable identifiers also simplify reconciliation duplicate prevention and troubleshooting across integrated systems.

Q28. Which architecture reduces transformation logic duplicated across several Salesforce integrations

1. Separate custom transformation in every endpoint
2. Manual spreadsheet mapping
3. Centralized transformation in middleware
4. Shared user credentials

Correct Answer: 3. Centralized transformation in middleware

Explanation

Centralized transformation in middleware allows common mapping rules to be maintained in one integration layer instead of repeated independently in every endpoint. Separate custom transformations increase maintenance effort and inconsistency risk. Manual spreadsheets are difficult to operate as runtime integration logic. Shared credentials weaken security. Centralized transformation in middleware is therefore the correct answer when several systems require similar canonical mapping or protocol conversion. Architects should still avoid unnecessary centralization when simple direct integrations can satisfy requirements with less complexity.

Q29. Which approach is best for notifying subscribers that a Salesforce record changed without sending the full database repeatedly

1. Full nightly export
2. Manual reporting
3. Direct database access
4. Change event messaging

Correct Answer: 4. Change event messaging

Explanation

Change event messaging allows downstream consumers to receive notifications about relevant Salesforce record changes instead of repeatedly processing the entire data set. Full nightly exports transfer more data than necessary. Manual reporting is not automated synchronization. Direct database access is not an appropriate Salesforce integration pattern. Change event messaging is therefore the correct answer because it supports efficient event driven synchronization. Architects should consider event ordering replay handling consumer outages and whether the subscriber requires every field or only enough information to retrieve or process the changed record.

Q30. Which integration concern should be evaluated before making synchronous callouts from a user transaction

1. External service latency
2. Dashboard layout
3. Report folder ownership
4. Email template style

Correct Answer: 1. External service latency

Explanation

External service latency directly affects a synchronous user transaction because Salesforce must wait for the remote response before the business process can continue. Dashboard layout report folder ownership and email template style do not determine callout responsiveness. External service latency is therefore the correct answer because a slow or unreliable dependency can create poor user experience timeouts and failed transactions. Architects should evaluate expected response times availability timeout handling and whether the process truly requires an immediate answer or could be redesigned asynchronously.

Q31. Which Salesforce capability can expose records from an external source as if they were Salesforce objects

1. Static resources
2. Email Services
3. Salesforce Connect
4. Approval Processes

Correct Answer: 3. Salesforce Connect

Explanation

Salesforce Connect allows supported external data sources to be represented in Salesforce through external objects without requiring complete local replication. Static resources store files. Email Services process inbound email. Approval Processes manage business approvals. Salesforce Connect is therefore the correct answer because it supports data virtualization when the external system should remain the system of record. Architects should consider remote source performance availability security and query capabilities because user interactions with external objects can depend directly on the external system response.

Q32. Which integration design best protects Salesforce when an external system sends traffic bursts

1. Increase every user permission
2. Throttling and queueing
3. Disable authentication
4. Remove error handling

Correct Answer: 2. Throttling and queueing

Explanation

Throttling and queueing control how quickly incoming work reaches Salesforce and can smooth traffic bursts that might otherwise consume excessive API or processing capacity. Increasing permissions does not improve traffic management. Disabling authentication creates serious security risk. Removing error handling reduces reliability. Throttling and queueing is therefore the correct answer because external systems may generate short periods of very high volume even when normal traffic is moderate. A controlled integration layer can buffer requests enforce limits and process them at a sustainable rate while preserving transaction order where necessary.

Q33. Which principle is most important when choosing the system that owns a shared customer attribute

1. Define a system of record
2. Let every system update independently
3. Use the longest field value
4. Select the newest application

Correct Answer: 1. Define a system of record

Explanation

Defining a system of record establishes which application is authoritative for a particular business entity or attribute. Allowing every system to update independently can create conflicts. Field length and application age do not determine data ownership. Define a system of record is therefore the correct answer because integrations need clear ownership rules to prevent competing updates and inconsistent information. Architects should document which system creates maintains and distributes important data elements and define how exceptions reconciliation and corrections are handled across participating applications.

Q34. Which API approach is useful when a client needs multiple related Salesforce operations in one request

1. Metadata deployment
2. Streaming only
3. Composite API
4. Static resource request

Correct Answer: 3. Composite API

Explanation

Composite API allows a client to combine multiple related Salesforce API operations into one request and can reduce network round trips. Metadata deployment manages configuration. Streaming interfaces deliver events. Static resource requests retrieve stored files. Composite API is therefore the correct answer because integrations sometimes need several dependent record operations executed efficiently within a coordinated request. Architects should understand the behavior and limits of the selected composite resource and should not use it merely to hide poorly designed transaction boundaries or excessive application coupling.

Q35. Which approach best secures outbound Salesforce callouts when certificate based trust is required

1. Anonymous endpoint
2. Plain text password in Apex
3. Shared browser cookie
4. Certificate based authentication

Correct Answer: 4. Certificate based authentication

Explanation

Certificate based authentication allows systems to establish trust using cryptographic certificates rather than embedding ordinary passwords in application code. Anonymous endpoints provide insufficient identity control. Plain text passwords in Apex create serious security and maintenance problems. Shared browser cookies are inappropriate for server integrations. Certificate based authentication is therefore the correct answer when the external service requires certificate based trust. Architects should manage certificate lifecycle expiration rotation storage and endpoint validation carefully so integrations continue operating securely over time.

Q36. Which pattern is best when Salesforce should request current pricing from another system only when a user needs it

1. Full daily replication
2. Synchronous service call
3. Manual spreadsheet upload
4. Metadata deployment

Correct Answer: 2. Synchronous service call

Explanation

A synchronous service call is appropriate when Salesforce users need a current value from an external system and the business process requires the result immediately. Full replication may create stale duplicate data. Manual uploads are operationally inefficient. Metadata deployment is unrelated to pricing information. Synchronous service call is therefore the correct answer because pricing can be retrieved at the moment of need from the authoritative system. Architects should ensure the external service can meet required latency and availability targets and should define timeout and fallback behavior.

Q37. Which integration design improves traceability when the same transaction passes through Salesforce and middleware

1. Shared correlation ID
2. Separate random IDs at every step
3. Disable transaction logging
4. Use user display names

Correct Answer: 3. Shared correlation ID

Explanation

A shared correlation ID follows the same transaction across Salesforce middleware and downstream applications so related log entries can be connected. Separate unrelated identifiers make troubleshooting more difficult. Disabling logging removes visibility. User display names are not reliable transaction identifiers. Shared correlation ID is therefore the correct answer because distributed integrations often produce logs in several systems. A consistent identifier allows support teams to reconstruct the complete processing path identify failures and measure end to end timing without manually guessing which records belong to the same transaction.

Q38. Which error handling design is most appropriate for a temporary external service timeout

1. Delete the source record
2. Disable the integration
3. Ignore the failure
4. Retry using a controlled policy

Correct Answer: 4. Retry using a controlled policy

Explanation

A controlled retry policy allows an integration to retry transient failures such as temporary service timeouts without immediately treating the transaction as permanently failed. Deleting the source record risks data loss. Disabling the integration affects unrelated transactions. Ignoring the failure causes inconsistency. Retry using a controlled policy is therefore the correct answer because temporary failures are normal in distributed systems. Architects should define retry limits delay strategy error categories and final failure handling so persistent problems eventually move to manual or automated recovery instead of retrying forever.

Q39. Which design is best when an integration must process related updates as one business unit

1. Independent unrelated requests
2. Transaction boundary definition
3. Anonymous processing
4. Manual reporting

Correct Answer: 2. Transaction boundary definition

Explanation

Transaction boundary definition identifies which related operations must succeed or fail together to preserve business consistency. Independent unrelated requests may leave partial updates when one operation fails. Anonymous processing weakens security. Manual reporting does not provide transactional behavior. Transaction boundary definition is therefore the correct answer because integration architects must understand which records and actions form one logical business transaction. When systems cannot share a single database transaction architects may need compensating actions idempotency status tracking or orchestration to maintain consistency across system boundaries.

Q40. Which approach best separates external system details from Salesforce business processes

1. Hard code every endpoint in business logic
2. Expose external passwords to users
3. Duplicate mapping logic in every flow
4. Integration abstraction layer

Correct Answer: 4. Integration abstraction layer

Explanation

An integration abstraction layer hides external endpoint protocols and implementation details behind a stable interface used by Salesforce business processes. Hard coding endpoints creates tight coupling. Exposing passwords is insecure. Duplicating mapping logic increases maintenance effort. Integration abstraction layer is therefore the correct answer because external systems can change independently while Salesforce continues using a consistent integration contract. This design can simplify testing versioning and substitution of downstream services. Architects should avoid unnecessary abstraction when the integration is simple and unlikely to change.
