Salesforce Updated Integration-Architect Exam Questions and Answers by alanna

The error “Max CPU time exceeded” occurs when a batch of records takes more than 10 minutes to process in the Bulk API. Using a smaller batch size can reduce the processing time and avoid this error. However, there are some trade-offs to consider when using a smaller batch size, such as:

• Answer A is valid because a smaller batch size may cause record-locking errors if multiple batches try to update the same records or records that are related by a lookup or master-detail relationship. This can result in concurrency issues and data inconsistency1
• Answer B is valid because a smaller batch size may increase the time required to execute bulk jobs, as more batches need to be created and processed sequentially. This can affect the performance and efficiency of the integration1
• Answer C is not valid because a smaller batch size may not exceed the concurrent API request limits, as the Bulk API does not count against the concurrent request limit. The Bulk API has its own limit on the number of batches that can be queued or in progress, which is 5,000 per rolling 24-hour period2
• Answer D is not valid because a smaller batch size can trigger “Too many concurrent batches” error only if the number of batches exceeds the limit of 5,000 per rolling 24-hour period. This error is not related to the parallel mode of the Bulk API, which allows up to 10 batches to be processed simultaneously

 Reducing the batch size of asynchronous BULK API and submitting the legacy system in parallel mode are two recommendations that can improve the integration performance. The BULK API is designed to handle large-scale data loads, but it can also cause latency issues if the batch size is too large or the network bandwidth is insufficient. Reducing the batch size can help to avoid timeouts and improve throughput. Submitting the legacy system in parallel mode can also speed up the integration process by allowing multiple batches to be processed concurrently, as long as there are no dependencies or conflicts between them.

The recommendations that the Salesforce integration architect should make to fulfill the requirements around caching, queuing, error handling, alerts, retries, event handling, etc. are based on the best practices and capabilities of the middleware tools. The recommendation B is valid because middleware tools can provide true message queueing for integration scenarios that require asynchronous processing, guaranteed delivery, load balancing, etc. The recommendation D is valid because middleware tools can handle various events that may occur during the integration process, such as logging errors, sending notifications, triggering recovery actions, etc. The recommendation E is valid because middleware tools can support the publish/subscribe pattern for event-driven integration, where the middleware can route messages from publishers to subscribers based on topics or filters. The recommendation A is not valid because transforming a fire-and-forget mechanism to request-reply does not improve performance, but rather increases the latency and complexity of the integration. The recommendation C is not valid because message transformation and protocol translation are tasks that are better suited for middleware tools than Salesforce, as they can handle different formats and protocols more efficiently and flexibly23

 The best solutions for minimizing potential downtime for users in this situation are to use named credentials and an enterprise ESB. Named credentials allow you to store the URL and authentication parameters of an external service in one definition, and then use it in Apex callouts or declarative integrations. If the URL of the external service changes, you only need to update the named credential once, and all the integrations that use it will be updated automatically. An enterprise ESB is a middleware layer that acts as a broker between different systems and services. It can provide routing, transformation, orchestration, and monitoring capabilities for integrations. If the URL of an external service changes, you only need to update the ESB configuration once, and all the integrations that use it will be updated automatically. Option B is not correct because remote site settings only allow you to specify the domains that are allowed for callouts from your org. They do not store any authentication parameters or provide any routing or transformation capabilities. Option C is not correct because content security policies are used to control what resources can be loaded on a Visualforce or Lightning page. They do not store any authentication parameters or provide any routing or transformation capabilities. References:
