A company's cloud-based single page application consolidates data local to the application with data from on premise and 3rd party systems. The diagram below typifies the application's combined use of synchronous and asynchronous calls.

The company wants to use the average response time of its application's user interface as a basis for certain alerts. For this purpose, the following occurs:
1. Log every call's start and finish date and time to a central analytics data store.
2. Compute response time uniformly as the difference between the start and finish date and time - A to H in the diagram.
Which computation represents the end-to-end response time from the user's perspective?

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?

Universal Containers acquires several companies and decides to consolidate all customer service systems used by the acquired companies into one Salesforce Service Cloud.

Different requests captured by different customer service systems could belong to common accounts in Salesforce, so care must be taken to avoid creating duplicate accounts. Which two API options should be considered to load cases into Salesforce that would be safe from record -locking issues? Choose 2 answers
