Explanation
Option C is correct because including selective criteria in query filters can improve the performance of the integration. Selective criteria are filters that reduce the number of records that need to be scanned by the query optimizer, such as indexed fields, standard indexes, or custom indexes. Selective criteria can help the query run faster and avoid hitting the query timeout limit or the query row limit.
Option D is correct because removing the sharing restrictions can improve the performance of the integration. Sharing restrictions are filters that limit the access to records based on the user's role, profile, or sharing rules. Sharing restrictions can add complexity and overhead to the query execution, as they require additional joins and calculations. Removing the sharing restrictions can simplify the query and reduce the number of records that need to be processed.
Option A is incorrect because including non-selective criteria in query filters can degrade the performance of the integration. Non-selective criteria are filters that do not reduce the number of records that need to be scanned by the query optimizer, such as non-indexed fields, formula fields, or OR conditions. Non-selective criteria can cause the query to run slower and hit the query timeout limit or the query row limit.
Option B is incorrect because removing the query filters can degrade the performance of the integration.
Query filters are conditions that specify which records to retrieve from the database, such as WHERE clauses or LIMIT clauses. Query filters can help the query run faster and avoid retrieving unnecessary or unwanted data. Removing the query filters can increase the number of records that need to be processed and transmitted by the integration.

Explanation
The end-to-end response time from the user's perspective is the time elapsed between the user's request and the user's receipt of the final response. In the diagram, this corresponds to the sum of A and H, which are the durations of the synchronous calls from the user interface to the cloud-based application and back. The other durations (B to G) are either internal to the cloud-based application or asynchronous calls that do not affect the user's perception of response time. Therefore, the correct answer is D, because it represents the sum of A and
H.

Explanation
Option D is correct because Tooling API is the Salesforce API that can be used to retrieve code coverage and test results for Apex classes and triggers. Tooling API provides REST and SOAP interfaces to access metadata about code, execute tests, and get test results12 Option A is incorrect because SOAP API is a Salesforce API that can be used to create, retrieve, update, or delete records, but not to get code coverage and test results. SOAP API uses a WSDL file to define the parameters for accessing data through the API3 Option B is incorrect because Analytics REST API is a Salesforce API that can be used to access data from reports and dashboards, but not from code coverage and test results. Analytics REST API provides a programmatic way to interact with analytics features such as lenses, datasets, and dashboards4 Option C is incorrect because Metadata API is a Salesforce API that can be used to retrieve, deploy, create, update, or delete customization information, such as custom object definitions and page layouts, but not code coverage and test results. Metadata API is mainly used for development tools or backup tools5 References: 1: Introducing Tooling API 2: Tooling API Examples 3: SOAP API Developer Guide 4: Analytics REST API Developer Guide 5: Metadata API Developer Guide

Explanation
These are three considerations that an Integration Architect should consider when recommending Platform Event as an Integration solution. Platform Events are a type of event-driven architecture that allows you to publish and subscribe to custom events in Salesforce and external systems. Platform Events have some limitations and features that an Integration Architect should be aware of, such as:
Inability to query event messages using SOQL. Platform Events are not stored in Salesforce database, but in an event bus that retains them for 24 hours. You cannot use SOQL to query event messages, but you can use the EventLogFile object or the Event Monitoring feature to access them.
Inability to create a Lightning record page for platform events. Platform Events are not standard or custom objects, but a special type of sObject that can be inserted into the event bus. You cannot create a Lightning record page for platform events, but you can use Apex triggers, Lightning web components, or CometD clients to subscribe to them.
When you delete an event definition, it's permanently removed and can't be restored. An event definition is a metadata type that defines the schema and properties of a platform event message. You can create or modify event definitions in Salesforce Setup or using Metadata API. However, if you delete an event definition, it's permanently removed from your org and can't be restored. You also lose access to any event messages that use that event definition.
