正解:A
In ServiceNow, thewait timefor end users is influenced by theround-trip timebetween the client (browser) and the server. The round-trip consists of two key activities:
Request- The client sends a request to the server (e.g., when a user opens a record, submits a form, or performs an action).
Response- The server processes the request and sends back the required data to the client.
This cycle directly affects the perceived performance of the ServiceNow instance, as delays in request processing or data retrieval can lead to a slower user experience.
Minimizing client-server interactionsis a best practice for optimizing performance.
Using GlideAjax or Asynchronous Callscan help reduce unnecessary round-trips.
Client-side scripting best practices(e.g., reducing the number of server lookups) improve response times.
Performance Considerations:Incorrect Answers Explanation:B.Save + Update- Saving and updating are database operations, but they do not define the full round-trip.
C).Write + Read- Writing and reading refer to database interactions, not the client-server exchange process.
D).Submit + Query- Submission and querying are user actions, but they do not encompass the entire round- trip process.
E).Insert + Verify- Inserting a record and verifying it are database actions, not the round-trip process.
