A Technical Consultant is implementing an experience site for a government agency where they will...

To ensure that a government agency's experience site can handle a high volume of grant applications during a specific window, the following steps or tools should be leveraged:

Identify expensive processes to offload to asynchronous processes (Option C). This approach helps manage resource-intensive tasks without impacting the user experience on the front end, particularly important during high-traffic periods.

Implement CDN and waiting rooms (Option D). Content Delivery Networks (CDNs) can significantly improve load times for users by caching content at edge locations closer to users. Waiting rooms can be used to manage access to the site during peak times, preventing overload.

Analyze and test the application for the expected load with a load testing tool (Option E). Prior to going live, it is crucial to simulate expected traffic using load testing tools to ensure that the site can handle the surge in users without performance degradation.

Option A, while important, primarily focuses on code quality rather than scalability and performance under load. Option B, setting up IP restrictions, does not directly contribute to handling a surge in site traffic but rather controls access based on user location or network, which may not be relevant to the scenario described.
