Quick Answer
The answer is to enable caching for widgets. This is the best practice approach because widget caching stores the rendered HTML output in memory after the first request, so subsequent users see the cached version without re-executing server-side scripts or database queries, directly reducing server load and improving page load times during peak usage. On the ServiceNow Certified System Administrator CSA exam, this question tests your understanding of performance optimization techniques that do not alter the user interface—a common trap is choosing to modify UI policies or client scripts, which change the interface and miss the core caching concept. Remember that caching is a server-side, non-visual fix that preserves the existing user experience while boosting speed. A simple memory tip: “Cache the widget, not the look—keep the UI, speed up the book.”
This SNOW-CSA practice question tests your understanding of self-service and automation.

Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Increase the instance size
Why wrong: This may not address the root cause and is costly.
Remove all widgets from the homepage
Why wrong: This reduces functionality and user engagement.
Disable the search feature
Why wrong: Disabling search harms usability.
Enable caching for widgets
Caching reduces server calls and improves load times.

Correct answer & explanation
Enable caching for widgets
Enabling caching for widgets reduces server load and improves page load times by storing rendered widget output in memory, allowing subsequent requests to serve cached content without re-executing the underlying scripts or queries. This directly addresses performance degradation during peak usage without altering the user interface, making it the best practice approach.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
ServiceNow often tests the misconception that performance issues must be solved by scaling infrastructure or removing features, rather than optimizing existing components through caching or other non-intrusive techniques.
Detailed technical explanation
Widget caching in ServiceNow leverages the 'Cache' property on widget instances or the 'Client Cache' setting in the widget's server script, which stores the rendered HTML and data in the system cache (e.g., using the 'gs.getCache()' API). This is particularly effective for widgets that display static or slowly changing data, such as knowledge articles or announcements, where the cache can be invalidated via a cache flush or scheduled job. In a real-world scenario, a portal with a heavy 'Top Articles' widget might see a 50% reduction in server response time after enabling caching, as the widget no longer queries the database on every page load.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the SNOW-CSA exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
