A customer site is experiencing poor performance. Which of the following options is most likely to help performance?

The option that addresses performance issues at a customer site effectively involves increasing the memory and CPUs on the search head(s) and adding additional indexers. This approach is justified because performance bottlenecks in Splunk can often be traced back to insufficient hardware resources on search heads and indexers.

By increasing the memory and CPU allocations, you enhance the ability of the search heads to handle complex queries and greater loads. Adding more indexers allows for better distribution of the indexing workload, leading to quicker retrieval times for search results.

Improving hardware resources not only supports a higher volume of concurrent searches but also allows for efficient data retrieval from indexed data. This can lead to improved response times for end-users and an overall enhancement in the system's performance.

The focus on resource enhancement directly correlates with improved Splunk performance, which is critical in environments where data is being constantly ingested and analyzed in real-time.
