A company's application is experiencing performance degradation due to increased read traffic on its primary database hosted in the North Virginia region. The user base is distributed across North America and Europe. The company wishes to optimize read performance for these users. Which approach should be adopted to enhance the application's read traffic handling capacity while also addressing the geographical distribution of the user base?
Transition to a higher provisioned IOPS configuration for the current database deployment.
Launch an additional database in the same region as the primary without enabling replication features.
Upscale the compute and memory resources of the current primary database to handle the increased traffic.
Establish replicas in regions that are geographically closer to users in North America and Europe to handle read traffic efficiently.
