A data engineering manager has noticed that each of the queries in a Databricks SQL dashboard takes a few minutes to update when they manually click the ""Refresh"" button. They are curious why this might be occurring, so a team member provides a variety of reasons on why the delay might be occurring.
Which of the following reasons fails to explain why the dashboard might be taking a few minutes to update?
a) Network congestion causing delays in fetching data from external sources.
b) Insufficient cluster resources leading to slow query execution.
c) Complex SQL queries requiring extensive computation.
d) The browser cache is not properly configured, leading to slow rendering of results.
