Answer 1

If I understand you correctly...
By Text: KPI Types
By XPath: //a[text()='KPI Types']
In c#:
driver.FindElement(By.LinkText("KPI Types")).Click();
driver.FindElement(By.XPath("//a[text()='KPI Types']")).Click();
Or if you want to restrict it specifically to the Configuration list:
By XPath: //li[text()='Configuration']//a[text()='KPI Types']
In c#:
driver.FindElement(By.XPath("//li[text()='Configuration']//a[text()='KPI Types']")).Click();
Does that answer your question?
