Extracted text: Which of the following is true about hosting platforms? Poorly executing database queries can be solved by updating statistics and/or adding an appropriate index O Since HTML, JavaScript and CSS can execute on the browser, your code could be impacted by a different browser or even version of a browser All requests to a web or application server are typically logged and can include the IP of the client, the HTTP request method, the HTTP response code, URI, etc. If the CPU utilization % is low, there is no paging and the I/O performance is fine, then the performance issue is not within the database server Because the HTTP protocol is "sessionless", each web server child process only handles one HTTP request and then ends Most often, application servers also include at least a thin HTTP (web) server All database reads require a read or shared lock in order to proceed The most useful portion of a stack trace is always at the bottom Because they are hosted in the cloud, applications that use Paas services do not need to worry about instrumenting their code
