Question
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
