You deployed your company website using Elastic Beanstalk and you enabled log file rotation to S3. An Elastic
Map Reduce job is periodically analyzing the logs on S3 to build a usage dashboard that you share with your
CIO.
You recently improved overall performance of the website using Cloud Front for dynamic content delivery and
your website as the origin.
After this architectural change, the usage dashboard shows that the traffic on your website dropped by an order
of magnitude. How do you fix your usage dashboard’?
A.
Enable Cloud Front to deliver access logs to S3 and use them as input of the Elastic Map Reduce job.
B.
Turn on Cloud Trail and use trail log tiles on S3 as input of the Elastic Map Reduce job
C.
Change your log collection process to use Cloud Watch ELB metrics as input of the Elastic Map Reduce job
D.
Use Elastic Beanstalk “Rebuild Environment” option to update log delivery to the Elastic Map Reduce job.
E.
Use Elastic Beanstalk ‘Restart App server(s)” option to update log delivery to the Elastic Map Reduce job.
