You are working on a project to deploy a critical multitier web application. The application is as follows:
In the scenario described, the SAN space is limited. Which of the following options would help
save space while still providing the infrastructure shown above?
A.
Confirm that 80 GB is actually used on the servers in each tier and configure thin provisioning
to save space.
B.
Reduce the amount of memory in each web server by 2 GB to reduce the amount of swap
space created.
C.
Create a resource pool hierarchy for the web, processing, and database tiers in the application
and configure a reservation for the total amount in each tier. This would reduce the amount of
space used within the datastore.
Explanation:
C is retarded. Reservation pools have nothing to do with the size consumed on datastores. The VM would still take the same size configured in ram for swap space. The answer is A.
Answer is C not A , as the reservation for the VM will prevent creation on the swap file which intern will save space on the datastore.
