You are a site administrator who has identified a bottleneck on a small site. You find that
the processor is overburdened, the RAM is too small and NIC is approaching 100%
capacity. You are also considering installing a second virtual server. Which of the
following choices is the best step to resolve the bottleneck?

A.
Upgrade all of the components on your web server.

B.
Install the replication components that distribute the command for service across
multiple servers.

C.
Upgrade your software with an improved version.

D.
Purchase third party software to help identify bottlenecks in the future.

Explanation:
It is obvious that the hardware resources are no longer sufficient to
run the server, and a total upgrade of all components, or replacement of the server
is needed.
Incorrect Answers:
B: Replication components may distribute some of the work, but the replication servicesalso
require resource. And we are looking to install another virtual server, so the issueremains, the
server needs upgrading.
C: Upgrading the software will not improve the situation. Not unless the software wasmassively
inefficient, but that most likely won’t relieve the NIC traffic. A softwareupgrade correcting the
situation is unlikely.
D: Knowing where the bottlenecks in the future doesn’t fix the problems of today.Identification of
the bottlenecks in the future my be desirable, but it doesn’t resolve thecurrent bottleneck, which is
the task that the
