A company with a very high virtualization percentage decided to move to a cloud architecture.
They hired a cloud service provider (CSP) to provide infrastructure on demand. The company
moved the web front-end of a tightly coupled service to the CSP. Now users are complaining
about slow response and timeout errors when accessing some of the web based applications.
What is the most likely reason for this issue?

A.
The company data center and the CSP do not have Layer 2 extension

B.
The company data center and the CSP do not have Layer 3 connectivity

C.
One or more web server dependencies were not moved together to the CSP

D.
Users are not in the same Layer 2 domain as the CSP
