A.    Evaluate other functionally equivalent SaaS offerings.

                       B.    Keep using the on-premises end-user software.
                       C.    Use cloud backup for the end-user software data.

                       D.    Use PaaS instead.


                          A. Cloud providers might have a SaaS offering that has the same

                     functionality of the in-house software in use. This should be explored
                     first.
                          B, C, and D are incorrect. Since cloud evaluation was part of the
                     question, keeping the existing software solution is not the best choice.
                     Cloud  backup  does  not  address  the  issue  of  using  a  cloud  SaaS
                     solution. PaaS is for developers to quickly create and test applications,
                     not end-user productivity software.



               39.   Your company currently has six virtual servers hosted on premises
                     using two clustered physical servers. The two physical servers on
                     which the six virtual servers are running must be replaced. You have
                     been asked to recommend the quickest solution to run the six virtual
                     machines in the cloud instead of on the premises. What should you
                     recommend?

                       A.    Back up the existing virtual servers. Create new cloud virtual
                           servers and restore the data into them.

                       B.    Migrate the existing virtual machines to the cloud.
                       C.    You cannot migrate virtual machines to the cloud.

                       D.    Re-create the six virtual machines in the cloud from scratch.


                          B. Migrating existing virtual machines to the cloud is the quickest
                     solution. Most cloud providers offer this solution.
                          A, C, and D are incorrect. Creating new virtual servers in the cloud

                     and restoring data to them normally takes longer than simply migrating
                     virtual servers to the cloud. Most cloud providers offering IaaS allow
                     cloud customers to migrate virtual machines to the cloud.


               40.   Which of the following is a reason to migrate an application to the
                     cloud?

                       A.    Elasticity.
                       B.    Data encryption.

                       C.    High availability.
