C.    Scalability

                       D.    Security


                          C. Scalability embodies the ability to grow in a controlled manner,
                     as in increasing computing infrastructure as business needs demand.
                          A, B, and D are incorrect. A reduction in time to market for new

                     products and services gives a company a competitive edge, but it does
                     not  apply  to  the  scenario.  Vendor  lock-in  ties  customers  to  vendor-
                     specific solutions, which is not the case here. Security does apply to
                     cloud  computing,  but  it  does  not  relate  to  this  scenario,  where  new
                     hardware and software must be procured.


               14.   For a software development firm, which of the following cloud

                     benefits is realized with PaaS?
                       A.    Time to market

                       B.    Vendor lock-in
                       C.    Scalability

                       D.    Security


                          A. PaaS allows developers to quickly create and test applications.
                     Getting  your  product  to  market  before  your  competitors  can  give  a
                     competitive edge.

                          B, C, and D are incorrect. Vendor lock-in ties customers to vendor-
                     specific  solutions,  but  this  is  not  a  benefit  of  PaaS.  Scalability
                     embodies  the  ability  to  grow  in  a  controlled  manner,  but  it  is  not  a
                     distinguishing  feature  of  PaaS  as  compared  to  other  types  of  cloud
                     offerings. Security does apply to cloud computing but not specifically

                     to PaaS.


               15.   How does cloud computing affect a cloud customer’s cost structure?
                       A.    OPEX becomes CAPEX.

                       B.    CAPEX becomes OPEX.

                       C.    CAPEX increases.
                       D.    OPEX decreases.


                            B.  Instead  of  spending  capital  to  acquire  computing  hardware,
                     software,  and  licenses,  cloud  customers  can  essentially  rent  the  IT
                     services  they  need  as  they  need  them;  thus,  capital  expenditures
