When outlining the potential financial savings from having virtualized network services modules, which statement would be a supportable statement to make? Select the best response.
A.
Because the services are virtual, virtual network services modules will take up no rack space and will consume no power.
B.
The savings will depend upon the requirements for each data center but can be as much as
646-985
80 percent on power and 30 units of rack space.
C.
Virtual services modules can support up to a maximum of four virtual contexts, so they can save up to 75 percent of both power and rack space.
D.
Every time a new virtual context is created, the services modules draw 50 percent more power than a single-context operation, so the maximum number of virtual contexts is limited to four per module. With the maximum of four virtual contexts, the total power consumed is 250 percent of a single context operation, which is 150 percent less power than four physical service appliances would draw.
