1. The cost of a cloud computing deployment is roughly estimated to be ___________
a) CostCLOUD = Σ(UnitCostCLOUD / (Revenue – CostCLOUD))
b) CostCLOUD = Σ(UnitCostCLOUD x (Revenue + CostCLOUD))
c) CostCLOUD = Σ(UnitCostCLOUD x (Revenue – CostCLOUD))
d) all of the mentioned
Explanation: Unit cost is usually defined as the cost of a machine instance per hour or another resource.
2. Point out the correct statement.
a) Cloud resource pricing doesn’t always scale linearly based on performance
b) Depending upon the service model type, other resources add additional unit costs
c) Typical efficiency in data centers are between 10 and 55 percent
d) All of the mentioned
Explanation: Different cloud providers charge different amounts for these resources, some resources are free for one provider and charged for another, and there are almost always variable charges based on resource sizing.
3. The costs associated with resources in the cloud computing model _______ can be unbundled to a greater extent than the costs associated with CostDATACENTER.
a) CLOUD
b) CostCLOUD
c) CCLOUD
d) All of the mentioned
Explanation: The CostDATACENTER consists of the summation of the cost of each of the individual systems with all the associated resources.
4. Security methods such as private encryption, VLANs and firewalls comes under __________ subject area
a) CostDATACENTER = 1nΣ(UnitCostDATACENTER / (Revenue –(CostDATACENTER/Utilization))SYSTEMn
b) CostDATACENTER = 1nΣ(UnitCostDATACENTER x (Revenue –(CostDATACENTER/Utilization))SYSTEMn
c) CostDATACENTER = 1nΣ(UnitCostDATACENTER x (Revenue +(CostDATACENTER/Utilization))SYSTEMn
d) All of the mentioned
Explanation: Sum includes terms for System 1, System 2, System 3, and so on.
5. Point out the wrong statement.
a) Data center operates under average loads
b) Private cloud doesn’t pooling of resources that a cloud computing provider can achieve
c) Private cloud doesn’t employ the same level of virtualization
d) None of the mentioned
Explanation: Capacity of the datacenter is fixed by the assets it has.
6. For a server with a four-year lifetime, you would therefore need to include an overhead roughly equal to ___ percent of the system’s acquisition cost.
a) 10
b) 20
c) 25
d) All of the mentioned
Explanation: The costs of a system in a datacenter must also include the overhead associated with power, cooling, and the physical plant.
7. The overhead associated with ____ staff is a major cost.
a) Data Center
b) IT
c) Non IT
d) all of the mentioned
Explanation: It is not uncommon for the burden cost of a system in a datacenter to be 150 percent of the cost of the system itself.
8. Moving expenses onto the _____ side of a budget allows an organization to transfer risk to their cloud computing provider.
a) Dex
b) OpEx
c) Pex
d) All of the mentioned
Explanation: The conversion of real assets to virtual ones provides a measure of protection against too much or too little infrastructure.
9. ________ is surely an impediment to established businesses starting new enterprises.
a) Proposition
b) Capitalization
c) Globalization
d) none of the mentioned
Explanation: Capitalization may be the single largest reason that new businesses fail.
10. Cloud computing is also a good option when the cost of infrastructure and management is ______
a) low
b) high
c) moderate
d) none of the mentioned
Explanation: This is often the case with legacy applications and systems where maintaining the system capabilities is a significant cost.
