MANAGING CLOUD SECURITY | QUESTIONS AND
ANSWERS | GRADE A | 100% CORRECT (VERIFIED
ANSWERS) - WGU
BIA (Business Impact Analysis): .....ANSWER.....an assessment of
the priorities given to each asset and process within the
organization; analysis considers the effect (impact) any hard or
loss might mean to the organization overall; identify critical paths
and single points of failure; determine costs of compliance
(legislative and contractual requirements mandated)
Metered service: .....ANSWER.....the organization only pays for
what it uses
Rapid Elasticity: .....ANSWER.....excess capacity available to be
apportioned to cloud customers
,Page 2 of 66
Cloud bursting: .....ANSWER.....organizations to use hosted cloud
service to augment internal, private data center capabilities with
managed services during times of increase demand; an org can
rent the additional capacity as needed from an external cloud
provider (crisis situation, heavy holiday shopping periods); rapid
scalability allows customer to dictate the volume of resource
Cloud service benefits .....ANSWER.....reduction in personnel cost
(data management); reduction in capital expenditure (metered
service, rapid elasticity, cloud bursting); reduction in operational
costs; transferring some regulatory costs; reduction in costs for
data archival/backup services
ROI (Return on Investment): .....ANSWER.....term related to cost-
benefit measures; used to describe a profitability ratio;
calculated by dividing net profits by net assets
Elasticity: .....ANSWER.....customers can contract cloud providers
to use virtualization to flexibly allocate only the needed usage
,Page 3 of 66
of each resource to the organization, while holding costs while
maintaining profitability; allow users to access their data from
diverse platforms and locations, increasing portability,
accessibility, and availability
Simplicity: .....ANSWER.....allow a user to seamlessly use the
service without frequently interacting with the cloud service
provider
Scalability: .....ANSWER.....increasing/reducing services can be
easily, quickly, and cost-effectively accomplished
IaaS (Infrastructure as a Service) .....ANSWER.....What it is: Cloud
provider gives you raw infrastructure — servers, storage,
networking — but you install and manage the OS, applications,
and everything else.
Think of it as: Renting a fully built apartment building shell —
you bring the furniture, appliances, and decorate it how you
want.
, Page 4 of 66
Examples: Amazon EC2 (AWS) → You get a virtual server, but
you set up the OS and software. Google Compute Engine (GCE)
Microsoft Azure VMs
Best for: Companies that want control and customization, but
don't want to buy/manage physical hardware.
"I build on rented servers." (Control everything)
PaaS (Platform as a Service) .....ANSWER.....What it is: Cloud
provider gives you infrastructure + runtime environment (OS,
middleware, database, dev tools). You just build and run your
applications on top of it.
Think of it as: Renting an apartment that's already furnished and
decorated — you just move in and live. You don't worry about
plumbing, electricity, or furniture.
