C838 – Opening Exam Questions with 100%
Correct Answers.
BIA (Business Impact Analysis)
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
the organization only pays for what it uses
Rapid Elasticity
excess capacity available to be apportioned to cloud customers
Cloud bursting
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
ROI (Return on Investment)
term related to cost-benefit measures; used to describe a profitability ratio; calculated by dividing
net profits by net assets
Elasticity
customers can contract cloud providers to use virtualization to flexibly allocate only the needed
usage 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
,allow a user to seamlessly use the service without frequently interacting with the cloud service
provider
Scalability
increasing/reducing services can be easily, quickly, and cost-effectively accomplished
IaaS (Infrastructure as a Service)
most basic service; allows customer to install all software and OSs on hardware housed and
connected by the cloud vendor; can be considered a warm site for BC/DR purposes; optimal for
orgs wanting control over the security of their data and limited cloud vendor assistance (BC/DR
or archiving); least expensive option; customer retain IT staffing
When to use IaaS
website or application hosting; virtual data centers; data analysis
PaaS (Platform as a Service)
includes services from IaaS and OSs (offers a selection for customers to use, Windows, Linux,
Mac, etc.); vendor is responsible for patching, administering, and updating the OS; customer can
install any software; useful for customers involved in software development (they can test on
multiple OS platforms); includes cloud-based database engines and services "big data" style
services (data warehousing and data mining); provider offers access to back-end
engine/functionality, while customer can create/install apps/APIs to access the backend; uses
structured/unstructured storage
When to use PaaS
reduce development time; support for different programming languages; easy collaboration for
remote/distributed teams; high development capabilities w/o additional staff
Unstructured Data Types
qualitative data; natural-language text; incorporate media (audio, video, images); contains JSON,
XML, binary objects (images encoded as text strings); important for data analytic strategies;
noSQL
, Structured Data Types
quantitative data; organized and decipherable by machine learning algorithms; SQL (relational)
can be used to quickly input, search, and manipulate data; used by machine learning algorithms
SaaS (Software as a Service)
includes everything from IaaS and PaaS with the addition of software programs; vendor is
responsible for administering, patching, and updating everything, also takes care of all
infrastructure, compute, and storage needs as well as providing OSs and application; customer is
only involved in uploading and processing data on a full production environment; application is a
shared responsibility of all parties
When to use SaaS
(Personal) email services (gmail), cloud storage services (Dropbox), cloud-based file
management (Google Docs); (Business) gmail, collaboration tools (Trello), CRM (Salfesforce),
ERP
Public Cloud
resources are owned and operated by a vendor and sold, leased, or rented to anyone; multitenant
environments; multiple customers will share resources; EX: customer might be using a AM that
resides on the same hardware that hosts another VM as their competitor, but they do not know
the entities using the same resources; Rackspace, Microsoft's Azure, and AWS (Amazon Web
Services)
Private Cloud
resources dedicated to a single customer; might be owned and maintained by the entity that is the
sole customer (org might own and operate a data center that serves as the cloud environment for
the org's users); might be a set of resources (racks, blades, software packages) owned by the
single customer but located and maintained at provider's data center; provider might offer
physical security, admin services, and utilities (power, Internet) for customers (referred to as co-
lo (co-located) environment)
Community Cloud
