AWS Certification Exam ACTUAL
QUESTIONS AND CORRECT ANSWERS
Cloud Computing - CORRECT ANSWERS Remote virtual pool of on-
demand shared resources offering compute, storage, database, and Network
services that can be rapidly deployed at scale.
Virtualization - CORRECT ANSWERS Allows the possibility of having
multiple virtual machines each running on separate operating systems and
applications, installed on 1 physical server.
Hypervisor - CORRECT ANSWERS Is a piece of software used to create
the virtualized environment allowing for multiple VMS to be installed on the
same host.
What are the benefits of Cloud Computing? (7 Total) - CORRECT ANSWERS
-Reduced capital expenditure
-Less hardware required
-Reduced operating costs
-Less space, power, and cooling (air conditioning)
-Smaller footprint
-Optimization of resources
-Handled by Cloud vendor & consumer
What are the three cloud deployment models? - CORRECT ANSWERS
Public, Private, and Hybrid
Public - Cloud Deployment Model - CORRECT ANSWERS A vendor
makes available the use of shared infrastructure:
-Storage
,-Network
-Database
-Compute
-Consumers can specifically choose the geographic region in which it resides to
aid with data access latency based on where the end users are located.
-However - they will never see (physically) where their data sits.
Private - Cloud Deployment Model - CORRECT ANSWERS The cloud
can only be accessed, hosted, and managed by the individual. company using it.
-Direct control of all data.
-To maintain for tight security reasons
-Hardware is held on-premise - wherever that company is located.
-More capital expenditure is required to host the datacenter
-As well as day-to-day operations needed to maintain equipment.
-Cooling
-Maintenance
-Space
Hybrid - Cloud Deployment Model - CORRECT ANSWERS -Both
public + private
-Can be used for seasonal burst traffic
-Or for Disaster Recovery
-Usually for short-term configurations and can often be used for transitional
states for enterprises.
On-Demand Resourcing - CORRECT ANSWERS -When you want to
provision a resource within the cloud, it's almost immediately available to
allocate where/when you need it.
-No waiting for cables to be ordered, installed, or configured
, Scalability - CORRECT ANSWERS Cloud computing offers you the
ability to rapidly scale your environments/ resources to move up/down or in/out.
Scaling up/down alters the power/performance of the virtual machines
For example) CPU/Memory Power
Scaling in/out is adding/removing virtual machines in resources.
Utility Based Metering - CORRECT ANSWERS Only pay for what you
use.
-2 hours of running instance = 2 hours worth of resources
-This data gets replicated as well in different regions for backup/storage.
Why are cloud vendors more secure than (physical) data centers? (2 main
reasons) - CORRECT ANSWERS -Must comply to global compliance
programs across multiple industries
-Shared responsibility model - holds everyone accountable.
What are the three cloud service models? - CORRECT ANSWERS Saas
(Software as a Service), Paas (Platform as a Service), and Iaas (Infrastructure as
Service).
Saas - CORRECT ANSWERS Allows for the delivery and application
that can be widely distributed and accessed.
-For example - Gmail
-Fully managed/accessed over the internet.
-No requirements to install any software on your local device.
-Usually very simple in design focusing on ease - to appeal to a wider audience.
