WGU D320– Questions With Complete Solutions (Pass!)
Cloud Computing Right Ans - where computing services are being
delivered to a customer at a remote location over a network. Can be scalable
like accessing gmail account
NIST Right Ans - National Institute of Standards and Technology. NIST is a
part of the U.S. Department of Commerce
Two primary roles of cloud computing Right Ans - cloud service provider
and customer
Cloud service provider Right Ans - a company that offers cloud computing
services to others. responsible for building and maintaining their services
Cloud service partners Right Ans - offer some product or service that
interacts w primary offerings of a cloud service provider
CASB Right Ans - Cloud Access Security Broker
Cloud access security broker Right Ans - a cloud cybersecurity layer that
focuses on visibility, compliance, data security, and threat protection. offer
managed identity and access management service
Horizontal scaling Right Ans - adding more servers to the pool
Vertical scaling Right Ans - increasing capacity by upgrading existing
resources to be more powerful
Cloud offers Right Ans - rapid elasticity
Rapid elasticity Right Ans - computing resources can be rapidly
provisioned, increased, or decreased to meet changing user demand
Elasticity Right Ans - allows you to automatically add servers until capacity
is met and removes it when it isn't needed anymore
,Metered service Right Ans - Fee charged by cloud service providers on the
basis of how much of a resource was used. Fees may be based on things like
access time, bandwidth used, bytes uploaded or downloaded, CPU usage, and
other resource usage metrics.
On-demand self-service Right Ans - consumers can obtain computing
capabilities such as server time or network storage as needed automatically
on their own
Broad network access Right Ans - Access to the Cloud is available using a
wide variety of client devices, such as PCs, laptops, tablets, and smartphones.
Multitenancy Right Ans - different customers share/use the same
computing resources. allows provider to oversubscribe their resources.
Preserving isolation Right Ans - even with multitenancy it's important to
keep data, user actions, etc isolated.
resource pooling Right Ans - why multitenancy works. memory and CPU
capacity of the physical enviornment are shared among users and reassigned
as needed. This can cause slow downs and outages if everyone needs
everything all at once.
BIA Right Ans - business impact analysis - a study of the possible impact if
a disruption to the business's vital resources were to occur
include ROI and cost benefit analysis
Cost-benefit analysis Right Ans - lists all the benefits with a decision with
their costs. could be just quantitiative to determine if a decision will be
profitable
Can also have intangible benefits like increase productivity, access to tech, etc
see if it justifys the cost
Hypervisor Right Ans - tricks each guest of VM to think it's running on it's
own device and OS's of their own
type one hypervisor Right Ans - bare metal
,runs on the hardware and hosts other OS's
most common in data centers
Type two hypervisor Right Ans - the host runs on an OS of its own and
hypervisor is a program on it
Hypervisor that operates on the software of the host computer
common for personal computers
VM escape Right Ans - An attack that allows an attacker to access the host
system from within a virtual machine. The primary protection is to keep hosts
and guests up to date with current patches.
VM Sprawl Right Ans - A vulnerability that occurs when an organization
has many unused and abandoned servers. Unmanaged VMs are not kept up to
date with current patches.
ephemeral computing strategy Right Ans - temporary
cam create computing resources like servers and storage spaces and then get
rid of them when you don't need them
VDI Solutions Right Ans - virtual desktop infrastructure
provide virtualization to desktop technology so users can access a desktop
enviornment with their preferred system
application virtualization Right Ans - allows users to access apps on their
systems that are running in a diff environment (application streaming)
block storage Right Ans - breaking files into pieces and writing those pieces
to the fundamental storage areas of the drive. Data is reassembled when
called by the operating system.
used for virtual disk drives and cloud servers
so like partitioning data into drives
object storage Right Ans - each object consists of data, metadata, and a key
cloud provider worries where to place the files after customer uploads
cheaper
used to maintain files
VPC Right Ans - Virtual Private Cloud
, Virtual Private Cloud Right Ans - similar to VLANS
systems in this can easily communicate with eachother and you can create
rules to define traffic inside and to and from others
Database Right Ans - repository of information and backbone of
transactional systems
Managed database service Right Ans - Request database from cloud
provider using platform of choice
Transfer maintenance responsibility to cloud provider
Incurs additional costs
cloud-native database Right Ans - allows use of relational databases, key
value stores, graph database,
high degree of cloud optimization
management burden on provider
requires retooling existing applications
hybrid enviornments Right Ans - add complexity to cloud operations
cloud orchestration Right Ans - creates automated workflows for managing
cloud enviornments
allows admins to quickly and easily create workloads, shift operations, etc
Automates cloud management
IaaC
IaaC Right Ans - manages cloud programmatically
ISO 17789 Right Ans - Cloud Computing Reference Architecture
common terminology framework that assists service providers, cloud
customers, and cloud service partners regarding roles and responsibilities.
