What are two characteristics of the public cloud? Each correct answer presents a complete
solution.
A. Dedicated hardware
B. Unsecured connections
C. Limited storage
D. Metered pricing
E. Self-service management - correct answer D,E
Ans:
Advantages of public clouds:
Lower costs-no need to purchase hardware or software, and you pay only for the service you
use.
No maintenance-your service provider provides the maintenance.
Near-unlimited scalability-on-demand resources are available to meet your business needs.
High reliability-a vast network of servers ensures against failure.
This question requires that you evaluate the UPPER-CASED text surrounded by *** to
determine if it is correct.
When planning to migrate a public website to Azure, you must plan to *** PAY MONTHLY
USAGE *** costs.
A. No change is needed
,B. Deploy a VPN
C. Pay to transfer all the website data to Azure
D. Reduce the number of connections to the website - correct answer A
Ans:
Azure doesn't directly bill based on the resource cost. Charges for a resource are calculated by
using one or more meters. Meters are used to track a resource's usage throughout its lifetime.
These meters are then used to calculate the bill.
For example, when you create a single Azure resource, like a virtual machine, it has one or more
meter instances created. Meters are used to track the usage of the resource over time. Each
meter emits usage records that are used by Azure to calculate the bill.
For example, a single virtual machine (VM) created in Azure may have the following meters
created to track its usage:
Compute Hours, IP Address Hours, Data Transfer In, Data Transfer Out, Standard Managed Disk,
Standard Managed Disk Operations, Standard IO-Disk, Standard IO-Block Blob Read, Standard
IO-Block Blob Write, Standard IO-Block Blob Delete
Your company plans to migrate all its data and resources to Azure.
The company's migration plan states that only platform as a service (PaaS) solutions must be
used in Azure.
You need to deploy an Azure environment that supports the planned migration.
Solution: You create an Azure App Service and Azure SQL databases.
Does this meet the goal?
Yes/No - correct answer Yes
Ans:
Platform as a service (PaaS) is a complete development and deployment environment in the
cloud, with resources that enable you to deliver everything from simple cloud-based apps to
,sophisticated, cloud-enabled enterprise applications. You purchase the resources you need
from a cloud service provider on a pay-as-you-go basis and access them over a secure Internet
connection.
Like IaaS, PaaS includes infrastructure-servers, storage and networking-but also middleware,
development tools, business intelligence (BI) services, database management systems and
more. PaaS is designed to support the complete web application lifecycle: building, testing,
deploying, managing and updating.
PaaS allows you to avoid the expense and complexity of buying and managing software
licenses, the underlying application infrastructure and middleware, container orchestrators
such as Kubernetes or the development tools and other resources. You manage the
applications and services you develop and the cloud service provider typically manages
everything else.
Your company hosts an accounting named App1 that is used by all the customers of the
company.
App1 has low usage during the first three weeks of each month and very high usage during the
last week of each month.
Which benefit of Azure Cloud Services supports cost management for this type of usage
pattern?
A. High availability
B. High latency
C. Elasticity
D. Load balancing - correct answer C
Ans:
Elastic computing is the ability to quickly expand or decrease computer processing, memory,
and storage resources to meet changing demands without worrying about capacity planning
and engineering for peak usage. Typically controlled by system monitoring tools, elastic
computing matches the amount of resources allocated to the amount of resources actually
needed without disrupting operations. With cloud elasticity, a company avoids paying for
unused capacity or idle resources and doesn't have to worry about investing in the purchase or
maintenance of additional resources and equipment.
, While security and limited control are concerns to take into account when considering elastic
cloud computing, it has many benefits. Elastic computing is more efficient than your typical IT
infrastructure, is typically automated so it doesn't have to rely on human administrators around
the clock, and offers continuous availability of services by avoiding unnecessary slowdowns or
service interruptions.
You plan to migrate a web application to Azure. The web application is accessed by external
users.
You need to recommend a cloud deployment solution to minimize the amount of
administrative effort used to manage the web application.
What should you include in the recommendation?
A. Software as a Service (SaaS)
B. Platform as a Service (PaaS)
C. Infrastructure as a Service (IaaS)
D. Database as a Service (DaaS) - correct answer B
Ans:
IaaS (Information as a Service). IaaS is the most basic level of cloud-based solutions, which
refers to renting an IT infrastructure as a fully outsourced service. In this category, the cloud
provider lets you rent servers, VMs, storage, network and operating systems on a pay-as-you-
go basis.
Examples: Amazon EC2 and S3, Google Compute Engine, Windows Azure.
PaaS (Platform as a Service). PaaS is the cloud solution where, apart from providing an
infrastructure, cloud providers also issue an on-demand computing environment to develop,
test, run and collaborate with components such as web servers, database management
systems, and software development kits (SDKs) for various programming languages.
Examples: AWS Elastic Beanstalk, Heroku, Windows Azure, Force.com, Google App Engine.
SaaS (Software as a Service). SaaS providers offer fully functional web-based application
softwares tailored to a variety of business needs such as project tracking, web conferencing,
marketing automation or business analytics.
Examples: Google Apps, Microsoft Office 365, Gmail, Yahoo and Facebook.
