MICROSOFT CERTIFIED AZURE FUNDAMENTALS
ALL FINAL EXAMS QUESTIONS AND ANSWERS
SURE A+
✔✔Compare / Contrast CapEx(Capital Expenditure) vs. OpEx(Operational Expenditure)
- ✔✔•*Capital Expenditure*: the spending of money on physical infrastructure up front,
and then deducting that expense from your tax bill over time. CapEx is an upfront cost,
which has a value that reduces over time.
•*Operational Expenditure*: spending money on services or products now and being
billed for them now. You can deduct this expense from your tax bill in the same year.
There's no upfront cost. You pay for a service or product as you use it.
✔✔What is the primary benefit of CapEx? - ✔✔Fixed Costs and a predictable expense
for your budget! Companies on a tight budget will lean here.
✔✔What is the primary benefit of OpEx? - ✔✔Grows if demand is increased and shrinks
accordingly. For new companies / startups this will make lots of sense.
✔✔What is Cloud agility? - ✔✔Cloud agility is the ability to rapidly change an IT
infrastructure to adapt to the evolving needs of the business. For e.g. if your service
peaks one month, you can scale to demand and pay a larger bill for the month. If the
following month the demand drops, you can reduce the used resources and be charged
,less. This agility lets you manage your costs dynamically, optimizing spending as
requirements change.
✔✔Describe the Public Cloud - ✔✔Microsoft Azure is a public cloud provider. There is
no local hardware to manage or keep up-to-date - everything runs on your cloud
provider's hardware. In some cases, you can save additional costs by sharing
computing resources with other cloud users.
✔✔Give one example of where you would use a public cloud solution - ✔✔Deploy a
website or blog. The web-server is handled by the cloud provider. You only worry about
managing the site itself.
✔✔Give three disadvantages to using a public cloud model. - ✔✔•Security
Requirements
•Government Policies
•Business requirements for a legacy software / application.
✔✔Describe the Private Cloud - ✔✔In a private cloud, you create a cloud environment
in your own datacenter and provide self-service access to compute resources to users
in your organization (You take the place of Microsoft Azure).
✔✔Give one example of where you would use a private cloud solution - ✔✔An
organization has data that cannot be put in the public cloud, perhaps for legal reasons.
An e.g. may be where government policy requires specific data to be kept in-country or
privately.
✔✔Give three disadvantages to using a private cloud model. - ✔✔•Initial CapEx costs
and must purchase the hardware for startup and maintenance
•Owning the equipment limits agility - to scale you must buy, install, and setup new
hardware
•Private clouds require IT skills and expertise.
✔✔Describe the Hybrid Cloud - ✔✔Combine public and private cloud(on premises data-
center). Simple as that.
✔✔What can be a primary disadvantage of the Hybrid Cloud? - ✔✔Humongous
expenses. Running both cloud + on premises is typically very costly! (It might be
necessary in a scenario with legacy Line-of-Business software)
✔✔Describe Infrastructure-as-a-Service (IaaS) - ✔✔You have complete control over the
hardware that runs your application (Servers and virtual machines (VMs), storage,
networks, and OSes). Instead of buying hardware, with IaaS, you rent it. It's an instant
computing infrastructure, provisioned and managed over the internet.
, ✔✔Describe Platform-as-a-Service (PaaS) - ✔✔Primarily used to build, test and deploy
applications, and you can perform all of these actions without managing the underlying
infrastructure.
✔✔Describe Software-as-a-service (SaaS) - ✔✔Software is centrally hosted and
managed for the end customer. It is usually based on an architecture where one version
of the application is used for all customers, and licensed through a monthly or annual
subscription. Office 365, Skype, and Dynamics CRM Online are perfect examples of
SaaS software.
✔✔With regards, to the burden upon the customer, which of the following provides the
least burden?
a). IaaS
b). PaaS
c). SaaS - ✔✔ANSWER: c). *SaaS* On the other extremity, IaaS provides the greatest
burden to the customer, with PaaS balancing between SaaS & IaaS.
✔✔List some core examples of Compute Services in Azure. - ✔✔•Azure VMs
•Azure VM Scale Sets
•Azure Kubernetes Service
•Azure Service Fabric
•Azure Batch
•Azure Container Instances
•Azure Functions
✔✔Give a summary of the function of Azure Kubernetes Service - ✔✔Used to
manage(orchestrate) clusters of VMs that run containerized services (e.g. Docker).
✔✔Describe the Azure Service Fabric - ✔✔Basically a wide range of Azure systems
that run in the cloud or on-premises.
✔✔What is an Azure Container Instance / is it used for? - ✔✔It is used to run
applications in Azure without the need of a VM, or provisioned server.
✔✔Describe an Azure function in as few words as possible., then give an example. -
✔✔An event-driven, serverless compute service (e.g. confirmation of a successful login
to a bank account).
✔✔List some of the core products that make up Azure Networking. - ✔✔•Azure Network
Watcher
•Azure Express Route
•Azure Traffic Manager
•Azure Content Delivery Network
•Azure Application Gateway
•Azure Virtual Network
