Microsoft Certified Azure Fundamentals
Exam (AZ-900) Questions With Correct
Answers
What are some computing services offered by a Cloud Provider? -
| | | | | | | | | | |
CORRECT ANSWER✔✔-•*Compute power* - e.g. Servers or web
| | | | | | | |
applications
•*Storage* - e.g. Files and Databases | | | | |
•*Networking* - e.g. secure connections between the cloud provider
| | | | | | | | |
and on-premises.
|
•*Analytics* - e.g. visual telemetry and performance data

Jim the systems admin at a fictitious company is an absolute control
| | | | | | | | | | | |
freak! From the list below, choose the most appropriate cloud solution
| | | | | | | | | | |
for him:
|
a). Virtual Machines
| |
b). Containers
|
c). Serverless compute - CORRECT ANSWER✔✔-ANSWER: a). *Virtual
| | | | | | | |
Machines.* Because he will emulate a physical system, Jim can do
| | | | | | | | | | |
whatever he likes (e.g. install software, configure updates etc.)
| | | | | | | |
,Give the simplest definition of a container. - CORRECT ANSWER✔✔-A
| | | | | | | | | |
container is similar to a VM but it doesn't need a guest operating
| | | | | | | | | | | | |
system.
What is Serverless Computing? - CORRECT ANSWER✔✔-Serverless
| | | | | | |
computing lets you run application code(e.g. functions) without
| | | | | | | |
creating, configuring, or maintaining a server. When compared to VMs
| | | | | | | | | |
and Containers, it is the lightest and fastest deployment method.

Rob is new to cloud computing and is confused by the terms: "Vertical
| | | | | | | | | | | | |
Scaling" and "Horizontal" scaling. Give him a brief rundown on the
| | | | | | | | | | |
differences between the two! - CORRECT ANSWER✔✔-*Vertical
| | | | | | |
scaling*: aka "scaling up", is the process of adding resources to increase
| | | | | | | | | | | |
the power of an existing server. Some examples of vertical scaling are:
| | | | | | | | | | | |
*adding more CPUs, or adding more memory*.
| | | | | |
*Horizontal scaling*: aka "scaling out", is the process of adding more
| | | | | | | | | | |
servers that function together as one unit. For example, *you have more
| | | | | | | | | | |
than one server processing incoming requests*
| | | | | |
Define: Scalability as it relates to cloud computing - CORRECT
| | | | | | | | | |
ANSWER✔✔-You can increase or decrease the resources and services | | | | | | | | |
used based upon the needs of your organization.
| | | | | | |
,Define: Elasticity as it relates to cloud computing - CORRECT
| | | | | | | | | |
ANSWER✔✔-As your workload changes due to a spike or drop in | | | | | | | | | | |
demand, a cloud computing system can compensate by automatically
| | | | | | | | |
adding or removing resources. (e.g. a web-site during Black Friday Sale)
| | | | | | | | | |
Define: redundancy as it relates to cloud computing - CORRECT
| | | | | | | | | |
ANSWER✔✔-If one component fails, another is available to take its | | | | | | | | | |
place and its workload.
| | |
Define: fault-tolerance as it relates to cloud computing - CORRECT
| | | | | | | | | |
ANSWER✔✔-Customers and end-users are not impacted when a | | | | | | | |
disaster occurs. |
Misha the cloud computing class nerd wants to engage you in a
| | | | | | | | | | | |
discussion on Economies of Scale. Start the conversation off with an
| | | | | | | | | | |
adequate definition and an example. - CORRECT ANSWER✔✔-
| | | | | | |
Economies of scale is *the ability to do things more efficiently or at a
| | | | | | | | | | | | | |
lower-cost per unit when operating at a larger scale.* In other words,
| | | | | | | | | | | |
more money is saved, when production rates are higher. Users also pay
| | | | | | | | | | | |
less for power consumption, cooling and network connectivity than they
| | | | | | | | |
|would with on-premises infrastructure.
| | |
Compare / Contrast CapEx(Capital Expenditure) vs. OpEx(Operational
| | | | | | |
Expenditure) - CORRECT ANSWER✔✔-•*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? - CORRECT ANSWER✔✔-Fixed
| | | | | | | | | |
Costs and a predictable expense for your budget! Companies on a tight
| | | | | | | | | | | |
budget will lean here. | | |
What is the primary benefit of OpEx? - CORRECT ANSWER✔✔-Grows if
| | | | | | | | | | |
demand is increased and shrinks accordingly. For new companies /
| | | | | | | | | |
startups this will make lots of sense.
| | | | | |
What is Cloud agility? - CORRECT ANSWER✔✔-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 - CORRECT ANSWER✔✔-Microsoft Azure is a
| | | | | | | | | |
public cloud provider. There is no local hardware to manage or keep up-
