Scenario 1: When you are implementing a Software as a Service (SaaS) solution, you are
responsible for configuring high availability.
Instructions: Review the underlined text. If it makes the statement correct, select "No change is
needed". If the statement is incorrect, select the answer choice that makes the statement
correct.
Question: When you are implementing a Software as a Service (SaaS) solution, you are
responsible for:
A. No change is needed. (i.e., configuring high availability)
B. defining scalability rules
C. installing the SaaS solution
D. configuring the SaaS solution
Correct Answer: D. configuring the SaaS solution
Rationale:
• In a Software as a Service (SaaS) model, the cloud provider (or the SaaS vendor) is
responsible for managing the entire application stack, including the underlying
infrastructure, operating systems, and even the application's high availability.
• Your primary responsibility as a consumer of SaaS is typically limited to configuring the
application to meet your specific business needs (e.g., setting up users, permissions,
specific features).
• You are generally not responsible for defining scalability rules, installing the solution (it's
ready to use via a browser or API), or configuring its high availability as these are
managed by the provider.
,Scenario 2: You have an on-premises network that contains several servers. You plan to migrate
all the servers to Azure. You need to recommend a solution to ensure that some of the servers
are available if a single Azure data center goes offline for an extended period.
Question: What should you include in the recommendation to ensure server availability during
a data center outage?
A. fault tolerance
B. elasticity
C. scalability
D. low latency
Correct Answer: A. fault tolerance
Rationale:
• To ensure servers are available if a single Azure data center goes offline, you need to
implement fault tolerance. This involves designing your solution to withstand failures,
typically by deploying resources across multiple Availability Zones within a region or
across different Azure regions. This ensures that if one data center experiences an
outage, your application and data remain accessible from another.
• Elasticity refers to the ability to automatically grow or shrink resources based on
demand, which is related to performance and cost, not disaster recovery from a data
center outage.
• Scalability is the ability to handle an increasing amount of work or to be enlarged, and
while important, it doesn't directly address the problem of a data center outage in the
same way fault tolerance does.
• Low latency refers to minimizing delays in data transmission, which is about
performance and responsiveness, not high availability during an outage.
Scenario 3: An organization that hosts its infrastructure in a private cloud can decommission its
data center.
Instructions: Review the underlined text. If it makes the statement correct, select "No change is
needed". If the statement is incorrect, select the answer choice that makes the statement
correct.
,Question: An organization that hosts its infrastructure can decommission its data center if it
moves its infrastructure:
A. No change is needed. (i.e., in a private cloud)
B. in a hybrid cloud
C. in the public cloud
D. on a Hyper-V host
Correct Answer: C. in the public cloud
Rationale:
• A private cloud by definition means the infrastructure is hosted within an organization's
own data center or a dedicated environment. Therefore, if an organization is still using a
private cloud, it cannot decommission its data center because the data center is where
the private cloud resides.
• To fully decommission an on-premises data center, an organization must migrate all its
infrastructure to the public cloud, where a third-party provider manages all the physical
hardware and infrastructure.
• A hybrid cloud combines on-premises and public cloud resources, meaning the on-
premises data center would still be necessary for the on-premises component.
• Hosting "on a Hyper-V host" implies an on-premises virtualization solution, which also
requires a data center.
Scenario 4: What are two characteristics of the public cloud? Each correct answer presents a
complete solution.
Question: What are two characteristics of the public cloud? (Choose two)
A. dedicated hardware
B. unsecured connections
C. limited storage
D. metered pricing
E. self-service management
Correct Answers: D. metered pricing AND E. self-service management
, Rationale:
• D. Metered pricing: In the public cloud, you typically pay only for the resources you
consume, often on a pay-as-you-go or metered basis. This is a fundamental aspect of
public cloud cost models.
• E. Self-service management: Public cloud providers offer portals and APIs that allow
users to provision, manage, and de-provision their cloud resources independently,
without requiring direct interaction with the provider's staff.
• A. Dedicated hardware: Public cloud typically uses shared infrastructure (multi-
tenancy), not dedicated hardware for each customer, although dedicated host options
exist, they are not a universal characteristic.
• B. Unsecured connections: Public cloud providers invest heavily in security, and
connections are typically secured using various encryption and networking protocols.
The responsibility for securing data within the cloud is shared, but connections are not
inherently unsecured.
• C. Limited storage: Public cloud storage services offer massive scalability, effectively
providing virtually unlimited storage capacity, not limited storage.
Scenario 5: When planning to migrate a public website to Azure, you must plan to pay monthly
usage costs.
Instructions: Review the underlined text. If it makes the statement correct, select "No change is
needed". If the statement is incorrect, select the answer choice that makes the statement
correct.
Question: When planning to migrate a public website to Azure, you must plan to:
A. No change is needed. (i.e., pay monthly usage costs)
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. No change is needed
