SECTION A — FOUNDATIONS
Question 1
A regional health clinic is planning to move its legacy patient appointment system to the cloud.
They want to avoid managing underlying operating systems and database patching, focusing only
on developing the application code. Which cloud deployment model best fits this requirement?
A) Infrastructure-as-a-Service (IaaS)
B) Platform-as-a-Service (PaaS)
C) Software-as-a-Service (SaaS)
D) On-premises infrastructure
,Answer: B
Rationale:
a) PaaS provides a framework for developers to build applications without managing the
underlying OS, storage, or infrastructure.
b) The key feature is the clinic wanting to focus only on application code while the provider
handles OS and database patching.
c) SaaS (C) is incorrect because SaaS provides a completed software product, not an environment
for custom application development.
d)
Examiner Pearl:
In PaaS, the customer manages the application and data, while the cloud provider manages
everything below the application layer. [Microsoft Learn Cloud Concepts 2025]
Question 2
A large hospital network uses Microsoft 365 for staff communication but maintains a proprietary,
highly sensitive patient database on servers physically located within the hospital premises due to
strict local regulatory requirements. Which type of cloud model does this architecture represent?
A) Public Cloud
B) Private Cloud
C) Hybrid Cloud
D) Multi-Cloud
Answer: C
Rationale:
a) A hybrid cloud combines on-premises infrastructure (private cloud) with public cloud services
(like Microsoft 365), allowing data and applications to be shared between them.
b) The presence of both Microsoft 365 (public) and local on-premises servers (private) working
together seals the answer.
c) Private cloud (B) is incorrect because it ignores the use of the public Microsoft 365
environment.
d)
Examiner Pearl:
,Hybrid cloud is the most common transition state for enterprise healthcare, offering regulatory
compliance for legacy data while enabling modern cloud collaboration. [Microsoft Cloud
Architecture 2025]
Question 3
An NHS trust is deploying Microsoft 365. The Chief Information Security Officer (CISO) is
reviewing the Shared Responsibility Model. Which of the following responsibilities will ALWAYS
remain with the NHS trust, regardless of whether they use IaaS, PaaS, or SaaS?
A) Physical network security
B) Operating system patching
C) Information and data classification
D) Hypervisor management
Answer: C
Rationale:
a) In the Shared Responsibility Model, the customer is always responsible for their information and
data, devices, and accounts/identities.
b) Data classification is a core customer responsibility because Microsoft cannot determine the
clinical sensitivity of the trust's specific data.
c) OS patching (B) shifts to Microsoft in PaaS and SaaS, making it variable rather than absolute.
d)
Examiner Pearl:
Memorise the "Always Customer" tier: Data, Endpoints, Account, and Access Management.
[Microsoft Shared Responsibility Model 2025]
Question 4
A general practice is evaluating Microsoft 365 capabilities. They need a service that allows
doctors to co-author clinical guidelines in real-time and acts as a central repository for
departmental files. Which Microsoft 365 service is primarily designed for this?
A) Microsoft Exchange Online
B) Microsoft SharePoint Online
C) Microsoft Stream
D) Microsoft Viva Insights
, Answer: B
Rationale:
a) SharePoint Online is the foundational document management and intranet platform in M365,
enabling secure storage and real-time co-authoring of files.
b) The requirement for a "central repository" for departmental files rather than personal files
points directly to SharePoint over OneDrive.
c) Exchange Online (A) is for email and calendaring, not document co-authoring or departmental
file repositories.
d)
Examiner Pearl:
SharePoint is the backend storage engine for Microsoft Teams channel files, driving enterprise
document management. [M365 Productivity Guide 2025]
Question 5
Dr. Smith wants to store her personal draft notes and conference presentations securely in the
cloud, ensuring she can access them from her tablet at home or her workstation at the clinic.
Which service is best suited for this individual storage need?
A) Microsoft OneDrive
B) Microsoft SharePoint
C) Microsoft Lists
D) Microsoft Planner
Answer: A
Rationale:
a) OneDrive is the Microsoft cloud service that connects you to all your individual files, allowing
storage, protection, and cross-device access.
b) The scenario specifically highlights "personal draft notes" and "individual storage,"
distinguishing it from team-based storage.
c) SharePoint (B) is incorrect as it is designed for shared, team-level intranet and document
management, not personal user directories.
d)
