Question 7

A company runs its customer relationship management (CRM) system using a cloud provider's SaaS offering. They also use virtual machines (IaaS) from the same provider to host a legacy application. In this scenario, who is responsible for patching the operating system of the virtual machines?

Accepted Answer

The customer is responsible for patching the operating system of the virtual machines.. In an IaaS model, the cloud provider is responsible for the security of the physical infrastructure, hypervisor, and network, but the customer retains responsibility for the guest operating system and applications. Since the virtual machines are IaaS resources, the customer must manage OS patches, updates, and configuration. This follows the shared responsibility model, where the customer is accountable for anything they configure or deploy within the virtual machine.

Answer

The cloud provider is fully responsible for patching all components.

Answer

The cloud provider patches the OS for all services equally.

Answer

No patching is needed because the cloud handles everything.

Question 10

A growing company with 120 users currently holds Microsoft 365 Business Basic licenses.

What is the most cost-effective way to add these capabilities?

Accepted Answer

Purchase add-on subscriptions for Microsoft Intune Plan 1 and Microsoft Defender for Office 365 Plan 1.

Accepted Answer

Software as a Service (SaaS). This scenario describes Software as a Service (SaaS) because the provider delivers fully functional applications—such as email, calendar, and document editing—over the web, with no local installation required. The provider handles all maintenance, updates, and security, which is the defining characteristic of SaaS.

Microsoft Purview Data Loss Prevention (DLP). Microsoft Purview Data Loss Prevention (DLP) is the correct solution because it is specifically designed to detect sensitive information—such as patient health information (PHI) with diagnosis codes—in emails and automatically block external transmission while sending a notification to the sender.

Question 14

A company uses Microsoft 365 (a SaaS offering). A security incident occurs where an employee's account is compromised because the employee reused their corporate password on a personal website. According to the shared responsibility model, who is primarily responsible for this security failure?

Accepted Answer

The customer (the company using Microsoft 365). In the Microsoft 365 shared responsibility model, the customer is responsible for securing user identities, including password hygiene and multi-factor authentication (MFA). Since the employee reused their corporate password on a personal website, this is a customer-side identity management failure, not a platform vulnerability. Microsoft secures the SaaS infrastructure, but customer-managed credentials fall under the customer's responsibility.

Answer

Microsoft, because they provide the SaaS platform

Answer

Both Microsoft and the customer share equal responsibility

Answer

It depends on the contract terms with Microsoft

Question 15

A company uses a cloud service that provides virtual machines. The company manages the operating system, middleware, and applications, while the cloud provider manages the physical hardware, networking, and data center security. Which cloud service model does this represent?

Accepted Answer

Infrastructure as a Service (IaaS). This scenario describes Infrastructure as a Service (IaaS) because the customer manages the operating system, middleware, and applications, while the cloud provider is responsible for the physical hardware, networking, and data center security. In IaaS, the provider delivers virtualized computing resources over the internet, and the customer retains control over the guest OS, storage, and deployed applications, which matches the division of responsibilities given.
