SC-900 Practice Question: Describe the concepts of security, compliance, and identity
This SC-900 practice question tests your understanding of describe the concepts of security, compliance, and identity. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company is deploying a web application on Azure App Service. The security officer states that according to the shared responsibility model, the customer is responsible for managing access to the application and securing the application code. Which of the following responsibilities does Microsoft retain for Azure App Service?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Patching the underlying operating system of the App Service host
For Azure App Service, Microsoft retains responsibility for patching the underlying operating system of the host infrastructure. This is part of the shared responsibility model where the cloud provider manages the host OS and hypervisor, while the customer manages the application code, data, and access configurations.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Configuring network firewall rules for the App Service
Why it's wrong here
Network firewall rules specific to the App Service (like IP restrictions) are configured by the customer as part of application security.
✓
Patching the underlying operating system of the App Service host
Why this is correct
Microsoft is responsible for patching the host OS and underlying infrastructure as part of the PaaS shared responsibility model.

✗
Managing user authentication and authorization
Why it's wrong here
Authentication and authorization (e.g., using Microsoft Entra ID) are managed by the customer.
✗
Applying encryption to the application data at rest
Why it's wrong here
Encryption of data at rest is a customer responsibility, though Azure provides platform-managed encryption options.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse 'patching the underlying OS' with 'patching the application runtime' or 'configuring network security,' mistakenly thinking Microsoft handles all security tasks for PaaS services, when in fact the customer retains significant control over access and data protection.
Detailed technical explanation
How to think about this question
Under the shared responsibility model, Microsoft manages the 'security of the cloud' including the physical hosts, hypervisor, and host OS patching. For Azure App Service, this means Microsoft applies OS-level security updates to the sandboxed worker instances without customer intervention. The customer, however, is responsible for securing their application code, managing network access controls (e.g., via Access Restrictions in the Azure portal), and configuring data encryption at rest using Azure Key Vault or service-side encryption settings.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
