SC-100 Practice Test 8 — 10 Questions

Question 1

A company has a hybrid identity deployment using Azure AD Connect. They want to ensure that if a user's on-premises account is disabled, the corresponding Azure AD account is also disabled within 30 minutes. Which setting should they configure?

Accepted Answer

Configure the synchronization interval for directory changes. Option B is correct because Azure AD Connect's default synchronization cycle for directory changes is 30 minutes. By configuring the synchronization interval (via the Azure AD Connect scheduler or PowerShell), you can ensure that disabled on-premises accounts are reflected in Azure AD within that timeframe. This setting directly controls how frequently Azure AD Connect processes and synchronizes changes from the on-premises Active Directory to Azure AD.

Answer

Enable password hash synchronization

Answer

Install Azure AD Application Proxy

Answer

Enable password writeback

Question 2

Which TWO of the following are valid methods to secure traffic between on-premises and Azure?

Accepted Answer

ExpressRoute with MACsec. ExpressRoute with MACsec provides encryption at Layer 2 using the IEEE 802.1AE standard, securing traffic between on-premises and Azure over a private connection without traversing the public internet. Site-to-Site VPN uses IPsec (IKEv1/IKEv2) to encrypt traffic over the public internet, establishing a secure tunnel between the on-premises VPN device and Azure VPN Gateway. Both are valid methods for securing traffic, with ExpressRoute+MACsec offering lower latency and higher throughput for private connectivity.

Answer

Azure Front Door

Answer

Azure Traffic Manager

Answer

Azure CDN

Question 3

An organization uses Microsoft Defender for Cloud to secure their multi-cloud environment, including Azure and AWS. They want to ensure that all AWS EC2 instances are automatically onboarded to Defender for Cloud. What should they configure?

Accepted Answer

Set up the AWS connector in Defender for Cloud. Option C is correct because the AWS connector in Microsoft Defender for Cloud is the native integration that enables automatic discovery and onboarding of AWS resources, including EC2 instances, into Defender for Cloud. Once configured, the connector uses AWS IAM roles and APIs to continuously sync EC2 inventory and apply Defender plans (e.g., Defender for Servers) without requiring manual agent installation on each instance.

Answer

Deploy Azure Arc on each EC2 instance

Answer

Use AWS Systems Manager to push Defender workload

Answer

Configure AWS Config rules to report to Defender

Question 4

A financial services company is deploying a three-tier application on Azure. They need to ensure that the web tier can only communicate with the application tier, and the application tier can only communicate with the data tier. All tiers should use private IP addresses. What is the most secure way to implement this?

Accepted Answer

Deploy Azure Firewall and use application rules. Azure Firewall with application rules (FQDN-based) provides the most secure and granular control for east-west traffic between tiers. It can inspect and filter traffic at Layer 7 (application layer) using TLS inspection, ensuring only allowed application protocols (e.g., HTTPS) and specific FQDNs are permitted, while blocking all other traffic. This meets the requirement for private IP communication and enforces a zero-trust model between tiers.

Answer

Use Network Security Groups (NSGs) on each subnet

Answer

Use VNet peering with route tables

Answer

Use Azure Web Application Firewall (WAF)

Question 5

You are a cybersecurity architect for a multinational corporation that is migrating its on-premises workloads to Azure. The environment includes 500 virtual machines across multiple subscriptions, managed through Azure Policy and Azure Blueprints. The security team has reported that some VMs are not receiving the latest security updates despite being configured for automatic updates via the Azure Update Management solution. Additionally, you have noticed that some VMs are missing the Azure Monitor agent, which is required for security monitoring. The company uses Azure Security Center (now Defender for Cloud) with the standard tier enabled. You need to ensure that all VMs are compliant with the company's security baseline, which requires: (1) all VMs must have the Azure Monitor agent installed, (2) all VMs must be enrolled in the Update Management solution, and (3) all VMs must be protected by Microsoft Defender for Cloud. What should you do to enforce compliance and remediate non-compliant VMs?

Accepted Answer

Use Azure Policy with built-in initiatives such as 'Enable Azure Monitor for VMs' and 'Configure machines to automatically install updates' and assign them to all subscriptions. Option A is correct because Azure Policy with built-in initiatives like 'Enable Azure Monitor for VMs' and 'Configure machines to automatically install updates' provides a declarative, scalable, and continuous compliance enforcement mechanism. These initiatives automatically remediate non-compliant VMs by deploying the required agents and configurations across all subscriptions, ensuring all three security baseline requirements are met without manual intervention.

Answer

Create a new Azure Blueprint that includes the required configurations and assign it to all subscriptions

Answer

Use Azure Automation to run scripts that install the agent and enable updates on all VMs

Answer

Configure Microsoft Defender for Cloud to automatically install the Azure Monitor agent and enable updates

Question 6

A company uses Azure Policy to enforce compliance. They want to automatically remediate non-compliant resources by deploying a custom template. Which effect should they use in the policy definition?

Accepted Answer

DeployIfNotExists. The DeployIfNotExists effect is correct because it allows Azure Policy to automatically remediate non-compliant resources by deploying a custom ARM template when the resource is found to be non-compliant. This effect is specifically designed for automatic remediation scenarios, as it triggers a deployment to bring the resource into compliance without manual intervention.

Answer

Audit

Answer

Disabled

Answer

Deny

Question 7

Refer to the exhibit. A network policy is applied in the production namespace. What is the effect on the webapp pod's ability to reach external services?

Accepted Answer

All egress traffic except to kube-dns is denied. Option D is correct because the network policy in the exhibit defines an egress rule that only allows traffic to kube-dns (port 53, UDP) and denies all other egress traffic by default. Since no other egress rules are specified, the webapp pod cannot reach any external services except the cluster's DNS resolver.

Answer

Ingress traffic is blocked

Answer

The pod can only communicate with kube-dns

Answer

The pod can communicate with any service

Question 8

Which TWO of the following are true about Azure DDoS Protection?

Accepted Answer

It can be used to protect against application-layer attacks when combined with WAF. Option C is correct because Azure DDoS Protection operates at Layers 3 and 4 of the OSI model, but when combined with Azure Application Gateway WAF (Web Application Firewall), it can also mitigate application-layer (Layer 7) attacks such as SQL injection or cross-site scripting. The WAF inspects HTTP/HTTPS traffic and blocks malicious payloads, while Azure DDoS Protection handles volumetric attacks, providing a layered defense.

Answer

It automatically blocks all traffic during an attack

Answer

It protects VMs from internal traffic attacks

Answer

It provides a monthly allowance of attacks

Question 9

A company uses Azure Kubernetes Service (AKS) with Azure Active Directory (Azure AD) integration. They want to restrict developers to only be able to create and manage pods and services, but not modify cluster-level resources like nodes or namespaces. What should they configure?

Accepted Answer

Create a custom ClusterRole with rules for pods and services, then bind it to the developer group with a ClusterRoleBinding. Option B is correct because Kubernetes RBAC allows fine-grained authorization. A custom ClusterRole can define rules for pods and services (core API group resources), and a ClusterRoleBinding binds it to the developer group across all namespaces. This grants the required permissions without allowing modifications to cluster-level resources like nodes or namespaces, which are not included in the custom role's rules.

Answer

Assign the cluster-admin ClusterRole to the developers

Answer

Create a RoleBinding in each namespace for developers

Answer

Use Azure RBAC to grant Contributor role on the AKS cluster

Question 10

A company is designing an application architecture using Azure Kubernetes Service (AKS) and Azure Cosmos DB. The application requires that secrets (database connection strings) be injected into pods securely without storing them in the container image. The solution must minimize management overhead. What is the recommended approach?

Accepted Answer

Use Azure Key Vault Provider for Secrets Store CSI Driver to mount secrets as volumes in pods.. Option B is correct because the Azure Key Vault Provider for Secrets Store CSI Driver integrates directly with AKS to securely inject secrets from Azure Key Vault into pods as mounted volumes or environment variables, without storing them in container images or Kubernetes objects. This approach minimizes management overhead by leveraging Azure-managed Key Vault for secret lifecycle management and avoids the operational burden of manually managing Kubernetes Secrets.

Answer

Store secrets in a Kubernetes ConfigMap and reference them in the deployment YAML.

Answer

Define secrets in a Kubernetes Secret object and reference them in the pod spec.

Answer

Hardcode the connection string in an environment variable in the deployment manifest.
