AZ-500 Practice Test 21 — 15 Questions

Question 1

A company has an Azure virtual network with a subnet that hosts a public web application. They want to allow inbound HTTPS traffic (port 443) only from the source IP range 203.0.113.0/24, and block all other inbound traffic. They associate a network security group (NSG) with the subnet. What is the minimum number of inbound security rules required in the NSG to achieve this?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

1. NSGs include default inbound rules that already block all inbound traffic not explicitly allowed. By adding a single inbound rule to allow HTTPS (port 443) from the source IP range 203.0.113.0/24, all other inbound traffic is implicitly denied by the default deny-all rule (rule 65000). No explicit deny rule is needed, and no additional rules for Azure Load Balancer health probes are required unless the application is behind a load balancer, which is not specified in the scenario.

Answer

0 (no additional rules needed because the default rules block all inbound traffic)

Answer

2 (one allow rule for HTTPS and one deny rule for all other traffic)

Answer

3 (one allow HTTPS, one allow for Azure Load Balancer health probes, and one deny all)

Question 2

A company uses Azure SQL Database with Transparent Data Encryption (TDE) and a customer-managed key (CMK) stored in Azure Key Vault. The Key Vault has a firewall that blocks all public access. The SQL server is a managed service that needs to access the key to perform TDE operations. The Key Vault is in the same Azure region as the SQL server. Which additional configuration is needed?

Accepted Answer

Enable 'Allow trusted Microsoft services to bypass this firewall' in the Key Vault firewall settings. When Azure Key Vault has a firewall that blocks all public access, Azure services like SQL Database that need to access the key for TDE operations must be explicitly allowed. Enabling 'Allow trusted Microsoft services to bypass this firewall' permits the SQL server's managed service identity to authenticate and retrieve the CMK from Key Vault, even when public network access is denied. This setting is required because the SQL server, as a platform-as-a-service (PaaS) resource, does not reside in a virtual network by default and cannot use a private endpoint or service endpoint without additional networking configuration.

Answer

Configure a service endpoint for Microsoft.KeyVault on the SQL server's subnet

Answer

Assign the SQL server's server identity the 'Contributor' role on the Key Vault

Answer

Create a private endpoint for the Key Vault in the SQL server's virtual network

Question 3

You are designing a network security strategy for a multi-tier application. The web tier must be accessible from the internet, but the application and database tiers must only be accessible from the web tier. Which Azure solution should you use to isolate the tiers?

Accepted Answer

Network security groups (NSGs) on each subnet. Network security groups (NSGs) on each subnet are the correct solution because they provide stateful, layer-3/layer-4 traffic filtering at the subnet level. By placing the web tier in a subnet with an NSG that allows inbound HTTP/HTTPS from the internet, and placing the application and database tiers in separate subnets with NSGs that only allow inbound traffic from the web tier subnet (using source IP ranges or service tags), you effectively isolate the tiers while permitting the required east-west traffic.

Answer

Azure DDoS Protection

Answer

Azure Firewall with application rules

Answer

Azure Private Link

Question 4

A company has multiple on-premises web applications that need to be securely published for remote employees. The company uses Azure AD for identity management and wants to apply Conditional Access policies, including multi-factor authentication, to these applications. The security team wants to avoid exposing the on-premises infrastructure to the internet directly. Which Azure service should they deploy to meet these requirements?

Accepted Answer

Azure AD Application Proxy. Microsoft Entra application proxy is the correct service because it provides secure remote access to on-premises web applications without requiring a VPN or opening inbound firewall ports. It integrates natively with Microsoft Entra ID, enabling Conditional Access policies such as multi-factor authentication (MFA) to be applied to these applications. The service works by establishing an outbound-only connection from the on-premises Application Proxy connector to Microsoft Entra ID, ensuring the on-premises infrastructure is never directly exposed to the internet.

Answer

Azure Application Gateway

Answer

Azure Front Door

Answer

Azure VPN Gateway

Question 5

A security team uses Microsoft Sentinel. They want to automatically assign a severity level and an owner to every incident that is created from a specific analytics rule. The owner should be a specific security operations group. Which Microsoft Sentinel feature should they configure to achieve this automation?

Accepted Answer

Create an automation rule that triggers when an incident is created and sets the severity and owner fields.. Automation rules in Microsoft Sentinel allow you to centrally manage incident handling by triggering actions when incidents are created or updated. By configuring an automation rule that triggers on incident creation from the specific analytics rule, you can automatically set the severity and assign the incident to a security operations group (via an Microsoft Entra ID group or user) without custom scripting or manual intervention.

Answer

Modify the analytics rule to include a custom script that runs upon alert generation.

Answer

Use a Logic Apps playbook connected to the analytics rule's alert generation trigger.

Answer

Configure a workbook to filter and manually assign incidents.

Question 6

A company uses Microsoft Defender for Cloud to manage its security posture. The compliance team wants to monitor the subscription's compliance with the Payment Card Industry Data Security Standard (PCI DSS). They need to view a detailed compliance report and track progress over time. What should they do in Defender for Cloud?

Accepted Answer

Add the PCI DSS standard from the regulatory compliance dashboard.. The regulatory compliance dashboard in Microsoft Defender for Cloud allows you to add built-in compliance standards like PCI DSS. Once added, the dashboard automatically assesses your subscription against the standard's controls, provides a detailed compliance report, and tracks progress over time with a compliance score and historical trend. This is the direct method to monitor PCI DSS compliance without needing to enable specific Defender plans or create custom initiatives.

Answer

Enable the relevant Defender for Cloud plans (e.g., Defender for Servers, Defender for SQL).

Answer

Create a custom regulatory compliance initiative based on PCI DSS controls.

Answer

Configure continuous export to send compliance data to a Log Analytics workspace.

Question 7

A company deploys a public-facing web application behind Azure Application Gateway. They want to enable the Web Application Firewall (WAF) to protect against SQL injection and cross-site scripting attacks. During the initial testing phase, they want to identify malicious requests without blocking them, to tune the WAF rules before enabling full protection. Which WAF mode should they configure?

Accepted Answer

Detection mode. Detection mode logs WAF alerts and records the full request details without blocking any traffic. This allows the security team to analyze malicious requests, tune rule exclusions, and validate that legitimate traffic is not falsely flagged before switching to Prevention mode. It is the correct choice for the initial testing phase described.

Answer

Prevention mode

Answer

Logging mode

Answer

Off

Question 8

A security team uses Microsoft Defender for Cloud to monitor the security posture of a hybrid environment that includes on-premises servers connected via Azure Arc. They want to enable a vulnerability assessment solution that automatically scans all servers (both Azure VMs and on-premises Arc-enabled servers) for OS vulnerabilities. Which solution should they enable directly from Defender for Cloud?

Accepted Answer

Enable the integrated vulnerability assessment solution (Qualys) in Defender for Cloud. The integrated vulnerability assessment (VA) solution in Defender for Cloud, powered by Qualys, is the correct choice because it is a native, built-in capability that can be automatically enabled for both Azure VMs and Azure Arc-enabled on-premises servers. It requires no additional licensing or external configuration, and it automatically discovers and scans OS vulnerabilities without manual intervention, directly from the Defender for Cloud portal.

Answer

Enable Microsoft Defender for Endpoint and integrate it with Defender for Cloud

Answer

Configure Azure Update Management to assess missing patches

Answer

Use Azure Policy to deploy the Log Analytics agent and manually enable scanning

Question 9

A company uses Microsoft Defender for Cloud. They have assigned a custom regulatory compliance initiative that includes policies to enforce encryption on storage accounts and SQL databases. They want to automatically remediate any non-compliant resources that are discovered, without manual intervention. Which feature should they configure?

Accepted Answer

Enable 'Remediation' for each policy assignment in the custom initiative. The 'Remediation' setting on a policy assignment in Azure Policy (used by Defender for Cloud custom initiatives) creates a managed identity and a remediation task that automatically applies the required encryption configuration to non-compliant resources. This ensures that when a storage account or SQL database is found without encryption, the policy engine triggers a deployment to enforce encryption without manual intervention.

Answer

Enable 'Auto provisioning' for the relevant extensions

Answer

Enable 'Just-in-time (JIT) VM access'

Answer

Enable 'Workflow automation' to trigger a Logic App when non-compliance is detected

Question 10

A company has Azure AD Conditional Access policies that require multi-factor authentication (MFA) for all users accessing sensitive cloud apps. The security team wants to extend this protection by monitoring and controlling user activities within those applications (e.g., preventing data exfiltration during a session). Which Conditional Access session control should they implement?

Accepted Answer

Session control: Conditional Access Application Control. Conditional Access Application Control (also known as Microsoft Defender for Cloud Apps session control) allows real-time monitoring and control of user activities within cloud apps, such as blocking downloads or preventing data exfiltration. This session control works by redirecting user traffic through Microsoft Defender for Cloud Apps as a reverse proxy, enabling granular policy enforcement during the session. The requirement specifically asks for monitoring and controlling activities inside the app, which goes beyond just requiring MFA at sign-in.

Answer

Grant control: Require MFA

Answer

Session control: Use app enforced restrictions

Answer

Session control: Sign-in frequency

Question 11

A security team uses Microsoft Sentinel. They create a scheduled analytics rule that queries Azure Activity Logs to detect virtual machines deployed in non-approved regions. The rule generates an incident. The team wants the incident to be automatically assigned to the 'Infrastructure' team and its severity set to 'High' when it is created. Which automation feature should they use?

Accepted Answer

Create an automation rule with trigger 'When incident is created' and actions to assign the incident to an owner and set severity. Automation rules in Microsoft Sentinel allow you to define triggers such as 'When incident is created' and then perform actions like assigning the incident to an owner and setting its severity. This is the native, no-code way to automate incident management without requiring a playbook or modifying the analytics rule itself.

Answer

Create a playbook triggered by alert creation that performs the assignment and severity change

Answer

Use an automation rule with trigger 'When incident is updated' and condition on alert type

Answer

Configure the analytics rule directly to set severity and owner

Question 12

A security team uses Microsoft Sentinel. They want to detect a potential privilege escalation scenario: when a user is added to the Global Administrator role in Azure AD (audit log) and within 10 minutes that user signs in from a suspicious location (sign-in log). Which type of analytics rule should they create to correlate these two different log sources?

Accepted Answer

Scheduled query rule. A scheduled query rule is the correct choice because it allows you to define a KQL query that joins the AuditLogs table (for role assignment events) with the SigninLogs table (for sign-in events) and then uses a time window (e.g., 10 minutes) to correlate the two disparate log sources. This rule type supports cross-table joins and custom time-based correlation, which is exactly what is needed to detect a user added to Global Administrator followed by a suspicious sign-in.

Answer

Fusion rule

Answer

Anomaly rule

Answer

NRT rule (Near Real-Time)

Question 13

Your company uses Azure Firewall to protect a virtual network. The security team needs to allow outbound HTTPS traffic from a specific subnet to a set of FQDNs, such as '*.contoso.com', while blocking all other outbound traffic. Which type of Azure Firewall rule should they configure?

Accepted Answer

An application rule with the 'Https' protocol and the target FQDNs set to '*.contoso.com'. Azure Firewall application rules are specifically designed to allow outbound HTTP/HTTPS traffic based on fully qualified domain names (FQDNs). By configuring an application rule with protocol 'Https' and target FQDNs set to '*.contoso.com', the firewall inspects the TLS Server Name Indication (SNI) extension to match the requested domain, allowing traffic only to the specified FQDNs while blocking all other outbound traffic.

Answer

A network rule with destination port 443 and protocol TCP, and the destination IP address set to the resolved IPs of the FQDNs

Answer

A NAT rule that translates the source IP to a public IP and allows traffic to any destination on port 443

Answer

A DNAT rule that redirects outbound HTTPS traffic to an internal proxy server

Question 14

A security administrator is troubleshooting network connectivity to an Azure virtual machine. The VM is behind a network security group (NSG) that has a deny-all inbound rule as the default. The administrator wants to quickly verify whether a specific TCP packet on port 3389 from their client IP (203.0.113.50) would be allowed or blocked by the NSG. Which Azure Network Watcher tool should they use?

Accepted Answer

IP flow verify.. IP flow verify is the correct tool because it tests whether a specific packet (source IP, destination IP, protocol, port) is allowed or denied by an NSG or virtual network (VNet) route. In this scenario, the administrator needs to quickly validate inbound TCP traffic on port 3389 from client IP 203.0.113.50 to the VM, and IP flow verify provides a pass/fail result along with the exact rule that caused the outcome.

Answer

Network Performance Monitor.

Answer

Next hop.

Answer

NSG diagnostics (flow logs).

Question 15

You are deploying a web application in Azure that must be accessible only from your corporate network via HTTPS. You have an Azure Application Gateway with a Web Application Firewall (WAF) policy. Your corporate network uses public IP addresses from a specific range. Which configuration should you use to restrict access?

Accepted Answer

Configure a WAF policy with a custom rule to allow traffic only from the corporate IP range and deny all other traffic.. Azure Application Gateway's WAF policy supports custom rules that can inspect source IP addresses and allow or deny traffic based on them. By creating a custom rule with a condition matching the corporate public IP range and setting the action to 'Allow', then adding a default 'Deny' rule, you restrict access exclusively to that range over HTTPS. This approach works at the application layer (Layer 7) and is independent of network-level controls, making it the most direct and supported method for IP-based restriction on the gateway itself.

Answer

Create a network security group (NSG) on the subnet hosting the application gateway and allow only the corporate IP range.

Answer

Use Azure Front Door with a WAF policy and geo-filtering to allow only your country.

Answer

Set up a private endpoint for the application gateway and disable public access.
