This AZ-500 practice question tests your understanding of secure networking. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 public web application should be protected from OWASP-style attacks and network-layer DDoS attacks. Which two Azure services are most relevant?
Application Gateway WAF or Azure Front Door WAF
Correct for the stated requirement.
Azure Automation State Configuration
Why wrong: This does not meet the stated requirement as directly as the correct option.
Azure DDoS Protection on the virtual network where applicable
Correct for the stated requirement.
Azure Files premium tier
Why wrong: This does not meet the stated requirement as directly as the correct option.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Application Gateway WAF or Azure Front Door WAF
Option A is correct because both Azure Application Gateway WAF and Azure Front Door WAF provide managed rule sets (e.g., OWASP Core Rule Set 3.2) that protect against common web vulnerabilities such as SQL injection and cross-site scripting. Option C is correct because Azure DDoS Protection, when enabled on the virtual network hosting the application, mitigates network-layer DDoS attacks (e.g., SYN floods, UDP floods) by leveraging Azure's global infrastructure to absorb and scrub attack traffic.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
The trap here is that candidates may confuse Azure Automation State Configuration (a DevOps tool) with a security service, or assume Azure Files premium tier offers built-in attack protection, when in fact only WAF and DDoS Protection directly address the specified OWASP and DDoS threats.
Detailed technical explanation
Azure WAF operates in detection or prevention mode, inspecting HTTP/HTTPS traffic at Layer 7 using signature-based and anomaly-scoring engines; it can block requests matching OWASP rules before they reach the application. Azure DDoS Protection uses adaptive tuning and traffic telemetry to distinguish legitimate traffic from attack patterns, automatically applying mitigation policies at the Azure network edge, and integrates with Azure Monitor for real-time attack analytics.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
