The correct combination is validate-jwt, rate-limit, and log-to-event-hub, because these three policies directly address the requirements of token validation, per-subscription-key throttling, and audit logging to Azure Monitor. The validate-jwt policy checks the OAuth 2.0 token from Microsoft Entra ID before the request reaches the FHIR backend, ensuring only authenticated partners proceed. The rate-limit policy enforces a request limit per subscription key, preventing abuse without blocking total usage like quota would. Finally, log-to-event-hub streams request data to an Event Hub, which Azure Monitor can ingest for audit trails. On the AZ-204 exam, this scenario tests your ability to match APIM policies to specific security and throttling needs—a common trap is confusing rate-limit (per-time-window) with quota (total cap), or using check-header instead of validate-jwt. Remember the mnemonic “JWT, Rate, Log” to recall the three pillars: validate identity, throttle usage, and capture telemetry.
AZ-204 Implement Azure security Practice Question
This AZ-204 practice question tests your understanding of implement azure security. 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 healthcare organization uses Azure API Management (APIM) to expose FHIR APIs to external partners. The FHIR backend is an Azure API for FHIR that requires OAuth 2.0 tokens from Microsoft Entra ID. APIM must validate tokens before forwarding requests to the backend. The organization also needs to rate-limit requests per subscription key and log all requests to Azure Monitor for audit. Which combination of APIM policies should be implemented?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use validate-jwt to validate the token, rate-limit to throttle requests per subscription key, and log-to-event-hub to send logs.
Option D is correct because validate-jwt ensures token validation, rate-limit enforces throttling per subscription key, and log-to-event-hub sends logs to Azure Monitor via Event Hubs. Option A is wrong because check-header is not for JWT validation. Option B is wrong because quota limits total calls, not rate. Option C is wrong because set-header is not for validation.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Use validate-jwt, set-header to add the subscription key, and log-to-event-hub.
Why it's wrong here
set-header does not enforce rate limiting.
✗
Use check-header to verify the token, rate-limit to throttle requests, and log-to-event-hub to send logs.
Why it's wrong here
check-header does not validate JWT tokens.
✓
Use validate-jwt to validate the token, rate-limit to throttle requests per subscription key, and log-to-event-hub to send logs.
Why this is correct
This combination meets all requirements.
Related concept
Static NAT maps one inside address to one outside address.
✗
Use validate-jwt to validate the token, quota to limit total requests, and log-to-event-hub.
Why it's wrong here
quota does not provide rate limiting per subscription key.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.

Variation 1. Your company uses Azure API Management to expose APIs to external partners. You need to validate that each incoming request includes a valid JSON Web Token (JWT) issued by your Microsoft Entra ID tenant, and reject requests without valid tokens. What should you configure?
hard
A.Configure an OAuth 2.0 authorization server in API Management
B.Require a subscription key for each API
C.Use an IP access restriction policy
✓ D.Add a validate-jwt policy in the inbound processing policy
Why D: Option D is correct because a validate-jwt policy in the inbound processing pipeline checks the token before the request reaches the backend. Option A is wrong because OAuth 2.0 authorization server doesn't validate tokens per request. Option B is wrong because subscription keys are not tokens. Option C is wrong because IP filtering does not validate tokens.
