Quick Answer
The answer is the Polly library, Azure SDKs with built-in retry policies, and Azure Logic Apps with its connector retry policies. These three options are correct because they each provide a mechanism to handle transient failures—temporary, intermittent errors that occur during network calls or service unavailability—by automatically retrying the failed operation after a brief delay. On the AZ-204 exam, this question tests your understanding of resilient cloud patterns, specifically the retry pattern, and often appears as a multiple-select item where you must distinguish between application-level retry logic and network-level load balancing services. A common trap is confusing Azure Traffic Manager or Front Door with retry logic, but those handle DNS routing and global load balancing, not application retries. For a memory tip, remember that retry logic lives inside your code or service connectors, not at the network edge: think “Polly, SDK, Logic Apps—retry where the code snaps.”
This AZ-204 practice question tests your understanding of connect to and consume azure services and third-party services. 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.
Which THREE Azure services or features can be used to implement retry logic for transient failures when calling an external API from a .NET Core application?
Azure SDK retry policies
Built-in in many SDKs.
Azure Logic Apps retry policy
Configurable retry for connectors.
Polly library
Popular .NET library for retry.
Azure Traffic Manager
Why wrong: DNS load balancer, not retry.
Azure Front Door
Why wrong: Global load balancer, not retry.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Azure SDK retry policies
A, B, and D are correct. Polly is a .NET library for retry logic. Azure SDKs include built-in retry policies. Azure Logic Apps provides retry policies for connectors. Option C is wrong because Azure Traffic Manager is for DNS load balancing, not retry logic. Option E is wrong because Azure Front Door is a global load balancer, not for application-level retry.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
