AZ-400 Practice Question: Design and implement build and release pipelines
This AZ-400 practice question tests your understanding of design and implement build and release pipelines. 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.
You are designing a build pipeline for a Java application hosted in Azure Repos. The pipeline needs to run unit tests, package the application as a JAR file, and publish the build artifact. Which task should you use to publish the JAR file as a pipeline artifact?
Why wrong: Although this task publishes build artifacts, Publish Pipeline Artifact is the modern equivalent and the scenario uses a YAML pipeline where Publish Pipeline Artifact is recommended.
B
Copy Files task
Why wrong: Copy Files copies files to a staging directory but does not publish them as artifacts.
C
Archive Files task
Why wrong: Archive Files creates a ZIP archive but does not publish it as an artifact.
D
Publish Pipeline Artifact task
Publish Pipeline Artifact publishes files as pipeline artifacts that can be used in subsequent stages.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Publish Pipeline Artifact task
Option B is correct because the Publish Build Artifacts task is designed to publish files as build artifacts from a pipeline. Option A is wrong because Copy Files task only copies files to a staging directory. Option C is wrong because the Archive Files task creates a ZIP archive. Option D is wrong because the Publish Pipeline Artifact task is the correct one, but the scenario asks for build artifacts specifically, and Publish Build Artifacts is the classic task; however, Publish Pipeline Artifact is also valid but the question expects the classic task. Actually, both are used, but Publish Build Artifacts is the older task name; the question is designed to test knowledge of the task names. In modern Azure DevOps, Publish Pipeline Artifact is preferred. To avoid confusion, we'll adjust: Option B is Publish Pipeline Artifact. Explanation: Option B is correct because Publish Pipeline Artifact publishes files as pipeline artifacts. Option A is wrong because it only copies files. Option C is wrong because it archives files. Option D is wrong because it's not a valid task name.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

Related concept
Static NAT maps one inside address to one outside address.
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 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.
