Cisco Designing, Deploying and Managing Network Automation Systems Exam Practice Test
Network automation engineering turns service requests into controlled, repeatable changes across network infrastructure. The practice bank samples topics such as API design, structured data models, configuration management, telemetry calculations, workflow validation, and coordinating concurrent operations. These concepts support automation systems that apply device changes and verify that the intended service outcome occurred.
Exam overview
About the Cisco Designing, Deploying and Managing Network Automation Systems Exam
Automation work involves more than issuing device commands. Engineers define and validate service inputs, translate them into vendor-neutral models, and manage configuration through version-controlled files so changes can be reviewed and applied consistently. API decisions include handling paginated inventory results and tracking long-running jobs without keeping a client connection open. Operational safeguards can include locking or other coordination when workers might modify the same device, and enforcing maintenance windows before a workflow runs. Telemetry tasks require interpreting measurements over time—for example, using elapsed time alongside counter differences to calculate a rate. After deployment, workflows should check observed state or service behavior against the requested outcome, rather than treating a successful change response as proof of success. The bank’s scenarios provide practice reasoning through these kinds of implementation and operational choices; they do not establish official exam domains.
Sample Practice Questions
Review a selection from this exam's published US Practice Tests practice bank.
A workflow reports that a device change succeeded, but the team needs evidence that the intended service outcome actually occurred. What should the workflow do next?
Show answer
Correct answer: APost-change verification checks the operational outcome, such as reachability or service health, against explicit criteria. A successful command response alone does not prove the service behaves as intended.
A telemetry collector receives counters at irregular intervals and must calculate the traffic rate between samples. Which information is essential for a meaningful rate calculation?
Show answer
Correct answer: AA rate is derived from the change in a counter divided by elapsed time, so both counter readings and their timestamps are needed. The collector should also account for counter resets or rollover when interpreting the result.
A network inventory contains devices from multiple vendors, each with different command-line syntax. What is the main benefit of using a vendor-neutral data model in an automation system?
Show answer
Correct answer: BA vendor-neutral model represents common network concepts consistently, allowing automation workflows to operate across device types while vendor-specific adapters handle differences. It does not eliminate authentication or make vendor capabilities identical.
A team wants to define network device configurations in version-controlled files and apply them consistently across many devices. Which practice best supports this goal?
Show answer
Correct answer: AManaging configuration intent as code makes changes reviewable, repeatable, and reusable. Automation can render that intent for target devices and apply it consistently.
A workflow runs steps that may take several minutes, and users need to check its status without holding an HTTP connection open. Which API pattern is most suitable?
Show answer
Correct answer: AAn asynchronous job pattern acknowledges the request promptly and provides a status resource for progress and results. It avoids long-lived client connections while preserving visibility into execution.
Two automation workers may process requests for the same device at the same time. What control most directly reduces conflicting concurrent changes?
Show answer
Correct answer: AA per-device lock or equivalent coordination mechanism can serialize conflicting operations on the same target. This helps prevent overlapping workflows from producing unpredictable results.
A network automation workflow must make changes during a restricted maintenance window. Which mechanism best ensures the workflow respects that operational constraint?
Show answer
Correct answer: AA machine-enforced scheduling or policy gate can verify that execution is permitted at the time of the requested change. This is more reliable than relying on an operator's memory or unrelated connection settings.
How to use this practice test
Access the free practice bank for this exam and work through a session of up to 20 randomly selected questions. Use each scenario to identify the relevant automation decision, such as input validation, API behavior, concurrency control, or post-change verification. Results appear after the session, helping you review which concepts need closer attention.
Preparation tips
- For telemetry rate problems, distinguish counter change from rate and account for the elapsed time between samples.
- Trace a service request through input validation, data modeling, configuration application, and verification of the resulting service state.
- Compare API approaches for paginated inventory retrieval and long-running workflows that need status checks.
- Review how version control and vendor-neutral models support consistent configuration across devices with different command syntax.
- For concurrent-change scenarios, identify which coordination mechanism protects a device and how maintenance-window constraints are enforced.
