20+ practice questions focused on Automation — one of the most tested topics on the Cisco DCCOR / CCNP Data Center Core 350-601 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Automation PracticeRefer to the exhibit. An engineer is trying to automate configuration using NX-API on a Nexus 9000 switch. They have enabled 'feature nxapi' but when they attempt to send a POST request to the NX-API endpoint, they receive '400 Bad Request' with 'Invalid message format'. What is the most likely missing configuration?
Explanation: The 400 Bad Request with 'Invalid message format' error occurs because the NX-API HTTP/HTTPS server has not been configured with a port. Without commands like 'nxapi http port 80' or 'nxapi https port 443', the NX-API service does not start on any port. When the POST request is sent to the switch, the management interface receives the request but cannot dispatch it to the NX-API handler, resulting in a 400 error indicating the request format is not understood.
A DevOps team uses Infrastructure as Code (IaC) for data center network automation. They want to adopt a vendor-neutral YANG data model for configuration management. Which YANG model set should they use?
Explanation: OpenConfig is a vendor-neutral YANG model initiative supported by multiple vendors.
A data center engineer is using Ansible to automate NX-OS configuration. They want to ensure that the running configuration is updated and saved to the startup configuration after applying changes to VLANs. Which Ansible module attribute should be used in the nxos_vlan module?
Explanation: The nxos_vlan module does not have a 'save', 'backup', 'startup_config', or 'running_config' parameter. To save the running configuration to startup configuration, use the nxos_config module with the 'save_when' parameter set to 'always' or 'changed'.
A network engineer wants to automate the deployment of a new VLAN across all Cisco Nexus switches in a data center using Python scripts. Which tool is most appropriate for this task?
Explanation: Cisco NX-API provides a RESTful API interface on Nexus switches, allowing direct HTTP/HTTPS calls to configure VLANs programmatically. Using Python's requests library, you can send structured JSON payloads to the API endpoint, making it the most direct and efficient method for script-driven automation without requiring intermediate tools or protocols.
A data center team is troubleshooting an automation script that uses REST API to configure a Cisco Nexus 9000 switch. The script fails with a '401 Unauthorized' error. What is the most likely cause?
Explanation: A 401 Unauthorized error in REST API communication indicates that the request lacks valid authentication credentials. For Cisco Nexus 9000 switches, REST API access typically requires a token-based authentication (e.g., using HTTP Basic Auth to obtain a session token or cookie). If the token is invalid or expired, the API server rejects the request with a 401 status code, as the script cannot prove its identity.

Practice all Automation questions1. Baseline your knowledge
Start with 10 questions to gauge your current understanding of Automation. This tells you whether you need a concept refresher or just practice.
2. Review every explanation
For each question — right or wrong — read the full explanation. Understanding why an answer is correct is more valuable than knowing the answer itself.
3. Focus on exam traps
Automation questions on the 350-601 frequently use trap wording. Look for subtle differences in answers that test your precision, not just general knowledge.
4. Reach 80% consistently
Do repeated sessions until you score 80%+ three times in a row. Then move to mixed-mode practice to test cross-topic recall under realistic conditions.
The exact number varies per candidate. Automation is tested as part of the Cisco DCCOR / CCNP Data Center Core 350-601 blueprint. Practicing with targeted Automation questions ensures you can handle any format or difficulty that appears.
Yes. Courseiva provides free 350-601 practice questions across all exam topics and domains. The platform includes topic-based practice, mock exams, missed-question review, bookmarked questions, and readiness tracking — no account required.
Difficulty is subjective, but Automation is a high-priority exam concept tested in multiple ways — direct recall, scenario analysis, and command-output interpretation. Consistent practice is the best way to build confidence.
