20+ practice questions focused on Cisco Platforms and Development — one of the most tested topics on the Cisco DevNet Associate 200-901 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Cisco Platforms and Development PracticeA network engineer needs to automate the configuration of VLANs across 50 switches. Which approach best follows Cisco’s recommended practices for programmability?
Explanation: Option A is correct because Ansible's ios_vlan module is purpose-built for automating VLAN configuration on Cisco IOS devices, aligning with Cisco's recommended practices for programmability by using a declarative, agentless automation tool that abstracts the underlying CLI and ensures idempotent configuration across multiple switches.
A developer is building a chatbot that retrieves interface status from a Cisco Catalyst 9000 switch using RESTCONF. Which authentication method is most appropriate for programmatic access?
Explanation: RESTCONF on Cisco Catalyst 9000 switches supports HTTP Basic Authentication over HTTPS as a straightforward, standards-based method for programmatic access. Basic authentication sends the username and password in the HTTP Authorization header, and when combined with HTTPS, the credentials are encrypted in transit, providing adequate security for device management without requiring additional infrastructure like an OAuth provider or certificate authority.
During a migration from legacy to SD-Access, a network team wants to use Cisco DNA Center to automate policy deployment. They have defined a macro-level intent but need to ensure that the fabric devices are correctly configured. Which API call should they use to validate the fabric configuration?
Explanation: The GET /dna/intent/api/v1/business/sda/fabric-site API call retrieves the current configuration of fabric sites, allowing the team to validate that fabric devices are correctly provisioned and associated with the intended site. This aligns with the intent-based API model where GET operations are used for validation and monitoring of deployed policies.
A Python script uses the Cisco Meraki API to fetch the list of organizations. The script fails with a 401 HTTP status. What is the most likely cause?
Explanation: A 401 HTTP status indicates 'Unauthorized', which in the context of the Meraki API means the request lacks valid authentication credentials. The most common cause is an invalid or missing API key, as the Meraki API requires a valid API key in the `X-Cisco-Meraki-API-Key` header for all requests.
A DevOps team is using Cisco NSO to manage network devices. They want to ensure that the configuration is compliant with corporate standards. Which NSO feature should they use?
Explanation: Service reconciliation using FastMap is the correct NSO feature for ensuring configuration compliance with corporate standards because it detects and corrects deviations between the intended service model (defined in YANG) and the actual device configuration. FastMap performs a diff and re-applies the service logic to bring the device back into compliance, making it ideal for continuous compliance enforcement.
