Master the Cisco Certified DevNet Professional exam with our comprehensive Q&A collection. Review questions by topic, understand explanations, and build confidence for exam day.
Strategies to help you tackle Cisco Certified DevNet Professional exam questions effectively
Allocate roughly 1-2 minutes per question. Flag difficult questions and return to them later.
Pay attention to keywords like 'MOST', 'LEAST', 'NOT', and 'EXCEPT' in questions.
Use elimination to narrow down choices. Often 1-2 options can be quickly ruled out.
Focus on understanding why answers are correct, not just memorizing facts.
Practice with real exam-style questions for Cisco Certified DevNet Professional
A service mesh with a control plane is correct because it provides dynamic service discovery, load balancing, and traffic management for microservices without hardcoding dependencies. Hardcoding IP addresses is not scalable and breaks when services move. Monolithic architecture contradicts the microservices design pattern. Single-host deployment doesn't provide the distributed benefits of microservices and lacks resilience.
Token-based authentication using JWT is correct for Cisco DNA Center. The process involves obtaining a token from the /dna/system/api/v1/auth/token endpoint using basic authentication, then using that JWT token for subsequent API calls. While basic auth is used to obtain the token, it's not sent with every request for security reasons. DNA Center doesn't use OAuth 2.0 for API authentication, and API keys in query parameters are not the standard authentication method.
Implementing exponential backoff with jitter and respecting the Retry-After header is the best practice for handling 429 rate limit responses. This approach prevents overwhelming the API while allowing the request to eventually succeed. Immediately retrying worsens the problem. Switching endpoints doesn't bypass organization-wide rate limits. Increasing concurrent requests will trigger more rate limiting and potentially lead to API access suspension.
StatefulSet is correct because it's specifically designed for stateful applications, providing stable network identities, ordered deployment/scaling, and persistent storage through PersistentVolumeClaims. Deployments are for stateless applications without identity guarantees. DaemonSets ensure pods run on all nodes, not for stateful apps. ReplicaSets maintain pod replicas but don't provide the stateful guarantees needed for databases or applications requiring persistent identity.
An invalid namespace error specifically indicates that the YANG model namespace in the NETCONF RPC doesn't match what the device supports. This is common when using the wrong model version or vendor-specific namespace. If port 830 were blocked, you'd get a connection timeout. If NETCONF weren't enabled, you'd get a connection refused error. Incorrect SSH credentials would result in an authentication failure, not a namespace error.
