| Front | Back |
| CRUD mapping to HTTP verbs? | Create POST Read GET Update PUT or PATCH Delete DELETE |
| How do you authenticate to Cisco DNA Center APIs? | Obtain a token using basic auth then use the token in request headers |
| How do you capture task output in Ansible? | Use the register keyword to store the result in a variable |
| How do you secure telemetry streams? | Use TLS mutual authentication and enforce authorization on collectors |
| How do you version YANG modules? | Use module revision statements and follow semantic versioning practices |
| How does Ansible connect to network devices? | Using connection plugins like network_cli httpapi or netconf depending on platform |
| How does RESTCONF represent YANG data in JSON? | JSON object names map to YANG node names and data types convert to JSON primitives |
| HTTP method for partial updates? | PATCH to modify part of a resource |
| HTTP status code for resource created? | 201 Created |
| HTTP status code for successful GET? | 200 OK |
| JSON vs XML for RESTCONF? | JSON is more concise than XML and is commonly used with RESTCONF |
| Leaf vs leaf list in YANG? | Leaf is a single value node leaf list is an ordered list of values |
| Name an Ansible module for Cisco NX OS? | nxos_config |
| NETCONF RPC to retrieve running config? | get config with source set to running |
| Push vs pull telemetry? | Push initiates from device to collector pull is collector requesting data from device |
| REST API authentication best practice? | Use HTTPS tokens or API keys and avoid embedding credentials in URLs |
| Role of an API schema in automation? | Defines expected request and response structures enabling code generation and validation |
| Streaming telemetry vs SNMP polling? | Telemetry streams real time data to a collector while SNMP polls periodically |
| Typical RESTCONF base URL path? | https device IP restconf data or restconf operations |
| What are RPCs in YANG? | Remote procedures defined by YANG for device specific operations |
| What does an idempotent Ansible playbook ensure? | That running the playbook twice yields no changes after the first run |
| What does CRUD mean in automation? | Create Read Update Delete |
| What does Jinja2 provide in Ansible? | Templating language for dynamic configuration files with conditionals and loops |
| What is a container in YANG? | A grouping of related nodes that may be optional |
| What is a leafref in YANG? | A YANG type that references the path to another node |
| What is a role in Ansible? | A reusable collection of tasks handlers files and templates organized by a standard layout |
| What is a telemetry collector? | A server that receives stores and processes streamed telemetry data |
| What is a YANG module? | A reusable container that defines data nodes types and relationships for a feature |
| What is an Ansible inventory? | A file or source that lists managed hosts and groups |
| What is an Ansible playbook? | A YAML file of plays that define automation tasks to run on hosts |
| What is Cisco DNA Center? | A controller for network automation policy assurance and provisioning in enterprise networks |
| What is Genie? | A pyATS library for parsing and modeling device outputs |
| What is idempotence in automation? | Operation that can be run multiple times with the same result after the first execution |
| What is model driven telemetry? | Streaming device state and performance data to a collector based on data models |
| What is NETCONF? | An XML based protocol that uses RPC over SSH for configuring and retrieving device data |
| What is OpenConfig? | Vendor neutral YANG models for consistent telemetry and configuration |
| What is pyATS? | Cisco Python test automation framework for network testing and verification |
| What is RESTCONF? | A RESTful protocol for accessing YANG modeled data on network devices over HTTPS |
| What is Swagger OpenAPI used for? | Describing REST APIs operations parameters and models |
| What is the default port for NETCONF? | TCP port 830 |
| What is the primary purpose of YANG? | Define data models for configuration state and RPC operations |
| What is XPath used for in NETCONF? | To filter XML data during get and get config operations |
| What is YANG augmentation used for? | To extend existing YANG modules with additional nodes |
| What port does RESTCONF use by default? | HTTPS port 443 |
| What tool is commonly used to test REST APIs? | Postman or curl |
| Which headers are required for RESTCONF content negotiation? | Accept and Content Type headers indicating application yang data plus json or xml |
| Which protocol is commonly used for streaming telemetry? | gNMI over gRPC with TLS |
| Which Python library is used for NETCONF? | ncclient |
| Which Python library is used for REST APIs? | requests |
| YANG statement to define list key? | key inside list declares the unique key leaves |
