An enterprise network implements a Cisco Software-Defined Access (SD-Access) fabric architecture across a routed Layer 3 campus backbone running OSPF. Host A (10.1.10.15) attached to Fabric Edge 1 initiates unicast communication with Host B (10.1.10.22) attached to Fabric Edge 2 across the fabric overlay. Which statement correctly describes the operation and interaction of the underlay and overlay network components during packet transmission?
A network administrator is deploying unconfigured Cisco Catalyst switches at a new enterprise site using Cisco DNA Center Plug and Play (PnP) for automated onboarding. What infrastructure service must be available on the local staging VLAN so the factory-default switches can locate the Cisco DNA Center controller?
A network architect is designing an automated configuration management solution for a large Enterprise network containing hundreds of Cisco IOS XE routers and NX-OS switches. The architecture requirements mandate minimizing device-level software overhead by avoiding persistent agent installations, using standard SSH/NETCONF protocol transport, leveraging YAML-formatted state files, and initiating configuration updates using a push-based model from a control node. Which configuration management tool satisfies all specified requirements, and which operational characteristics define its framework?
A automated network management script receives an HTTP status code of 415 Unsupported Media Type after issuing a POST request containing a structured JSON body to a REST-based API endpoint on a Cisco controller. Which HTTP request header was missing or misconfigured in the client's request payload headers to cause this failure?
A university healthcare network is replacing manual per-device CLI management across its regional campuses with an API-driven, controller-based automation framework. Which two statements describe the operational impacts of this automation framework on network management? (Select two.)

A network administrator needs to retrieve the operational state and configuration details of a specific router interface using a REST API without making any modifications to the device. Which HTTP verb should be used in the API request?
An organization is auditing its infrastructure operational model as it migrates from per-device management to a software-defined controller-based deployment (such as Cisco DNA Center). The network engineering team needs to clarify the architectural and management operational differences between these two models for their automation workflows. Which of the following statements correctly compare traditional networks with controller-based networking? (Select TWO.)

An enterprise branch location is deploying factory-default Cisco Catalyst switches using Cisco DNA Center Network Plug and Play (PnP). Which TWO methods allow an unconfigured switch to automatically locate the Cisco DNA Center controller IP address or hostname during the Day-0 onboarding process? (Choose two.)

A retail enterprise replaces legacy SNMPv3 polling across its distributed branch routers with an automated model using RESTCONF and streaming telemetry. Which operational benefit does the enterprise achieve as a direct result of this architectural transition?
A network automation engineer attempts to create a new syslog host entry on a Cisco router using RESTCONF. The engineer sends an HTTP POST request to the parent container endpoint `/restconf/data/Cisco-IOS-XE-native:native/logging/host`. The API gateway responds with an HTTP status code of `409 Conflict` because a syslog host entry with the specified IP address already exists. Which HTTP request method and URI target combination must the engineer use to completely replace the existing syslog host entry configuration?
An enterprise network engineering team is modernizing its operations infrastructure. Match each operational transition on the left with its corresponding primary benefit to network management on the right.

A network administrator has added a newly discovered Cisco Catalyst switch to the inventory of Cisco DNA Center. The switch is currently listed under the unassigned devices pool. Which task must the administrator perform in Cisco DNA Center before site-level settings, software images, and configuration templates can be pushed to the device?
An enterprise network utilizes a centralized Software-Defined Networking (SDN) controller architecture. During a minor transport network outage, the Southbound API control channel between the SDN controller and a campus access layer switch is temporarily severed. Network monitoring indicates that existing active user sessions continue to forward frame traffic across the switch at wire speed without disruption, but new routing protocol neighbor adjacencies fail to establish and newly connected hosts cannot be populated into the forwarding tables. Which statement accurately explains the underlying separation of planes operating during this control channel outage?
Match each network device operation or architectural component to its corresponding plane of operation or processing path in a modern router or switch architecture.

A network administrator is developing an automation script to interact with a Cisco DNA Center REST API. The script needs to completely replace an existing network device interface configuration resource with a newly provided configuration payload. Which HTTP verb must the administrator use to perform this complete replacement operation?
An enterprise networking team is replacing a legacy campus deployment of fifty access switches that suffer from configuration drift and inconsistent QoS policies. The team evaluates migrating to a software-defined network (SDN) architecture managed by a centralized controller such as Cisco DNA Center. Which statement correctly contrasts how control plane state and policy management differ between these two architectures?
A network automation engineer issues an HTTP GET request to a Cisco IOS-XE RESTCONF API endpoint to retrieve BGP neighbor status details. The router returns the following JSON-encoded response:
