A global logistics company operates hundreds of edge routers configured individually via SSH CLI scripts. Due to subtle differences introduced during manual troubleshooting over time, routine network changes frequently lead to unexpected outages. Which primary operational shift occurs when this network adopts an automated, intent-based management system to handle configuration updates?
A network engineering team is evaluating configuration management mechanisms (Ansible, Puppet, and Chef) for automated network device provisioning, compliance auditing, and state enforcement across an enterprise infrastructure. Which of the following statements correctly describe the underlying architectural capabilities, transport protocols, or configuration artifacts of these tools? (Select TWO.)

During a network topology change in an enterprise environment, a network team evaluates how routing updates are processed. In a traditional distributed network, each router independently recalculates its routing table using its local control plane. Which statement correctly describes how control plane processing is handled in a controller-based network during the same topology change?
Which network configuration management tool uses a pull-based client architecture where managed devices pull configuration definitions organized into Ruby-based recipes and cookbooks from a master server?
A network administrator retrieves interface state data from a Cisco IOS XE device using a RESTCONF GET request. Match each JSON key from the returned payload to its correct JSON data structure or data type based on standard JSON syntax rules.
{
"ietf-interfaces:interface": {
"name": "GigabitEthernet0/0/1",
"enabled": true,
"speed": 1000,
"ietf-ip:ipv4": {
"address": [

A Python network automation script stores the following JSON response from a Cisco Catalyst Center API in a dictionary variable named `data`:
{
"response": [
{
"siteId": "USA-NY-OFFICE",
"devices": [
{
"hostname": "Core-Rtr-01",
"managementIp": "192.168.1.1",
"upTimeSeconds": 86400,
"isReachabilityHealthy": true,
"modules": [
{"slot": 0, "status": "OK", "serialNumber": "FOC12345678"},
{"slot": 1, "status": "FAIL", "serialNumber": "FOC87654321"}
]
},
{
"hostname": "Dist-Sw-01",
"managementIp": "192.168.1.2",
"upTimeSeconds": 43200,
"isReachabilityHealthy": false,
"modules": [
{"slot": 0, "status": "OK", "serialNumber": "FOC11223344"}
]
}
]
}
]
}
Which Python expression correctly retrieves the serial number of the failed module on `Core-Rtr-01`, and what is the data type of the returned value?
A network engineer needs to update the description field of an existing interface resource on a router using a RESTful API. The requirement specifies that only the description attribute should be modified, while leaving all other existing configuration parameters for that interface unchanged on the server. Which HTTP verb and payload strategy should be selected to perform this operation?
A network operations team needs to automate configuration management across a network of Cisco IOS XE routers. Organization policy strictly forbids installing specialized agent software or extra daemons on network devices. Furthermore, the automation workflow requires a push model where playbooks written in YAML are executed from a central machine over standard SSH. Which configuration management tool meets all of these operational requirements?
An enterprise organization implements a Software-Defined Networking (SDN) architecture that decouples control plane operations to a centralized controller while maintaining distributed data plane operations on edge switches. If the Southbound API connection between an edge switch and the centralized controller fails unexpectedly, how does the switch handle existing, established data traffic?
A network operations team switches from per-device manual command-line configuration to centralized template-based automation. Which primary operational advantage does this shift deliver?
A network administrator is evaluating the core architectural differences between traditional networking and controller-based software-defined networking (SDN). In a controller-based architecture, how is the control plane managed compared to a traditional network?
A junior network technician is reviewing device configuration procedures for a new campus deployment. Which key architectural difference characterizes a controller-based network when compared to a traditional network architecture?
In a software-defined fabric deployment, an engineer is preparing the physical network switches prior to building virtual tunnels. Which essential service must the underlay network provide to enable overlay operational functionality?
In a Cisco Software-Defined Access (SD-Access) architecture, which function is strictly the responsibility of the physical underlay network?
