Match each network management operational mechanism under an automated network model to its primary operational impact.

In Cisco Software-Defined Access (SD-Access) architectures, clear functional boundary separation exists between the underlay, overlay, control plane, and data plane components. Match each SDN fabric component or protocol on the left with its correct primary architectural role or operational mechanism on the right.

An enterprise network engineering team is evaluating architectural shifts during a migration from traditional per-device managed networking to a software-defined, controller-based model. Match each architectural component or interface on the left with its corresponding operational role on the right.

Match each HTTP request method and header combination used in Cisco REST-based API operations (such as RESTCONF and Cisco DNA Center) to its correct operational behavior and CRUD/idempotency characteristic.

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.)

A network engineer is reviewing REST-based API design principles and operational behaviors for network infrastructure automation. Which two statements accurately describe the characteristics of HTTP verbs and CRUD operations when interacting with REST APIs? (Choose two.)

Match each network operation or architectural mechanism to its corresponding structural component in traditional vs. controller-based networking.

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": [
{
"ip": "10.0.12.1",
"netmask": "255.255.255.0"
}
]
}
}
}

Which JSON data type or structure corresponds to each specified key?

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 administrator is verifying SSH remote access on a newly deployed enterprise switch named Dist-SW2. The hostname and IP domain name have been configured, and the administrator generated host keys using the CLI command `crypto key generate rsa modulus 512`. When administrative users attempt to establish remote sessions using SSH version 2, the connections fail. When the administrator executes the `show ip ssh` command on Dist-SW2 to inspect the SSH operational state, which status line is displayed in the output?

A network administrator configures R1 with a primary dynamic route learned via OSPF (Administrative Distance $110$) and a floating static backup route (Administrative Distance $130$) targeting network $10.5.0.0/24$. Place the operational steps performed by R1 in the correct chronological sequence following an interface link failure on the primary path.

An administrator executes the `show ntp associations` command on a Cisco IOS router to verify system time synchronization. The command output is displayed below:

text
address ref clock st when poll reach delay offset disp
~172.16.50.2 10.1.1.1 2 42 64 377 12.45 1.120 0.45
*192.168.20.5 10.1.1.1 2 15 64 377 4.10 0.210 0.15

Based on this output, which statement accurately describes the NTP operational status of the local router?

A network administrator needs to upgrade the Cisco IOS XE system image on a core router from a remote secured FTP server. Arrange the CLI operational steps in the correct chronological sequence required to configure authentication, transfer the image, verify file integrity, and ensure the router boots from the new image upon restart.

A corporate web application suddenly becomes unresponsive after an external adversary directs a massive, synchronized volume of HTTP request traffic from thousands of compromised hosts, fully saturating the internet edge routers. A subsequent incident investigation confirms that no sensitive data was intercepted or modified, but internal employees were completely prevented from accessing the application during the outage. Which principle of the CIA triad was directly violated by this attack?
