To add legacy devices to the Cisco DNA Center platform, it is essential to update the trusted device profile and create device packages. These steps ensure that the legacy devices are recognized and managed correctly by the Cisco DNA Center. Updating the trusted device profile allows the platform to authenticate and trust the legacy devices, while creating device packages enables the platform to understand and interact with the specific features and capabilities of the legacy devices123. References := ( Automating Cisco Enterprise Solutions Official Cert Guide )

NETCONF, unlike RESTCONF, allows for the validation of a candidate datastore before it is committed as the running configuration. This feature ensures that any configuration changes are checked for correctness before they can potentially impact the network operation. 

The JSON instance in the exhibit represents a structured data format for configuring an interface on a network device. The correct answer is “interface-configurations” because the JSON structure starts with “Cisco-IOS-XR-ifmgr-cfg:interface-configurations,” indicating that it pertains to interface configurations within Cisco IOS XR. References: Automating Cisco Enterprise Solutions Official Cert Guide

To create a Python script that pulls inventory for Cisco SD-WAN Viptela devices using the Viptela library, the correct action is:

• C: from viptela.viptela import Viptela. This import statement is used to import the Viptela class from the viptela.viptela module, which is part of the Python SDK for Cisco Viptela vManage. This SDK allows for interaction with Cisco SD-WAN Viptela devices through various API calls, enabling the automation of tasks such as pulling inventory data1.

Text Description automatically generated

 A HTTP 206 status code is returned when the server successfully processes a partial GET request specified by the range header in the client’s request. This is commonly used in situations where large files are being transferred, and the client needs to download or stream only a portion of the file. References := (Automating Cisco Enterprise Solutions Official Cert Guide)

To access the ‘status’ indicated on line 16 in a Python dictionary assigned to variable “d”, you would navigate through the nested structure of the JSON data. Starting with the key ‘data’, which points to a list, you select the first item using [0]. Within this item, ‘statusList’ is a key pointing to another list, and selecting the first item using [0] leads to a dictionary where ‘status’ is the key to the desired value ‘normal’.

The Meraki Location Scanning API is designed to provide location-based services. Mapping and wayfinding solutions are built using this API to help users navigate physical spaces, making options B and E the correct answers. References := ( Automating Cisco Enterprise Solutions Official Cert Guide )

 To create a Meraki webhook Python script that sends a message to Webex Teams, the programmer needs to configure the Webex Teams access token and the webhook server secret. The access token is necessary for authenticating with the Webex Teams API, allowing the script to send messages on behalf of a user or bot. The webhook server secret is used to secure communication between Meraki and the receiving server, ensuring that messages are not tampered with during transit. References: Automating Cisco Enterprise Solutions Official Cert Guide

The JSON formatted output from a network monitoring tool indicates that there is one unmonitored device in the access category. Additionally, the “healthScore” section shows values for “badCount” and “badPercentage” greater than zero, suggesting at least one device in this category has performance issues. Since this falls under the Access category, it can be inferred that an access switch is functioning in a degraded state. References: Automating Cisco Enterprise Solutions Official Cert Guide

• B. The ethernetCsmacd type is imported from the iana-if-type module: This is correct because the XML response shows ethernetCsmacd, indicating that the ethernetCsmacd type is defined within the iana-if-type module.
• D. ipv4 is a container defined in the ietf-ip module: This is accurate as the XML response includes , which specifies that ipv4 is a container within the ietf-ip module.

The Ansible playbook is designed to reset configurations on Cisco IOS XE routers. It includes tasks to remove Loopback1 and Loopback2 interfaces. The condition when: "'pod-2' in ansible_net_hostname" ensures that Loopback2 is only removed from routers with ‘pod-2’ in their hostname. Since pod-11 and pod-12 do not meet this condition, only Loopback1 is removed from them, which leads to the removal of IPv4 and IPv6 addresses for the Loopback1 interface on these routers. References: Automating Cisco Enterprise Solutions Official Cert Guide

 The NETCONF  operation is used to retrieve running configuration and state data from the network device. In the provided exhibit, the  operation includes a filter that specifies two YANG models: Cisco-IOS-XE-native and Cisco-IOS-XE-ntp-oper. The first model, Cisco-IOS-XE-native, is indicated by the namespace “http://cisco.com/ns/yang/Cisco-IOS-XE-native” and includes details such as hostname and IP address within its hierarchy. The second model, Cisco-IOS-XE-ntp-oper, is indicated by the namespace “http://cisco.com/ns/yang/Cisco-IOS-XE-ntp-oper” and includes details related to NTP (Network Time Protocol) associations and status information. Therefore, the NETCONF   operation in this exhibit interacts with two YANG models. References: = ( Automating Cisco Enterprise Solutions Official Cert Guide )

The Cisco SD-WAN manage certificate management API is capable of installing certificates on a vSmart controller device. The vSmart controller plays a pivotal role in establishing secure connections within an SD-WAN architecture by managing security policies and traffic flow throughout the network. References: Automating Cisco Enterprise Solutions Official Cert Guide

The get_config method from the ncclient library is used to retrieve the running configuration from a Cisco IOS XE device using NETCONF. The ‘running’ parameter specifies that the running configuration should be collected. References: (Automating Cisco Enterprise Solutions Official Cert Guide)

To construct the URL for the Cisco SD-WAN API that retrieves a list of users logged into a device, you start with the vManage IP address, followed by /dataservice/ which is the base path for all API services. The segment device/user specifies that we are accessing user information on a device. The query parameter ?deviceId= is then used to specify the unique identifier of the device in question. By replacing deviceId with the actual device ID, you complete the URL.

When making an HTTP GET call to obtain site health from Cisco DNA Centre, the JSON response includes various health indicators. The clientHealthAverage is a key metric that represents the average health of clients connected to the site, which can include both wired and wireless clients. This metric provides a general overview of the client health status within the site. On the other hand, overallBadDevices is another important metric that indicates the number of devices that are in a ‘bad’ state, which could be due to issues like high utilization, errors, or other factors affecting their performance. These two metrics are crucial for administrators to quickly assess the health of the site and identify areas that may require attention or troubleshooting.

To construct this URL, one needs to understand REST API call structure and how it relates to Cisco SD-WAN vManage APIs specifically. The base URL starts with ‘https://’, followed by ‘vmanage-ip-address’ which should be replaced with the actual IP address or hostname of vManage. ‘/dataservice/’ is a common prefix in all vManage REST API calls indicating that data service is being accessed. Following this, ‘/device/bfd/sessions/history’ specifies that we are interested in accessing historical data about Bidirectional Forwarding Detection sessions on devices. Finally, ‘?deviceId=’ is a query parameter where one must provide an actual device ID instead of ‘ ’ placeholder. References: ( Automating Cisco Enterprise Solutions Official Cert Guide )

 The module name that corresponds to the YANG model referenced in the RESTCONF GET request is “ietf-interfaces:interfaces”. This can be determined by looking at the first line of the response in the exhibit, which shows "ietf-interfaces:interfaces": {. This line indicates that the data returned is part of a list defined within the ‘ietf-interfaces’ YANG module and specifically within the ‘interfaces’ container. References: (Automating Cisco Enterprise Solutions Official Cert Guide)

 To automate the creation of a network on the Meraki dashboard that supports only wired network connections, the type ‘switch’ needs to be added to the API. This is because ‘switch’ refers to network switches, which are hardware devices that connect devices on a computer network by using packet switching to receive, process, and forward data to the destination device. In contrast, ‘wireless’ would refer to Wi-Fi connections, ‘appliance’ could refer to security appliances or other types of network equipment not specifically related to wired connections, and ‘systemsManager’ is related to mobile device management. References := ( Automating Cisco Enterprise Solutions Official Cert Guide )

The location accuracy of a device using scanning APIs can be influenced by several factors. AP placement is crucial because it determines signal coverage and strength, which directly affects how accurately a device can be located. The amount of device antennas also plays a significant role; more antennas can provide more data points for triangulation, leading to improved location accuracy. References: (Automating Cisco Enterprise Solutions Official Cert Guide)

The difference between OpenConfig and native YANG data models lies in their development and purpose:

• D: Native models are developed by vendors and are specific to their platforms. They are designed to integrate features or configurations that are relevant only to that vendor’s platform. Native models, being vendor-specific, provide the most detailed and granular control over the vendor’s devices1.

OpenConfig models, on the other hand, are developed by a collaborative group of network operators and are intended to be vendor-neutral. They aim to provide a more standardized model that can be used across different vendors’ equipment, focusing on the needs of the operators rather than the specific capabilities of the devices1.
