The correct ncclient method used to collect the running configuration of a Cisco IOS XE device that uses NETCONF is config=m.get_config(source='running'). This method retrieves the specified configuration (in this case, ‘running’) from the device using NETCONF. References: Automating Cisco Enterprise Solutions Official Cert Guide

The primary function of the Cisco SD-WAN vManage Certificate Management API is to install signed certificates on network devices. This process is crucial for establishing trusted communications between devices managed via vManage. References := (Automating Cisco Enterprise Solutions Official Cert Guide)

 The statement ‘D’ is used to assign the list of interfaces from the JSON response to the variable ‘interfaces’. This allows the script to iterate over each interface and print the IP addresses of all loopback interfaces.

In Ansible, the ‘state’ parameter is used to specify the desired state of a resource on the target system. For configuring an NTP server on a Cisco IOS XE device, ‘state: present’ ensures that the NTP server with the specified IP address is configured on the device. The options ‘true’, ‘started’, and ‘installed’ are not valid states for this type of resource in Ansible. The ‘present’ state is used to ensure that an entity exists, which in this case refers to making sure that the NTP server configuration exists without authentication and logging.

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 )

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.
