Pass the Cisco CCNP Enterprise 300-435 Questions and answers with CertsForce

 To attach a device template in Cisco SD-WAN, you must issue a POST call to initiate the attach action. This is the first step in the process. After initiating the attach action, you need to monitor the status of the action. For this, you issue a “monitor device action status” GET API request with the process ID. The process ID is used to track the status of the attach action until it is completed.

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 YANG module tree diagram represents the data model for network configuration and state data used by management protocols like NETCONF and RESTCONF. In this diagram, containers are denoted by curly braces {} and represent groupings of related data within the model. The three containers identified in the image are “interface,” “statistics,” and “discontinuity-time,” which organize related configuration or state information.

 Zero-Touch Provisioning (ZTP) is a method for automating the configuration of network devices upon initial power-up using DHCP and TFTP. It minimizes manual intervention, streamlining the deployment process and reducing errors. References := ( Automating Cisco Enterprise Solutions Official Cert Guide )

 Python virtual environments should be used in cases where there are conflicting Python package versions across multiple projects (Option B) to ensure each project can have its own set of dependencies. Additionally, they are beneficial when starting a new project that requires a clean development environment (Option E), as it allows for a controlled setup without interference from other projects’ dependencies. References := ( Automating Cisco Enterprise Solutions Official Cert Guide )

 In RESTCONF API calls, when specifying the content type in HTTP headers for requests or responses involving YANG-modeled data, ‘yang-data+json’ is used as part of the ‘Accept’ or ‘Content-Type’ headers to indicate that the message body contains JSON-encoded YANG-modeled data.

In this Python script using RESTCONF, ‘yang-data+json’ completes the highlighted areas because it specifies that JSON format is expected in response which conforms with YANG data modeling standards.

 Cisco IOS XE Software supports two main data modeling languages for its network programmability interface: RESTCONF and NETCONF. RESTCONF provides an API that uses HTTP methods for a programmatic interface over HTTP/HTTPS web services with support for both JSON and XML data formats. On the other hand, NETCONF is a protocol defined by the IETF that also provides a programmatic interface but only supports XML as its data format. Therefore, the statement that RESTCONF supports JSON and XML while NETCONF supports only XML is true. References: Automating Cisco Enterprise Solutions Official Cert Guide

 In NETCONF telemetry subscriptions with Cisco IOS XE devices, the correct XML tag to complete the subscription is “period”. This tag defines the interval in milliseconds at which the telemetry data will be collected and sent. The “period” tag is used to set a fixed time interval for data collection, as opposed to other options like “frequency” which would imply a rate of occurrence or “cadence” which refers to the flow or rhythm of events. References := ( Automating Cisco Enterprise Solutions Official Cert Guide )
