 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 )

MQTT is a lightweight messaging protocol that uses a publish/subscribe model. This means that clients can subscribe to topics, and when a message is published to that topic, all subscribers receive the message. It’s designed for connections with remote locations where a small code footprint is required or network bandwidth is limited. 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 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 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 ‘name’ parameter is essential as it defines the unique identifier for the network within the organization. The ‘type’ parameter determines the kind of network to be created, such as wireless or switch. These two parameters are crucial for the initial setup of a network using the Cisco Meraki API. References := (Automating Cisco Enterprise Solutions Official Cert Guide)

 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)

The error is due to Command Runner in Cisco DNA Center being designed to support only the execution of ‘show’ commands or other read-only commands. When an engineer tries to execute configuration commands or any commands that are not read-only, they will be blocklisted as these are not supported by Command Runner. This ensures that Command Runner is used strictly for retrieving information without making any configuration changes to devices. References := (Automating Cisco Enterprise Solutions Official Cert Guide)

The provided exhibit likely shows a POST request setup in an API testing tool like Postman, with JSON formatted data specifying commands for configuring a network device interface. These commands are not supported by Command Runner as it does not allow configuration changes, only read operations.

REST API calls are characterized as being stateless and implemented over HTTP. Being stateless means that each request from client to server must contain all of the information needed to understand and complete the request; there is no session state stored on the server. Implemented over HTTP indicates that REST APIs use standard web protocols for communication. References: Automating Cisco Enterprise Solutions Official Cert Guide

To access the hostname from the JSON data assigned to the variable “d”, one must navigate through the nested dictionaries and lists. The correct syntax in Python for accessing a dictionary is using square brackets with the key as a string. Therefore, ‘d[“data”]’ accesses the value associated with the key “data”, which is a list. ‘[0]’ accesses the first item in that list, which is another dictionary. Finally, ‘[“host-name”]’ retrieves the value associated with “host-name” from that dictionary. 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.

 Native YANG models are specific to a vendor’s platform, incorporating proprietary features, whereas OpenConfig models are vendor-neutral and created for interoperable use across different platforms.

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

 To resolve the issue of end users not being able to connect to the network and poor signal strength with a missing or unknown APN status message, one should use the device/cellular/status vManage resource URI. This resource allows for checking the cellular interface’s status, including radio signal strength, which is crucial for maintaining a reliable connection. Ensuring that there is sufficient radio signal strength can help resolve connectivity issues and improve network performance. References: Automating Cisco Enterprise Solutions Official Cert Guide

To retrieve information about a rebooted device using the Cisco SD-WAN vManage Administration APIs, you need to construct a REST call with the HTTP GET method. The base URL is  , where you replace vmanage-ip-address with the actual IP address of your vManage instance. The query parameter deviceId is appended to the URL with the value 260faff9-2d31-4312-cf96-143b46db0211, which is the unique identifier of the device. References := (Automating Cisco Enterprise Solutions Official Cert Guide)

The ENAUTO exam tests knowledge of implementing enterprise automated solutions, including programming concepts, Python programming, APIs, controllers, and automation tools. Without the specific Python code from the exhibit, I can’t provide the expected output. Generally, Python code in the context of ENAUTO might involve interacting with APIs or automating network configurations. The output would depend on the code’s function, such as retrieving data from an API or configuring network devices. References := Automating Cisco Enterprise Solutions Official Cert Guide

 The two Netmiko methods used to configure a device are send_config_set() and send_config_from_file(). The method send_config_set() is used to send configuration commands to a network device in an interactive session. This can be done as part of an automated script or manually entered commands. On the other hand, send_config_from_file() allows for sending configurations from a file which can be useful for larger configurations or standard config deployments across multiple devices. 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 insert the project into Git using the account python_programmer, one would need to initialize the local directory as a Git repository, add files to it, commit those files with an appropriate message, add a remote repository URL pointing to where the repository should be pushed on GitHub under python_programmer’s account, and finally push the changes up to that remote repository. Option A follows this process correctly: ‘git init’ initializes the local directory as a Git repository; ‘git add “device_status.py”’ stages changes; ‘git commit -m “Initial Revision”’ commits staged changes with message; ‘git remote add origin 6’ adds new remote repo; ‘git push -u origin master’ pushes committed changes up to GitHub. 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)

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’.

In Cisco DNA Center Operational Tool API, the Command Runner section of the intent API is designed to retrieve keywords accepted by CLI and enables execution of read-only commands on network devices. This feature allows administrators to retrieve real-time configuration data from devices without making any changes, aiding in monitoring and troubleshooting tasks. References: Automating Cisco Enterprise Solutions Official Cert Guide

 To create a new feature in a separate branch and check out the new version, the correct commands are needed. Option B provides the correct sequence of Git commands to achieve this task. The command git checkout -b feature creates a new branch named “feature” and switches to it immediately, which is exactly what is required when starting development on a new feature while keeping the production release intact in the “master” branch. References := ( Automating Cisco Enterprise Solutions Official Cert Guide )

When integrating a Grafana dashboard with Cisco DNA Center to receive network events, the integration bundle that is enabled is:

• C: Network Events for REST API Endpoint. This integration allows Grafana to receive network event notifications from Cisco DNA Center. The REST API Endpoint serves as the interface through which Grafana can subscribe to and receive network events, which can then be visualized on the dashboard1.

YANG-push telemetry data offers several benefits over traditional data collection methods such as SNMP polling. One significant advantage is that it uses less bandwidth because it sends updates only when there’s a change in subscribed data, rather than repeatedly polling all devices at regular intervals regardless of changes. This makes it more efficient and reduces unnecessary network traffic. Additionally, YANG-push telemetry scales better than SNMP because it can handle more frequent updates from a large number of devices without overwhelming the network or management systems. References := ( Automating Cisco Enterprise Solutions Official Cert Guide )

The exhibit is a read-only YANG leaf ("ro vlan") therefore is classed as "state" date and not config data. As such the statement is what you need to use to interact with this particular YANG model. Reference documentation:

This API endpoint is used to retrieve detailed information about issues detected by Cisco DNA Center, including the impacted hosts and suggested actions for resolution. It provides a comprehensive view of the network issues, which is essential for troubleshooting.
