300-435 Automating Cisco Enterprise Solutions (ENAUTO) Questions and Answers

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

To create a new network using the Meraki API, the correct HTTP action is POST. A POST request to the specified URL with the new organization ID and the required body parameters will create a new network and result in a 201 response code, indicating that the resource has been successfully created.

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 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 )

 Developing an application in a Python virtual environment allows for isolation from other Python projects. This means that the dependencies, Python versions, and libraries for one project will not interfere with those of another, ensuring a clean and controlled development environment.

The correct Python snippet to receive a Meraki webhook request is the one that uses the @app.route decorator with the correct endpoint and accepts the POST method since webhooks typically send data using HTTP POST requests. In this case, Option D is set up to accept POST requests which align with how webhooks operate. References := ( Automating Cisco Enterprise Solutions Official Cert Guide )

The Cisco SD-WAN vManage Certificate Management API is primarily used for certificate-related operations within the SD-WAN fabric. The correct purpose of using this API is:

• A: To generate a Certificate Signing Request (CSR). The CSR is a request sent from an applicant to a certificate authority to apply for a digital identity certificate. It contains information that will be included in the certificate, such as the applicant’s public key and organization details. Once the CSR is generated, it can be signed by a Certificate Authority (CA) to create a certificate1.

MV Sense MQTT API has the capability to request and subscribe to historical, current, or real-time data. This allows applications to receive updates about what’s happening in an environment monitored by Meraki MV smart cameras. 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 )

To create a Cisco Meraki network, the REST API endpoint that should be used is “POST /organizations/{organizationId}/networks”. This POST request is used to create a new network under an organization specified by the {organizationId}. The body of the request would typically include parameters such as name, type, and timezone among others. References := ( Automating Cisco Enterprise Solutions Official Cert Guide )

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.

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: https://blogs.cisco.com/developer/ask-hank-yang-leaves

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

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 )

 In the given RESTCONF GET request response, ‘static-routes’ is referenced as a container within the XML format response from a Cisco IOS XE device. A container in YANG data modeling language groups together related data nodes that are used in network configuration or state data. References: ( Automating Cisco Enterprise Solutions Official Cert Guide )

Zero Touch Provisioning (ZTP) is a method used to automate the process of configuring network devices without manual intervention. When a device is first powered on, it uses DHCP to obtain an IP address and other network settings, including the location of a TFTP server from which it can download its initial configuration. This allows devices to be deployed at scale with minimal effort, as they can automatically configure themselves as soon as they are connected to the network. References := (Automating Cisco Enterprise Solutions Official Cert Guide)

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 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 https://vmanage-ip-address:8443/dataservice/device/reboots , 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 script in Option C is a Python code snippet that uses the requests library to make an API call to bind a network to a template. The URL specifies the API endpoint for Meraki, which is used to manage networks. The payload includes the ‘configTemplateId’ parameter with an example ID value, and ‘autoBind’ set to True, indicating that the network should be bound automatically to the provided template ID. The headers specify that the content type for this request is JSON. Finally, a PUT request is made using these parameters, and the response is printed out. 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

 To replace device configuration using RESTCONF with the Python library Requests, one would use the put() method. The put() method in HTTP is used to update an existing resource or create it if it does not exist. In RESTCONF, which operates over HTTP, using put() will replace the entire target configuration datastore with the payload specified in the request. References: Automating Cisco Enterprise Solutions Official Cert Guide

The Cisco SD-WAN vManage Certificate Management API allows administrators to create certificate signing requests (CSRs). These CSRs can be submitted to a Certificate Authority (CA) for signing, which is essential for secure communication within the SD-WAN deployment. 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 MV Sense API provides various endpoints for different types of data. The endpoint that provides LUX level, which is a measure of light intensity, is option A. References := ( Automating Cisco Enterprise Solutions Official Cert Guide )

• The /dna/intent/api/v1/issues API request provides information about network issues detected by Cisco DNA Center.
• It includes details about the issue, impacted hosts, and suggested actions for resolution.

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
