Cisco 300-435 Automating Cisco Enterprise Solutions (ENAUTO) Exam Practice Test

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 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 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.

 When using the Cisco Meraki API to create a network, two mandatory parameters are “type” and “organizationId”. The ‘type’ parameter specifies what kind of network is being created (e.g., wireless, switch, security appliance), while ‘organizationId’ links the new network to a specific organization within Meraki’s system. 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)

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

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

 Webhooks generated by Cisco DNA Center use REST calls to deliver notifications. Specifically, they utilize JSON payloads delivered via POST requests. These webhooks are essential for real-time event handling and automation.

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

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

Python virtual environments are a tool used to create isolated Python environments, each with its own set of dependencies. This isolation is beneficial for several reasons:

• D: Virtual environments allow developers to create a Python environment quickly for testing and debugging purposes. This is because each virtual environment can have its own set of dependencies, which may be different from those installed globally or in other virtual environments. This isolation helps ensure that the environment reflects the production environment as closely as possible, which is crucial for accurate testing and debugging12.
• E: They enable the creation of an isolated Python environment with module dependencies. This means that the dependencies installed in a virtual environment do not affect the system-wide Python installation or other virtual environments. This isolation prevents conflicts between project dependencies and allows for more precise control over the environment in which your code runs12.

Operation Id: syncDevices

Description: Sync the devices provided as input

curl -L --request PUT \

--url /dna/intent/api/v1/network-device \

--header 'Accept: application/json' \

--header 'Content-Type: ' \

--data '{ "type": "COMPUTE_DEVICE" }'

AND

Operation Id: syncDevicesNetworkDevice

Description: Synchronizes the devices. If forceSync param is false (default) then the sync would run in normal priority thread. If forceSync param is true then the sync would run in high priority thread if available, else the sync will fail. Result can be seen in the child task of each device.

curl -L --request PUT \

--url /dna/intent/api/v1/network-device/sync \

--header 'Accept: application/json' \

--header 'Content-Type: ' \

--data '{}'

 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.

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:

 When adding a device to a site using the Cisco DNA Center Sites API, you need to know the site identifier. If you only have the site name, you can retrieve the site identifier by making an API call to /dna/intent/api/v1/site. This call will provide you with the necessary information to properly add the device to the network.

 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 )

• The Cisco DNA Center Intent API communicates in the northbound direction.
• Northbound APIs are used to expose functionality and data from the controller (such as Cisco DNA Center) to external applications or services.

 To create a new network called “Test” using the Meraki API, the correct URI is the one that uses the POST method to the endpoint that includes the organization ID but not a specific network ID. Therefore, option D is the correct answer. 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 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.

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 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 )

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

Graphical user interface, application Description automatically generated

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’.

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 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 )

It can be filtered using the searchBy query and it can be: MAC Address or Device Name value or UUID of the network device

Table Description automatically generated

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.

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)
