NEW QUESTION # 89
Fill in the blank to complete the URL for an API call to Cisco SD-WAN to display the history of the Bidirectional Forwarding Detection sessions that run on a vEdge router.
Answer:
Explanation:
bfd/history?
Explanation:
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 '<deviceId>' placeholder. References: ( Automating Cisco Enterprise Solutions Official Cert Guide )

NEW QUESTION # 90
Refer to the exhibit. Which NETCONF statement type is represented by +--rw address* [ip]?
- A. container
- B. submodule
- C. leaf-list
- D. list
Answer: D
Explanation:
Symbols after data node names: "?" means an optional node, "!" means a presence container, and "*" denotes a list and leaf-list.
NEW QUESTION # 91 
Refer to the exhibit. An API request must display an alert message if change in OSPF neighbors is detected. Which code snippet must be added to complete the requests?
- A. Option A
- B. Option B
- C. Option D
- D. Option C
Answer: D
Explanation:
The correct code snippet for detecting a change in OSPF neighbors and displaying an alert message is Option C: This option includes a check for 'OSPF-neighbor-state-change' within the 'Correlation Engine' data returned by the API call. If this key exists and its value is not 0, indicating a state change has occurred, it prints out an alert message "OSPF neighbor change detected!" This logic correctly implements the required functionality.

NEW QUESTION # 92
Refer to the exhibit.
A Python script is used to configure a Cisco IOS XE device. The script must be updated to print the IP addresses of all the loopback interfaces. Which statement should be added before the loop?
- A. interfaces = response.json()["ietf-interfaces:interfaces"]
- B. interfaces = response.json()["ietf-interfaces:interfaces"]["interface"]
- C. interface = response.json()["ietf-interfaces:interfaces"]["interface"]
- D. interface = response.json()["ietf-interfaces:interfaces"]
Answer: B
Explanation:
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.
NEW QUESTION # 93
Refer to the exhibit.

Drag and Drop Question
An engineer must list all networks for a specific Meraki organization. The engineer must call the endpoint of the organization's network and save the returned JSON inventory to disk. Drag and drop the code snippets from the bottom onto the boxes in the code to construct the artifact. Not all options are used.
Answer:
Explanation:
Explanation:
The Meraki Dashboard API authenticates requests with the x-cisco-meraki-api-key header.
Listing organization networks is a read operation, so the correct HTTP method is get. The proper endpoint path is organizations/{org_id}/networks, which returns the network inventory JSON that can then be written to disk.
NEW QUESTION # 98
What is a difference between OpenConfig and native YANG data models?
- A. Native models are developed by individual developers and designed to apply configurations on platforms.
- B. openconfig models are developed by venders and designed to integrate to features or configurations that are relevant only to that platform.
- C. Native models are designed to be independent of the underlying platform and are developed by vendors and standards bodies, such as the IETF.
- D. Native models are developed by vendors and designed to intergrate to features or configurations that are relevant only to that platform.
Answer: D
Explanation:
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.
NEW QUESTION # 99 
Refer to the exhibit. What is a valid XML instances of this YANG module?
- A. Option B
- B. Option C
- C. Option D
- D. Option A
Answer: D
Explanation:
The YANG module defines a structure for network interfaces, including elements such as "name," "address,"
"netmask," and "subnet." The valid XML instance must adhere to this structure. Option A presents an XML instance that correctly reflects the hierarchy and elements specified in the YANG module, with appropriate namespace declarations and values for each element that are consistent with their definitions in the YANG model.

NEW QUESTION # 101
Drag and Drop Question
An engineer must audit Cisco Catalyst Center managed devices to verify configuration sync status. The engineer must authenticate and GET the device list and return the JSON content into a registered variable for later checks. Drag and drop the code snippets from the bottom onto the boxes in the code to construct the artifact. Not all options are used. Options may be used more than once.
Answer:
Explanation:
Explanation:
The Ansible task must use the uri module to call Cisco Catalyst Center APIs. Both the authentication request and the device inventory request specify the HTTP verb with method.
Because the engineer needs the JSON body for later validation, the inventory call must set return_content to true. The result is then stored with register so later tasks can inspect the returned device data.
NEW QUESTION # 102
Refer to the exhibit. What is a valid XML instances of this YANG module?

NEW QUESTION # 103
A cross-functional team is implementing webhook-based monitoring for proactive infrastructure management. To ensure precise incident responses, the automated network orchestrator specifies the enterprise control environment, and encrypted data streaming capability defines the required webhook message delivery format. Which configuration achieves the monitoring goals?
- A. pipeline encryption enabling secure delivery
- B. legacy syslog event parsing routine
- C. CLI-driven output forwarding
- D. DNS-based log collection process
Answer: A
Explanation:
The scenario requires webhook-based monitoring with encrypted data streaming so that incident notifications are delivered securely and in the expected format. Enabling pipeline encryption directly supports secure webhook message delivery and aligns with precise, automated incident response in an orchestrated environment.
NEW QUESTION # 104
Drag and Drop Question
An engineer must enforce hostname compliance on a Cisco IOS XE router using Python over RESTCONF. The engineer must read the current hostname and, if mismatched, set the desired value via a RESTCONF PUT to the correct YANG leaf. Drag and drop the code snippets from the bottom onto the boxes in the code to construct the artifact. Not all options are used. Options may be used more than once.
Answer:
Explanation:
Explanation:
On Cisco IOS XE, RESTCONF configuration data is accessed under the data resource, and the hostname leaf belongs to the Cisco-IOS-XE-native:native model. Reading the current value uses the hostname leaf, and enforcing compliance requires a PUT to that same leaf path so the router updates the configured hostname correctly.
NEW QUESTION # 105 
Refer to the exhibit. If the data included in the code was saved to a python variable named "example".
Which line of code converts if for praising?
- A. Option A
- B. Option B
- C. Option D
- D. Option C
Answer: D
Explanation:
The correct line of code for converting the data saved to the variable "example" into a dictionary is json.loads(example), which is Option C. This function is used to parse JSON formatted strings into a Python dictionary, which is the required operation in this case.

NEW QUESTION # 107
Which two Netmiko methods are used to configure a device? (Choose two.)
- A. send_control_from_file()
- B. send_config_set()
- C. send_command()
- D. send_config()
- E. send_config_from_file()
Answer: B,E
Explanation:
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.
