Which model-driven programmability protocol does Cisco IOS XE Software support?
- A. SOAP
- B. SSH
- C. gNMI
- D. CORBA
Answer: C
Explanation:
Cisco IOS XE supports model-driven programmability using protocols such as gNMI (gRPC Network Management Interface). gNMI is a protocol that provides a way to manage and configure network devices using a standardized approach to data models and APIs.
Model-Driven Telemetry: gNMI is used for streaming telemetry data from network devices.
Configuration Management: It allows for the configuration of network devices using standardized YANG models.

1 - D, 2 - C, 3 - A, 4 - B
NEW QUESTION # 22
Refer to the exhibit.
The Cisco Meraki API manages two organizations. In each organization, two independent networks are defined. How many calls to the /organizations/(orgid)networks endpoint will be run parallel by the GetAllNetwork function of the API client?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: C
Explanation:
The sequence diagram shows the process where the API client first calls the /organizations endpoint to get the list of organization IDs. Then, for each organization, it makes a call to the /organizations/(orgId)/networks endpoint to retrieve the networks for that organization. Since there are two organizations, the GetAllNetworks function will make two parallel calls to the /organizations/(orgId)/networks endpoint, one for each organization.

NEW QUESTION # 23
An automation script fails to connect to an internal server exactly 1 out of 2 times it is executed. This behavior is seen from different clients. Which networking device mut be at fault?
- A. Router
- B. Switch
- C. Load balancer
- D. Laptop on which the script is running
Answer: C
Explanation:
The described behavior, where an automation script fails to connect to an internal server exactly 50% of the time from different clients, suggests an issue with a load balancer. Load balancers distribute incoming network traffic across multiple servers to ensure reliability and performance. If a load balancer is misconfigured or if one of the backend servers is down, the connection might fail intermittently, which aligns with the described 1 out of 2 failure rate.
NEW QUESTION # 24
What is a tenet of test-driven development?
- A. write documentation for tests
- B. write and run tests before writing new code
- C. run tests after writing new code
- D. write tests after adding new blocks of code
Answer: B
Explanation:
Test-Driven Development (TDD) is a software development approach where tests are written before the code that needs to be tested.
* TDD Process:
* Write a Test: Start by writing a test for a new feature or functionality.
* Run the Test: Run the test, which should fail initially since the code hasn't been written yet.
* Write Code: Write the minimum amount of code required to pass the test.
* Run Tests Again: Run the tests again to ensure they pass.
* Refactor: Refactor the code while ensuring the tests still pass.
* Advantages:
* Early Bug Detection: Bugs are detected early in the development cycle.
* Better Design: Promotes writing cleaner, more modular code.
* Documentation: The tests themselves serve as documentation for the code.
Writing and running tests before writing the actual code ensures that the code meets the specified requirements and functions correctly.

NEW QUESTION # 25
What is the purpose of the first three pairs of digits in a MAC address?
- A. indicates vendor of the network card or adapter
- B. defines packet forwarding priority sent or received by the adapter
- C. defines a routing identifier for the client
- D. indicates the IP address of the client in Hex
Answer: A
Explanation:
The first three pairs of digits in a MAC address, also known as the Organizationally Unique Identifier (OUI), identify the vendor or manufacturer of the network card or adapter. This part of the MAC address is assigned by the IEEE to the manufacturers, ensuring that each MAC address is unique.
Reference: Cisco DevNet Associate documentation on networking fundamentals, which explains MAC addresses and their structure.

NEW QUESTION # 31
Refer to the exhibit.
A developer is troubleshooting an API with the given API with the given API documentation and cURL command. What is the cause of this problem?
- A. The user is not allowed to post massages from their account
- B. The request body is missing or incomplete
- C. The API token specified is expired
- D. The authorization header is missing or incomplete
Answer: D
Explanation:
The error message in the cURL response indicates that the request requires a valid access token set in the Authorization request header. This error is common when the authorization header is either missing or the token provided is incorrect or expired.
To resolve this issue, ensure the correct Bearer token is included in the Authorization header, formatted as follows:
-H "Authorization: Bearer YOUR_ACCESS_TOKEN"

* Cisco DevNet Associate Exam Topics: Security and Access Management (understanding how to handle API tokens and authorization)
* Cisco Webex API Documentation (details on how to properly format API requests and handle authorization)
NEW QUESTION # 32
Refer to the exhibit.
A REST API retune this JSON output for a GET HTTP request, Which has assigned to a variable called "vegetables" Using python, which output is the result of this command?
- A. {'color': 'green', 'items': ['kiwi', 'grape']
- B. ['kiwi', 'grape']
- C. Lettuce
- D. Kiwi
Answer: D
Explanation:
* Understand the JSON Structure: The JSON data given in the exhibit consists of an array of objects. Each object has a type and an items key. The items key contains an array of objects, each with a color and another items key, which is an array of strings representing items of that color.
* Analyze the Python Code: The Python code provided is:
print(filter(lambda l: l['type'] == 'fruit', vegetables)[0]['items'][0]['items'][0]) Break Down the Code:
filter(lambda l: l['type'] == 'fruit', vegetables): This line filters the JSON array vegetables to include only objects where the type is 'fruit'.
filter(...)[0]: After filtering, this selects the first object in the filtered list, which is the fruit object.
['items'][0]: This accesses the first item in the items array of the fruit object. In this case, it refers to the object where color is "green".
['items'][0]: This accesses the first item in the items array of the green object, which is "kiwi".
Evaluate the Code:
The first object of type fruit in the JSON is found.
The first item in the items array for fruit with the color green is selected.
The first item in this nested items array is "kiwi".
Therefore, the output of the given Python command is "Kiwi".

What is a benefit of using edge computing in an IoT implementation?
- A. high availability for network components
- B. low cost in network design
- C. low network design complexity
- D. high speed in data processing
Answer: D
Explanation:
Edge computing involves processing data closer to where it is generated (the "edge" of the network) rather than sending it to a centralized data center or cloud for processing. This approach reduces latency and bandwidth usage, providing high-speed data processing capabilities. It is particularly beneficial for IoT implementations where real-time processing and response are crucial.
