X-Auth-Token. DNA Center uses an X-Auth-Token retrieved from the authentication service to authorize subsequent API requests.

Answer

OAuth Refresh Token

Answer

Session ID

Answer

Basic Auth Header

Question 3

What is the primary advantage of using JSON over XML when interacting with modern Cisco security APIs?

Accepted Answer

JSON is more concise and reduces bandwidth and parsing latency.. JSON is more lightweight, easier to parse with modern programming languages, and has lower overhead compared to XML.

Answer

JSON allows for better schema validation.

Answer

JSON supports more complex data types.

Answer

JSON is natively supported by the Cisco CLI.

Question 4

Which THREE of the following are valid methods within a Python script to handle potential errors when making API calls to a Cisco platform?

Accepted Answer

Using a try-except block to catch 'requests.exceptions.RequestException'.. Robust API scripts must handle exceptions to prevent crashing and ensure logging of failures.

Answer

Hardcoding a 60-second sleep timer after every API call to ensure the server is ready.

Answer

Ignoring all exceptions to allow the script to continue running indefinitely.

Question 5

You are using Postman to test an API that requires an API key in the header. Where should this be configured in Postman?

Accepted Answer

Headers tab. The 'Headers' tab in the Postman request builder is where you manually add custom HTTP headers.

Answer

Params tab

Answer

Body tab

Answer

Authorization tab

Question 6

Which JSON-related error occurs if you try to parse a string that is missing a closing brace?

Accepted Answer

JSONDecodeError. A 'JSONDecodeError' is raised when the parser encounters a syntax error, such as an incomplete object.

Answer

ValueError

Answer

SyntaxError

Answer

TypeError

Question 7

Which THREE of the following are true about Postman environments?

Accepted Answer

Environments help organize your API collection variables. Environments allow for dynamic variables, switching between test/prod, and storing sensitive data securely.

Answer

Environments allow you to store sensitive API keys in the cloud with no security

Answer

Environments are shared across all Postman users by default

Question 8

When performing an API audit, you want to ensure that all requests are logged. In Postman, which feature can you use to view the raw HTTP request and response details?

Accepted Answer

Postman Console. The 'Postman Console' provides a detailed log of every request sent and the raw response received, including headers and payload.

Answer

Runner

Answer

History tab

Answer

API Documentation

Question 9

Answer

pointer

Question 10

Which THREE of the following are valid HTTP methods supported by REST APIs for managing network configurations?

Accepted Answer

DELETE. GET, POST, and DELETE are standard HTTP methods used in RESTful management.

Answer

TRACE

Answer

CONNECT

Question 11

Which Python library is the standard for performing HTTP requests in an automation script?

Accepted Answer

requests. The 'requests' library is the industry standard for HTTP interaction in Python due to its simple, human-readable API.

Answer

http.client

Answer

socket

Answer

urllib

Question 12

Which THREE of the following are considered best practices for securing API-based automation?

Accepted Answer

Rotating API keys and secrets regularly. Using HTTPS, rotating credentials, and implementing rate limiting are essential for secure automation.

Answer

Allowing unrestricted access to the API port

Answer

Hardcoding API credentials in scripts

Question 13

Which THREE of the following are common benefits of using NETCONF for device management?

Accepted Answer

Structured data format (XML). NETCONF provides transaction-based operations, structured data (XML), and distinct datastores, improving reliability over CLI.

Answer

Native GUI rendering

Answer

Real-time video streaming support

Question 14

In the context of the Cisco Adaptive Security Appliance (ASA) REST API, what does a 'PATCH' method perform compared to a 'PUT' method?

Accepted Answer

PATCH updates only the specified fields, while PUT replaces the entire resource.. A PATCH method is intended for partial updates to a resource, whereas a PUT method typically replaces the entire resource.

Answer

There is no difference; they are interchangeable.

Answer

PATCH creates a new resource, while PUT updates an existing one.

Answer

PATCH deletes the resource, while PUT updates it.

Question 15

A network engineer is testing a Cisco ASA REST API call using Postman. The request returns a 401 Unauthorized status code. What is the most likely cause of this error?

Accepted Answer

The authentication token is missing or expired.. A 401 status indicates that the request lacks valid authentication credentials.

Answer

The requested resource does not exist on the ASA.

Answer

The JSON payload is malformed.

Answer

urn:ietf:params:netconf:capability:write-only

Question 18

When working with Cisco security APIs, which authentication mechanism is most commonly required to maintain a session after the initial credentials have been exchanged?
