,Software Development, APIs, and Application Fundamentals
Q1. A network engineer is developing an application that communicates with Cisco
infrastructure using APIs. The application must retrieve device information, analyze
the response, and automatically make configuration decisions. Which approach best
represents the primary purpose of using APIs in this scenario?
A. Replacing all network hardware with software-only solutions
B. Allowing software applications to interact programmatically with network services
C. Eliminating the need for authentication mechanisms
D. Preventing automation by restricting application access
Correct Answer: 🔴 B. Allowing software applications to interact programmatically
with network services
Explanation: 🔹 APIs provide a structured method for software applications to
communicate with services, platforms, and devices. In Cisco environments, APIs enable
automation, monitoring, and integration. Option A is incorrect because APIs do not
replace hardware. Option C is incorrect because APIs commonly require authentication.
Option D is incorrect because APIs are designed to enable controlled automation rather
than prevent it.
Q2. A developer creates a Python script that sends HTTP requests to a Cisco
controller and receives JSON-formatted responses. Which programming concept is
being demonstrated?
A. Hardware virtualization
B. API-based application integration
C. Physical network switching
D. Database normalization
Correct Answer: 🔴 B. API-based application integration
Explanation: 🔹 The script communicates with a Cisco controller through an API
interface and exchanges structured data. This is an example of application integration
,through APIs. Hardware virtualization, switching, and database normalization do not
describe this interaction model.
Q3. A DevNet Associate candidate is designing an application that consumes a REST
API. The developer needs to retrieve information without modifying resources. Which
HTTP method should be used?
A. POST
B. PUT
C. GET
D. DELETE
Correct Answer: 🔴 C. GET
Explanation: 🔹 The HTTP GET method is designed to retrieve resources from a server
without changing data. POST is typically used to create resources, PUT updates
resources, and DELETE removes resources.
Q4. A developer sends a REST API request but receives an HTTP status code of 401
Unauthorized. What is the most likely cause?
A. Invalid authentication credentials or missing authentication information
B. Incorrect JSON formatting only
C. Network bandwidth limitation
D. Unsupported Ethernet speed
Correct Answer: 🔴 A. Invalid authentication credentials or missing authentication
information
Explanation: 🔹 HTTP 401 indicates an authentication problem. The request reached
the service, but the client was not properly authenticated. JSON formatting errors may
cause other responses such as 400 Bad Request. Ethernet speed and bandwidth are
unrelated.
, Q5. An automation engineer wants to store device configuration data in a format
that is lightweight and easily processed by applications. Which data format is
commonly used with REST APIs?
A. JSON
B. VGA
C. SMTP
D. BIOS
Correct Answer: 🔴 A. JSON
Explanation: 🔹 JSON is widely used in modern APIs because it is human-readable,
lightweight, and supported by many programming languages. VGA, SMTP, and BIOS
are unrelated to API data exchange.
Cisco Platforms, Network Automation, and Programmability
Q6. A developer uses Cisco APIs to automate network configuration changes. What is
the main advantage of this approach compared with manual configuration?
A. Increased dependency on repetitive human tasks
B. Faster and more consistent execution of operational tasks
C. Removal of all security requirements
D. Elimination of network design planning
Correct Answer: 🔴 B. Faster and more consistent execution of operational tasks
Explanation: 🔹 Automation improves consistency, reduces manual errors, and allows
repeatable operations. It does not remove security requirements or replace network
planning.
Q7. A company wants developers to build applications using Cisco networking
technologies. Which Cisco resource provides APIs, documentation, learning materials,
and developer tools?
