, Question 1 (Multiple Choice)
Question:
Which tool is central to Cisco’s DevNet program for providing
programmable, on-demand access to network environments?
- A. Cisco DNA Center
- B. Cisco DevNet Sandbox
- C. Cisco Packet Tracer
- D. Cisco Meraki Dashboard
Correct ANS:
B. Cisco DevNet Sandbox
Rationale:
The DevNet Sandbox offers a risk-free environment where network
engineers and developers can test automation scripts, APIs, and
programmability concepts using real or virtualized Cisco platforms
without impacting production networks.

Question 2 (Fill-in-the-Blank)
Question:
The technology used to deploy network configurations based on YANG
data models and typically exchanging XML payloads is known as
__________.
ANS:
NETCONF
Rationale:
NETCONF is a network management protocol that pairs with YANG to
standardize how configuration data is retrieved, modified, and deleted
on network devices, ensuring consistency in model-driven

,programmability.

Question 3 (True/False)
Question:
True or False: RESTful APIs in network automation rely on standardized
HTTP methods such as GET, POST, PUT, and DELETE to communicate with
network devices.
Correct ANS:
True
Rationale:
RESTful API design leverages HTTP methods for resource manipulation
and is widely adopted in DevNet to enable standardized, stateless
interactions with programmable network elements.
---
Question 4 (Multiple Response)
Question:
Which of the following elements are typically part of a RESTful API
request in DevNet automation? (Select all that apply)
- A. Uniform Resource Identifier (URI)
- B. HTTP method
- C. Request headers
- D. SQL query statements
Correct ANS:
A. Uniform Resource Identifier (URI)
B. HTTP method
C. Request headers
Rationale:
©2025
, A RESTful API request requires a URI to target the resource, an HTTP
method to specify the action, and headers to provide metadata (like
authentication tokens). SQL query statements are unrelated to REST API
communication.

Question 5 (Multiple Choice)
Question:
Within Cisco DevNet, what is the primary purpose of Cisco DNA Center?
- A. Centralizing device configuration backups
- B. Providing a platform for network automation and assurance
- C. Offering cloud storage for network logs
- D. Managing software licensing for Cisco devices
Correct ANS:
B. Providing a platform for network automation and assurance
Rationale:
Cisco DNA Center is designed to enable automation, policy enforcement,
and analytics for enterprise networks, making it an essential tool for
programmability and assurance within the DevNet ecosystem.
---
Question 6 (Fill-in-the-Blank)
Question:
The practice of managing and provisioning infrastructure through
machine-readable definition files, rather than manual configuration, is
known as __________.
ANS:
Infrastructure as Code (IaC)
Rationale:
