Question 3

Match each CI/CD concept to its definition.

Accepted Answer

Continuous Integration: The practice of automatically building and testing code changes frequently.. Continuous Integration (CI) focuses on merging and automated testing. Continuous Delivery (CD) ensures code is always ready for production deployment but requires manual approval. Continuous Deployment (CDep) automates deployment to production after tests pass. Common confusions involve swapping definitions of CI and CD or CDep.

Answer

Continuous Integration: The practice of automatically deploying code to production after tests pass.

Answer

Continuous Delivery: The practice of merging code changes frequently and automatically testing them.

Question 4

Match each Cisco DevNet Associate exam topic to its description.

Accepted Answer

Software Development and Design: Focuses on design principles, version control, and testing.. The correct matches pair each exam topic with its appropriate description. The Software Development and Design domain emphasizes design, version control, and testing. Understanding and Using APIs focuses on REST, HTTP methods, and authentication. Cisco Platforms and Development involves working with specific Cisco platforms. Common confusions arise from swapping the descriptions of Software Development and Design with Cisco Platforms and Development.

Answer

Software Development and Design: Involves using Cisco platforms like Meraki, Webex, and ACI.

Answer

Understanding and Using APIs: Focuses on design principles, version control, and testing.

Question 5

Match each YAML structure to its description.

Accepted Answer

Mapping: An unordered set of key-value pairs, each separated by a colon and space.. In YAML, a mapping (dictionary) uses key: value pairs; a sequence (list) uses '- ' items; a scalar is a single value. The distractors swap definitions or apply collection concepts to scalars.

Answer

String: true

Answer

Number: "hello"

Question 8

Match each Cisco platform to its primary use case.

Accepted Answer

DNA Center: Centralized network management and automation. The correct matches are: DNA Center for centralized network management and automation, ISE for security policy and access control, and Meraki for cloud-managed networking. Common confusions include mixing up the management scope (DNA Center vs. Meraki) and security functions (ISE vs. DNA Center).

Answer

DNA Center: Security policy and access control

Answer

ISE: Cloud-managed networking

Answer

Meraki: Centralized network management and automation

Question 9

Match each network automation tool to its primary purpose.

Accepted Answer

Ansible: Agentless automation for configuration management and orchestration. Ansible is agentless; Puppet uses client-server; NAPALM abstracts network devices; Netmiko simplifies SSH. Common confusions involve swapping these definitions.
