• Question 424:

  What is a comparison of YAML and JSON?

  A. YAML has a more consistent approach to representing data compared to JSON.
  B. JSON does not support comments and YAML does.
  C. YAML is a more verbose data structure compared to JSON.
  D. JSON has more common usage in configuration management tools compared to YAML.
  B. JSON does not support comments and YAML does.

  ---

  YAML and JSON are both data serialization formats often used in configuration files. One of the key differences is that YAML supports comments, whereas JSON does not. Comments: YAML allows comments, which makes it easier to add explanatory notes within the configuration files. Data Representation: Both formats are used to represent data structures, but YAML is often considered more human-readable. Option B is correct as it highlights the difference that YAML supports comments while JSON does not. YAML and JSON Documentation: YAML vs JSON

• Question 425:

  Why should a code review process be used?

  A. It enables various software design implementations.
  B. It enables a consistent software design.
  C. It ensures that members of a team work in isolation.
  D. It ensures that whole software is secure.
  B. It enables a consistent software design.

• Question 426:

  Refer to the exhibit.

  

  A network engineer must collect information from the network using Cisco DNA Center APIs. The script must query for the devices with 'platformId' 'C9540-x' and then send commands to be executed. Which process is automated by the Python script?

  A. results gathering of the show version and show ip int brief commands
  B. output of show ip int brief command on devices of type C9500-40X
  C. execution information of the show version and show ip int brief commands
  D. list of executed commands on C9500-40X and the information of show ip int brief command

• Question 427:

  How are operations on REST APIs performed as compared to RPC APIs?

  A. In a REST API, operations are performed on an object (node) that is identified by a URL, but RPC APIs are operation-oriented.
  B. In a REST API, operations are performed on an external resource that is defined on the API, but the RCP APIs are resource-oriented.
  C. In a REST API, operations are performed on a platform that is identified by the URL, but RPC APIs are platform-oriented.
  D. In a REST API, operations are performed on an internal resource that is defined on the API, but RPC APIs are resource-oriented.
  A. In a REST API, operations are performed on an object (node) that is identified by a URL, but RPC APIs are operation-oriented.

  ---

  REST APIs are designed around resources that are identified by URLs. Operations are performed on these resources using standard HTTP methods like GET, POST, PUT, and DELETE. In contrast, RPC (Remote Procedure Call) APIs are designed around actions or operations, where the focus is on invoking methods or functions rather than manipulating resources. Cisco DevNet Associate documentation on API design principles and differences between REST and RPC APIs.

  B. load balancer
  C. central switch
  D. default gateway
  D. default gateway

• Question 429:
