• Question 32:

  A resource named /item is protected by oAuth2 authentication. An endpoint named /login must request authentication. Which method must be used to access the resource by using the REST API?

  A. Make a GET call to /login that includes the username and password, and retrieve a token to insert into the /item call.
  B. Make a POST call to /login including the user credentials in the message, and retrieve a token to insert into the authorization header of the /item call.
  C. Make a GET call to /item, then make a call to /login that includes the username and password in the body of the message, and wait for the authorization code.
  D. Make a POST call to /item that includes the username and password in the body of the request message, and submit it to request access.
  B. Make a POST call to /login including the user credentials in the message, and retrieve a token to insert into the authorization header of the /item call.

  When using OAuth2 authentication for accessing a protected resource via a REST API, the typical flow involves obtaining an access token which can then be used to authenticate subsequent API requests. The correct process is: POST Call to /login: Make a POST request to the /login endpoint with the user credentials (username and password) in the request body. This call will authenticate the user and, if successful, return an access token. Use the Token: Use the retrieved token by including it in the Authorization header (usually as a Bearer token) in the request to access the protected resource, in this case, the /item endpoint.

• Question 33:

  A company is adopting DevOps as part of an internal transformation, and is reviewing the success of the first deployments. Developers and engineers are working together to resolve any resulting issues. However, this new way of working has increased overhead, and the team is finding it difficult to complete releases in time. Which area of the CALMS framework must the company target for improvement?

  A. Collaboration
  B. Lean
  C. Sharing
  D. Measurement
  B. Lean

  ---

  The company is having difficulty with the "Lean" aspect of the framework. Lean principles focus on maximizing efficiency and minimizing waste in order to improve the speed and quality of software development and delivery.

• Question 34:

  Refer to the exhibit.

  

  A Cisco Meraki network was recently installed. Which TCP port is used to gain access to the Meraki dashboard to complete the configuration?

  A. 22
  B. 23
  C. 443
  D. 8080
  C. 443

• Question 35:

  What is a characteristic of Waterfall compared to Agile software development method?

  A. Waterfall focuses on continuous improvement, and Agile focuses on the design phase.
  B. Waterfall separates the project development lifecycle into sprints, and Agile does not use cycles.
  C. Waterfall specifies requirements before development begins, and Agile responds flexibly to changes in requirements.
  D. Waterfall uses reviews with step by step approach, and Agile uses a serially phased approach.
  C. Waterfall specifies requirements before development begins, and Agile responds flexibly to changes in requirements.

  ---

  The Waterfall model is a linear and sequential approach to software development. In Waterfall, all requirements are specified at the beginning of the project, and each phase (e.g., design, implementation, testing) must be completed before moving on to the next. This makes it less adaptable to changes once the project is underway. Agile, on the other hand, is an iterative approach that allows for flexible responses to changes in requirements. Agile development is organized into small, incremental cycles called sprints, which typically last 1-4 weeks. During each sprint, a small portion of the project is developed, and changes can be incorporated based on feedback and evolving requirements. Reference: Cisco DevNet Agile vs. Waterfall

• Question 36:

  What is the purpose of a MAC address?

  A. to uniquely identify a switch in a LAN
  B. to uniquely identify a router in a LAN
  C. to uniquely identify a network interface in a LAN
  D. to uniquely identify a device on the Internet
  C. to uniquely identify a network interface in a LAN

• Question 38:

  What is an advantage of using network programmability?

  A. Manual configuration is faster.
  B. No cloud abstraction occurs.
  C. It removes CLI access for devices.
  D. It provides for more scalable and replicable network provisioning.
  D. It provides for more scalable and replicable network provisioning.

• Question 39:

• Question 40:

  An engineer is creating an API to automatically obtain specific zones from Cisco Meraki MV cameras. The data that is provided when the API runs must represent the current analytic zones that are configured on the cameras. The API must start automatically at 6 p.m. every day and save the data on a server for further processing. Which part of the HTTP request must be configured to meet these requirements?

  A. request body with Status Code set to "302"
  B. request body with Content-Type set to "application/xml"
  C. request header with Content-Type set to "application/json"
  D. request header with Content-Encoding set to "application/xml"
  C. request header with Content-Type set to "application/json"

  ---

  When creating an API to interact with Cisco Meraki MV cameras, the request header must specify the correct content type to ensure the server understands the format of the request data. Setting the Content-Type header to "application/json" indicates that the request body is formatted as JSON. This is essential for APIs that expect JSON data for requests and responses. Additionally, the API must be scheduled to run automatically at 6 p.m. every day. This can be achieved using a cron job or a scheduling tool like cron in Unix-based systems or Task Scheduler in Windows.
