100% Cisco 350-901 Guaranteed Success With Testing Engine

Breaking Down the Key Knowledge Areas of 350-901

Cisco 350-901 DEVCOR is a 120-minute exam that can be taken at Pearson VUE testing centers or online. Here's what you should know to pass it hassle-free:

• Cisco platforms

  This section will assess your ability to construct API requests for implementing chatops with Webex Teams API, API requests for creating and deleting objects with the Firepower Device Management (FDM), and API requests for retrieving data from Intersight. Also, the questions under this section confirm if you understand AppDynamics and its capabilities, the construction of a Python script with the Cisco DNA center APIs for retrieving and displaying wireless health information, and Cisco DNA center APIs.

• Software development and design

  This domain includes the concepts such as application design concerning scalability, modularity, resiliency, observability, and high availability. Also, the candidates will be expected to explain release packaging and dependency management principles, architectural patterns, and distributed applications. Finally, learners should know how to use advanced version control operations with Git and understand the construction of a sequence diagram that accommodates API calls.

• Security and application deployment

  The topics included in this domain cover the principles of end-to-end encryption, defining the secret storage approach, the use of Docker for containerizing an app, and diagnosing a CI/CD pipeline failure. Finally, the candidates have to understand the benefits of static code analysis as well as continuous testing, know effective strategies for logging, and more.

• Using APIs

  This topic requires mastery of the implementation of robust REST API error handling, skills in applying the control flow of consumer code as far as unrecoverable REST API errors are involved, and the ability to define possible approaches for optimizing API usage using cache controls. What's more, this domain will also confirm if you understand the OAuth2 concepts.

• Automation and infrastructure

  This section is focused on the areas such as model-driven telemetry, setting up network parameters by constructing certain workflows, and the use of RESTCONF. Also, one should understand how to host an app on a network device and how to select the most appropriate configuration management solution.

Cisco 350-901 Exam Syllabus Topics:

Cisco Developing Applications using Cisco Core Platforms and APIs (DEVCOR) Sample Questions:

Question #1
Drag and Drop Question
Drag and drop the code from the bottom onto the box where the code is missing to deploy three Cisco UCS servers, each from a different template. Not all options are used.

Question #2
Refer to the exhibit. A network automation solution is being constructed to integrate inventory data using a workflow orchestrator for orchestration and a REST API service as the source of the data. The infrastructure team organized variable files for device management. When building the integration workflow, which action must be taken to ensure that the orchestration layer can reliably access the inventory data from the designated system?

A. Use a configuration lookup.
B. Configure an HTTP connection.
C. Declare a static variable set.
D. Update a template filter.

Question #3
A development team is preparing to deploy a next-generation network architecture for an organization that wants to improve efficiency. The team is evaluating various solutions because zero-touch provisioning capability is required for the project, and the timeline demands rapid implementation. After the project needs are discussed, the organization decides to prioritize visual workflow design. Which technology meets the network automation needs of the deployment?

A. high-performance virtual network appliance
B. centralized traffic monitoring dashboard
C. drag-and-drop automation platform
D. encrypted traffic analysis engine

Question #4
Which authorization steps are required to obtain an access token according to the OAuth2 authorization code grant flow?

A. Log in with a username and password using a form, get a token, and include the token in the body.
B. Send the base64 encoded username, password, client ID, and client secret to the single sign-on manager.
C. Authenticate, get the authorization code, and send it with the client ID and client secret.
D. Send the client ID and client secrets by using the grant flow type, get the token, and authorize by using a callback.

Question #5
A company must adopt a configuration management solution for its multi-cloud microservices architecture. The solution has these requirements:
- Hybrid cloud deployment
- Automated compliance and security configurations
- Dynamic infrastructure scaling
- Zero-downtime updates
- Immutable infrastructure principles
- Advanced configuration monitoring
Which configuration management solution should be implemented?

A. Ansible playbooks with dynamic inventory
B. custom Python infrastructure scripts
C. Terraform with multi-cloud state management
D. Chef-based configuration management
