At ValidExamDumps, we consistently monitor updates to the Cisco 200-901 exam questions by Cisco. Whenever our team identifies changes in the exam questions,exam objectives, exam focus areas or in exam requirements, We immediately update our exam questions for both PDF and online practice exams. This commitment ensures our customers always have access to the most current and accurate questions. By preparing with these actual questions, our customers can successfully pass the Cisco DevNet Associate Exam exam on their first attempt without needing additional materials or study guides.
Other certification materials providers often include outdated or removed questions by Cisco in their Cisco 200-901 exam. These outdated questions lead to customers failing their Cisco DevNet Associate Exam exam. In contrast, we ensure our questions bank includes only precise and up-to-date questions, guaranteeing their presence in your actual exam. Our main priority is your success in the Cisco 200-901 exam, not profiting from selling obsolete exam questions in PDF or Online Practice Test.
What are two characteristics of Bare Metal environments that are related to application deployment? (Choose two.)
Bare Metal environments refer to physical servers that run directly on the hardware without a hypervisor. They offer several characteristics related to application deployment:
Provide workloads with access to hardware features: Bare Metal environments allow applications to directly access hardware resources, which can be critical for performance-sensitive applications.
Suitable for legacy applications that do not support virtualization: Some older applications may not be compatible with virtualized environments or may require direct access to physical hardware, making Bare Metal servers an ideal choice.
Bare Metal environments: Offer direct hardware access and are suitable for certain legacy applications.
Not specifically designed for container-based workloads: While containers can run on Bare Metal, these environments are not specifically tailored for containers.
Not providing hypervisors: Bare Metal environments do not include a hypervisor layer, which is a feature of virtualized environments.
An engineer must run tests on several Cisco controllers. Due to the nature of the task, the infrastructure must be running at all times and have access to APIs. Which Cisco DevNet source must the engineer use?
The Cisco DevNet Sandbox provides a virtual environment where engineers and developers can access and run tests on various Cisco controllers and infrastructure components. This service offers always-on and reservation-based sandboxes that simulate real-world environments.
DevNet Sandbox: The Sandbox offers various environments with preconfigured Cisco devices and APIs, allowing engineers to run tests and develop solutions without affecting live systems.
Always-On Sandboxes: These environments are always available and can be used without reservation.
API Access: The Sandbox environments include access to APIs, enabling comprehensive testing and integration.

A company requires a new platform to store large volumes of log data that is generated in their assembly plant. The platform must be scalable, so the underlying technology must provide a path for fast deployment of new nodes for data and indexing? The data contains sensitive information, so specialist encryption tools must be used to secure the dat
a. Which application deployment model meets the requirements?
A hybrid cloud deployment model combines elements of both private and public clouds, providing the scalability needed for fast deployment of new nodes for data and indexing. It allows for sensitive information to be stored in a private cloud where specialist encryption tools can be used, while non-sensitive data can be stored in the public cloud to take advantage of its scalability and cost benefits. This approach meets the requirements of both scalability and data security.
A REST API service requires authentication based on the username and password. The user ''john'' has the password ''384279060'' and the Base64 encoding of those credentials is ''am9objowMTIzNDU2Nzg=''. Which method completes an authentication request?
For Basic Authentication in REST APIs, the Base64 encoded credentials must be included in the header of the HTTP request. The correct method is to include the following header in the request:
Authorization: Basic am9objowMTlzNDU2Nzg=
What is the meaning of the HTTP status code 204?
The HTTP status code 204 means that the server has successfully processed the request, but there is no content to send in the response. This status code is typically used when the server fulfills the request, but no further information is needed to be returned to the client. The 204 status is used to indicate that the request was successful and that the client should not refresh or change the current page view. For example, this might be used when a form submission is processed without requiring any update to the client.
