What are two benefit of managing network configuration via APIs? (Choose two.)
Managing network configuration via APIs brings several benefits:
Increased Scalability and Consistency of Network Changes: APIs allow for programmatic control over network configurations, enabling automation of repetitive tasks. This leads to consistent configurations across devices and easier scalability as networks grow.
Reduction in Network Changes Performed Manually: Automation through APIs reduces the need for manual configuration, which decreases the likelihood of human error and increases overall efficiency. These advantages contribute to more reliable and manageable network operations. Reference: Cisco DevNet Associate Certification Guide, Chapter 3, Section on Network Automation and APIs.
Which advantage does the agile process offer compared to waterfall software development?
The agile process allows for incremental delivery of features, meaning new functionalities can be added or existing ones updated in small, manageable increments. This is in contrast to the waterfall model, where all phases are completed before the product is delivered. Agile enables continuous improvement and adaptation to changing requirements throughout the development process.
How are load balancers used in modern application deployment?
Load balancers distribute network or application traffic across multiple servers to ensure no single server becomes overwhelmed. In modern application deployment, load balancers allow traffic to continue smoothly as new compute units are brought online and old units are decommissioned. This ensures high availability and reliability of services.
Which HTTP status Code means that the server cannot or will not process the request because of perceived client error?
The HTTP status code 400 indicates that the server cannot or will not process the request due to a client error.
HTTP Status Code 400 - Bad Request:
Meaning: The server cannot process the request due to a client-side error. This could be due to malformed request syntax, invalid request message framing, or deceptive request routing.
Common Causes: Typical reasons for a 400 Bad Request include incorrect URL formatting, invalid query parameters, or unsupported characters in the request.
Client Error Category: Status codes in the 4xx range indicate client errors, where the problem lies with the request sent by the client rather than the server.
Other Status Codes:
100 - Continue: Informational status code indicating that the initial part of a request has been received and the client can continue with the rest of the request.
203 - Non-Authoritative Information: The server successfully processed the request, but the information may come from a different source.
303 - See Other: The server is redirecting the client to a different resource, typically using the GET method.

Which two descriptions can be given to an application that is interacting with a webhook? (Choose two.)
In the context of webhooks, an application that interacts with a webhook can be described as a Listener or Receiver:
Listener: The application waits for incoming HTTP POST requests sent by the webhook.
Receiver: The application receives the data payloads from the webhook when certain events occur.
