Cisco 200-901 Online Access

The Cisco DevNet Sandbox is a resource provided by Cisco that allows developers to access a variety of Cisco products in a development lab environment. This resource enables users to explore, learn, and build applications using Cisco APIs. The sandbox environment is equipped with pre-configured topologies and a range of Cisco technologies, offering a safe and secure space to experiment without the need for physical hardware.

DevNet Sandbox: Provides access to virtual environments for learning and development.

DevNet Communities: Are for discussions and collaboration among developers.

DevNet Code Exchange: Offers code repositories and examples for various Cisco technologies.

DevNet Automation Exchange: Focuses on automation scripts and tools shared by the community.

A routing table contains critical information used by routers to determine the best path for forwarding packets. The essential details included in a routing table are:

Destination network: The IP address of the destination network.

Next hop: The IP address of the next hop router or the outgoing interface to reach the destination network.

Metric: The cost associated with the path to the destination network, used to select the best route.

Route type: The type of route (e.g., directly connected, static, dynamic).

The YANG module shown in the exhibit is for interface management. It augments the ietf-interfaces module and defines parameters specific to Ethernet interfaces, such as auto-negotiation, duplex mode, and speed. This module is designed to manage the configuration and operational state of Ethernet interfaces. References for YANG modules can be found in the IETF YANG Data Model for Interface Management.

The HTTP status code 400 (Bad Request) is used by a REST API to indicate that the server cannot or will not process the request due to something that is perceived to be a client error (e.g., malformed request syntax, invalid request message framing, or deceptive request routing).
