Ansible is a configuration management tool that has agentless capabilities. It uses SSH for communication and does not require any agent software to be installed on the managed nodes. This simplifies management and reduces overhead.

The DevNet Automation Exchange is designed to provide users with easy-to-consume use cases for network automation across various skill levels. It includes resources for beginner, intermediate, and advanced users to help them accelerate the adoption of automation technologies.

DevNet Automation Exchange: This site provides curated content and solutions for network automation. It includes code samples, learning labs, and use cases that cater to different skill levels.

User-Friendly Resources: The platform is designed to help users find relevant information quickly and easily, regardless of their experience level.

Option B is the correct answer because it specifically addresses the need for a single site that offers a variety of resources for different skill levels in network automation.

An IP (Internet Protocol) address is a unique identifier assigned to each device connected to a network that uses the IP for communication. It serves two main functions: identifying the host or network interface and providing the location of the host in the network. This unique ID allows devices to locate and communicate with each other over an IP-based network, ensuring that data sent across the network reaches the correct destination.

Model-driven programmability leverages models to represent the desired state of network configurations, allowing for programmatic and standards-based management. This approach ensures that configurations can be written consistently and automatically across different network devices, simplifying network management and reducing the risk of configuration errors.

The NETCONF RPC message shown in the exhibit requests the running configuration of the device filtered to show only interface names.

A. The running-config of the device is returned - Correct. The RPC message with the operation retrieves the running configuration filtered to include only the interface names. B. The name of each interface is reset to a default name - Incorrect. The RPC message is a read operation, not a configuration change. C. All the YANG capabilities supported by the device are returned - Incorrect. The RPC message specifically targets the running configuration, not the YANG capabilities. D. A list of interface names is returned - Incorrect. While the filter is for interface names, the context is that the running configuration containing these interface names is returned.

Organizing code into modules helps manage large and complex systems by breaking them down into smaller, more manageable pieces. Each module can be developed, tested, and maintained independently, which simplifies the overall development and maintenance process.

In the provided Python function enable_function, the parameters are if_name, if_status, and if_type, which correspond to the interface name, status (enabled/disabled), and interface type respectively.

Function Parameters: The function enable_function is designed to take three parameters: the interface name (if_name), the status (if_status), and the type (if_type).

Correct Order and Values: To enable the interface named "Loopback1", you need to pass the correct values in the order they are defined in the function.

Option A correctly calls the function with the interface name "Loopback1", the status true (enabled), and the interface type 'iana-if-type:softwareLoopback'.

A developer is creating a script to interact with a REST API service that requires basic authentication. The correct combination of payload and headers using Basic Authentication with the provided Base64 encoded credentials is:

A. This option does not use headers correctly. B. Option B - Correct. This option correctly places the 'Authorization' header in the headers dictionary with 'Basic' authentication. C. This option uses 'Bearer' instead of 'Basic' for the 'Authorization' header. D. This option uses 'Bearer' instead of 'Basic' for the 'Authorization' header.

A VLAN (Virtual Local Area Network) allows devices on one or more LANs to be grouped together as if they were on the same physical network, even if they are not.

Logical Segmentation: VLANs provide logical segmentation of networks, enabling devices to communicate as if they are on the same physical network.

Isolation and Flexibility: They offer isolation and flexibility in network design, improving security and reducing broadcast domains.

Option B is correct as VLANs create logical groupings of devices that communicate as if they are on the same physical LAN.
