Cisco DNA Center provides a REST API that allows users to interact with the network devices managed by the platform. To retrieve a list of network devices, an HTTP GET request is sent to the endpoint https://DNA-c_API_ADDRESS/api/v1/network-device/ . The response from this request contains a list of network devices in JSON format. This API endpoint allows for programmatic access to network device data, facilitating automation and integration with other systems. Detailed information about the Cisco DNA Center APIs can be found in the Cisco DNA Center API documentation.

When converting XML to JSON, the structure should maintain the hierarchical organization and data representation. The provided XML structure:

10.00

9.00

8.00

20.00

12.00

translates to the following JSON structure:

{

"books": {

"science": {

"biology": "10.00",

"geology": "9.00",

"chemistry": "8.00"

},

"math": {

"calculus": "20.00",

"algebra": "12.00"

}

}

}

Root Element: The root element translates to a key "books".

Nested Elements: The and $elements\; become\; nested\; objects\; under\; "books".$

Leaf Elements: The individual subjects and their prices (e.g., 10.00) become key-value pairs within their respective parent objects.

Option A:

json

Copy code

{

"books": {

"science": {

"biology": "10.00",

"geology": "9.00",

"chemistry": "8.00"

},

"math": {

"calculus": "20.00",

"algebra": "12.00"

}

}

}

This option accurately represents the hierarchical structure of the XML data, making it the correct equivalent.

Option B, C, and D:

These options incorrectly use array notation for the nested objects, which is not consistent with the original XML structure. The XML structure indicates that "science" and "math" are single objects with multiple key-value pairs, not arrays.

Edge computing is a distributed computing paradigm that brings computation and data storage closer to the sources of data. This helps to:

Reduce Latency: By processing data closer to where it is generated, edge computing reduces the time taken for data to travel to a central server and back. This is especially important for applications requiring real-time or near-real-time responses.

Optimize Bandwidth: Reducing the amount of data sent to a central data center can conserve bandwidth and lower costs.

Enhance Security and Privacy: Processing data locally can enhance security and privacy by minimizing the exposure of data during transmission.

When you execute the command git clone ssh://john@example.com/path/to/my-project_git, the git clone command is used to create a local copy of a remote repository. In this case, it is accessing the repository over SSH (Secure Shell). The URL ssh://john@example.com/path/to/my-project_git specifies the location of the remote repository.

git clone is a Git command that creates a copy of an existing repository in a new directory.

The local copy will contain all the history and branches of the original repository.

The repository will be cloned into a directory named after the remote repository, which in this case would be "my-project".

Injection attacks occur when untrusted data is sent to an interpreter as part of a command or query. The attacker's hostile data can trick the interpreter into executing unintended commands or accessing data without proper authorization. Common types of injection attacks include SQL injection, command injection, and LDAP injection. These types of attacks exploit vulnerabilities in how an application processes input data, allowing attackers to inject malicious commands or queries into the system.

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).
