Selected 200-901 Cisco Certified DevNet Associate Questions Answers

DevOps emphasizes collaboration between development and operations teams, breaking down organizational silos to improve workflow and communication (C). Additionally, DevOps focuses on automating processes to increase efficiency, reduce manual effort, and minimize errors, often prioritizing automation over extensive documentation (E).

Option A correctly creates a handle instance using the UcsHandle class from the UCS SDK in Python. The correct instantiation requires providing the IP address, username, password, port number, and secure connection parameters as per the documented API.

The correct code snippet is:

from ucsmsdk.ucshandle import UcsHandle

handle = UcsHandle("10.1.2.254", "admin", "password", port="443", secure=True)

This snippet matches the API documentation requirements:

ip: The IP or hostname of the UCS Server.

username: The username as configured on the UCS Server.

password: The password as configured on the UCS Server.

port: The port number to be used during the connection.

secure: True for a secure connection.

========================

The error message "JSON-PARSE-ERROR" and "Unexpected character ('"' (code 34))" indicates a problem with the formatting of the JSON payload. Specifically, there are likely incorrect characters or misplaced quotes within the JSON structure. JSON formatting issues are common errors that can occur due to syntax mistakes such as missing commas, incorrect braces, or invalid characters.

To resolve this, carefully check the JSON structure for proper formatting, ensuring all fields are correctly defined and that syntax rules are followed.

The YANG structure shown defines a leaf IPPeer that can be either an IPv4 address or an IPv6 address. The third JSON example correctly represents this union type by using an array with both possible types included:

"IPPeer": [

"10.1.1.1",

"2001:db::1"

]

}

This correctly reflects the YANG definition, where IPPeer can be either type specified in the union.
