300-435 Question 79
Single answerYou are tasked with automating the configuration of multiple IOS XE devices in your network. To ensure secure access, you need to retrieve operational data from the devices using a programmatic interface. Which protocol should you use for this purpose?
- A
NETCONF
- B
Telnet
- C
HTTP
- D
SNMP
Show answer and explanation
Correct answer: A
Explanation
NETCONF is the correct protocol to use when automating IOS XE devices for retrieving operational data and managing configurations. It is secure, extensible, and well-suited for modern network automation workflows, making it the preferred choice over older protocols like Telnet or SNMP.
- A. Correct.
NETCONF is a protocol designed for managing and retrieving configuration and operational data from devices like Cisco IOS XE. It supports secure communication using SSH.
- B. Incorrect.
Telnet is an older protocol that does not provide secure communication and is not suitable for modern programmatic automation tasks.
- C. Incorrect.
HTTP is primarily used for web-based communication and is not optimized for retrieving operational data or managing configurations on network devices.
- D. Incorrect.
SNMP is a protocol for network management that retrieves operational data but is not as robust or secure as NETCONF for automation tasks.
