Implementing and Operating Cisco Security Core Technologies (SCOR) — Question 230

What is the most commonly used protocol for network telemetry?

Answer options

• A. NetFlow
• B. SNMP
• C. TFTP
• D. SMTP

Correct answer: A

Explanation

NetFlow is the most commonly used protocol for network telemetry as it provides detailed traffic analysis and monitoring capabilities. While SNMP is used for network management, it does not offer the same level of detail in traffic analysis as NetFlow. TFTP is primarily used for file transfer, and SMTP is used for email transmission, making them unsuitable for telemetry purposes.
