Question
Refer to the exhibit. The network administrator is enabling network visibility on the edge router. The flow exporter must be leveraging an RFC 7011--based protocol, and data streams must be sent every 3 seconds. Which two commands must the administrator apply to complete the task?
Options
- Aexport-protocol netflow-v5
- Btemplate data timeout 3
- Cexport-protocol netflow-v9
- Dexport-protocol ipfix
- Etemplate data timeout 180

Why each option
The administrator must configure the flow exporter to use IPFIX, which is an RFC 7011-based protocol, and ensure data templates are sent every 3 seconds for timely network visibility.
NetFlow v5 is an older, fixed-format protocol and does not leverage the flexible template-based mechanism defined in RFC 7011 (IPFIX).
The 'template data timeout 3' command configures the router to export template data records every 3 seconds, which is essential for ensuring the collector has up-to-date information for parsing flow records.
NetFlow v9 is a flexible, template-based protocol but is not strictly RFC 7011; IPFIX (NetFlow v10) is the IETF standard based on RFC 7011.
The 'export-protocol ipfix' command configures the router to use IPFIX (IP Flow Information Export) as the export protocol, which is the standard based on RFC 7011.
Setting the 'template data timeout' to 180 seconds does not meet the requirement for data streams to be sent every 3 seconds.
