A. B. C. D.A.
The correct answer is D. record mpls ipv6-fields labels.
Explanation: NetFlow is a feature that provides network administrators with the ability to collect IP network traffic as it enters or exits an interface on a router or switch. NetFlow can be used for a variety of purposes, such as network performance monitoring, security analysis, and capacity planning.
In the case of MPLS traffic with an IPv6 payload, the NetFlow monitor configuration needs to include a specific record statement that instructs the router or switch to collect the relevant information. The record statement specifies the fields that should be included in the NetFlow record.
The record mpls ipv6-fields labels statement is used to collect MPLS traffic with an IPv6 payload. This statement tells the router or switch to include the MPLS label stack information in the NetFlow record, as well as the IPv6 fields.
Option A, record mpls IPv6-fields labels 3, is incorrect because it includes an extra parameter 3. The 3 is not a valid parameter for this statement.
Option B, record mpls IPv4-fields labels 3, is incorrect because it specifies IPv4 fields instead of IPv6 fields.
Option C, record mpls labels 3, is incorrect because it does not specify whether IPv4 or IPv6 fields should be included in the NetFlow record.
