Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) — Question 126

Which additional configuration is required for NetFlow to provide traceback information?

Answer options

• A. A classification ACL must be configured to identity which type of traffic will be analyzed.
• B. The BGP routing process must be started for any ingress or egress data to be reported when using NetFlow Version 5.
• C. Cisco Express Forwarding must be configured for traffic that is egressing from the router to be property reported.
• D. LLDP must be configured or the device will be unable to locate a NetFlow analyzer.

Correct answer: A

Explanation

The correct answer is A because a classification ACL is essential for identifying the specific traffic to be analyzed for traceback. The other options, while related to NetFlow, do not pertain directly to the requirement for traceback information; B discusses BGP, C mentions Cisco Express Forwarding for egress traffic reporting, and D addresses LLDP configuration, which does not influence NetFlow traceback capability.
