JNCIP-SP: Juniper Networks Certified Professional – Service Provider (2022) — Question 82

Which statement is correct about BGP FlowSpec between a service provider's PE router and a customer?

Answer options

• A. The flow routes received from a customer are limited to /32 masks for IPv4.
• B. The NLRI received from a customer is stored in the flowspec.inet.0 table.
• C. The RFC deterministic traffic filtering algorithm is used by default in Junos.
• D. The NLRI received from a customer is stored in the inetflow.0 table.

Correct answer: D

Explanation

The correct answer is D because the NLRI from a customer is indeed stored in the inetflow.0 table, which is specifically designated for FlowSpec routes. Option A is incorrect as FlowSpec can support more than just /32 masks, option B is wrong since the flowspec.inet.0 table is not where the NLRI is stored, and option C is misleading as the default algorithm is not RFC-based.
