350-401 Question #325: Real Exam Question with Answer & Explanation

Question

Refer to the exhibit. What is required to configure a second export destination for IP address 192.168.10.1?

Options

• ASpecify a VRF.
• BSpecify a different UDP port.
• CSpecify a different flow ID
• DConfigure a version 5 flow-export to the same destination.
• ESpecify a different TCP port.

Explanation

Explanation

When configuring multiple NetFlow export destinations to the same IP address (192.168.10.1), the router requires a different UDP port number to differentiate between the two export streams, since NetFlow uses UDP as its transport protocol. Without a unique UDP port, the router cannot distinguish between the two destination configurations and will reject the duplicate entry.

Why the distractors are wrong:

• A (VRF): A VRF is used to separate routing instances/tables, not to distinguish multiple export destinations to the same IP.
• C (Flow ID): Flow IDs are not a configurable parameter used to differentiate NetFlow export destinations in this context.
• D (Version 5 flow-export): Adding a different NetFlow version to the same destination IP still requires a unique port; the version alone does not resolve the conflict.
• E (TCP port): NetFlow exports use UDP, not TCP, so specifying a TCP port is not applicable here.

Memory Tip 🧠

Think of it like sending two letters to the same building - the apartment number (UDP port) is what ensures each delivery reaches the right recipient. Same IP = same building; different UDP port = different apartment.
