350-601 Network Practice Question
Which two statements correctly describe VXLAN BUM traffic handling? (Choose two.)
⚠ Common exam trap
Cisco often tests the misconception that multicast is mandatory for VXLAN BUM handling, but the exam expects you to know that ingress replication is a valid and commonly used alternative, especially in EVPN-based designs.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Ingress replication sends unicast copies of the BUM traffic to each remote VTEP.
In VXLAN, BUM traffic (Broadcast, Unknown unicast, Multicast) can be handled using ingress replication, where the ingress VTEP creates multiple unicast copies of the packet and sends them directly to each remote VTEP. This is the default mode in many VXLAN implementations, especially in EVPN-based fabrics, and does not require a multicast group in the underlay. Option A correctly describes this behavior.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Ingress replication sends unicast copies of the BUM traffic to each remote VTEP.
Why this is correct
Correct description.
- ✗
BUM traffic is dropped by default.
Why it's wrong here
BUM traffic must be handled for proper operation.
- ✓
Multicast group is used to distribute BUM traffic to all VTEPs that need it.
Why this is correct
Correct description.
- ✗
Ingress replication sends a single multicast packet to all VTEPs.
Why it's wrong here
Ingress replication sends unicast copies to each VTEP.
- ✗
Multicast is required for VXLAN BUM handling.
Why it's wrong here
Multicast is optional; ingress replication can be used.
