Quick Answer
The answer is Type-2 (MAC/IP Advertisement), Type-3 (Inclusive Multicast Ethernet Tag), and Type-5 (IP Prefix Advertisement). These three EVPN route types are essential for VXLAN EVPN operation because they handle the core data plane functions: Type-2 routes advertise host MAC and IP addresses to enable Layer 2 forwarding and ARP suppression, Type-3 routes enable BUM traffic replication by mapping VNIs to multicast groups so VTEPs join the correct underlay tree, and Type-5 routes advertise external IP prefixes for inter-subnet routing without requiring a separate gateway protocol. On the Cisco DCCOR 350-601 exam, this question tests your understanding of which route types are mandatory for a typical VXLAN EVPN fabric, often appearing as a multi-select item. A common trap is including Type-1 (Ethernet Auto-Discovery) or Type-4 (Ethernet Segment), which are only needed for multihoming or redundancy, not basic operation. Remember the mnemonic “2-3-5 for the basic drive”—these three keep the fabric alive.
This 350-601 practice question tests your understanding of network. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which three EVPN route types are essential for VXLAN EVPN operation in a typical data center fabric? (Choose three.)
Type-3 (Inclusive Multicast Ethernet Tag)
Required for BUM traffic forwarding.
Type-2 (MAC/IP Advertisement)
Required for host reachability.
Type-4 (Ethernet Segment)
Why wrong: Used for multi-homing, not essential for basic fabric.
Type-5 (IP Prefix Advertisement)
Required for exchanging IP prefixes.
Type-1 (Ethernet Auto-Discovery)
Why wrong: Used for multi-homing, not essential for basic fabric.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Type-3 (Inclusive Multicast Ethernet Tag)
Type-3 (Inclusive Multicast Ethernet Tag) routes are essential for VXLAN EVPN because they enable BUM traffic replication across the underlay network by advertising the VNI and multicast group mapping, allowing VTEPs to join the correct multicast tree for flooding unknown unicast, broadcast, and multicast frames.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Cisco often tests the misconception that Type-1 and Type-4 are required for all VXLAN EVPN deployments, but they are only mandatory for multi-homing (EVPN-MH) or MPLS interworking, not for a typical single-homed data center fabric.
Detailed technical explanation
Under the hood, Type-3 routes carry the Route Distinguisher (RD), VNI, and multicast group address (or ingress-replication list) in the Network Layer Reachability Information (NLRI). In a typical fabric without multicast, Type-3 routes can signal ingress replication endpoints, but the core requirement remains that every VTEP must learn the VNI-to-VTEP mapping via Type-3 to handle BUM traffic correctly. Type-2 routes carry MAC and IP addresses with VNI and next-hop VTEP, enabling host reachability and ARP suppression. Type-5 routes advertise IP prefixes (e.g., external subnets) with VNI, allowing inter-VRF and external routing without MAC lookup.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A network engineer segments a warehouse floor into three subnets: 20 scanners, 5 printers, and 2 management hosts. Picking the wrong mask wastes addresses or leaves too few usable hosts. Exam questions test whether you can apply CIDR notation, calculate block size, and identify the correct usable-host range for a given prefix.
