NEW QUESTION # 48
In a scenario where a VXLAN tunnel is dynamically established through BGP EVPN, run the command on the VTEP to view BGP EVPN routes. The route entries shown in the following figure are displayed. Which of the following statements about these routing entries are correct?
Network (EthTagId/IP Prefix/IP PrefixLen)
NextHop
*>i 0:172.16.2.0:24 1.1.1.2
*>i 0:172.16.13.0:24 1.1.1.2
*>i 0:192.168.122.0:30 1.1.1.2
Answer: A,B
Explanation:
Understanding BGP EVPN Route Types for VXLAN
#BGP EVPN (Ethernet VPN) is used for VXLAN control-plane learning.
#EVPN Type 2 Route (MAC/IP Advertisement)
Carries:MAC + Host IP
Used for:L2 forwarding, Host Mobility
#EVPN Type 5 Route (IP Prefix Advertisement)
Carries:Network segment (Subnet) + Prefix
Used for:VXLAN L3 routing
#What Do the Given Route Entries Show?
0:172.16.2.0/24
0:172.16.13.0/24
0:192.168.122.0/30
#These are IPv4 Subnets, NOT individual MACs.
#Since they carry IP Prefixes, they belong to EVPN Type 5.
Analysis of the Answer Choices:
#A. These routes are Type 5 routes and carry network segment or mask information.
Correct:The displayed routescarry network prefixes, which belong toEVPN Type 5.
#B. These routes are Type 2 routes and carry host IP addresses.
Incorrect:Type 2 routescarry MAC + Host IP, NOT full subnets.
#C. These routes carry the L2VNI.
Incorrect:L2VNI is forLayer 2 VXLAN bridging, but these areIP Prefix Routes (L3 routing).
#D. These routes carry the L3VNI.
Correct:Type 5 routes are used forVXLAN L3 routing, which means they belong toL3VNI.
Real-World Application:
VXLAN L3 Gateways:Type 5 routes enabledistributed routing between VXLAN segments.
Data Center Networks:Used tointerconnect virtual machines (VMs) across different subnets.

NEW QUESTION # 49
If a router only needs to forward iPv6 packets, you do not need to configure any IPV4 agreements and addresses on that router.
Answer: B
NEW QUESTION # 50
A network administrator runs the display telemetry destination command on a device to check information about a destination group that sampled data is sent to. The command output is as follows. Which of the following statements is incorrect?
[~CE-telemetry-sensor-group-Sensor1]display telemetry destination
Dest-name Dest-addr Dest-port State Vpn-name Protocol
Dest1 192.168.56.1 20000 RESOLVED - GRPC
Answer: D
Explanation:
Understanding the Telemetry Output:
Dest-addr: 192.168.56.1 → The destination IP address is 192.168.56.1. ✅ Dest-name: Dest1 → The destination group name is Dest1. ✅ Protocol: gRPC → Data push uses the gRPC protocol. ✅ Vpn-name: - (empty) → No VPN encapsulation is used. ❌ Incorrect Answer
❌ C. "VPN encapsulation is used for data push" → Incorrect!
The Vpn-name field is empty, indicating that VPN encapsulation is NOT enabled for telemetry data transport.
