Sample H12-891_V1.0 Questions
Practice with real exam-style questions. Reveal answers to verify your knowledge.
Which of the following statements is correct about the differences between NSR and NSF?
As shown in the figure, ARP broadcast suppression is enabled on VTEP1 in BD 20 (VNI 200).
VTEP1 learns ARP information about PC2 through BGP EVPN routes.
When VTEP1 forwards the ARP request for PC1's MAC address to VTEP2,
What is the destination MAC address of the inner data frame?
In 6PE networking, the shared explicit null label function can be enabled on routers to reduce the number of required MPLS labels. With this function, a router assigns a label with the value (enter only digits) to all 6PE routes.
0In 6PE (IPv6 over MPLS for Provider Edge), the shared explicit null label value is 0. When this function is enabled, the PE router assigns label 0 (IPv4 Explicit Null) to all IPv6 routes, reducing the label space consumption. This is known as label 0 reuse for IPv6 forwarding over MPLS.Exact Extract - HCIE-Datacom IPv6/MPLS Integration Section:''To optimize label usage in 6PE deployments, shared explicit null label (label 0) can be assigned to all 6PE routes.''
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
