質問 1：
A QFabric system continuously drops Layer 3 inter-VLAN routed traffic. Host 1 is connected to SNG-1 on VLAN 10 and Host 2 is connected to SNG-2 on VLAN 20. You determine that SNG-1 does not have the ARP entry for Host 2, but the ARP entry is present on the network Node group.

A. SNG-1 is not receiving the host route from the fabric control Routing Engines.
B. The Node devices connecting to Host 2 and Host 1 are not part of the same redundant server Node group.

Host A on the Node device LC1 is not able to connect to Host B on the Node device LC0.The MAC address of Host A is 00:05:33:64:c6:a9. The MAC address of Host B is 00:05:33:64:c0:a5.
Referring to the exhibit, what is causing this problem?
A. The fabric route table on the fabric control Routing Engine does not have MAC address of Host A.
B. Hosts A and B are on different VLANs.
C. The fabric control Routing Engine is not advertising the MAC address of Host B to the Node device LC1.
D. The fabric manager Routing Engine has not learned the MAC addresses from both Node devices.
正解：C
