質問 22
An engineer has set the VMM resolution immediacy to pre-provision in a Cisco ACI environment. No Cisco Discovery Protocol neighborship has been formed between the hypervisors and the ACI fabric leaf nodes. How does this affect the download policies to the leaf switches?

- B. Policies are downloaded when the hypervisor host is connected to the VMM VDS.
- C. Policies are downloaded to the ACI leaf switch regardless of Cisco Discovery Protocol neighborship.
- D. No policies are downloaded because there is no discovery protocol neighborship.

質問 26
Refer to the exhibit.
A systems engineer is implementing the Cisco ACI fabric. However, the Server2 information is missing from the Leaf 101 endpoint table and the COOP database of the spine. The requirement is for the bridge domain configuration to enforce the ACI fabric to forward the unicast packets generated by Server1 destined to Server2. Which action must be taken to meet these requirements?
- A. Set L2 Unknown Unicast to Flood
- B. Enable Unicast Routing
- C. Enable ARP Flooding
- D. Set IP Data-Plane Learning to No
正解: A
解説:
Both servers are in the same subnet. ARP flooding is out if we read the article in the link. Also unicast routing is not needed.
