質問 # 169
A recent set of changes by a Cisco ACI administrator corrupted the APIC cluster. The ACI engineer must restore the configuration of the previous day. The APIC nodes in the cluster can communicate but fail to connect with other networks. The administrator plans to overwrite the entire existing configuration with the backup configuration. Which set of actions accomplishes this task?
- A. Roll back the configuration using a local snapshot.
Use an import policy set to Atomic Replace. - B. Roll back the configuration using a local snapshot.
Use an import policy set to Best-effort Merge. - C. Restore using the last configuration on the factory-reset APIC.
Use an import policy set to Best-effort. - D. Restore the configuration imported from an FTP server.
Use an import policy set to Atomic.
正解：A
解説：
Atomic Replace - overwrites existing configuration with imported configuration data. Any objects in the existing configuration that do not exist in the imported configuration are deleted. Objects are deleted from the existing configuration that have children in the existing configuration but do not have children in the incoming imported configuration. For example, if an existing configuration has two tenants, solar and wind, but the imported backed up configuration was saved before the tenant wind was created, tenant soar is restored from the backup but tenant wind is deleted.

Untagged VLAN Access: selected
VLAN Mode: Static with Encap: 100 - C. Define a static VLAN range (from 100-200) under a VLAN pool that is associated with the dc1vcdev domain.

- C. limit IP learning to subnet
- D. subnet control
正解：C
質問 # 177
Refer to the exhibit.
An engineer is integrating a VMware vCenter with Cisco ACI VMM domain configuration. ACI creates port-group names with the format of "Tenant | Application | EPG". Which configuration option is used to generate port groups with names formatted as "Tenant=Application=EPG"?
- A. security domains
- B. delimiter
- C. enable tag collection
- D. virtual switch name
正解：B
質問 # 178
Refer to the exhibit.
Refer to the exhibit. A Cisco ACI environment hosts two e-commerce applications. The default contract from a common tenant between different application tiers is used, and the applications work as expected. The customer wants to move to more specific contracts to prevent unwanted traffic between EPGs. A network administrator creates the app-to-db contract to meet this objective for the application and database tiers. The application EPGs must communicate only with their respective database EPGs. How should this contract be configured to meet this requirement?
- A. Implement the app-to-db scope as VRF.
- B. Implement the app-to-db as a Taboo contract.
- C. Set the app-to-db scope to Application Profile.
- D. Set the app-to-db scope to Global.
正解：B
質問 # 179
Where is the COOP database located?
- A. APIC
- B. endpoint
- C. leaf
- D. spine
正解：D
質問 # 180
An engineer configured a bridge domain with the hardware-proxy option for Layer 2 unknown unicast traffic. Which statement is true about this configuration?
- A. The spine switch drops the Layer 2 unknown unicast packet if it is unable to find the MAC address in the proxy database.
- B. The leaf switch forwards the Layers 2 unknown unicast packets to all other leaf switches if it is unable to find the MAC address in its local forwarding tables.
- C. The Layer 2 unknown hardware proxy lacks support of the topology change notification.
- D. The leaf switch drops the Layer 2 unknown unicast packet if it is unable to find the MAC address in the local forwarding tables.
正解：A
解説：
When using hardware-proxy, you should consider enabling unicast routing and defining a subnet on the bridge domain. This is because with hardware-proxy on, if a MAC address has been aged out in the spine switch-proxy, traffic destined to this MAC address is dropped.
