Answer: A
Explanation:
http://aci-troubleshooting-book.readthedocs.io/en/latest/rest.html
http://www.cisco.com/c/en/us/td/docs/unified_computing/ucs/ucs-director/rest-api-getting-started-guide/5-4/b_REST_API_Getting_Started_Guide_54.html
Write Operations
Create and update operations to the REST API are actually both implemented using the POST method, so that if an object does not already exist it will be created, and if it does already exist, it will be updated to reflect any changes between its existing state and desired state.
Both create and update operations can contain complex object hierarchies, so that a complete tree can be defined within a single command, so long as all objects are within the same context root and they are under the 1MB limit for data payloads to the REST API. This limit is in place to guarantee performance and protect the system under high load.
QUESTION 10

Distributing NTP Using CFS
Cisco Fabric Services (CFS) distributes the local NTP configuration to all Cisco devices in the network.
After enabling CFS on your device, a network-wide lock is applied to NTP whenever an NTP configuration is started. After making the NTP configuration changes, you can discard or commit them.
In either case, the CFS lock is then released from the NTP application.
QUESTION 16
Which two guidelines and limitations of netflow on Cisco NX-OS are true? (Choose 2)

Answer: DE
Explanation:
http://www.cisco.com/c/en/us/td/docs/switches/datacenter/sw/5_x/nx-os/system_management/configuration/guide/sm_nx_os_cg/sm_15netflow.html#wp1088665
Guidelines and Limitations
NetFlow has the following configuration guidelines and limitations:
•You must configure a source interface. If you do not configure a source interface, the exporter will remain in a disabled state.
•You must configure a valid record name for every flow monitor.
•A rollback will fail if you try to modify a record that is programmed in the hardware during a rollback.
•Only Layer 2 NetFlow is applied on Layer 2 interfaces, and only Layer 3 NetFlow is applied on Layer 3 interfaces.
•If you add a member to a port channel that is already configured for Layer 2 NetFlow, its NetFlow configuration is removed and the Layer 2 configuration of the port channel is added to it.
•If you change a Layer 2 interface to a Layer 3 interface, the software removes the Layer 2 NetFlow configuration from the interface.
•Use v9 export to see the full 32-bit SNMP ifIndex values at the NetFlow connector.
•The maximum number of supported NetFlow entries is 512K.
•The Cisco Nexus 2000 Series Fabric Extender supports bridged NetFlow.
•Beginning with Cisco NX-OS Release 5.2, NetFlow is supported on switch virtual interfaces (SVIs) for F1 Series ports. Bridged NetFlow on F1 Series ports is not supported.
