B. Cisco XCP Router
C. Cisco Presence Engine
D. Cisco XCP SIP Federation Connection Manager

Configure the Routing Node
For multi-node chat-only deployments, choose an IM and Presence Service cluster node to act as the routing node. To provide extra capacity for routing, there should be no users assigned to the routing node. The routing node acts as a front- end server, accepting inbound SIP requests from Lync/OCS and routing those requests to the appropriate cluster node that homes the recipient.
Note For chat+calling deployments with Lync, and for single-node deployments, you can skip this procedure as there is no need to configure a routing node.
Step 1 From the Cisco Unified IM and Presence Serviceability user interface, choose Tools > Service Activation.
Step 2 From the Server drop-down menu, choose the cluster node that you want to designate as the routing node. The routing node should have no users assigned.
Step 3 Check the Cisco SIP Proxy feature service.
Step 4 Uncheck the following feature services:
Cisco Presence Engine
Cisco XCP Text Conference Manager
Cisco XCP Web Connection Manager
Cisco XCP Connection Manager
Cisco XCP SIP Federation Connection Manager
Cisco XCP XMPP Federation Connection Manager
Cisco XCP Message Archiver
Cisco XCP Directory Service
Cisco XCP Authentication Service
Step 5 Click Save.
Step 6 Confirm that the CIsco XCP Router network service is running. Because the service is a network service it is running by default, unless you previously disabled it.
Choose Tools > Control Center ¬ Network Services.
From the Server drop-down menu, select the routing node and click Go.
If the CIsco XCP Router service is not running, check the corresponding radio button, and click Star

You consider using RPL in a new loT environment. Which definition of a DIO is true?
A. A DIO is an ICMPv6 RPL control message whose main function is to perform DODAG secure message counters
B. A DIO is an ICMPv4 RPL control message whose main function is to perform DODAG discovery, formation, and maintenance
C. A DIO is an ICMPv6 RPL control message whose main function is to perform DODAG discovery, formation, and maintenance
D. A DIO is an ICMPv4 RPL control message whose main function is to propagate destination information in a RPL network
RPL messages are carried via ICMPv6 message. The following messages are available:
DAG Information Solicitation (DIS)
DAG Information Object (DIO)
Destination Advertisement Object (DAO)
RPL DIO messages are sent for DODAG discovery and maintenance. DIO are multicasted according to trickle timers. DIO messages are used for DODAG discovery and maintenance.
Use the dao solicit-interval command to configure the frequency (in minutes) at which the root can solicit destination advertisement messages from the downstream nodes. The mode of operation setting is specified as part of instance ID definition. You can also increment the version number using the version-number version keyword argument pair in the rpl command.
