Topic 2: Exam Pool B
Refer to the exhibit.
What is required to configure a second export destination for IP address 192.168.10.1?
A.
Specify a VRF.
B.
Specify a different UDP port.
C.
Specify a different flow ID
D.
Configure a version 5 flow-export to the same destination.
E.
Specify a different TCP port.
Specify a different UDP port.
Explanation: To configure multiple NetFlow export destinations to a router, use the following commands in global configuration mode:
Step 1: Router(config)# ip flow-export destination ip-address udp-port
Step 2: Router(config)# ip flow-export destination ip-address udp-port
The following example enables the exporting of information in NetFlow cache entries:
ip flow-export destination 10.42.42.1 9991 ip flow-export destination 10.0.101.254 1999

An engineer must export the contents of the devices object in JSON format. Which statement must be used?
A.

What is the result when a switch that is running PVST+ is added to this network?
A.
DSW2 operates in Rapid PVST+ and the new switch operates in PVST+
B.
Both switches operate in the PVST+ mode
C.
Spanning tree is disabled automatically on the network
D.
Both switches operate in the Rapid PVST+ mode.
DSW2 operates in Rapid PVST+ and the new switch operates in PVST+
Explanation: From the output we see DSW2 is running in RSTP mode (in fact Rapid PVST+ mode as Cisco does not support RSTP alone). When a new switch running PVST+ mode is added to the topology, they keep running the old STP instances as RSTP (in fact Rapid PVST+) is compatible with PVST+.
What does the Cisco DNA Center use to enable the delivery of applications through a network and to yield analytics for innovation?
A.
process adapters
B.
Command Runner
C.
intent-based APIs
D.
domain adapters
intent-based APIs
The Cisco DNA Center open platform for intent-based networking provides 360-degree extensibility across multiple components, including:
+ Intent-based APIs leverage the controller to enable business and IT applications to deliver intent to the network and to reap network analytics and insights for IT and business innovation. These enable APIs that allow Cisco DNA Center to receive input from a variety of sources, both internal to IT and from line-of-business applications, related to application policy, provisioning, software image management, and assurance.

Refer to the exhibit.
An engineer is installing a new pair of routers in a redundant configuration. Which protocol ensures that traffic is not disrupted in the event of a hardware failure?
A.
HSRPv1
B.
GLBP
C.
VRRP
D.
HSRPv2
HSRPv1
Explanation: The virtual MAC address is 0000.0c07.acXX (XX is the hexadecimal group number) so it is using HSRPv1.
Note: HSRP Version 2 uses a new MAC address which ranges from 0000.0C9F.F000 to 0000.0C9F.FFFF.
