Topic 1, Exam Pool A
An engineer configured a leak-map command to summarize EIGRP routes and advertise specifically loopback 0 with an IP of 10.1.1.1.255.255.255.252 along with the summary route. After finishing configuration, the customer complained not receiving summary route with specific loopback address. Which two configurations will fix it? (Choose two.)
A.
Configure access-list 1 permit 10.1.1.0.0.0.0.3.
B.
Configure access-list 1 permit 10.1.1.1.0.0.0.252.
C.
Configure access-list 1 and match under route-map Leak-Route.
D.
Configure route-map Leak-Route permit 10 and match access-list 1.
E.
Configure route-map Leak-Route permit 20.
Configure access-list 1 permit 10.1.1.0.0.0.0.3.
Configure route-map Leak-Route permit 10 and match access-list 1.
Explanation: When you configure an EIGRP summary route, all networks that fall within the range of your summary are suppressed and no longer advertised on the interface. Only the summary route is advertised. But if we want to advertise a network that has been suppressed along with the summary route then we can use leak-map feature. The below commands will fix the configuration in this question:
R1(config)#access-list 1 permit 10.1.1.0 0.0.0.3
R1(config)#route-map Leak-Route permit 10 // this command will also remove the
“route_map
Leak-Route deny 10” command.
R1(config-route-map)#match ip address 1
What is the role of a route distinguisher via a VRF-Lite setup implementation?
A.
It extends the IP address to identify which VFP instance it belongs to.
B.
It manages the import and export of routes between two or more VRF instances
C.
It enables multicast distribution for VRF-Lite setups to enhance EGP routing protocol capabilities
D.
It enables multicast distribution for VRF-Lite setups to enhance IGP routing protocol capabilities
It extends the IP address to identify which VFP instance it belongs to.
Which statement about IPv6 ND inspection is true?
A.

B.
It learns and secures bindings for stateless autoconfiguration addresses in Layer 2 neighbor tables
C.
It learns and secures bindings for stateful autoconfiguration addresses in Layer 3 neighbor tables.
D.
It learns and secures bindings for stateful autoconfiguration addresses in Layer 2 neighbor tables.
It learns and secures bindings for stateless autoconfiguration addresses in Layer 2 neighbor tables
Refer to the exhibit.
Network operations cannot read or write any configuration on the device with this configuration from the operations subnet. Which two configurations fix the issue? (Choose two.)
A.
Configure SNMP rw permission in addition to community ciscotest.
B.
Modify access list 1 and allow operations subnet in the access list.
C.
Modify access list 1 and allow SNMP in the access list.
D.
Configure SNMP rw permission in addition to version 1.
E.
Configure SNMP rw permission in addition to community ciscotest 1.
Modify access list 1 and allow operations subnet in the access list.
Configure SNMP rw permission in addition to community ciscotest 1.
Which transport layer protocol is used to form LDP sessions?
A.
UDP
B.
SCTP
C.
TCP
D.
RDP
TCP
Explanation: LDP multicasts hello messages to a well-known UDP port (646) in order to discover neighbors. Once the discovery is accomplished, a TCP connection (port 646) is established and the LDP session begins. LDP keepalives ensure the health of the session.
Thanks to the LDP session, LDP messages create the label mappings required for a FEC. Withdraw messages are used when FECs need to be torn down.
