A. router ospf 1 

area0 

interface GigabitEthernet 0/1 

passive 

B. router ospf 1 

area0 

interface GigabitEthernet 0/1 

C. router ospf 1 

area 0 

interface GigabitEthernet 0/1

stub-router 

router-lsa r-bit 

D. router ospf 1 

area 0 

interface GigabitEthernet 0/1 

demand-circuit 

point-to-point 

Answer:


Q12. Refer to the exhibit. 

OSPF is already running with the default OSPF parameters. R1 has added a new subnet (loopback 11). What will occur in regards to SPT computing on R2 router? 

A. Adding ispf command on R2 router, the entire SPT will be computed on R2 router. 

B. Because 10.11.11.11/32 prefix information will be in a LSA type 3 on R2 router's OSPF database, R2 router will run partial SPF computation. 

C. Adding ispf command on R2 router, R2 router will recompute only the affected part of tree. 

D. Because 10.11.11.11/32 prefix will be a LSA type 1 on R2 router's OSPF database. R2 router will always run a full SPF computation, even though an OSPF optimization is applied on R2 router. 

Answer:

C. Owner SDR can be reloaded, without affecting all non-SDRs. 

D. The logical router has dedicated route processor. 

E. The logical router can share line cards. 

F. The fabric and system controller module are shared by all logical routers. 

Answer: A,D,F 


Q14. Which are the three header fields that affect how Equal-Cost Multipath hashes traffic flow into interface groups? (Choose three.)

Q15. Refer to the exhibit: 

A regional operations center recently set up a MPLS Inter-AS Option B solution for two service providers There is no intercommunication between CE1 and CE2 sites yet While troubleshooting this issue on the ASBR1 router, the operations engineer sees the following log: 

BGP(4): 10.24.32.253 rcvd 100:101:40.72.97.0/24, label 136 -- DENIED due to: extended community not supported; What does this log mean? 

A. The route-target value does not match the one in the local VRF 

B. The community that was applied on ASBR 10.24.32.253 does not match the local policies 

C. The bgp default route-target filter command is missing on both inter-AS ASBRs 

D. The BGP command retain route-target all is missing 

Answer:


Q16. In a virtualization concept, which is one of the characteristic of the HVR solution? A. introduces significant contention of resources 

B. implements shared control plane resources 

C. implements dedicated chassis resources 

D. implements dedicated data plane resources 

Answer:


Q17. Refer to the exhibit. 

PIM sparse mode is implemented in the network RPF succeeds under which condition? 

A. The RPF check succeeds for the next hop whose router ID is the highest. 

B. The RPF check succeeds for the highest DR priority for the PIM router. 

C. The RPF check succeeds for both PIM neighbors, and traffic load-balances across both neighbors. 

D. The RPF check succeeds for the highest interface IP address for the PIM router. 

Answer:


Q18. QoS is applied on an outgoing interface as shown below: 

What will the QoS result be for egress traffic with an average queue depth of 40 that is marked as DSCP AF32? 

A. Traffic will be dropped with a random rate less than the one defined by MPD. 

B. All traffic will be tail dropped. 

C. Traffic will be dropped with a rate of 1 packet out of 20. 

D. Traffic will be dropped with a rate of 1 packet out of 30. 

Answer:


Q19. DRAG DROP 

Drag each resiliency mechanism on the left to its corresponding technology on the right. 

Answer: 


Q20. Refer to exhibit. NAT64 stateless configuration has been applied on RT1 router. The NAT64 prefix stateless used on this scenario is 2001:DB8:2::/96. ‘Host IPv4 only’ needs to test the connectivity with ‘Host IPv6 only’ using a ping command. Which is the correct ping command ‘Host IPv4 only’ should use? 

A. ping 27.1.1.10 

B. ping 27.1.1.10 source 2001:db8:2::7001:10A 

C. ping 2001:db8:2::7001:10A
