Q1. 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 

D. ping 2001:db8:2::112.1.1.10 

E. ping 2001:db8:2::27.1.1.10

Q2. Refer to the exhibit. Router RT1 has three equal-cost paths back to the source. Which configuration should be applied in order to load-balance the multicast traffic across all three links. 

A. Create three static multicast routes where each pointing out to one or three interfaces. 

B. Enable PIM multipath. 

C. Create a tunnel interface between RT1 and RT2. Enable PIM on the interface tunnel and disable PIM on the three interfaces part of equal-cost path between RT1 and RT2. 

D. PIM load balance is not possible. PIM only chooses one interface for RFC check and prunes the other interfaces.

Q4. Refer to the exhibit. Both MPLS TE tunnel 14 and MPLS TE tunnel 124 pass over the same physical links. Which configuration on R1 enables TE 14 to be the primary tunnel and TE 124 to become active when TE 14 is admin disabled?

! 

Interface Tunnel124 

tunnel mpls traffic-eng priority 5 4

Q5. Refer to the exhibit. 

An engineer observes that the MC-LAG bundle is down on the active aggregation device. Which is the reason for this issue? 

A. The number of configured minimum links is the same of the maximum links available in the bundle. 

B. The ICCP redundancy group is configured with the same system MAC address 

C. The ICCP redundancy group is configured with the system priority. 

D. The number of minimum configured links is greater than the number of links operational in the bundle

Q6. 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.

.Router_2 requires the least configuration 

In order to achieve the OSPF LSDB optimization on Router_3. which Cisco IOS command should the engineer use on Router_2? 

A. area 1 nssa default-information-originate 

B. area n nssa no-summary 

area 1 nssa no-redistribution 

C. area 1 nssa no-redistribution 

area 1 nssa default-information-originate 

D. area 1 nssa no-summary 

E. area 1 nssa no-redistribution 

F. area 1 nssa no-summary
