Q71. Refer to the exhibit. 

A network engineer is troubleshooting PTP on Cisco ASR 9000 router. What can be concluded about the interface based on output provided? 

A. The interface receives timestamps from a master clock, but the router's clock is not yet synchronized to the master. 

B. The interface is aware of a better clock than the one it would advertise if it was in Master state. 

C. The interface is not yet ready to participate on PTP. 

D. The interface is about to go into Master state. 

Answer:


Q72. DRAG DROP 

Refer to the exhibit. 

PE1 and PE2 has a Layer 2 VPN over a GRE tunnel. This GRE tunnel built between P1 and P2 has LDP enabled. Consider a packet capture of the packets from CE1 and CE2 at P1 and R1 link. Drag the headers on the left and drop them on the right in the order of the encapsulation, starting from the inner header (at the top) to the outer header (at the bottom). 

Answer: 


Q73. Which two statements about forwarding equivalence class (FEC) are true? (Choose two) 

A. FEC might correspond to a destination IP subnet, but it might also correspond to any traffic class that the edge LSR considers significant. 

B. FEC is a group of IP packets that is forwarded over a different path, but with the same forwarding treatment. 

C. FEC is a group of IP packets that is forwarded over the same path, and with the same forwarding treatment. 

D. FEC is a group of IP packets that is forwarded over a different path, but with the different forwarding treatment. 

E. FEC is a group of IP packets that is forwarded over the same path, but with a different forwarding treatment. 

Answer: A,C 


Q74. Refer to the exhibit.

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.

Q75. Which information is carried in the OSPFv3 intra-area Prefix LSA? 

A. All link-local addresses 

B. All IPv6 prefix and topology information that OSPFv2 included in Router LSA and Network LSA 

C. List of options associated with the link to all other routers attached to the link 

D. All prefix-specific information that OSPFv2 included in Router LSA and Network LSA 

Answer:

Explanation: 

OSPFv3's new LSA, the Intra-area Prefix LSA (type 9), handles intra-area network information that was previously included in OSPFv2 type 2 LSAs. It is used in order to advertise one or more IPv6 prefixes. The prefixes are associated with router segment, stub network segment or transit network segment. Intra-area prefix LSAs (type 9) & Inter-Area-Prefix-LSA (type 3) carry all IPv6 prefix information, which, in IPv4, is included in router LSAs and network LSAs.

Q76. In which way does the DS-Lite IPv6 transitioning mechanism differ from IPv6 Dual-Stack? 

A. DS-Lite is a combination of tunnel and translation technologies. 

B. DS-Lite is a transition technology that gives full IPv6 connectivity for IPv6 capable hosts that are on the IPv4 Internet but have no native connection to an IPv6 network. 

C. DS-Lite is an automatic tunnel where the tunnel destination is determined by the IPv4 address extracted from the IPv6 address that starts with the prefix 2002::/16. 

D. DS-Lite is a stateless tunneling mechanism with a lightweight and secure manner without requiring upgrades to existing IPv4 access network infrastructure.

D. only for unicast over MPLS VPN 

E. for all the default MDT and mVPN models
