Q1. 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.

Q2. 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.

Q3. Refer to the exhibit. A customer is running IS-IS within a network and is using BGP as a CE-PE routing protocol. Which action allows CE1 to get the subnet 10.10.2.0/24 over the CE1-PE1 link, regardless of whether there is a flap in the MPLS link or backdoor link? 

A. Configure the neighbor <PE1-IP>weight 33768 command on CE1 under the BGP process. 

B. Configure the distance bgp 115 200 200 command on CE1 under the BGP process. 

C. Configure the distance 30 ip command on CE1 under the IS-IS process. 

D. Configure the distance bgp 115 200 200 command on CE2 under the BGP process. 

E. Configure the neighbor <PE1-IP>weight 33768 command on CE2 under the BGP process.

Q4. What is NETCONF? 

A. It is a standard for installing, manipulating and deleting configuration of network devices. 

B. it is a Cisco proprietary solution to help remove the time, cost and manual steps involved in network element configuration. 

C. It is data modeling language, to help remove the time, cost and manual steps involved in network element configuration. 

D. It is a new recommendation which writes device specific CLI scripts while keeping flexibility in a vendor dependence environment.

Q5. 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.

B. It will be tail dropped. 

C. It will be dropped with a rate of 1 packet out of 30. 

D. It will be dropped with a rate of 1 packet out of 20.

C. Permanently through PE1 -> P1 -> PE4 due to lowest path metric. 

D. Initially through PE1 -> P2 -> PE4, then a few seconds later, it will be over PE1 -> P1 -> PE4
