Q1. Customers connecting to a Service Provider for Internet access are intending to implement redundant peering. The design requirements call for preferring a primary link for both ingress and egress traffic. Secondary links should be used only during primary outages. What two BGP deployment options will accomplish this design goal? (Choose two.) 

A. On the router handling the secondary link, advertise routes with a MED value of 0. 

B. On the router handling the primary link, set the weight for all incoming routes to be a value of 0. 

C. On the router handling the secondary link, advertise all routes with a longer AS-PATH value. 

D. On the router handling the primary link, advertise all routes with a longer AS-PATH value. 

E. On the router handling the secondary link, set the local preference for all incoming routes to be a value of 0.

Q3. Refer to the exhibit. A web server is connected to a switch via two Gigabit Ethernet links. These two links are bundled into a single logical link that provides the aggregate bandwidth of 2 Gbps. The support engineer notices that traffic from the Internet to the web server uses both Gigabit Ethernet links. However, traffic from the web server to the Internet uses only one link. 

Which CLI command on the exhibit causes this behavior? 

A. lacp port-priority 32768 in interface configuration mode 

B. channel-group 5 mode passive 

C. lacp port-priority 32768 in global configuration mode 

D. port-channel load-balance dst-mac

Q4. 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.

Q5. In an MPLS VPN environment, the QoS marking over the MPLS backbone must be different from the one that is received from the customer. The forwarding on the egress PE is based on the marking that is set by the ingress PE. Which null label and QoS mode can achieve this? 

A. MPLS explicit null with pipe mode 

B. MPLS implicit null with short pipe mode 

C. MPLS implicit null with uniform mode 

D. MPLS explicit null with uniform mode 

E. MPLS explicit null with short pipe mode 

F. MPLS implicit null with pipe mode

Q7. Refer to the exhibit. 

When a traceroute is performed from a PC behind R2, the next hop on R1 for IPv4 is 10.0.1.2, and for IPv6 it is 2001:DB8:2:2. What is causing thus behavior? 

A. GigabitEthernet2/1 has a Level 1-only adjacency. This causes it to be the preferred path for the IPv6 packets. 

B. When SPF ran on R2, it calculated two equal paths to R1. It was a coincidence that than the packets choose different paths. 

C. Multitopology is enabled on R2, which causes the IPv6 packets to use a different path than the IPv4 packets. 

D. 2001:DB8:2::2 is on a Gigabit Ethernet interface. Because its speed is higher than Fast Ethernet, the IS-IS metric is preferred.

Q8. Which Cisco IOS XR Virtualization technology provides full isolation between virtualized routing instances for extra control plane resources?

Q9. 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.
