Question No. 1

A Cisco IOS XR router is acting as a PE and is running EIGRP as the CE-PE routing protocol. SOOmust be configured. Under which subconfiguration mode should SOO be configured?

• A. RP/0/0/CPU0:XR1(config-eigrp)
• B. RP/0/0/CPU0:XR1(config-eigrp-vrf-af-if)
• C. RP/0/0/CPU0:XR1(config-eigrp-vrf)
• D. RP/0/0/CPU0:XR1(config-eigrp-vrf-af)

Question No. 2

A financial institution is experiencing rapid growth in VPWS branch connections and expects to have

approximately 110 sites. If all the branch uplinks implement Ethernet technology, which architectural changes can you propose?

• A. a point-to-multipoint or multipoint-to-multipoint technology such as VPLS. to provide more scalability while reducing the administrative required overhead
• B. an L2TPv3 implementation. to provide greater flexibility with no topology change
• C. a full-mesh BGP network. to better implement a loop-free topology
• D. a traditional MPLS L3VPN solution

Question No. 3

When implementing MPLS Layer 3 VPNs with customers running OSPF as the CE-PE routing protocol, the service provider MPLS backbone looks like what to the CE routers?

• A. the backbone (Area 0)
• B. an external routing domain
• C. a superbackbone that is transparent to the CE OSPF routers
• D. a transit area (similar to a transit area for supporting virtual links)

Question No. 4

With Layer 3 MPLS VPN implementations on Cisco IOS XR PE routers, an interface is assigned to a VRF using the vrf command in which configuration mode?

• A. RP/0/RP0/CPU0:PE(config-vrf)#
• B. RP/0/RP0/CPU0:PE(config-if)#
• C. RP/0/RP0/CPU0:PE(config-bgp)#
• D. RP/0/RP0/CPU0:PE(config-bgp-af)#

Question No. 5

Which option is the primary purpose of central service MPLS VPNs?

• A. provide customer access to provider resources while ensuring customers cannot communicate directly
• B. provide the provider access to customer resources while ensuring customers cannot communicate directly
• C. provide other service providers access to provider resources
• D. provide other service providers access to customer resources

Question No. 6

Which two configuration techniques are used when building MPLS L2VPNs? (Choose two.)

• A. Configure a pseudowire xconnect command to extend CE interfaces across the service provider backbone.
• B. Configure all VRFs with standard route import and export tags, to ensure proper routing across the service provider backbone.
• C. On all PE routers that connect to CE routers, implement a VRF that will be used for client routing.
• D. Implement a full mesh between PE routers to support VPLS handoffs with CE routers.
• E. Use RSVP-TE to configure the autoroute announce command to ensure that traffic is routed onto a TE tunnel that is dedicated for client traffic.
