Question 1 · Layer 3 VPNs Open

Refer to the exhibit. PE1 and PE2 exchange VPNv4 routes for CE1 and CE2, and PE3 holds the default route to the internet. If all three devices operate normally, which two conclusions describe this configuration? (Choose two.)

Answer: C, E A VRF imports an exported VPN route only when the route’s route target matches one of its import route targets. The Internet VRF exports the default route with route target 300:3, which CE2 imports but CE1 does not; therefore, only CE2 can use that default route. VPNv4 reachability is exchanged between PE routers through MP-BGP. **Learn more:** [Cisco IOS XE: Multiprotocol BGP MPLS VPN](https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/mp_l3_vpns/configuration/xe-17/mp-l3-vpns-xe-17-book/multiprotocol-bgp-mpls-vpn.html) · [Cisco IOS XR: Implementing MPLS Layer 3 VPNs](https://www.cisco.com/c/en/us/td/docs/iosxr/ncs5500/vpn/26xx/configuration/guide/b-l3vpn-cg-ncs5500-26xx/implementing-mpls-layer-3-VPNs.html)

Question 2 · Layer 3 VPNs Open

Refer to the exhibit. The CE router has formed a BGP peering with the PE router, and the CE will use the PE core infrastructure as a backbone carrier to support CSC. What additional task can you perform to complete the configuration?

Answer: B Carrier Supporting Carrier requires the CSC-CE and CSC-PE to exchange IPv4 routes together with MPLS labels through BGP. The PE neighbor already uses the IPv4 labeled-unicast address family, so the CE neighbor must also be configured for `address-family ipv4 labeled-unicast` to enable labeled route exchange. **Learn more:** [Cisco: Configure Carrier Supporting Carrier for L3VPN on CSC-PE](https://www.cisco.com/c/en/us/td/docs/iosxr/cisco8000/l3vpn/l3vpn-config-cisco8000/carrier-supporting-carrier-for-l3vpn-w/configure-carrier-supporting-carrier-for-l3vpn.html)

Question 3 · Layer 2 VPNs Open

What is common to EVPN single-active and all-active modes?

Answer: B EVPN single-active and all-active are multihoming mechanisms for CE devices. Single-active forwards through one active provider-edge attachment for an Ethernet segment, whereas all-active can forward through multiple attached provider-edge devices.
