QuestionQ1
Layer 3 VPNs
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?
- A The CE1 and CE2 VRFs can exchange routes only between their respective VRFs on PE1 and PE2.
- B All three routers must be running a distance-vector routing protocol.
- C All three routers must be running MP-BGP.
- D The CE1 and CE2 VRFs can access the default route provided by the Internet VRF.
- E Only the CE2 VRF can access the default route provided by the Internet VRF.
QuestionQ2
Layer 3 VPNs
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?
- A Configure static routing on the CE router.
- B Configure the address-family ipv4 labeled-unicast command under the neighbor configuration of the CE router for the PE.
- C Change the rd value to 65001:65001 under the VRF section of the PE router.
- D Configure OSPF on the PE router.

QuestionQ3
Layer 2 VPNsWhat is common to EVPN single-active and all-active modes?
- A They are default gateway redundancy options.
- B They are multihoming mechanisms used for CE devices.
- C They are used to provide single connection from a CE device to a service provider.
- D They are both roles that a designated router can take when MPLS is used with EVPN.
