Demo Questions
Question 1
Your server administrator asks you to preserve the inner VLAN tags of the frames coming from a Layer 2 VXLAN Gateway of the EVPN-enabled segment.
Which two parameters must you add to the configuration to allow the VLAN tag to be passed? (Choose two.)
- layer2-protocol-tunneling
- decapsulate-accept-inner-vlan
- dotlq-tunneling
- encapsulate-inner-vlan
Correct answer: BD

Question 2
Which two statements are correct when performing a unified ISSU? (Choose two.)
- The master Routing Engine and backup Routing Engine must be running the same software version before you can perform a unified ISSU.
- Unicast RPF-related statistics are not saved across a unified ISSU, and the unicast RPF counters are reset to zero during a unified ISSU.
- Unicast RPF-related statistics are saved across a unified ISSU, and the unicast RPF counters are not reset to zero during a unified ISSU.
- The backup Routing Engine must be running the most recent software version before you can perform a unified ISSU.

Question 3
Referring to the exhibit, PE1 and PE2 are acting as MPLS Layer 3 VPN PEs to provide the DCI between DC1 and DC2, which are IP Fabrics. Leaf 1 and Leaf 2 are QFX5100 Series devices acting as VXLAN Layer 2 Gateways using EVPN signaling for the same VXLAN segment.
Which statement is correct about the Edge1 device in this scenario?
- Edge1 must be configured for MP-BGP using EVPN signaling.
- Edge1 must be configured for MP-BGP using L3VPN signaling.
- Edge1 must be configured for BGP labeled unicast on its PE1-facing interface.
- Edge1’s routing table must contain an IP route to both Leaf1 and Leaf2.
Correct answer: A
Explanation:
Assumption here that the MPLS backbone network offers EVPN; this is the most fully-featured solution. This could also be achieved via C; BGP-LU shared with the provider, basically extending MPLS down to the Edge1+2 routers; this is less ‘risky’ for the MPLS backbone operator. B and D are ignoring EVPN/VXLAN components and refer to traditional Layer 3 IP routing.
