300-415 Question #431: Real Exam Question with Answer & Explanation
The correct answer is A: vpn 0 interface ge0/0 ip address 99.0.0.1/30 tunnel-interface encapsulation ipsec group 101 color silver interface ge0/1 ip address 192.0.0.1/30 tunnel-interface encapsulation ipsec group 102 color gold. On a Cisco SD-WAN vEdge, TLOC colors must be chosen from the predefined set; 'silver' and 'gold' are valid colors that match the exhibit's interface assignments.
WAN Edge Router Deployment
Question
Refer to the exhibit. An engineer is performing a proof of concept before migrating to the Cisco Catalyst SD-WAN solution in the data center by configuring the WAN vEdge101 device. Which configuration accomplishes the task?
Options
- Avpn 0 interface ge0/0 ip address 99.0.0.1/30 tunnel-interface encapsulation ipsec group 101 color silver interface ge0/1 ip address 192.0.0.1/30 tunnel-interface encapsulation ipsec group 102 color gold
- Bvpn 0 interface ge0/0 ip address 99.0.0.1/30 tunnel-interface encapsulation ipsec group 101 color public-internet interface ge0/1 ip address 192.0.0.1/30 tunnel-interface encapsulation ipsec group 102 color custom1
- Cvpn 0 interface ge0/0 ip address 99.0.0.1/30 tunnel-interface encapsulation ipsec group 101 color mpls interface ge0/1 ip address 192.0.0.1/30 tunnel-interface encapsulation ipsec group 102 color metro-ethernet
- Dvpn 0 interface ge0/0 ip address 99.0.0.1/30 tunnel-interface encapsulation ipsec group 101 color mpls interface ge0/1 ip address 192.0.0.1/30 tunnel-interface encapsulation ipsec group 102 color green
Explanation
On a Cisco SD-WAN vEdge, TLOC colors must be chosen from the predefined set; 'silver' and 'gold' are valid colors that match the exhibit's interface assignments.
Common mistakes.
- B. 'public-internet' is a valid color but 'custom1' and 'public-internet' do not match the color labels required by the exhibit for the two interfaces shown.
- C. 'mpls' and 'metro-ethernet' are valid colors but do not correspond to the transport types depicted in the exhibit, making this configuration incorrect for the proof-of-concept scenario.
- D. 'green' is not a valid predefined TLOC color on Cisco SD-WAN vEdge devices, so this configuration would be rejected or produce an unexpected transport identity.
