4. Question 24 · 382 in bank

   

   Refer to the exhibit. Which command allows traffic through the IPsec tunnel configured in VPN 0?

   • Aservice netsvc1 vpn1
   • Bservice netsvc1 address 1.1.1.1
   • Cservice FW address 1.1.1.1
   • Dservice local

   Show answer

   Answer: B

   Explanation

   Half the battle is understanding the layout of this question. The question they are asking is "what is the next line in the config after the VPN1 configuration command at the bottom of the snippet" "From-vSmart" means configure this on vSmart. Service insertion requires configs on several devices. A service config needs to go on the edge router to advertise the service. The second config is done on the vSmart controller. Baio's doc is a good reference to learn the order of operation.
