Match the xDSL type on the above to the most appropriate implementation on the below.

Drag the IOS commands from the left that would be used to implement a GRE tunnel using the10.1.1.0.30 network on interface serial 0/0 to the correct target area on the right.

You need to configure a GRE tunnel on a IPSec router. When you are using the SDM to configurea GRE tunnel over IPsec， which two parameters are required when defining the tunnel interfaceinformation？（）

A new router was configured with the following commands：The configuration above was found on an Internet Service Provider’s （ISP） Multiprotocol LabelSwitching （MPLS） network. What is its purpose？（）

Which statement correctly describes IPsec VPN backup technology？（）

As a network engineer， do you know for what purpose SDM uses Security Device Event Exchange（SDEE）？（）
