D - Transport to Transport

Zdrobici is correct. refer to Figure 7 in: https://www.networkacademy.io/ccie-enterprise/sdwan/connecting-to-the-wan-using-tloc-extension All required configuration is shown in figure 7 above. Once the config is applied, we can see that vEdge-2’s ge0/0 is NOW A TRANSPORT interface and acts as a local TLOC marked with the “biz-internet” color.

C is correct The primary function of tloc-extension is to extend the transport interface properties to a service interface. This means that after the configuration, ge0/2.101 can now use ge0/0's transport capabilities for overlay traffic. However, ge0/2.101 does not become a transport interface itself; it remains a service interface that can utilize the transport functions of ge0/0.

C is correct

D - in the device template TLOCs (extension) are configured in the transport.

I agree with the volks: D

initially port type is SERVICE, after tloc-ext config is ADDED is becoming TRANSPORT. so we can say that the bound is done between TRANSP interfaces, because bound is done after tloc-ext cfg is added, wright? take a look on the cli outputs from https://www.networkacademy.io/ccie-enterprise/sdwan/connecting-to-the-wan-using-tloc-extension

TLOC Ext interface is NOT service as it is connected to other WAN edge, no service/local network connections

D is correct. Reference: https://ccieme.wordpress.com/category/networking/sd-wan/tloc-extensions/ Go to the end of the page and see the TLOC-extension example diagram.

TLOCs are always in VPN0 which is Transport answer D

It's C.. Check the "show interface| tab " in lab if you don't belive. +https://www.cisco.com/c/en/us/td/docs/routers/sdwan/configuration/system-interface/vedge/systems-interfaces-book/configure-interfaces.html

C Is correct , they are asking about the port-type not the VPN type ! https://www.cisco.com/c/en/us/td/docs/routers/sdwan/configuration/system-interface/vedge-20-x/systems-interfaces-book/configure-interfaces.html

the "extention" command can only be made between transport interfaces

transport to transport

Correct Answer is C, I have tried it in the lab. Use show command : show interface description vpn 0 | tab

Just tried it in lab, It is C, only interfaces with 'tunnel-interface' command show up as transport.

It should be C , Before applying Tloc-extension , ge 0/2.101 is a service port , The port-type will be changing after applying the command
