Which two interface types are used as tunnel endpoints? (Choose two.)
Tunnel endpoints are specific types of network interfaces that are used for establishing tunnels, which encapsulate packets for transmission over a network. In this context, 'gr' stands for GRE (Generic Routing Encapsulation) tunnels and 'ip' refers to IP-in-IP tunnels. These interface types are specifically designed to handle tunnel protocols, making them the correct choices.
"endpoint", IMHO, means an interface that can be the source and/or the destination of a tunnel interface. I would have chosen A and B
tunnel-end-point name { ipv4 { source-address 10.255.1.1; destination-address 10.255.2.0/25; } gre { key 9; } } https://www.juniper.net/documentation/us/en/software/junos/routing-policy/topics/ref/statement/tunnel-end-point-edit-firewall.html
