A network operator is troubleshooting an IP-IP tunnel that is operationally down. The 'show interfaces terse' command shows the tunnel interface as 'down'. Which command should be used to determine if the tunnel destination is reachable?

show configuration interfaces ip-0/0/0

show interfaces ip-0/0/0 extensive

What is the purpose of configuring keepalives on an IP-IP tunnel interface?

To compress the tunneled packets.

To detect whether the remote tunnel endpoint is reachable.

To increase the MTU of the tunnel.

A network administrator is monitoring an IP-IP tunnel and notices that the input packet count is increasing but the output packet count is not. What does this indicate?

The tunnel is sending traffic but not receiving it.

The tunnel is receiving traffic but not sending it, possibly due to a routing issue.

The tunnel is operating normally.

What is the primary purpose of an IP-IP tunnel?

To encapsulate an IP packet inside another IP packet, allowing the original packet to traverse a network that would otherwise not forward it.

To compress IP headers to reduce bandwidth usage over low-speed links.

To translate between IPv4 and IPv6 addresses at the tunnel endpoints.

To provide encryption and authentication for IP packets traversing an untrusted network.
