Refer to the exhibit. Which of the following statements is true, if the command Branch1(config)#ip route 0.0.0.0 0.0.0.0 10.10.3.2 is issued on router Branch_1? (Choose two.)

The CLI would return an error, because the exit interface must be issued instead of the next hop address.

Destination IP and subnet mask is optional as long as long as the next hop is indicated

A default route will be configured on routerBranch_1.

It will forward all traffic with unknown destination network to HQ_1.

The same IP route must be configured on HQ_1router, so that the network 10.10.20.0/23 can reach 10.10.10.0/23.

Explanation

The command IP route "ip route [Destinationnetwork] [Mask] [Nexthopaddress or Exit interface] [Administrative Distance][Permanent]"; manually add routes to the router's table. In the example, default routing has been configured in the Branch1 office, which is the best for stub networks (those with only one path out of the network). The "ip route 0.0.0.0 0.0.0.0 10.10.3.2" command means that if there is not any entry for a network in the routing table, just forward it to the next hop 10.10.3.2 or HQ1 interface. Meaning that all unknown packets for example A website on the internet, coming from the Stub Network 10.10.20.0/23, will be forwarded to interface S1/0 of router HQ1. However do not forget that the other end (Head Office) also needs to know the way back to 10.10.20.0/23, in this case with a static route (not default route). If a default route is configured on the HQ1 of the Head Office, all unknown traffic will be forwarded to Branch1 Stub Network, with no possible exit.
