You are working as a network technician， study the exhibit carefully. Your boss has informed youthat there have been problems with the WAN that is using EIGRP routing protocol. You arerequired to troubleshoot these problems.
Before going to the questions of this sim， we should have a quick review about GRE tunneling：GRE Quick Summary The picture below shows how to configure a GRE Tunnel between tworouters， notice that the "tunnel destination" must be the IP address of the interface， not of theopposite tunnel.

Notice： The tunnel source on one router must be specified as the tunnel destination on the otherrouter.
Below are the questions of this lab-sim. 
What is preventing the 192.168.1.150 network from appearing in the HQ router’s routing table？（）

A . The default route is missing from the Branch4 router
B . The IP address on the E0/0 interface for the Branch4 router has the wrong IP mask. It shouldbe 255.255.255.252
C . The network statement under router EIGRP on the Branch4 router is incorrect. It should benetwork 192.168.1.0 0.0.0.255.
D . When running EIGRP over GRE tunnels， you must manually configure the neighbor addressusing the eigrp neighbor ipaddress command.
E . The IP address on the tunnel interface on P4S-Branch4 is incorrect. It should be 192.168.1.12255.255.255.252
