The network shown in the diagram is experiencing connectivity problems. Which of the following will correct the problems? (Choose two.)
A. Configure the gateway on Host A as 10.1.1.1. B. Configure the gateway on Host B as 10.1.2.254. C. Configure the IP address of Host A as 10.1.2.2. D. Configure the IP address of Host B as 10.1.2.2. E. Configure the masks on both hosts to be 255.255.255.224. F. Configure the masks on both hosts to be 255.255.255.240.
Correct Answers: B, D
Explanation:
The switch 1 is configured with two VLANs: VLAN1 and VLAN2.
The IP information of member Host A in VLAN1 is as follows:
Address : 10.1.1.126
Mask : 255.255.255.0
Gateway : 10.1.1.254
The IP information of member Host B in VLAN2 is as follows:
Address : 10.1.1.12
Mask : 255.255.255.0
Gateway : 10.1.1.254
The configuration of sub-interface on router 2 is as follows:
Fa0/0.1 — 10.1.1.254/24 VLAN1
Fa0/0.2 — 10.1.2.254/24 VLAN2
It is obvious that the configurations of the gateways of members in VLAN2 and the associated network segments are wrong. The layer3 addressing information of Host B should
be modified as follows:
Address : 10.1.2.X
Mask : 255.255.255.0
