NEW QUESTION 13

Refer to the exhibit.

The network shown in diagram is experiencing connectivity problems. Which two configuration changes will correct the problems? (Choose two.)

• 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.

Answer: BD

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
