QUESTION 22 Exhibit:

You work as a network administrator at Contoso Inc Hosts in the Contoso sales

department are unable to access a new server at the Branch Office Consider the IP

addressi ng scheme in the accompanying graphic to determine the problem

A The default gateway of the workstations in the sales department is incorrect

B The subnet mask of the workstations in the sales department is incorrect

C The default gateway of the server at the Branch Office is incorrect

D The host address of the server at the Branch Office is invalid

E The serial 0 interface on the Main Office router and the serial 1 interface on the Branch Office router are not on the same sub network

Answer: D

Explanation: When you convert the IP address (205.113.20.96) of the server and the subnet mask (255.255.255.240) to binary you will get the following results: (IP address first and then the subnet mask.) 11001101 01110001 00010100 01100000 11111111 11111111 11111111

11100000 Thus it is determined that the IP address on the host is in fact the subnet address This

is what would be causing the network problems

Incorrect Answers:

A The default gateway in the sales department is correct

B The subnet mask is correct

C The default gateway in the branch office is correct

E This is no problem here Steve McQuerry Interconnecting Cisco Network Devices (Cisco Press: 2000) pages 233 - 234
