Your task is the fix a router that a non-Cisco certified employee has been working on

A router interface has been incorrectly configured with a subnet broadcast address

Which set of commands will remove the incorrect IP address from the interface and replace it with the first usable IP address for the same subnet?

A router(config-if)# clear ip address 195.168.45.21 255.255.255.248

connectivity The routers have been configured with the following specifications:

ƒ The routers are named TestKing1, TestKing2, and TestKing3

ƒ RIP is the routing protocol

ƒ Clocking signal is provided on the serial 0 interfaces

ƒ The password on each router is "testking"

ƒ The subnet mask on all interfaces is the default mask

ƒ The IP addresses are listed in the chart below

Looking at the diagram above ports 1 through 4 are assigned to VLAN1 and ports 5 through 8 are

assigned to VLAN3 on each switch The switches are interconnected over an ISL trunk link

Which of the following actions would test proper VLAN and trunk operation? (Choose three.)

A Host 2-1 can ping Host 2-2

B Host 2-1 can ping Host 7-2

C Host 2-1 can not ping Host 2-2

D Host 7-1 can not ping Host 2-2

E Host 7-1 can ping Host 7-2

Answer: A, D, E

Explanation:

A: Host 2-1 and Host 2-2 are both in VLAN1 and a ping should be successful

D: Host 7-1 is in VLAN3 while Host 2-2 is in VLAN1 A ping between those hosts should fail

E: Host 7-1 and Host 7-2 are both in VLAN1 and a ping should be successful

Incorrect Answers

B: Host 2-1 and Host 7-2 are in different VLANs and a ping should fail

C: Host 2-1 and Host 2-2 are both in VLAN1 and a ping should be successful

You work as a network administrator at TestKing Inc Hosts in the TestKing sales department are

unable to access a new server at the Branch Office Consider the IP addressing 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 subnetwork

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
