Question 1

If you decide to set the port speed manually, make positively sure to set the same speed on both sides of a link. T/F p 734

Answer 1

True

Question 2

There are generally three duplex settings on each port of a network switch. p 734

Answer 2

full
half
auto

Question 3

What is Port duplex mismatch. p 734

Answer 3

In order for two devices to connect effectively, the duplex setting has to match on both sides of the connection. If one side of a connection is set to full and the other is set to half, they’re mismatched. More elusively, if both sides are set to auto, but the devices are different, you can also end up with a mismatch because the device on one side defaults to full and the other one defaults to half.

Question 4

What happens when you have an Incorrect IP address. p 735

Answer 4

An incorrect address on a client will keep that client from being able to communicate and may even cause a conflict with another client on the network; and a bad address on a server or router interface can be disastrous and affect a multitude of users.

Question 5

What does a Wrong gateway do. p 736

Answer 5

If a device compares where a packet wants to go with the network it’s currently on, and finds that the packet needs to go to another network, the router and the device will send that packet to the gateway to be forwarded to the other network.

Question 6

If you’re configuring a static IP address and default gateway, you need to verify the router’s address. T/F p736

Answer 6

True

Question 7

What happens when you have the Wrong subnet mask. p 736

Answer 7

a subnet mask that is configured wrong has the same nasty effect as a wrong IP address configuration does on communications.
