Lesson 19: Understanding DHCP

Question 1

If a host computer or device is on an active network with other clients receiving DHCP addresses, why might this specific computer or device not get an IPv4 address?

Answer 1

If other computers and devices on a given network are able to secure DHCP addresses, it is likely that the server has run out of DHCP leases.

Question 2

How can you determine whether a host has a routable IPv4 address or a link-local address?

Answer 2

Because a link-local address must fall in the 169.254.x.x range, checking the current IPv4 address of the client will provide the answer.

Question 3

Before you can statically map an IPv4 address to a specific client, what must you know about that client before you can create a static address for that client?

Answer 3

You must know the MAC address of the client; if the client already has a DHCP lease, simply create a static address from that client’s entry in the Clients pane.

Question 4

Where would you find log entries related only to the DHCP service?

Answer 4

You would find log entries only related to the DHCP service in the Server app’s Logs pane, in the Service Log under the DHCP section.
