Apr 16, 2018 Dynamic Host Configuration Protocol (DHCP) is a standard protocol defined by RFC 1541 (which is superseded by RFC 2131) that allows a server to dynamically distribute IP addressing and configuration information to clients. Normally the DHCP server provides the client with at least this basic information: IP Address; Subnet Mask; Default Gateway. The Set-DhcpServerv4FilterList cmdlet sets the enabled state for the allow and the deny MAC address filter lists on the Dynamic Host Configuration Protocol (DHCP) server service. Examples Example 1: Enable filter lists on the DHCP server service.

Jul 12, 2013  Microsoft clients are out-of-the-box prepared to receive Microsoft Windows specific options while Microsoft DHCP servers have the ability to send DHCP options only received by Windows clients. Some applications use the content of a DHCP option to receive configuration data, for example Microsoft Lync or RES Workspace Manager.

This section contains the solutions to the thought experiments and answers to the objective review questions in this chapter.

Objective 2.1: Thought experiment

You would likely use Hot Standby Failover deploying two servers. The server at the primary location would normally service clients at the primary location, and a secondary server at a remote location would service requests for the remote site. In a Hot Standby scenario, if one of the servers fails, the other can service requests for its failed partner.

Objective 2.1: Review

  1. Correct answer: C

    1. Incorrect: This isn’t the correct split as recommended.

    2. Incorrect: This isn’t the correct split as recommended.

    3. Correct: An 80 percent/20 percent ratio for split scopes is good practice, with the primary server receiving 80 percent of the addresses and the secondary server receiving 20 percent.

    4. Incorrect: This isn’t the correct split as recommended.

  2. Correct answers: A and B

    1. Correct: 00-11-09-*-*-* is a valid filter using wildcards to match multiple MACs.

    2. Correct: 001109001111 is a valid MAC filter.

    3. Incorrect: 00: 11: 09: 09: 11: 09 isn’t a valid MAC filter; it uses colons as a separator.

    4. Incorrect: 00-11-09-7c-ef-% isn’t a valid MAC filter; it uses a percent sign as a wildcard indicator.

  3. Correct answer: A

    1. Correct: The path C:Windowssystem32dhcp is the default location for the database. This is configured in the DHCP server’s Properties sheet.

    2. Incorrect: The path C:Program FilesMicrosoftDHCPData doesn’t exist.

    3. Incorrect: The path C:Windowssystem32DHCPData doesn’t exist.

    4. Incorrect: The registry key HKEY_LOCAL_MACHINESOFTWAREMicrosoftDHCP doesn’t house the DHCP database.

  4. Microsoft word shortcuts list. Correct answer: B

    1. Incorrect: Increasing the split ratio so that the secondary server has more IP addresses from the scope makes it only so that the secondary server can assign more addresses; it doesn’t help alleviate the issue of the secondary server assigning addresses to clients at the primary location.

    2. Correct: Introducing a delay for DHCP offers from the secondary using the DHCP management console accomplishes this task by allowing the primary server to respond first but the secondary to respond after a period of time. Because DHCP clients accept the first response, this achieves the requirements.

    3. Incorrect: Reducing the load on the primary server so that it can respond faster may help, but because the scenario doesn’t indicate that the primary server was overloaded, the secondary server may just be responding faster for other reasons.

    4. Incorrect: Placing the secondary DHCP server on a different network segment to introduce a delay in the response doesn’t meet the requirement and may introduce connectivity problems for DHCP responses.

Objective 2.2: Thought experiment

  1. On the secondary server, you should make sure that the primary server is reachable. This might be achieved with a simple ping command, assuming that ICMP echo requests and echo responses aren’t blocked by a firewall. You could also use nslookup on the secondary server and point to the primary server to query for information on the contoso.com domain.

  2. On the primary server, you should ensure network connectivity to the secondary server and—importantly—ensure that zone transfers are allowed to the secondary server. This is accomplished at the zone level within the Zone Transfers tab of the Properties sheet. Ensuring that the firewall allows both UDP and TCP ports 53 inbound is also a good idea.

Objective 2.3: Thought experiment

You first need create the GPOs by using the Invoke-IpamGpoProvisioning command. Then, you need to run gpupdate /force on the servers to be managed. Finally, you need to set the server to Managed status within IPAM.

Objective 2.3: Review

    2. Incorrect: Although gpupdate is a real command, the proposed answer shows an invalid switch for this operation.

    3. Incorrect: This is an invalid command.

    4. Correct: The gpupdate /force command retrieves the appropriate GPOs from the IPAM server.
