Turn on MAC address filtering, and turn encryption on for all connections.
And limit the address pool aswell.

What ports are used by dhcp and the DHCP client?
The port 67 and port 68 are used by DHCP and the DHCP clients.
What is the use of a DHCP relay agent?
The use of a DHCP relay agent is an agent that relays DHCP between DHCP clients and DHCP servers on different IP networks. The DHCP relay agent is compliant with RFC 1542.
Which code in a DHCP audit log indicates that a DHCP lease was denied?
15
How does DHCP allow devices to communicate?
They use DHCP to assign IP Addresses to Devices such as Windows XP, Networking flashcards, OIt DHCP and BootP services, and connecting routers. The definition for DHCP is Dynamic Host Configuration Protocol.
What is DHCP nack?
dhcpnack is message from dhcp server when dhcp server is not having any ip left in address pool or client fails to respond to offer in given time
What will happen if you install a DHCP server on a network without Active Directory?
Without Active Directory the DHCP server cannot be authorized, and could therefore be considered a "rogue". What A.D do for a DHCP Server that it authorised to DHCP server to give an Ip add. to clients and authorised for update the DNS PTR records. and when we won't authorised DHCP with Active Directory it won't be update the the PTR records and won't be update the IP add. in DNS records.
For a zone in which only secure dynamic updates are allowed you have configured your dhcp server to perform dynamic updates on behalf of windows NT 4 clients other dynamic dns settings on the dhcp s?
The DHCP server is not a member of the DnsUpdateProxy security group.
What technique is a security attack that depletes the pool of IP addresses available for legitimate hosts?
DHCP Starvation
What is the first action that must be done when configuring the DHCP services in Windows Server?
Add a new scope
Using the control panel to install dhcp configure and activate dhcp with a scope of?
DHCP has to be configured by using the DHCP snap-in MMC console. This is under the Administrative Tools once DHCP has been installed. In Windows Server 2008 you add the Role, so it isn't installed via the Control Panel at all. For configuring the scope, you need to specify the address ranges to give out, any exclusions, and scope options for default gateway, etc.
What ports are used by dhcp and the DHCP client?
The port 67 and port 68 are used by DHCP and the DHCP clients.
Does the dhcp server have to be activated to issue leases to dhcp clients?
dhcp has to be authorized
What is the use of a DHCP relay agent?
The use of a DHCP relay agent is an agent that relays DHCP between DHCP clients and DHCP servers on different IP networks. The DHCP relay agent is compliant with RFC 1542.
What command create DHCP address pool on a router?
router (config)# ip dhcp servicerouter (dhcp-config)# ip dhcp pool router (dhcp-config)# network
Describe the process of installing a DHCP server in an AD infrastructure?
Terms you'll need to understand: * DHCP * Lease duration * Scopes * Superscopes * Multicast scopes * Scope options Techniques you'll need to master: * Installing DHCP * Understanding the DHCP lease process * Creating scopes, superscopes, and multicast scopes * Configuring the lease duration * Configuring optional IP parameters that can be assigned to DHCP clients * Understanding how DHCP interacts with DNS * Configuring DHCP for DNS integration * Authorizing a DHCP server in Active Directory * Managing a DHCP server * Monitoring a DHCP server The TCP/IP protocol is an Active Directory operational requirement. This means that all computers on a Windows 2000 network require a unique IP address to communicate with the Active Directory. Static IP addresses can add a lot of administrative overhead. Not only can management of static IP addresses become time consuming, but such management also increases the chances of misconfigured parameters. Imagine having to manually type 10,000 IP addresses and not make a single error. The Dynamic Host Configuration Protocol (DHCP) can be implemented to centralize the administration of IPaddresses. Through DHCP, many of the tasks associated with IP addressing can be automated. However, implementing DHCP also introduces some security issues because anyone with physical access to the network can plug in a laptop and obtain IP information about the internal network. In this chapter, you'll learn how to implement a DHCP server, including the installation process, authorization of the server, and the configuration of DHCP scopes. The chapter ends by looking at how to manage a DHCP server and monitor its performance.
What port is DHCP used?
(DHCP) Dynamic host Configuration Protocol. The Default Port Number is: for DHCP client : 546 for DHCP server : 547
In a domain installations of DHCP require the authorization of the dhcp server before IP addresses can be allocated True or False?
yes DHCP require the authorization of the dhcp server before IP addresses can be allocated because until we authorize DHCP server the network does not know who is the dhcp server for the subnet. The DHCP server broadcasts the information to all.
