DHCP

What was a limitation of the Bootstrap Protocol (BOOTP)?

• It could not assign IP addresses.

• It required manual configuration for some settings.

• It was only compatible with IPv6.

• It was too complex for small networks.

What does the acronym DORA represent in the context of the DHCP process?

• Discover, Offer, Route, Acknowledge

• Detect, Obtain, Release, Assign

• Discover, Offer, Request, Acknowledge

• Define, Organize, Resolve, Allocate

What are the source and destination IP addresses for a DHCP Discover packet sent by a client without an IP address?

• Source: 127.0.0.1, Destination: 255.255.255.255

• Source: 0.0.0.0, Destination: 255.255.255.255

• Source: Client's MAC address, Destination: DHCP server's IP

• Source: DHCP server's IP, Destination: Client's MAC address

When a DHCP server sends an Offer packet to a client that has not yet received an IP address, what is the destination IP address?

• The client's proposed IP address.

• The DHCP server's IP address.

• A broadcast address (255.255.255.255).

• The default gateway's IP address.

What are the source and destination IP addresses and UDP ports for a DHCP Request sent by a client that has not yet received an IP address?

• Source: 0.0.0.0:udp/68, Destination: 255.255.255.255:udp/67

• Source: 0.0.0.0:udp/67, Destination: 255.255.255.255:udp/68

• Source: Client's assigned IP:udp/68, Destination: DHCP Server IP:udp/67

• Source: Client's assigned IP:udp/67, Destination: DHCP Server IP:udp/68

What are the source and destination IP addresses and UDP ports for a DHCP Acknowledgment sent by the DHCP server?

• Source: DHCP Server IP:udp/68, Destination: 255.255.255.255:udp/67

• Source: DHCP Server IP:udp/67, Destination: 255.255.255.255:udp/68

• Source: 0.0.0.0:udp/68, Destination: 255.255.255.255:udp/67

• Source: 0.0.0.0:udp/67, Destination: 255.255.255.255:udp/68

What is a significant limitation of the DHCP process in an enterprise network?

• It only supports IPv6 addresses.

• It requires manual configuration of each client.

• Broadcasts are limited to the local subnet and do not traverse routers.

• It cannot provide DNS server information.

How does a DHCP relay (IP helper) on a router facilitate DHCP communication across different subnets?

• It converts unicast DHCP messages into broadcast messages.

• It assigns static IP addresses to clients on remote subnets.

• It changes broadcast DHCP Discover messages into unicast messages directed to the DHCP server.

• It acts as a secondary DHCP server for redundancy.
