SRWE - Module 7 - DHCPv4

Which destination IPv4 address does a DHCPv4 client use to send the initial DHCP Discover packet when the client is looking for a DHCP server?

• IP of the Default Gateway
• FF:FF:FF:FF:FF:FF

• 240.0.0.1
• 255.255.255.255
• 224.0.0.1

What is the reason why the DHCPREQUEST message is sent as a broadcast during the DHCPv4 process?

• To notify other DHCP servers on the subnet that the IP address was leased
• For routers to fill their routing tables with this new information
• To notify other hosts not to request the same IP address
• For hosts on other subnets to receive the information
• Due to the helper address being used

If more than one DHCP server is available on the local network, in which order will DHCP messages be sent between a host and a DHCP server?

• Offer, Request, Acknowledgment, Discover
• Discover, Offer, Request, Acknowledgment
• Discover, Request, Offer, Acknowledment
• Request, Offer, Discover, Acknowledment
• Discover, Offer, Reply, Acknowledment

Refer to the exhibit. What can be concluded about the configuration shown on R1?

• R1 will send a message to a local DHCPv4 client to contact a DHCPv4 server at 10.10.10.8
• R1 is operating as a DHCPv4 server
• 172.16.10.10 is the ip address of the DHCPv4 server
• R1 will broadcast DHCPv4 requests on behalf of local DHCPv4 clients
• R1 is configured as a DHCPv4 relay agent

What action does a DHCPv4 client take if it receives more than one DHCPOFFER from multiple DHCP servers?

• It sends a DHCPRequest that identifies which lease offer the client is accepting

• It discards both offers and sends a new DHCPDiscover
• It accepts both DHCPOffer messages and sends a DHCPAck
• It sends a DHCPNak and gegins the DHCP process over again

What command displays a list of all IPv4 addresses to MAC addresses

• Router# show run
• Router# show ip dhcp binding
• Router# show ip dhcp statistics
• Router# show binding table
• Router# show dhcp

Refer to the exhibit. If the IP addresses of the default gateway router and the DNS server are correct, what is the configuration problem?

• The DNS server and the default gateway router should be in the same subnet
• The default-router and dns-server commands need to be configured with subnet masks
• The IP address of the default gateway router is not contained in the excluded address list
• The IP address of the DNS server is not contained in the excluded address list
• IP address 192.168.10.254 needs to be in the main excluded address range

Refer to the exhibit. Which DHCP IPv4 message contains the following information?

• DHCPRequest
• DHCPAck
• DHCPOffer
• DHCPDiscover
• DHCPNak

What mode of operation does DHCPv4 work?

• client/server
• server/client
• server/server
• client/client

Clearing the DHCP bindings or stopping and restarting the DHCP service may result in duplicate IP addresses being temporarily assigned on the network. To remove and replace IP addresses do the following: (Choose three)

• Reboot
• ip config /release
• ip config /change
• ip config /restart
• ip config /renew
