Quiz 8 CCNA

What is the destination IP address when an IPv4 host sends a DHCPDISCOVER message?

255.255.255.255

When a client is requesting an initial address lease from a DHCP server, why is the DHCPREQUEST message sent as a broadcast?

The client may have received offers from multiple servers, and the broadcast serves to implicitly decline those other offers.

What process is used in ICMPv6 for a host to verify that an IPv6 address is unique before configuring it on an interface?

DAD

Match the DHCP message types to the order of the DHCPv4 process. (Not all options are used.)

DHCPDISCOVER DHCPOFFER DHCPREQUEST DHCPACK

Which message does an IPv4 host use to reply when it receives a DHCPOFFER message from a DHCP server?

DHCPREQUEST

Which destination IP address is used when an IPv6 host sends a DHCPv6 SOLICIT message to locate a DHCPv6 server?

FF02::1:2

Which command will allow a network administrator to check the IP address that is assigned to a particular MAC address?

Router# show ip dhcp binding

In which alternative to DHCPv6 does a router dynamically provide IPv6 configuration information to hosts?

SLAAC

After booting, a client receives an ICMPv6 RA message with the M flag set to 0 and the O flag set to 1. What does this indicate?

The client should automatically configure an IPv6 address and then contact a DHCPv6 server for more information.

An administrator has configured a DHCPv4 relay router and issued these commands: Router(config)# interface g0/0 Router(config-if)# ip address 10.0.1.1 255.255.255.0 Router(config-if)# no shutdown Router(config-if)# exit Router(config)# ip dhcp pool RELAY Router(dhcp-config)# end The clients are not receiving IP parameters from the DHCPv4 server. What is a possible cause?

The ip helper-address command is missing.

Refer to the exhibit. PC-A is unable to receive an IPv6 address from the stateful DHCPv6 server. What is the problem?

The ipv6 dhcp relay command should be applied to interface Gig0/0.

Refer to the exhibit. A network administrator is configuring a router for DHCPv6 operation. Which conclusion can be drawn based on the commands?

The router is configured for stateless DHCPv6 operation.

Which command should be configured on a router interface to set the router as a stateful DHCPv6 client?

ipv6 address dhcp

What is the most likely scenario in which the WAN interface of a router would be configured as a DHCP client to be assigned a dynamic IP address from an ISP?

it is a SOHO or home broadband router.

Fill in the blank. Do not abbreviate. An administrator is troubleshooting a DHCPv4 issue on a router. By issuing the debug ip dhcp ___________ command, the administrator can watch, in real time, the IP address assignments that are performed by the router.
