An administrator has configured a dhcpv4 relay router and issued these commands:

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 request an IPv6 address directly from a DHCPv6 server.

The client should automatically configure an IPv6 address without contacting a DHCPv6 server.

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

The client should be statically configured with an IPv6 address because the local router does not support autoconfiguration.

Question 22 pts

Match the DHCP message types to the order of the stateful DHCPv6 process when a client first connects to an IPv6 network. (Not all options are used.)

Step 1

                                                                                                   DDHCPV6 SOLICIT

Step 2

                                                                                                   DHCPV6 ADVERTISE

Step 3

                                                                                                   DHCPV6 REQUEST

Step 4

                                                                                                   DHCPV6 REPLY

Question 42 pts

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 pool cannot be named 'RELAY'.

The router is configured as a DHCPv4 client.

The IP address is incorrect for the subnet mask that is used.

The ip helper-address command is missing.

Question 52 pts

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

Router# show ip dhcp pool

Router# show ip dhcp server statistics

Router# show running-config I section_dhcp

Question 62 pts

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?

There is a web server for public access on the LAN that is attached to the router.

The router is also the gateway for a LAN.

It is a SOHO or home broadband router.

The router is configured as a DHCP server.

Question 72 pts

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

DHCPACK

DHCPDISCOVER

DHCPOFFER

DHCPREQUEST


Flag this Question

Question 82 pts

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

The client does not yet know the IP address of the DHCP server that sent the offer.

The DHCP server may be on a different subnet, so the request must be sent as a broadcast.

The client does not have a MAC address assigned yet, so it cannot send a unicast message at Layer 2.

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

Question 92 pts

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

ARP

EUI-64

ICMPv6

SLAAC

Question 102 pts

An administrator has configured a dhcpv4 relay router and issued these commands:


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

The DHCPv6 server name is ACAD_CLASS.

The router is configured for stateful DHCPv6 operation, but the DHCP pool configuration is incomplete.

What kind of message is sent by a DHCPv4 client requesting an IP address?

DHCPv4 Operation The client transmits a DHCPDISCOVER message on its local network when it boots or senses an active network connection. Because the client has no way of knowing the subnet to which it belongs, the DHCPDISCOVER message is an IPv4 broadcast (destination IPv4 address of 255.255. 255.255).

What command makes DHCP pool?

Create a new DHCP pool with the ip dhcp pool NAME command. Define a subnet that will be used to assign IP addresses to hosts with the network SUBNET SUBNET_MASK command. Define the default gateway with the default-router IP command. Define the DNS server with the dns-server IP address command.
