*the router is intended to be used as a solo gateway *This is an ISP requirement

what are the 3 steps in order to configure a router as a DHCPv4 server?

1. Excluding IPv4 address 2. configure a DHCP pool 3. define the default gateway router

A network administrator is implementing DHCPv6 for the company. The administrator configures a router to send RA messages with M flags as 1 by using the interface command ipv6 nd managed-config-flag. What effect will this configuration have on the operation of clients?

clients must use all configuration information that is provided by a DHCPv6 server

As a DHCPv4 client lease is about to expire, what is the message that the client sends the DHCP server?

DHCPREQUEST

A company implements the stateless DHCPv6 method for configuring IPv6 addresses on employee workstations. After a workstation receives messages from multiple DHPCv6 servers to indicate their availability for DHCPv6 service, which message does it send to a server for configuration information?

DHCPv6 INFORMATION-REQUEST

How does an IPv6 client ensure that it has a unique address after it configures its IPv6 address using the SLAAC allocation method?

ICMPv6

a network administrator configures a router to send RA messages with M flags as 0 and O flag as 1. Which statement describes the effect of this configuration when a PC tries to configure its IPv6 address?

It should use information that is contained in the RA message and contact a DHCPv6 server for additional information

an administrator issues the commands: Router(config)#interface g0/1 Router (config-if)# ip address dhcp what is the administrator trying to achieve?

configuring the router to obtain IP parameters from DHCPv4 server

What is the command to exclude the first fifteen usable IP addresses from a DHCPv4 address pool of the network 10.0.15.0/24

Router(config)# ip dhcp excluded-address 10.0.15.1 10.0.15.15

Refer to the exhibit. Based on the output that is shown, what kind of IPv6 addressing is being configured

Stateless DHCPv6

refer to the exhibit. A network administrator is implementing the stateless DHCPv6 operation for the company. Clients are configuring IPv6 addresses as expected. However, the clients are not getting the DNS server address and the domain name information configured in the DHCP pool. What could be the cause of the problem.

The router configured for SLAAC operation

Refer to the exhibit. what should be done to allow PC-A to receive an IPv6 address from the server

add the ipv6 dhcp relay command to interface Fa0/0

Which DHCPv4 message will a client send to accept an IPv4 address that is offered by a DHCP server?

broadcast DHCPREQUEST

Which address does a DHCPv4 server target when sending a DHCPOFFER message to a client that makes an address request

client hardware address

Which set of commands will configure a router as a DHCP server that will assign IPv4 addresses to the 192.168.100.0/23 LAN while reserving the first 10 and the last addresses for static assignment?

ip dhcp excluded-address 192.168.100.1 192.168.110.10 ip dhcp excluded-address 192.168.101.254 ip dhcp pool LAN-pool-100 network 192.168.100.0 255.255.254.0 default-router 192.168.100.1

A host on the 10.10.100.0/24 LAN is not being assigned an IPv4 address by an enterprise DHCP server with the address 10.10.200.10/24. What is the best way for the network engineer to resolve this problem?

issue the command ip helper-address 10.10.200.10 on the router interface that is the 10.10.100.0/24 gateway

what are the advantages of configuring a cisco router as a relay agent?

it can provide relay services for multiple UDP services

An administrator wants to configure hosts automatically assign IPv6 addresses to themselves by the use of Router Advertisement messages, but also to obtain the DNS server address from a DHCPv6 server. Which addres assignment method should be configured?

stateless DHCPv6

what is used in the EUI-64 process to create an IPv6 interface ID on an IPv6 enabled interface

the MAC address of the IPv6 enabled interface*

a company uses the SLAAC method to configure IPv6 addresses for the employee workstations. Which address will a client use as its default gateway?

the link-local address of the router interface that is attatched to the network

refer to the exhibit. A network administrator is implementing stateful DHCPv6 operation for the company. However, the clients are not using the prefix and prefix-length information that is configured in the DHCP pool. The administrator issues a show ipv6 interface command. What could be the cause of the problem?

the router is configured for stateless DHCPv6 operation

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
