excluded-address 10.0.15.1 10.0.15.15

Fill in the blank. Do not abbreviate. Type a command to exclude the first fifteen useable IP addresses from a DHCPv4 address pool of the network 10.0.15.0/24. Router(config)# ip dhcp "___________"

It sends an ICMPv6 Neighbor Solicitation message with the IPv6 address as the target IPv6 address.*

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

The router is intended to be used as a SOHO gateway.* This is an ISP requirement.*

Under which two circumstances would a router usually be configured as a DHCPv4 client? (Choose two.)

Place the options in the following order: [+] Step 2 -> Configure a DHCP pool. [+] Step 1 -> Exclude IP addresses. - not scored - [+] Step 3 ->Define the default gateway router - not scored -

Order the steps of configuring a router as a DHCPv4 server. (Not all options are used.)

DHCPv6 INFORMATION-REQUEST*

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

FF-FF-FF-FF-FF-FF and 255.255.255.255*

A company uses DHCP servers to dynamically assign IPv4 addresses to employee workstations. The address lease duration is set as 5 days. An employee returns to the office after an absence of one week. When the employee boots the workstation, it sends a message to obtain an IP address. Which Layer 2 and Layer 3 destination addresses will the message contain?

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

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

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

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?

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

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

Clients must use all configuration information that is provided by a DHCPv6 server.*

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

The router is configured for stateless DHCPv6 operation.*

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 SLAAC operation.*

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?

stateless DHCPv6*

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

Add the ipv6 dhcp relay command to interface Fa0/0.*

Refer to the exhibit. What should be done to allow PC-A to receive an IPv6 address from the DHCPv6 server?

It can provide relay services for multiple UDP services.*

What is an advantage of configuring a Cisco router as a relay agent?

to notify other DHCP servers on the subnet that the IP address was leased*

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

the MAC address of the IPv6 enabled interface

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

broadcast DHCPREQUEST*

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

client hardware address*

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

ip dhcp excluded-address 192.168.100.1 192.168.100.(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

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?

stateless DHCPv6*

An administrator wants to configure hosts to 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 address assignment method should be configured?

DHCPREQUEST*

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

configuring the router to obtain IP parameters from a DHCPv4 server*

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

one pool* three leases*

Launch PT Hide and Save PT Open the PT Activity. Perform the tasks in the activity instructions and then answer the question. How many IP addresses has the DHCP server leased and what is the number of DHCP pools configured? (Choose two.)

Place the options in the following order: Stateless DHCPv6 [+] enabled in RA messages with the ipv6 nd other-config-flag command [+] clients send only DHCPv6 INFORMATION-REQUEST messages to the server [+] enabled on the client with the ipv6 address autoconfig command Stateful DHCPv6 [#] the M flag is set to 1 in RA messages [#] uses the address command to create a pool of addresses for clients [#] enabled on the client with the ipv6 address dhcp command

Match the descriptions to the corresponding DHCPv6 server type. (Not all options are used.)
