RSE Chapter 8 Exam
Refer to the exhibit. What should be done to allow PC-A to receive an IPv6 address from the DHCPv6 server?
Add the ipv6 dhcp relay command to interface Fa0/0
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 DHCPv6 servers to indicate their availability for DHCPv6 service, which message does it send to a server for configuration information?
DHCPv6 INFORMATION-REQUEST
What two methods can be used to generate an interface ID by an IPv6 host that is using SLAAC? (Choose two.)
EUI-64 and random generation
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?
FF-FF-FF-FF-FF-FF and 255.255.255.255
What is a advantage of configuring a Cisco router as a relay agent?
It can provide relay services for multiple UDP services
How does an IPv6 client ensure that it has a unique address after it configures its IPv6 address using the SLAAC allocation method?
It sends an ICMPv6 Neighbor Solicitation message with the IPv6 address as the target IPv6 address
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?
It should use the information that is contained in the RA message and contact a DHCPv6 server for additional information
What is the result of a network technician issuing the command ip dhcp excluded-address 10.0.15.1 10.0.15.15 on a Cisco router?
The Cisco router will exclude 15 IP addresses from being leased to DHCP clients
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 is configured for SLAAC 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 stateless DHCPv6 operation
Under which two circumstances would a router usually be configured as a DHCPv4 client? (Choose two.)
The router is intended to be used as a SOHO gateway and This is an ISP requirement
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
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 a DHCPv4 server
Which is a DHCPv4 address allocation method that assigns IPv4 addresses for a limited lease period?
dynamic allocation
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
excluded-address 10.0.15.1 10.0.15.15
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?
stateless DHCPv6
Refer to the exhibit. Based on the output that is shown, what kind of IPv6 addressing is being 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 attached to the network
