CCNA 2 Chapter 8

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

• unicast DHCPACK
• broadcast DHCPACK
• unicast DHCPREQUEST
• broadcast DHCPREQUEST

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
• both MAC and IPv4 addresses of the DHCP server
• MAC address of the DHCP server and 255.255.255.255
• FF-FF-FF-FF-FF-FF and IPv4 address of the DHCP server

Which is a DHCPv4 address allocation method that assigns IPv4 addresses for a limited lease period?

• manual allocation
• pre-allocation
• automatic allocation
• dynamic allocation

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

• client IP address
• client hardware address
• gateway IP address
• broadcast MAC address

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

• DHCPDISCOVER
• DHCPOFFER
• DHCPREQUEST
• DHCPACK

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

• It will allow DHCPDISCOVER messages to pass without alteration.
• It can forward both broadcast and multicast messages on behalf of clients.
• It can provide relay services for multiple UDP services.
• It reduces the response time from a DHCP server.

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.

• The administrator needs the router to act as a relay agent.

• The router is meant to provide IP addresses to the hosts.

• This is an ISP requirement.

• The router has a fixed IP address

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 all-routers multicast address
• the link-local address of the router interface that is attached to the network
• the unique local address of the router interface that is attached to the network
• the global unicast address of the router interface that is attached to the network

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 contact a DHCPv6 server for all the information that it needs.
• It should use the information that is contained in the RA message exclusively.
• It should use the information that is contained in the RA message and contact a DHCPv6 server for additional information
• It should contact a DHCPv6 server for the prefix, the prefix-length information, and an interface ID that is both random and unique.

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 SOLICIT
• DHCPv6 REQUEST
• DHCPv6 ADVERTISE
• DHCPv6 INFORMATION-REQUEST
