CCNA2 MODULE 7

A DHCP-enabled client PC has just booted. During which two steps will the client PC use broadcast messages when communicating with a DHCP server? (Choose two.)

• • DHCPNAK

• • DHCPREQUEST

• • DHCPOFFER

• • DHCPDISCOVER

An administrator issues the commands:

Router(config)# interface g0/1

Router(config-if)# ip address dhcp

• • configuring the router to act as a DHCPv4 server

• • configuring the router to act as a relay agent

• • configuring the router to resolve IP address conflicts

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

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

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

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

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

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

Which DHCP IPv4 message contains the following information?

• DHCPDISCOVER

• • DHCPOFFER

• • DHCPACK

• • DHCPREQUEST

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

• • DHCPDISCOVER unicast message

• • DHCPDISCOVER broadcast message

• • DHCPOFFER unicast message

• DHCPACK unicast message

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

• • DHCPDISCOVER

• • DHCPREQUEST

• • DHCPOFFER

• • DHCPACK

What is the destination IP address when an IPv4 host sends a DHCPDISCOVER message?

• • 192.168.1.1

• • 255.255.255.255

• • 0.0.0.0

• • 224.0.0.1

If more than one DHCP server is available on the local network, in which order will DHCP messages be sent between a host and a DHCP server?

• • acknowledgment, request, offer, discover

• • request, discover, offer, acknowledgment

• • discover, offer, request, acknowledgment

• • request, acknowledgment, discover, offer

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 configured as a DHCP server.

• • The router is also the gateway for a LAN.

• • It is a SOHO or home broadband router.

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

• manual allocation

• • dynamic allocation

• pre-allocation

• • automatic allocation
