SWRE Unit 7 and 8 pt2

What action does a DHCPv4 client take if it receives more than one DHCPOFFER from multiple DHCP servers?

• • It sends a DHCPREQUEST that identifies which lease offer the client is accepting.

• • It sends a DHCPNAK and begins the DHCP process over again.

• • It discards both offers and sends a new DHCPDISCOVER.

• • It accepts both DHCPOFFER messages and sends a DHCPACK.

Consider that the main power has just been restored. PC3 issues a broadcast IPv4 DHCP request. To which port will SW1 forward this request?​

• • to Fa0/1, Fa0/2, Fa0/3, and Fa0/4

• • to Fa0/1, Fa0/2, and Fa0/3 only

• • to Fa0/1 only​

• • to Fa0/1, Fa0/2, and Fa0/4 only​

• • to Fa0/1 and Fa0/2 only

A network administrator has configured a router for stateless DHCPv6 operation. However, users report that workstations are not receiving DNS server information. Which two router configuration lines should be verified to ensure that stateless DHCPv6 service is properly configured? (Choose two.)

• • The domain-name line is included in the ipv6 dhcp pool section.

• • The dns-server line is included in the ipv6 dhcp pool section.

• • The ipv6 nd other-config-flag is entered for the interface that faces the LAN segment.

• • The address prefix line is included in the ipv6 dhcp pool section.

• • The ipv6 O managed-config-flag is entered for the interface that faces the LAN segment.

What is the effect of entering the ip dhcp snooping limit rate 6 configuration command on a switch?

• • It displays the IP-to-MAC address associations for switch interfaces.

• • It enables port security globally on the switch.

• • It restricts the number of discovery messages, per second, to be received on the interface.

• • It dynamically learns the L2 address and copies it to the running configuration.

A network administrator is configuring the router R1 for IPv6 address assignment. Based on the partial configuration, which IPv6 global unicast address assignment scheme does the administrator intend to implement?

• • stateful

• • stateless

• • manual configuration

• • SLAAC

What Broadcast message does a host send to initiate the DHCP process

• DHCPACK

• DHCPDISCOVER

• DHCPPACK

• DHCPREQUEST

What command will enable a router to begin sending messages that allow it to configure a link-local address without using an IPv6 DHCP server?

• • a static route

• 
  the ipv6 unicast-routing command

• • the ipv6 route ::/0 command

• 
  the ip routing command

What network attack seeks to create a DoS for clients by preventing them from being able to obtain a DHCP lease?

• 
  IP address spoofing

• • CAM table attack

• • DHCP starvation

• • DHCP spoofing
