    • unicast DHCPACK
    • broadcast DHCPACK
    • unicast DHCPREQUEST
    • broadcast DHCPREQUEST
  2. 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
  3. Which is a DHCPv4 address allocation method that assigns IPv4 addresses for a limited lease period?

    • to notify other DHCP servers on the subnet that the IP address was leased
    • to notify other hosts not to request the same IP address
    • for hosts on other subnets to receive the information
    • for routers to fill their routing tables with this new information

    • configuring the router to act as a DHCPv4 server
    • configuring the router to obtain IP parameters from a DHCPv4 server
    • configuring the router to act as a relay agent
    • configuring the router to resolve IP address conflicts
  7. Under which two circumstances would a router usually be configured as a DHCPv4 client? (Choose two.)

  8. A network engineer is troubleshooting hosts on a LAN that are not being assigned an IPv4 address from a DHCP server after a new Ethernet switch has been installed on the LAN. The configuration of the DHCP server has been confirmed as correct and the clients have network connectivity to other networks if a static IP address is configured on each one. What step should the engineer take next to solve the issue?

    • Issue the ipconfig/release command on each client.
    • Issue the show ip dhcp binding command on the switch.
    • Confirm that ports on the Layer 2 LAN switch are configured as edge ports.
    • Issue the show interface command on the router to confirm that the LAN gateway is operational.

    • Issue the command ip helper-address 10.10.200.10 on the router interface that is the 10.10.100.0/24 gateway.
    • Issue the command default-router 10.10.200.10 at the DHCP configuration prompt on the 10.10.100.0/24 LAN gateway router.
    • Issue the command ip helper-address 10.10.100.0 on the router interface that is the 10.10.200.0/24 gateway.
    • Issue the command network 10.10.200.0 255.255.255.0 at the DHCP configuration prompt on the 10.10.100.0/24 LAN gateway router.
  10. A company uses the method SLAAC to configure IPv6 addresses for the workstations of the employees. A network administrator configured the IPv6 address on the LAN interface of the router. The interface status is UP. However, the workstations on the LAN segment did not obtain the correct prefix and prefix length. What else should be configured on the router that is attached to the LAN segment for the workstations to obtain the information?​

    • R1(config-if)# ipv6 enable
    • R1(config)# ipv6 unicast-routing
    • R1(config-if)# ipv6 nd other-config-flag

    • the global unicast address of the router interface that is attached to the network
  12. 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.
  13. 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 REQUEST
    • DHCPv6 ADVERTISE
    • DHCPv6 INFORMATION-REQUEST

  17. 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?

    • Clients must use the information that is contained in RA messages.
    • Clients must use all configuration information that is provided by a DHCPv6 server.
    • Clients must use the prefix and prefix length that are provided by a DHCPv6 server and generate a random interface ID.
    • Clients must use the prefix and prefix length that are provided by RA messages and obtain additional information from a DHCPv6 server.

One thought on “CCNA 2 Chapter 10 Exam Answer v5 & v5.02 2015 (100%)

  1. # 23 is incorrect.
    ipv6 address dhcp is a stetefull command, not stateless.
    ipv6 address autoconfig is a Stateless command, not statefull.

    You have them flipped into the WRONG position.
