CCNA 2 Chapter 10 v5.03

1. 1Refer 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?

   

   1. AThe GigabitEthernet interface is not activated.
   2. BThe router is configured for SLAAC operation.
   3. CThe DNS server address is not on the same network as the clients are on.
   4. DThe clients cannot communicate with the DHCPv6 server, evidenced by the number of active clients being 0.
2. 2Which DHCPv4 message will a client send to accept an IPv4 address that is offered by a DHCP server?

   1. Aunicast DHCPACK
   2. Bbroadcast DHCPACK
   3. Cunicast DHCPREQUEST
   4. Dbroadcast DHCPREQUEST
3. 3What is the reason why the DHCPREQUEST message is sent as a broadcast during the DHCPv4 process?

   2. Bto notify other hosts not to request the same IP address
   3. Cfor hosts on other subnets to receive the information
   4. Dfor routers to fill their routing tables with this new information

   2. BDHCPOFFER
   3. CDHCPREQUEST
   4. DDHCPACK
5. 5What is an advantage of configuring a Cisco router as a relay agent?

   1. AIt will allow DHCPDISCOVER messages to pass without alteration.
   2. BIt can forward both broadcast and multicast messages on behalf of clients.
   3. CIt can provide relay services for multiple UDP services.
   4. DIt reduces the response time from a DHCP server.
6. 6Which set of commands will configure a router as a DHCP server that will assign IPv4 addresses to the 192.168.100.0/23 LAN while reserving the first 10 and the last addresses for static assignment?
