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.

   3. Cfor hosts on other subnets to receive the information

   3. CIt can provide relay services for multiple UDP services.
   4. DIt reduces the response time from a DHCP server.
