The cisco router will exclude 15

After a host has generated an IPv6 address by using the DHCPv6 or SLAAC process, how does the host verify that the address is unique and therefore usable?

The host sends an ICMPv6 neighbor solicitation message to the DHCP or SLAAC-learned address and if no neighbor advertisement is returned. The address Is considered unique

A company uses the SLAAC method to configure IPv6 addresses for the employee workstations. Which address will a client use as its default gateway?

The link-local address off the router interface that is attached to the network

Refer 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?

The router is configured for SLAAC operation

Refer to the exhibit. A network administrator is configuring a router for DHCPv6 operation. Which conclusion can be drawn based on the commands?

The router is configured for stateless DHCPv6 operation

Refer to the exhibit. A network administrator is configuring a router as a DHCPv6 server. The administrator issues a show ipv6 dhcp pool command to verify the configuration. Which statement explains the reason that the number of active clients is 0?

The state is not maintained by the DHCPv6 server under stateless DHCPv6 operation

Which statement is true about DCHP operation?

When a device that is configured to use DHCP boots, the client broadcasts a DHCPDISCOVER message to identify any available DHCP servers on the network

What is a result when the DHCP servers are not operational in a network?

Workstations are assigned with IP addresses in the 169.254.0.0/16

The address pool of a DHCP server is configured with 10.19.44.0/24 the network administrator reserves 6 IP addresses for servers. How many IP addresses are left in the pool to be assigned to other hosts?

248

A client device on an Ethernet segment needs an IP address in order to communicate on the network. A DHCP server with IP address 192.168.1.1 has been configured and enabled on the network. How will a client device obtain a usable IP address for this network?

Send a DHCPDISCOVER message to physical address FF-FF-FF-FF-FF-FF

Which FHRP implementation is a nonproprietary IPv4-only election protocol with limited scalability?

VRRPv2

Refer to the exhibit. What should be done to allow PC-A to receive an IPv6 address from the DHCPv6 server?

Add the ipv6 dhcp relay command to interface f0/0

Which protocol automates assignment of IP addresses on a network, and which port number does it use? (Choose two.)

DHCP 67

A host PC is attempting to lease an address through DHCP. What message is sent by the server to let the client know it is able to use the provided IP information?
