P4_R&S_Chapter 8 - Test

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)# ipv6 dhcp pool < name of the pool >

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

• R1(config)# ipv6 unicast-routing

• R1(config-if)# ipv6 enable

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.

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

• Configure the ipv6 nd managed-config-flag command on interface Fa0/1.

• Add the ipv6 dhcp relay command to interface Fa0/0.

• Change the ipv6 nd managed-config-flag command to ipv6 nd other-config-flag .

• Add the IPv6 address 2001:DB8:1234:5678::10/64 to the interface configuration of the DHCPv6 server.

Refer to the exhibit. PC-A is unable to receive an IPv6 address from the stateful DHCPv6 server. What is the problem?

• The ipv6 dhcp relay command should be applied to interface Gig0/0.

• The ipv6 nd managed-config-flag should be applied to interface Gig0/1.

• The ipv6 nd managed-config-flag command should be ipv6 nd other-config-flag .

• The ipv6 dhcp relay command should use the link-local address of the DHCP server.

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 GigabitEthernet interface is not activated.

• The DNS server address is not on the same network as the clients are on.

• The router is configured for SLAAC operation.

• The clients cannot communicate with the DHCPv6 server, evidenced by the number of active clients being 0.

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 default gateway address is not provided in the pool.

• No clients have communicated with the DHCPv6 server yet.

• The IPv6 DHCP pool configuration has no IPv6 address range specified.

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

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 all-routers multicast address

• the link-local address of the router interface that is attached to the network

• the unique local address of the router interface that is attached to the network

• the global unicast address of the router interface that is attached to the network

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

• The DHCPv6 server name is ACAD_CLASS.

• Clients would configure the interface IDs above 0010.

• The router is configured for stateful DHCPv6 operation, but the DHCP pool configuration is incomplete.

• The router is configured for stateless DHCPv6 operation.

Refer to the exhibit. Based on the output that is shown, what kind of IPv6 addressing is being configured?

• SLAAC

• stateful DHCPv6

• stateless DHCPv6

• static link-local

Which address type is automatically created by default on a host interface when no RAs are received?

• link-local address

• global unicast address

• MAC address
