2 While configuring a router using RIPng and dual-stack technology with
IPv4 and IPv6, the administrator receives an error message when
inputting IPv4 routes. What could cause the error message?
IPv4 is not compatible with RIPng
RIPng is incompatible with dual-stack technology.
The router interfaces have been configured with incorrect addresses.
When IPv4 and IPv6 are configured on the same interface, all IPv4
addresses are shut down in favor of the newer technology.

3 Which statement is true about an interface that is configured with the
IPv6 address command?
IPv6 traffic-forwarding is enabled on the interface.
A link-local IPv6 address is automatically configured on the interface.
A global unicast IPv6 address is dynamically configured the interface.
Any IPv4 addresses that are assigned to the interface are replaced with
an IPv6 address.

4 What will be the result of adding the command ip dhcp excluded-
address 172.16.4.1 172.16.4.5 to the configuration of a local router that
has been configured as a DHCP server?
Traffic that is destined for 172.16.4.1 and 172.16.4.5 will be dropped by
the router.
Traffic will not be routed from clients with addresses between 172.16.4.1
and 172.16.4.5.
The DHCP server function of the router will not issue the addresses
between 172.16.4.1 and 172.16.4.5.
The router will ignore all traffic that comes from the DHCP servers with
addresses 172.16.4.1 and 172.16.4.5.

Refer to the exhibit. A host that is connected to Fa0/0 is unable to acquire
an IP address dynamically from the DHCP server. The output of the
debug ip dhcp server command shows "DHCPD: there is no address pool
for 172.16.1.1". What is the problem?
The default router for the 172Network pool is incorrect.
The 172.16.1.1 address is already configured on Fa0/0.
The pool of addresses for the 172Network pool is incorrect.
The ip helper-address command should be implemented on the Fa0/0
interface.

Refer to the exhibit. Which statement is true about the WAN switch
device?
It uses a multiport internetworking device to switch traffic such as Frame
Relay, ATM or X.25 over the WAN.
It provides internetworking and WAN access interface ports that are used
to connect to the service provider network.
It provides termination for the digital signal and ensures connection
integrity through error correction and line monitoring.
It converts the digital signals produced by a computer into voice
frequencies that can be transmitted over the analog lines of the public
telephone network.
