An enterprise has plans to start adding IPv6 support. The initial deployment requires support
from some IPv6-only devices that need to access servers that support only IPv4. Which of
the following tools would be most appropriate?

A client host uses IPv4 to communicate with one server and IPv6 to communicate with
another. Which of the following IPv6 coexistence features is likely at work on the host?

The following configuration exists on a router on one end of an IPv6 tunnel. Which type of
tunnel is created by this configuration?
interface loopback 1
ip address 1.1.1.1 255.255.255.255
interface tunnel 2
ipv6 address 2000::1::/64
tunnel source loopback 1
tunnel destination 2.2.2.2
tunnel mode ipv6ip
ipv6 eigrp 1

An engineer is reviewing another engineer’s sample configuration for a GRE tunnel used to
pass IPv6 traffiC. The tunnel has not yet been configured on the router. Which of the
following commands is not required for the configuration to pass IPv6 traffic?

Which of the following IPv6 tunneling mechanisms support IPv6 IGP routing protocols?
(Choose two.)

The following configuration exists on a router on one end of an IPv6 tunnel. Although the
configuration added so far is correct, the configuration is incomplete.
Which type of tunnel is most likely to be intended by the network engineer?
interface loopback 1
ip address 192.168.1.1 255.255.255.255
interface tunnel 2
ipv6 address 2002:C0A8:101::1/64
tunnel source loopback 1

The answers each list a tunnel method and two consecutive IPv6 address quartets. Which
answers identify a tunneling method that relies on an IPv4 address to be embedded into an
IPv6 address, within the correct quartets listed? (Choose two.)

Router R1 uses MAC address 1111.1111.1111 for its Fa0/0 interface. An engineer sees the
following configuration in the output of a show running-config command. Then, the engineer
issues a show ipv6 interface brief command. What global unicast IPv6 address does this
command display for interface tunnel 1?
interface loopback 1
ip address 192.168.1.1 255.255.255.255
interface tunnel 1
tunnel source loopback 1
tunnel destination 192.168.1.2
tunnel mode ipv6ip isatap
ipv6 address 2000::/64 eui-64

Router R1 sits at an Enterprise branch office, using the Internet for its only connectivity back
to the rest of the EnterprisE. Which of the following is not a benefit of using an IPsec tunnel
for packets sent through the Internet, between R1 and the rest of the
Enterprise?

Router R1 sits at an Enterprise branch office, using both the Internet and a leased line to
another Enterprise router for its two connectivity options back into the rest of the Enterprise
network. The engineer planning for this branch decided to use the leased line for all
Enterprise traffic, unless it fails, in which case the Internet connection should be used to
pass traffic to the Enterprise. Which of the following is most likely to be useful on the branch
router? (Choose two.)
