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.)

Router R1, a branch router, connects to the Internet using DSL. The engineer plans to use a
configuration with a dialer interface. The answers list a feature and interface on which the
feature could be configured. Which combinations accurately describe the interface under
which a feature will be configured?

Router R1, a branch router, connects to the Internet using DSL. Some traffic flows through a
GRE and IPsec tunnel, over the DSL connection, and into the core of an Enterprise network.
The branch also allows local hosts to communicate directly with public sites in the Internet
over this same DSL connection. Which of the following answers defines how the branch NAT
config avoids performing NAT for the Enterprise directed traffic but does perform NAT for the
Internet-directed traffic?

Router R1, a branch router, connects to the Internet using DSL. Some traffic flows through a
GRE and IPsec tunnel, over the DSL connection, destined for an Enterprise network. Which
of the following answers best describes the router’s logic that tells the router, for a given
packet, to apply GRE encapsulation to the packet?

Which of the following must match for two directly connected routers running OSPF to
establish a neighbor adjacency? (Select 2 choices.)

An engineer is trying to summarize the following networks using the “ip summary-address
eigrp” command:
10.8.88.0/25
10.8.89.48/29
10.8.64.96/27
Which network and subnet mask below would be the smallest EIGRP summary address to
include all three subnets?
