Modules 6 - 8

A company is considering updating the campus WAN connection. Which two WAN options are examples of the private WAN architecture? (Choose two.)

• cable
• digital subscriber line
• Ethernet WAN
• leased line
• municipal Wi-Fi

A network administrator wants to examine the active NAT translations on a border router. Which command would perform the task?

• Router# clear ip nat translations
• Router# debug ip nat translations
• Router# show ip nat statistics
• Router# show ip nat translations

How is “tunneling” accomplished in a VPN?

• A dedicated circuit is established between the source and destination devices for the duration of the connection.
• All packets between two hosts are assigned to a single physical medium to ensure that the packets are kept private.
• New headers from one or more VPN protocols encapsulate the original packets.
• Packets are disguised to look like other types of traffic so that they will be ignored by potential attackers.

In NAT terms, what address type refers to the globally routable IPv4 address of a destination host on the Internet?

• inside global
• inside local
• outside global
• outside local

Open the PT Activity. Perform the tasks in the activity instructions and then answer the question. What problem is causing PC-A to be unable to communicate with the Internet?

• The access list used in the NAT process is referencing the wrong subnet.
• The ip nat inside source command refers to the wrong interface.
• The NAT interfaces are not correctly assigned.
• The static route should not reference the interface, but the outside address instead.
• This router should be configured to use static NAT instead of PAT.

Refer to the exhibit. A network administrator has configured R2 for PAT. Why is the configuration incorrect?

• NAT-POOL2 is bound to the wrong ACL
• The ACL does not define the list of addresses to be translated.
• The overload keyword should not have been applied.
• The static NAT entry is missing

Refer to the exhibit. A network administrator has just configured address translation and is verifying the configuration. What three things can the administrator verify? (Choose three.)

• A standard access list numbered 1 was used as part of the configuration process.
• Address translation is working.
• One port on the router is not participating in the address translation.
• The name of the NAT pool is refCount.
• Two types of NAT are enabled.

Refer to the exhibit. A network administrator is viewing the output from the command show ip nat translations. Which statement correctly describes the NAT translation that is occurring on router RT2?

• The traffic from a source IPv4 address of 192.0.2.88 is being translated by router RT2 to reach a destination IPv4 address of 192.168.254.253.
• The traffic from a source IPv4 address of 192.168.2.20 is being translated by router RT2 to reach a destination IPv4 address of 192.0.2.254.
• The traffic from a source IPv4 address of 192.168.254.253 is being translated to 192.0.2.88 by means of static NAT.
• The traffic from a source IPv4 public address that originates traffic on the internet would be able to reach private internal IPv4 addresses.

Refer to the exhibit. Based on the output that is shown, what type of NAT has been implemented?

• dynamic NAT with a pool of two public IP addresses
• PAT using an external interface
• static NAT with a NAT pool
• static NAT with one entry

Refer to the exhibit. From the perspective of R1, the NAT router, which address is the inside global address?

• 192.168.0.1
• 192.168.0.10
• 209.165.200.225
• 209.165.200.254
