Options- A. NAT Fast
- B. NAT Static
- C. NAT Overload
- D. Overloading Static
- Correct Answer
- NAT Overload
ExplanationAnother term for port address translation is NAT Overload because that is the command used to enable port address translation. - 1. Which of the following is considered to be the destination host after translation?
Options- A. Inside local
- B. Outside local
- C. Inside global
- D. Outside global Discuss
- 2. When creating a pool of global addresses, which of the following can be used instead of the netmask command?
Options- A. / (slash notation)
- B. prefix-length
- C. no mask
- D. block-size Discuss
- 3. Which are considered the methods of NAT?

- Overload
Options- A. 1 and 6
- B. 3 only
- C. 1, 3 and 5
- D. All of the above Discuss
- 4. Which command would you place on interface on a private network?
Options- A. ip nat inside
- B. ip nat outside
- C. ip outside global
- D. ip inside local Discuss
- 5. Which command will clear all the translations active on your router?
Options- A. show ip nat translations
- B. show ip nat statistics
- C. debug ip nat

- 6. Which command would you place on interface connected to the Internet?
Options- A. ip nat inside
- B. ip nat outside
- C. ip outside global
- D. ip inside local Discuss
- 7. Which of the following is true when describing an anycast address?
Options- A. Packets addressed to a unicast address are delivered to a single interface.
- B. Packets are delivered to all interfaces identified by the address. This is also called one-to-many addresses.
- C. This address identifies multiple interfaces and the anycast packet is only delivered to one address. This address can also be called one-to-one-of-many.
- D. These addresses are meant for nonrouting purposes, but they are almost globally unique so it is unlikely they will have an address overlap. Discuss
- 8. Which of the following is true when describing a link-local address?
Options- A. Packets addressed to a unicast address are delivered to a single interface.
- B. These are your typical publicly routable addresses, just like a regular publicly routable address in IPv4.
- C. These are like private addresses in IPv4 in that they are not meant to be routed.
- D. These addresses are meant for nonrouting purposes, but they are almost globally unique so it is unlikely they will have an address overlap. Discuss
- 9. Which statement(s) about IPv6 addresses are true?
- Leading zeros are required.
- Two colons (::) are used to represent successive hexadecimal fields of zeros.
- Two colons (::) are used to separate fields.
- A single interface will have multiple IPv6 addresses of different types.
Options- A. 1 and 3
- B. 2 and 4
- C. 1, 3 and 4
- D. All of the above Discuss
- 10. Which of the following is true when describing a unicast address?

Correct Answer: Outside global
Explanation:
The host on the global network after translation is considered to be an outside global host.
Correct Answer: prefix-length
Explanation:
Instead of the
netmask command, you can use the
prefix-length <length> statement.
Correct Answer: 1, 3 and 5
Explanation:
You can configure NAT three ways on a Cisco router: static, dynamic, and NAT Overload (PAT).
Correct Answer: ip nat inside
Explanation:
As in access-lists, you must configure your interfaces before NAT will provide any translations. On the inside networks you would use the command
ip nat inside. On the outside interface, you will use the command
ip nat outside.
Correct Answer: clear ip nat translations *
Explanation:
The command
clear ip nat translations * will clear all the active NAT entries in your translation table.
Correct Answer: ip nat outside
Explanation:
As in access-lists, you must configure your interfaces before NAT will provide any translations. On the inside networks you would use the command
ip nat inside. On the outside interface, you will use the command
ip nat outside.
Correct Answer: This address identifies multiple interfaces and the anycast packet is only delivered to one address. This address can also be called one-to-one-of-many.
Explanation:
Anycast addresses identify multiple interfaces, which is the same as multicast; however, the big difference is that the anycast packet is only delivered to one address, the first one it finds defined in the terms of routing distance. This address can also be called one-to-one-of-many.
Correct Answer: These are like private addresses in IPv4 in that they are not meant to be routed.
Explanation:
Link-local addresses are meant for throwing together a temporary LAN for meetings or a small LAN that is not going to be routed but needs to share and access files and services locally.
Correct Answer: 2 and 4
Explanation:
In order to shorten the written length of an IPv6 address, successive fields of zeros may be replaced by double colons. In trying to shorten the address further, leading zeros may also be removed. Just as with IPv4, a single device's interface can have more than one address; with IPv6 there are more types of addresses and the same rule applies. There can be link-local, global unicast, and multicast addresses all assigned to the same interface.
Correct Answer: Packets addressed to a unicast address are delivered to a single interface.
Explanation:
Packets addressed to a unicast address are delivered to a single interface. For load balancing, multiple interfaces can use the same address.
