- C. no mask
- D. block-size Discuss
- 6. 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.

More questions
Correct Answer: show ip nat statistics
Explanation:
The
show ip nat statistics command displays a summary of the NAT configuration as well as counts of active translation types, hits to an existing mapping, misses (causing an attempt to create a mapping), and expired translations.
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 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: 1, 3 and 5
Explanation:
You can configure NAT three ways on a Cisco router: static, dynamic, and NAT Overload (PAT).
Correct Answer: prefix-length
Explanation:
Instead of the
netmask command, you can use the
prefix-length <length> statement.
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: 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: 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.
Correct Answer: These addresses are meant for nonrouting purposes, but they are almost globally unique so it is unlikely they will have an address overlap.
Explanation:
These addresses are meant for nonrouting purposes like link-local, but they are almost globally unique so it is unlikely they will have an address overlap. Unique local addresses were designed as a replacement for site-local addresses.
