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
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.

1. What command is used to stop RIP routing updates from exiting out an interface but still allow the interface to receive RIP route updates?
The best answers, the ones you need to remember, are that either an access control list is filtering the Telnet session or the VTY password is not set on the remote device.
4. Acknowledgments, sequencing, and flow control are characteristics of which OSI layer?
A reliable Transport layer connection uses acknowledgments to make sure all data is transmitted and received reliably. A reliable connection is defined by a virtual circuit that uses acknowledgments, sequencing, and flow control, which are characteristics of the Transport layer (layer 4).
5. How many non-overlapping channels are available with 802.11g?
Correct Answer: Issue the show cdp neighbors detail command on the router connected to the switch.
Explanation:
Although option A is certainly the "best" answer, unfortunately option D will work just fine and your boss would probably prefer you to use the
show cdp neighbors detail command.
7. What is the frequency range of the IEEE 802.11a standard?
A /27 (255.255.255.224) is 3 bits on and 5 bits off. This provides 8 subnets, each with 30 hosts. Does it matter if this mask is used with a Class A, B, or C network address? Not at all. The number of host bits would never change.
