D. Only outgoing traffic can be shaped

E. Both incoming and outgoing traffic can be policed

F. Generally results in fewer TCP retransmissions than traffic policing

G. Generally results in more TCP retransmissions than traffic policing

Here are the answers!

CCNA: B. The config register setting 0x2100 will have the router boot into ROM Monitor mode.

0x2142 will have the router ignore the contents of NVRAM when it boots; that means the starting configuration is ignored.

The default config register setting is 0x2102, which means the router will look in NVRAM for a valid startup configuration file and to Flash for a valid IOS image.

CCENT: A. An address that begins with 127 is reserved for loopbacks, but not for Cisco router loopbacks - you can't assign an address from this range to a Cisco loopback interface.

CCNA Security / ISCW Exam: The Advanced Wizard allow you to configure multiple outside interfaces as well as a DMZ. The Basic Wizard allows neither of these. Additionally, the Advanced Wizard allows you to define your own customized inspection rules, where the Basic Wizard does not.
