Let's test your knowledge of the default-information originate command, Setup
Mode, and VPNs with these Cisco certification exam practice questions!
CCNA Certification:
What's the main difference between the
default-information originate command with and without the always option? Be
specific.
Answer: Let's use IOS Help to look at our options for this
command.
R1(config)#router ospf 1
R1(config-router)#default-information originate ?
always Always
advertise default route
metric OSPF default metric
metric-type
OSPF metric type for default routes
route-map Route-map reference
The always option allows the router to propagate a default route without
actually having one in its routing table. Without that option, the router must
have a default route in its table in order to advertise one.
CCENT
Certification:
You're using Setup Mode to configure a Cisco router. You
decide halfway through that you'd rather write the configuration at the CLI. How
can you exit Setup Mode and not save the configuration you're in the process of
writing?
Answer: Use the ctrl-c keystroke combination to exit Setup Mode
without saving your configuration. You'll then be placed back at the command
prompt.
CCNA Security Certification / CCNP ISCW Exam:
The SA
state of your VPN is shown as QM_IDLE. Is this good? If not, what do we need to
do to resolve the issue?
Answer: There is no issue - that's what we want
the SA state to be!
CCNP Certification / BSCI Exam:
What command
allows you to add protocols to those forwarded by the ip helper-address command?
And just to review, what protocols are forwarded by the helper-address command?
Answer: Nine common UDP service broadcasts are "helped" by default:
TIME, port 37
TACACS, port 49
DNS, port 53
BOOTP/DHCP Server, port 67
BOOTP/DHCP Client, port 68
TFTP, port 69
NetBIOS name service, port 137
NetBIOS
datagram service, port 138
IEN-116 name service, port 42
You can
use the ip forward-protocol command to add any UDP port number to the list.
To remove protocols from the default list, use the no ip
forward-protocol command.
R1(config)#ip forward-protocol udp 123
R1(config)#no ip forward-protocol udp 137
R1(config)#no ip
forward-protocol udp 138
CCNP Certification / BCMSN Exam:
You've
just enabled password encryption on a Cisco switch. When you attempt to view the
VTP password, what will you see? And what command did you run to see the VTP
password?
Answer: You'll see the password clear as day - the password
encryption service has no effect on the VTP password. You can view the password
with the "top-secret" show vtp password command. We generally want our passwords
to be a little more secure than that!
CCNP / ONT Exam:
What's
the major difference between RED and WRED? (The answer "one letter" is not
acceptable.)
Answer: RED is a major improvement over Tail Drop, but it
still doesn't give us a great deal of control over the entire queueing and
dropping process. With one simple word, though, we do gain that control - when
we use Weighted Random Early Detection (WRED).
