Welcome back! It's August 1, 2008, and here are the answers to yesterday's Cisco practice exam questions!
Be sure to visit again later today for another set of questions here on the blog, the answers to my latest CCNA Security certification exam over on the main site, a new CCNA / CCENT practice exam, and some CCNP BSCI questions as well!
CCNA Certification:
You've configured OSPF on four routers on a broadcast segment. You notice that a DR and BDR have been elected, but some adjacencies are stopping at the 2-way state. What should you do?
A. Nothing - that's what you're supposed to see.
B. Use the ip ospf priority 0 command on the appropriate interfaces on the DROTHER routers.
C. Use the ip ospf priority 0 command on the appropriate interfaces on the DR and BDR.
D. Use the neighbor command on the DR and BDR to complete the incomplete adjacencies.
Answer: A. This is a default behavior of OSPF that helps to cut down on the number of LSAs being transmitted on a broadcast segment.
The only routers that will have an adjacency to all other routers on the segment are the DR and BDR. The DROthers will only have full adjacencies with the DR and BDR, never with other DROthers.
CCENT Certification:
How many wires "roll over" in a rollover cable?
A. 2
B. 3
C. 4
D. 6
E. 8
Answer: E. All eight wires in a rollover cable will "roll over" to another pin at the remote end, with the wire on Pin 1 at one end rolling over to Pin 8 at the other end, the wire on Pin 2 at one end rolling over to Pin 7 at the remote end, and so forth.
CCNA Security Certification / CCNP ISCW Exam:
There are three basic methods IPS uses to identify potentially malicious traffic. Name all three and give a brief definition of each.
Both the IPS and IDS can base their identification of dangerous and malicious traffic on the following:
Policy, where a configured policy may ban particular IP addresses, ports, or even websites
Signature, where byte patterns are considered along with other values.
Anomaly, where differences from normal traffic patterns are sought and detected.
CCNP Certification / BSCI Exam:
You've run the show ip bgp command and note a value under "LocPrf". If that value is the default, what is it? And what is this particular value used for?
Answer: That's the Local Preference. LOCAL_PREF is a well-known BGP attribute that is used when multiple paths between autonomous systems exist. The LOCAL_PREF attribute is just that… local. Routers within the local AS are told what path to use to exit that AS. The local preference value is passed only among iBGP peers, and this value never leaves the local AS.
The default Local Preference is 100.
CCNP Certification / BCMSN Exam:
What command resulted in the following output?
SW1# ?
Port Security : Enabled
Port Status : Secure-up
Violation Mode : Shutdown
Aging Time : 0 mins
Aging Type : Absolute
SecureStatic Address Aging : Disabled
Maximum MAC Addresses : 3
Total MAC Addresses : 2
Configured MAC Addresses : 2
Sticky MAC Addresses : 0
Last Source Address:Vlan : 0000.0000.0000:0
Security Violation Count : 0
Answer:
SW1#show port-security interface fast 0/2
You didn't need to identify the port number to answer the question correctly, but you do have to specify it when you use this command.
CCNP / ONT Exam:
What's the difference between an ad hoc wireless network and an infrastructure wireless network?
Answer: In an ad hoc WLAN ("wireless LAN"), the wireless devices communicate with no WAP involved. A more common wireless configuration is an infrastructure WLAN, where a WAP is used to allow multiple devices to connect to the wired network
