Here are the answers to the Cisco certification exam practice questions posted Wednesday, May 21!
CCNA And CCENT Exam:
A frame enters a switchport. Which of the following does the switch examine first?
A. Source IP address
B. Destination IP address
C. Source MAC address
D. Destination MAC address
Answer: C. The switch will check the source MAC address first, and then decide whether that particular address and corresponding port number need to be added to the switch's MAC address table.
CCNP Certification / BSCI Exam:
In the following EIGRP configuration, the number 100 appears twice. Describe the purpose of each.
R2(config)#router eigrp 100
R2(config-router)#redistribute ospf 1 metric 1544 100 1 255 1500
Answer: The first "100" is the EIGRP AS number. The second "100" is the delay metric for the OSPF routes redistributed into EIGRP.
CCNP Certification / BCMSN Exam:
What single command can be used to change the speed and/or duplex setting of multiple ports simultaneously?
Answer: interface range.
CCNP Certification / ISCW Exam:
Name and briefly describe three different kinds of recon attacks.
A reconnaissance attack isn't necessarily destructive in itself. Quite the contrary, the attacker really doesn't want to draw your attention to this type of attack. A reconnaissance attack is primarily designed to gather information and test network defenses in preparation for a future - and very destructive - network attack.
Just as a successful ping to a single IP address will tell you if that host is online or not, a ping sweep sends pings to a range of addresses to find out which ones are in use. In a similar fashion, port scans are used to find out what ports are open and can possibly be compromised. Packet sniffers can be used for much the same reason.
And just as asking questions about someone can yield information about that person, queries can help a network attacker gain information about your network. DNS queries, SQL queries, and Internet Information queries are just three query types that can be used to gather information for future attacks.
CCNP Certification / ONT Exam:
You want to run Weighted Fair Queueing on a link that's running faster than 2.048 MBPS. What global configuration command allows this?
Answer: None - WFQ does not work on interfaces running at a speed higher than 2.048 MBPS.
