Exam A
QUESTION 1
The following commands are issued on a Cisco Router:
Router(configuration)#access-list 199 permit tcp host 10.1.1.1 host 172.16.1.1
Router(configuration)#access-list 199 permit tcp host 172.16.1.1 host 10.1.1.1
Router(configuration)#exit
Router#debug ip packet 199
What will the debug output on the console show?
A. All IP packets passing through the router
B. Only IP packets with the source address of 10.1.1.1
C. All IP packets from 10.1.1.1 to 172.16.1.1
D. All IP Packets between 10.1.1.1 and 172.16.1.1
Correct Answer: D Section: (none) Explanation
Explanation/Reference:
Explanation:
In this example, the “debug ip packet” command is tied to access list 199, specifying which IP packets
should be debugged. Access list 199 contains two lines, one going from the host with IP address 10.1.1.1
to 172.16.1.1 and the other specifying all TCP packets from host 172.16.1.1 to 10.1.1.1.
QUESTION 2
What level of logging is enabled on a Router where the following logs are seen?
%LINK-3-UPDOWN: Interface FastEthernet0/1, changed state to up
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/1, changed state to up
A. alerts
B. critical
C. errors
D. notifications
Correct Answer: D Section: (none) Explanation
Explanation/Reference:
Explanation:
Cisco routers, switches, PIX and ASA firewalls prioritize log messages into 8 levels (0-7), as shown below: LevelLevel NameDescription 0 Emergencies System is unusable 1 Alerts Immediate action needed 2 Critical Critical conditions 3 Errors Error conditions 4 Warnings Warning conditions 5 Notifications Informational messages 6 Informational Normal but significant conditions 7 Debugging Debugging messages
When you enable logging for a specific level, all logs of that severity and greater (numerically less) will be logged. In this case we can see that logging level of 3 (as seen by the 3 in “LINK-3- UPDOWN”) and level 5 (as seen by the 5 in “LINEPROTO-5-UPDOWN”) are shown, which means that logging level 5 must have been configured. As shown by the table, logging level 5 is Notifications.

QUESTION 3
In computer networking a multicast address is an identifier for a group of hosts that have joined a multicast group. Multicast addressing can be used in the Link Layer (OSI Layer 2), such as Ethernet Multicast, as well as at the Internet Layer (OSI Layer 3) as IPv4 or IPv6 Multicast. Which two descriptions are correct regarding multicast addressing?
A. The first 23 bits of the multicast MAC address are 0x01-00-5E. This is a reserved value that indicates a multicast application.
B. The last 3 bytes (24 bits) of the multicast MAC address are 0x01-00-5E. This is a reserved value that indicates a multicast application.
C. To calculate the Layer 2 multicast address, the host maps the last 23 bits of the IP address into the last 24 bits of the MAC address. The high-order bit is set to 0.
D. The first 3 bytes (24 bits) of the multicast MAC address are 0x01-00-5E. This is a reserved value that indicates a multicast application.
