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 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 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 4
You have 2 NTP servers in your network – 10.1.1.1 and 10.1.1.2. You want to configure a Cisco router to use 10.1.1.2 as its NTP server before falling back to 10.1.1.1. Which commands will you use to configure the router?
A. ntp server 10.1.1.1ntp server 10.1.1.2
B. ntp server 10.1.1.1ntp server 10.1.1.2 primary
C. ntp server 10.1.1.1ntp server 10.1.1.2 prefer
D. ntp server 10.1.1.1 fallbackntp server 10.1.1.2

Correct Answer: C Explanation Explanation/Reference:
Explanation:
Preferred server A router can be configured to prefer an NTP source over another. A preferred server’s responses are discarded only if they vary dramatically from the other time sources. Otherwise, the preferred server is used for synchronization without consideration of the other time sources. Preferred servers are usually specified when they are known to be extremely accurate. To specify a preferred server, use the prefer keyword appended to the ntp server command. The following example tells the router to prefer TimeServerOne over TimeServerTwo: Router#config terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)#ntp server TimeServerOne prefer Router(config)#ntp server TimeServerTwo Router(config)#^Z
QUESTION 5
The following command is issued on a Cisco Router:
Router(configuration)#logging console warnings
Which alerts will be seen on the console?
A. Warnings only
B. debugging, informational, notifications, warnings
C. warnings, errors, critical, alerts, emergencies
D. notifications, warnings, errors
E. warnings, errors, critical, alerts

Correct Answer: C Explanation
Explanation/Reference:
Explanation:
Cisco routers 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, when you enable console logging of warning messages (level 4), it will log levels 0-4, making the correct answer warnings, errors, critical, alerts, and emergencies.

QUESTION 7
You enabled CDP on two Cisco Routers which are connected to each other. The Line and Protocol status for the interfaces on both routers show as UP but the routers do not see each other a CDP neighbors. Which layer of the OSI model does the problem most likely exist?
A. Physical
B. Session
C. Application
D. Data-Link
E. Network

Correct Answer: D Explanation
Explanation/Reference:
Explanation:

CDP is a protocol that runs over Layer 2 (the data link layer) on all Cisco routers, bridges, access servers,
and switches. CDP allows network management applications to discover Cisco
devices that are neighbors of already known devices, in particular, neighbors running lower-layer,
transparent protocols. With CDP, network management applications can learn the device
type and the SNMP agent address of neighboring devices. This feature enables applications to send
SNMP queries to neighboring devices. In this case, the line protocol is up which means
that the physical layer is operational (layer 1) but the data link layer is not.

At which layer of the OSI model does the Spanning Tree Protocol (STP) operate at?
A. Layer 5
B. Layer 4
C. Layer 3
D. Layer 2
E. Layer 1

Correct Answer: D Explanation
Explanation/Reference:
Explanation:
Spanning-Tree Protocol (STP) is a Layer 2 (L2) protocol designed to run on bridges and switches. The specification for STP is called 802.1d. The main purpose of STP is to ensure that you do not run into a loop situation when you have redundant paths in your network. Loops are deadly to a network.
QUESTION 19
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.

Correct Answer: CD Explanation
Explanation/Reference:
Explanation:
The point of this question is the form of multicast MAC address, and the conversion between the multicast
MAC address and IP address.

The multicast MAC address is 6 bytes(48 bits), the first 3 bytes (24 bits) of the multicast MAC address are
0x01-00-5E, the last 3 bytes(24 bits) of the multicast MAC address =0 + 23 bit(the last 23 bit of the IP

address). “0x01-00-5E” is a reserved value that indicates a multicast application.
