EC-COUNCIL EC-Council Certified Network Defender CND Sample Questions (Q365-Q370):

NEW QUESTION # 365
Which of the following ranges of addresses can be used in the first octet of a Class C network address?

A. 128-191
B. 224-255
C. 192-223
D. 0-127

Answer: C

NEW QUESTION # 366
A network administrator at a university campus, is investigating an incident where an unauthorized host managed to inject traffic into a VLAN it wasn't assigned to. The attacker posed as a network device to establish a link with the switch and gained access to multiple VLANs through negotiation abuse on a default-configured port. Which configuration change would best prevent this type of VLAN breach?

A. Disable auto-negotiation of trunk links on access ports
B. Assign static IP addresses to end-user machines
C. Limit the number of MAC addresses allowed on the switch port
D. Enable spanning tree protocol on trunk ports

Answer: A

Explanation:
The attack described is VLAN hopping using switch spoofing, where an attacker makes a host appear as a switch and uses Dynamic Trunking Protocol negotiation to form a trunk link with the switch. When the port is left in its default auto-negotiation state, the switch may dynamically establish a trunk and allow access to multiple VLANs. Preventing this requires disabling trunk auto-negotiation and configuring the port as a fixed access port so it cannot form a trunk connection.

NEW QUESTION # 369
Adam works as a Professional Penetration Tester. A project has been assigned to him to test the vulnerabilities of the CISCO Router of Umbrella Inc. Adam finds out that HTTP Configuration Arbitrary Administrative Access Vulnerability exists in the router. By applying different password cracking tools, Adam gains access to the router. He analyzes the router config file and notices the following lines:
logging buffered errors
logging history critical
logging trap warnings
logging 10.0.1.103
By analyzing the above lines, Adam concludes that this router is logging at log level 4 to the syslog server 10.0.1.103. He decides to change the log level from 4 to 0.
Which of the following is the most likely reason of changing the log level?

A. By changing the log level, Adam can easily perform a SQL injection attack.
B. Changing the log level grants access to the router as an Administrator.
C. Changing the log level from 4 to 0 will result in the logging of only emergencies. This way the modification in the router is not sent to the syslog server.
D. Changing the log level from 4 to 0 will result in the termination of logging. This way the modification in the router is not sent to the syslog server.

Answer: C

Explanation:
The Router Log Level directive is used by the sys log server to specify the level of severity of the log. This directive is used to control the types of errors that are sent to the error log by constraining the severity level. Eight different levels are present in the Log Level directive, which are shown below in order of their descending significance: Number Level Description 0emergEmergencies - system is unusable 1alertAction must be taken immediately 2critCritical Conditions 3errorError conditions 4warnWarning conditions 5notice Normal but significant condition 6infoInformational 7debug Debug-level messages Note: When a certain level is specified, the messages from all other levels of higher significance will also be reported. For example, when Log Level crit is specified, then messages with log levels of alert and emerg will also be reported.
