A company has contracted with a network security firm to help identify the vulnerabilities of the corporate network. The firm sends a team to perform penetration tests to the company network. Why would the team use debuggers?
to detect installed tools within files and directories that provide threat actors remote access and control over a computer or network
to reverse engineer binary files when writing exploits and when analyzing malware
to obtain specially designed operating systems preloaded with tools optimized for hacking
to detect any evidence of a hack or malware in a computer or network
Consider the following output for an ACL that has been applied to a router via the access-class in command. What can a network administrator determine from the output that is shown?
Two devices connected to the router have IP addresses of 192.168.10. x .
Two devices were able to use SSH or Telnet to gain access to the router.
Traffic from one device was not allowed to come into one router port and be routed outbound a different router port.
Traffic from two devices was allowed to enter one router port and be routed outbound to a different router port.
What command would be used as part of configuring NAT or PAT to clear dynamic entries before the timeout has expired?
clear ip dhcp
clear ip nat translation
clear access-list counters
clear ip pat statistics
