• Question 99:

  Place the text in its proper place to create a Solaris IP Filter rule that blocks, returns RST, and logs only incoming auth connections on tcp port 113.

  Select and Place:

  

  

• Question 100:

  Your network is made of many servers running many services. One of these systems is named system- ssh, which is an ssh server. The ssh server is on Solaris 10 OS with the packet filter enabled and configured. The rule set is:

  pass in quick proto tcp from any to any port = 22 keep state block in all

  Due to maintenance on the ssh software, a telnet connection must be used instead. You change the rule set in:

  pass in quick proto tcp from any to any port = 23 keep state block in all

  These are added as an inactive rule set to the ipf kernel module of Solaris 10 OS.

  Which command do you execute to list the inactive rule set and make it active?

  A. ipfstat -iI; ipf -s
  B. ipmon -i; ipf -I
  C. ipmon -l; ipfstat -i
  D. ipmon -i; ipf -s
  E. ipfstat -i; ipf -I
  A. ipfstat -iI; ipf -s
