• Question 72:

  The default configuration of the Solaris 10 OS has packet filtering disabled on all network interfaces. To enable packet filtering on the hme0 interface of a running system, the related hme line in the /etc/ipf/pfil.ap file must be uncommented:

  # IP Filter pfil autopush setup # # See autopush(1M) manpage for more information. # # Format of the entries in this file is: # #major minor lastminor modules

  #le -1 0 pfil #qe -1 0 pfil hme -1 0 pfil #qfe -1 0 pfil #eri -1 0 pfil #ce -1 0 pfil #bge -1 0 pfil #be -1 0 pfil #vge -1 0 pfil #ge -1 0 pfil #nf -1 0 pfil #fa -1 0 pfil #ci -1 0 pfil #el -1 0 pfil #ipdptp -1 0 pfil #lane -1 0 pfil #dmfe -1 0 pfil

  Which UNIX command must be executed to enable Solaris IP Filter firewall for the hme0 interface without rebooting the system?

  A. ifconfig hme0 down; ifconfig hme0 unplumb; ifconfig hme0 plumb; autopush -f /etc/ipf/pfil.ap
  B. autopush -f /etc/ipf/pfil.ap; ifconfig hme0 modlist
  C. ifconfig hme0 pfil; ifconfig hme0 modlist
  D. ifconfig hme0 modlist; autopush -f /etc/ipf/pfil.ap
  E. autopush -f /etc/ipf/pfil.ap; ifconfig hme0 down unplumb; ifconfig hme0 plumb
  E. autopush -f /etc/ipf/pfil.ap; ifconfig hme0 down unplumb; ifconfig hme0 plumb

• Question 75:

  A new system administrator tries to determine the IPv6 IPMP configuration and sees the following:

  # grep failover /etc/hostname6* /etc/hostname6.hme0: -failover group mgrp6 /etc/hostname6.qfe0: -failover group mgrp6-1 /etc/hostname6.qfe1: -failover group mgrp6-1

  Which statement is true?

  A. The hme0 is a spare interface for the mgrp6-1 failover group.
  B. The system is configured so that notifications are generated when hme0 fails.
  C. Interface hme0 has priority over qfe0/qfe1 when doing a failover.
  D. There has definitely been an error configuring hme0.
  B. The system is configured so that notifications are generated when hme0 fails.

• Question 80:

  The network you are managing has many services. One of the servers on your network with IP address 129.157.10.10, on the interface eri0, is an HTTP server.

  The HTTP server shown in the graphic has the Solaris IP Filter firewall enabled. The rule, which allows any incoming Internet connections on the interface eri0 for the HTTP service, must be designed.

  Use three options to complete the Solaris IP Filter firewall rule.
