• Question 243:

  The network in your company is divided into different subnets. All Solaris 10 OS servers on your network have Solaris IP Filter firewall enabled with a default policy rule that blocks all incoming connections. One subnet, with address space 10.1.1.0/24, has a server named sys-x with the IP address 10.1.1.100/32. Due to changes in your network, the sys-x server must accept connections to its X:0 to

  X:9

  terminal ports only from the 10.1.1.0/24 subnet.

  Which line must be added in the /etc/ipf/ipf.conf firewall configuration file in order to implement these changes?

  A. pass in quick proto tcp from 10.10.1.100/32 to any
  B. pass in quick proto tcp from 10.1.1.100/32 to anyport 5999 >< 6010
  C. pass in quick proto tcp from 10.1.1.0/24 to anyport 5999 >< 6010
  D. pass in quick proto tcp from 10.1.1.0/24 to anyport 5999 6010
  E. pass in quick proto rpc from 10.1.1.0/24 to anyport 5999 6010

• Question 250:

  You wish to add a static route to the routing table on your system. You add the following line to the /etc/ defaultrouter file: net 129.159.158.0 gateway gw-157-158 metric 1

  What is the cause of this problem?

  A. The entry should have been placed in the /etc/gateways file.
  B. The entry should have contained the static keyword.
  C. The entry does not contain a netmask specification.
  D. The entry should use the IP address of the gateway, not its name.
  A. The entry should have been placed in the /etc/gateways file.
