• Question 201:

  A new system is being installed with multiple interfaces configured and IP Forwarding enabled. One interface, ge0, connects to the primary company LAN. Another interface, ge1, connects to a LAN dedicated to administration of the company's servers.

  Given: ge0 IP Address = 10.0.0.25/32 ge1 IP Address = 192.168.1.25/32 Admin network = 192.168.1.0/24 Primary network = 10.0.0.0/24

  Solaris IP Filter firewall must be configured in a way that:

  1- Systems on the admin network can reach the primary network. 2- The system itself has to be reached using ssh from all systems on the admin network. 3- Systems on the primary network cannot reach any systems on the admin network.

  Which three rules should be included in the Solaris IP Filter configuration? (Choose three.)

  A. pass out quick log from 192.168.1.0/24 to any keep state
  B. block out quick log on ge0 from 192.168.1.0/24 to any
  C. pass out quick on ge0 from 10.0.0.25 to 10.0.0.0/24 flags keep state
  D. block out all
  E. pass in quick proto tcp on ge1 from 192.168.1.0/24 to 192.168.1.25/32 port = 22 flags keep state
  F. pass in quick from 192.168.1.0/24 to 10.0.0.0/24 flags keep state
  G. block in all
  E. pass in quick proto tcp on ge1 from 192.168.1.0/24 to 192.168.1.25/32 port = 22 flags keep state
  F. pass in quick from 192.168.1.0/24 to 10.0.0.0/24 flags keep state
  G. block in all

  B. netstat hme link_mode
  C. netstat -I hme
  D. ndd -get /dev/hme link_mode
  E. ndd -get /dev/hme link_status

  D. ndd -get /dev/hme link_mode
  F. ndd -get /dev/hme link_speed

• Question 204:

  A. The router address listed in /etc/defaultrouter is used instead.

  C. The default router entry for the router is immediately removed from the host's routing table.
  D. The in.rdisc process on the host terminates.
  E. The default router entry for the router is removed from the host's routing table after a timeout of about 30 minutes.
  B. The default router entry is reestablished when the router restarts broadcasting RDISC packets.
  E. The default router entry for the router is removed from the host's routing table after a timeout of about 30 minutes.

• Question 205:

  A. ndd
  B. netstat
  C. inetinit
  D. ifconfig
  E. route
  A. ndd

• Question 206:

  A printer is connected to the same subnet as your workstation. The printer is identified as:

  A. netconfig -p 192.204.200.12 printer1
  B. arp -p printer1 8:0:20:21:38:6b
  C. arp -s printer1 8:0:20:21:38:6b pub
  D. rarp -s 192.204.200.12 8:0:20:21:38:6b

  D. The address is an invalid IP address.
  B. The address responded to a ping from the DHCP server.

• Question 208:

  Click the Exhibit button.

  While diagnosing an IPv6 problem, you run snoop and receive the output shown in the exhibit.

  What can be determined from this output?

  C. The telnet session is passing through an IPv4 to the IPv6 tunnel.
  D. The two hosts are connected through the Internet.
  A. Both hosts are on the same local network.

• Question 209:
