This output shows that the system has a default gateway set. How can the default gateway be set?

  1. set by in.routed through the RDISC protocol

  2. set manually through: route add sys-gw default

  3. set by inetd through the use of configuration text files

Click the Exhibit button.

A system on your network is named sys-01. This system has Solaris 10 OS with packet filtering enabled and configured. The Solaris IP Filter configuration, stored in the

/etc/ipf/ipf.conf file of this system was: pass in quick proto tcp from any to any port = 22 keep state block in all and allowed an ssh connection into your sys-01 system from both hme0 and hme1 interfaces. Due to a change in your network, you had to modify the packet filtering rules of the sys-01 system. The packet filtering rules now allow ssh connections into sys-01 only using the hme0 interface. The following changes are made to

/etc/ipf/ipf.conf: pass in quick on hme0 proto tcp from any to 192.168.1.1/32 port = 22 keep state block in all

Which command loads the new packet filtering rules?
