  D. The original client request was a DHCPDISCOVER.

• Question 82:

  A. create /etc/dhcp.hme0
  B. execute svcadm restart svc:/network/dhcp-server:default
  C. execute ndd -set /dev/hme dhcp bind
  D. modify /etc/hostname.hme0 to include the dhcp-client tag
  A. create /etc/dhcp.hme0

  A. disable directed broadcasts on hme0 and ce1
  B. enable IPv4 routing
  C. enable IPv4 forwarding
  D. apply the latest Solaris 10 OS kernel patch
  C. enable IPv4 forwarding

• Question 84:

  C. UDP
  D. TCP
  E. FTP

• Question 85:

  A. /etc/inet/hosts
  B. /etc/inet/services
  C. /etc/inetd.conf
  D. /etc/init.d/inetinit
  E. /etc/netgroup

• Question 86:

  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?

  

  A. The telnet session is passing through an IPv4 to the IPv6 tunnel.
  B. Both hosts are on the same local network.
  C. The two hosts are connected through the Internet.
  D. The telnet session is using a source port of 6ef2 (hex) and a destination port of 5148 (hex).
  B. Both hosts are on the same local network.

• Question 87:

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

• Question 88:

  Much information can be found in log records of the Solaris IP Filter firewall. When using state, the output of the ipmon -o I command is:

  15:34:33.803147 ppp0 @0:2 b 100.100.100.103,443 -> 20.20.20.10,4923 PR tcp len 20 1488 -A

  Which statement accurately describes the third field, @0:2?

  A. Two packets are logged on the interface ppp0.
  B. There are two ppp interfaces.
  C. The size of the packet is two kilobytes.
  D. Rule 2 in group 0 caused this event to happen.
  D. Rule 2 in group 0 caused this event to happen.

• Question 89:

  You have a SPARC workstation with a single hme Ethernet interface. Which file is required for the interface to be configured at boot time?

  A. /etc/nodename.hme0
  B. /etc/nodename
  C. /etc/inet/hosts
  D. /etc/hosts
  E. /etc/hostname.hme0
  E. /etc/hostname.hme0

• Question 90:

  Click the Exhibit button.

  You configure a 6to4 router, and try to communicate from system A to system B. The interfaces of the source and destination systems are shown in the exhibit. Your ping:

  systemA# ping -s fe80::203:baff:fe02:7aa5

  yields:

  ICMPv6 Address Unreachable from gateway 2002:8193:c9f::1 for icmp6 from 2002:8193:c9f::1 to fe80::203:baff:fe02:7aa5

  What is the cause of the problem?

  

  A. You did not add a default route for the IPv6 traffic.
  B. You can NOT reach the system on the local link address.
  C. You do not have a route to gateway 2002:8193:c9f::1.
  D. The system you are pinging on does not have IPv6 configured.
  B. You can NOT reach the system on the local link address.
