• Question 1:

  You are asked to recommend a network topology for a new server network. This network will service all of your Sun servers (approximately 50 machines) and several employee workstations (approximately 20 machines). Which network topology is suited for this environment?

  A. a ring topology using intelligent hubs
  B. a VLAN topology with one VLAN for servers and another for workstations
  C. a star topology with one segment for servers and another for workstations
  D. a bus topology segmented into multiple network
  B. a VLAN topology with one VLAN for servers and another for workstations

• Question 2:

  Given the following subsection of a /etc/named.conf primary DNS server configuration file:

  acl "inside" { 192.168.2.0/24; 192.168.3.0/24; };

  acl "pusher" { 192.168.2.10/32; };

  zone "one.edu" in {

  type master;

  file "forward.zone";

  allow-query { "inside"; };

  allow-transfer { 192.168.1.10/32; };

  allow-update { 127.0.0.1; "pusher"; }

  };

  Which two statements are true? (Choose two.)

  A. Only the system with IP addresses 192.168.1.10/32 can dynamically update the zone one.edu.
  B. Only systems with IP addresses 192.168.1.0/24 receive responses from the name server.
  C. The primary DNS server can NOT be dynamically updated.
  D. The secondary DNS server 192.168.1.10/32 can receive zone transfers.
  E. The system "pusher" with IP address 192.168.2.10/32 receives responses from the name server.
  D. The secondary DNS server 192.168.1.10/32 can receive zone transfers.
  E. The system "pusher" with IP address 192.168.2.10/32 receives responses from the name server.

• Question 3:

  When you investigate tunneling, you decide to use snoop to examine the way IPv6 encapsulation works.

  You ping the destination address of the tunnel and get a successful reply. In the snoop output you discover these protocols:

  -ICMPv6

  -ETHER

  -IPv6

  -IPv4

  Place the protocol types in the order of encapsulation in which they would be observed in the snoop output.

  Note: Box 1 should contain the outermost protocol in terms of encapsulation, and Box 4 should contain the innermost encapsulated protocol.

  Select and Place:

  ssh

  http

  The IP address of the server is 10.0.0.1.

  Which two lines should be added to the Solaris IP Filter configuration file to pass the required connection requests? (Choose two.)

  A. pass in from any to 10.0.0.1 port = 22
  B. pass in from any to 10.0.0.1 port = 80
  C. pass in from 10.0.0.1 to port = 80
  D. pass in from 10.0.0.1 to port = 22
  E. pass in from any to 10.0.0.1 port = 25

  Select and Place:

  

  

• Question 7:

  A host's IPv6 link-local unicast address is based on the host's Ethernet address. A 16-bit code is inserted in the 64-bit Interface ID portion of the IPv6 address to enable a 48-bit Ethernet address to become 64 bits in length. Which value represents this added 16-bit code?

  A. FFFF
  B. FFEE
  C. FFFE
  D. FE80
  E. FEC0
  C. FFFE
