• Question 211:

  You are an administrator for a large organization that uses a single registered Class B address range. Your organization contains a number of departments that range in size from 25 to 400 employees. Each department is to be given its own separate range of network addresses. Which networking strategy efficiently uses the addresses allocated to your organization?

  A. using variable length subnet masks to divide the address space
  B. obtaining some Class A address ranges for the smaller departments
  C. using /etc/netgroup to create network names for each department
  D. configuring static routing tables on all hosts and routers
  E. using switches with more ports in the larger departments
  A. using variable length subnet masks to divide the address space

• Question 212:

  A system administrator is trying to boot a system from a network boot server. The system fails to boot and displays the following error:

  Timeout waiting for ARP/RARP packet

  Which command indicates whether or not the RARP packet arrived at the server and the server replied?

  A. arp -a
  B. inetadm -d
  C. in.rarpd -da
  D. rarp -debug
  C. in.rarpd -da

• Question 213:

  You configure Solaris IP Filter on a Solaris system named myhost as a host-based firewall. While attempting to telnet to myhost from another host named remotehost, you receive this error:

  $ telnet myhost

  Trying 192.168.1.100...

  telnet: Unable to connect to remote host: Connection timed out

  You run netstat -a on myhost and find this entry:

  Local Address Remote Address Swind Send-Q Rwind Recv-Q State -------------- --------------------------- --------- ----------- ---------- ----------- ------------ myhost.23 remotehost.39846 0 0 49640 0 SYN_RCVD

  What is the cause of this problem?

  A. myhost and remotehost are on different networks.
  B. The ipf kernel module is not loaded.
  C. remotehost does not have a route to myhost.
  D. Telnet is an insecure protocol and therefore Solaris IP Filter always blocks it.
  E. myhost has a block out rule for traffic to remotehost.
  E. myhost has a block out rule for traffic to remotehost.
