  A. 10 3 * * * /usr/adm/messages
  B. 10 3 * * * /usr/sbin/logadm
  C. 10 3 * * * /usr/sbin/syslogrotate
  D. 10 3 * * * /usi/sbin/logrotate
  E. 10 3 * * * /usr/sbin/messages
  B. 10 3 * * * /usr/sbin/logadm

  This example shows how to display the default root crontab file.

  $ suPassword: # crontab -l #ident "@(#)root 1.19 98/07/06 SMI" /* SVr4.0 1.1.3.1 */ # # The root crontab should be used to perform accounting data collection. # # 10 3 * * * /usr/sbin/logadm 15 3 * * 0 /usr/lib/fs/nfs/nfsfind 30 3 * * * [ -x /usr/lib/gss/gsscred_clean ] andand /usr/lib/gss/gsscred_clean #10 3 * * * /usr/lib/krb5/kprop_script ___slave_kdcs___

• Question 146:

  You need to connect two nonglobal zones using a private virtual network. Identify the network resources required in the global zone to accomplish this.

  A. an etherstub and two virtual network interfaces
  B. a virtual bridge
  C. two virtual network interfaces.
  D. two etherstubs
  A. an etherstub and two virtual network interfaces

• Question 147:

  Select the packet type that identifies members of the group and sends information to all the network interfaces in that group.

  A. Unicast
  B. Multicast
  C. Broadcast
  D. Bayesian
  E. Quality of Service Priority
  B. Multicast

  ---

  IPv6 defines three address types:

  unicast

  Identifies an interface of an individual node.

  multicast

  Identifies a group of interfaces, usually on different nodes. Packets that are sent to the multicast address go to all members of the multicast group.

  anycast

  Identifies a group of interfaces, usually on different nodes. Packets that are sent to the anycast address go to the anycast group member node that is physically closest to the sender.

• Question 148:

  alice is a user account used by Alice on a Solaris 11 system.

  sadmin is a role account on the same system.

  Your task is to add the command /usr/sbin/cryptoadm to the Network management profile, so that Alice can execute it, while assuming the sadmin role.

  Select the three activities necessary to accomplish this.

  A. To the file /etc/security/prof_attr, add the line: Network Management: solaris:cmd:RO::/usr/sbin/cryptoadm:euid=0
  B. To the file /etc/security/auth_attr, add the line:Network Management: solaris:cmd:RO::/usr/sbin/cryptoadm:euid=0
  C. To the file /etc/security/exec_attr.d/local-entriies, add the line:Network Management: solaris:cmd:RO::/usr/sbin/cryptoadm:euid=0
  D. Run the roles alice to ensure that alice may assume the role sadmin.
  E. Run the command profiles sadmin to ensure that the role sadmin includes the network Management profile.
  F. Run the command profiles alice to ensure that the Alice has permissions to access the Network management profile.
  G. Run the command profiles "Network management" to ensure that the Network management profile includes the sadmin role.
  C. To the file /etc/security/exec_attr.d/local-entriies, add the line:Network Management: solaris:cmd:RO::/usr/sbin/cryptoadm:euid=0
  D. Run the roles alice to ensure that alice may assume the role sadmin.
  G. Run the command profiles "Network management" to ensure that the Network management profile includes the sadmin role.

  C: /etc/security/exec_attr is a local database that specifies the execution attributes associated with profiles. The exec_attr file can be used with other sources for execution profiles, including the exec_attr NIS map and NIS+ table.

  A profile is a logical grouping of authorizations and commands that is interpreted by a profile shell to form a secure execution environment.

• Question 149:

  Your system is assigned an IP address object 192.168.0.222/24. However, the net mask -- expressed as four octets -- is required. Which is the correct netmask?

  A. 255.0.0.0
  B. 255.255.0.0
  C. 255.255.255.0
  D. 255.255.255.24
  E. 255.255.255.255
  C. 255.255.255.0

  ---

  A 24-bit network mask is expressed as 255.255.255.0.

• Question 150:

  You are configuring NFS on a server. Select the two statements that are true.

  A. Resources listed in /etc/dfs/dfstab are automatically shared on boot up.
  B. A directory cannot be shared if a subdirectory below it is already shared.
  C. Renaming a share created with the zfs set share command is not supported.
  D. NFS and SMB protocols cannot be used simultaneously to share the same directory.
  A. Resources listed in /etc/dfs/dfstab are automatically shared on boot up.
  C. Renaming a share created with the zfs set share command is not supported.

  ---

  A: ZFS can automatically share file systems by setting the sharenfs property. Using this property, you do not have to modify the /etc/dfs/dfstab file when a new file system is shared. The sharenfs property is a comma-separated list of options to pass to the share command. The value on is an alias for the default share options, which provides read/write permissions to anyone. The value off indicates that the file system is not managed by ZFS and can be shared through traditional means, such as the /etc/dfs/dfstab file. All file systems whose sharenfs property is not off are shared during boot.
