Question 126

A change in your company's security policy now requires an audit trial of all administrators assuming the sysadm role, capturing:
Executed commands, including options

Logins and logouts

There are two command necessary to accomplish this change. One is a rolemod command. What is the other?

Correct Answer: B
Explanation/Reference:
Explanation:
Audit Significant Events in Addition to Login/Logout (see step 2 below) Use this procedure to audit administrative commands, attempts to invade the system, and other significant events as specified by your site security policy.
For all users and roles, add the AUE_PFEXEC audit event to their preselection mask.
# usermod -K audit_flags=lo, ps:no username
# rolemod -K audit_flags=lo, ps:no rolename
# auditconfig -setpolicy +argv
3- Record the environment in which audited commands are executed.
# auditconfig -setpolicy +arge
Note: [-t] -setpolicy [+|-]policy_flag[, policy_flag ...]
Set the kernel audit policy. A policy policy_flag is literal strings that denotes an audit policy. A prefix of + adds the policies specified to the current audit policies. A prefix of - removes the policies specified from the current audit policies. No policies can be set from a local zone unless the perzone policy is first set from the global zone.

Question 127

You are troubleshooting the Oracle Solaris11 Automated Installer (AI), which is not connecting with the IPS software repository.
Which three steps will help determine the cause of DNS name resolution failure?

Correct Answer: A,B,F
Check DNS
* (A) Check whether DNS is configured on your client by verifying that a non-empty
/etc/resolv.conf file exists.
* (F) If /etc/resolv.conf does not exist or is empty, check that your DHCP server is providing DNS server information to the client:
# /sbin/dhcpinfo DNSserv
If this command returns nothing, the DHCP server is not set up to provide DNS server information to the client. Contact your DHCP administrator to correct this problem.
* (B) If an /etc/resolv.conf file exists and is properly configured, check for the following possible problems and contact your system administrator for resolution:
** The DNS server might not be resolving your IPS repository server name.
** No default route to reach the DNS server exists.

Question 128

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

Correct Answer: A,C
Explanation/Reference:
Explanation:
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.
