Question 71

After installing the OS, you boot the system and notice that the syslogd daemon is not accepting messages from remote systems.
Which two options should you select to modify the syslogd daemon configuration so that it accepts messages from remote systems?

Correct Answer: B,D
B: The /etc/default/syslogd file contains the following default parameter settings. See FILES.
LOG_FROM_REMOTE
Specifies whether remote messages are logged. LOG_FROM_REMOTE=NO is equivalent to the -t command- line option. The default value for LOG_FROM_REMOTE is YES.

Question 72

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 73

User1 is attempting to run the following command: cp bigfile verybig
The system displays the following errer:
cp: cannot create verybig: Disc quota exceeded
Your initial troubleshooting shows that the df -h command indicates the account is at 100% capacity. What command would you use to determine how much disk space the user has available?

Correct Answer: A
ZFS quotas can be set and displayed by using the zfs set and zfs get commands. In the following example, a quota of 10 Gbytes is set on tank/home/bonwick.
# zfs set quota=10G tank/home/bonwick # zfs get quota tank/home/bonwick NAME PROPERTY VALUE SOURCE tank/home/bonwick quota 10.0G local

Question 74

Your server has a ZFS storage pool that is configured as follows:

The server has two spate 140-GB disk drives: c3t5d0 c3t6d0
Which command would add redundancy to the pool1 storage pool?

Correct Answer: A
Explanation/Reference:
Explanation:
You can convert a non-redundant storage pool into a redundant storage pool by using the zpool attach command.
Note: zpool attach [-f] pool device new_device
Attaches new_device to an existing zpool device. The existing device cannot be part of a raidz configuration. If device is not currently part of a mirrored configuration, device automatically transforms into a two-way mirror of device and new_device. If device is part of a two-way mirror, attaching new_device creates a three-way mirror, and so on. In either case, new_device begins to resilver immediately.
