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?
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.
You upgraded your server to Oracle Solaris 11 and you imported zpool (pool1) that was created in Solaris 10. You need to create an encrypted ZFS file system in pool1, but first you need to make sure that your server supports ZFS encryption.
Which four statements are true for support of ZFS encryption?
A (not H): You can use your existing storage pools as long as they are upgraded. You have the flexibility of encrypting specific file systems.
B(not E): Can I enable encryption on an existing pool?
Yes, the pool must be upgraded to pool version 30 to allow encrypted ZFS file systems and volumes.
C(not D): ZFS encryption is integrated with the ZFS command set. Like other ZFS operations, encryption operations such as key changes and rekey are performed online.
F (not G): Encryption is the process in which data is encoded for privacy and a key is needed by the data owner to access the encoded data. You can set an encryption policy when a ZFS dataset is created, but the policy cannot be changed.
You are setting up a local image packaging System (IPS) package repository on your Oracle Solaris 11 server. The information and specifications that you have are as follows:
The Oracle Solaris11 repository ISO image has been downloaded into the /repo directory (a zfs file system).
The current publisher is:
PUBLISHER TYPE STATUS URI
solaris origin online http://pkg.oracle.com/solaris/release/
You will be replacing the current publisher with:
PUBLISHER TYPE STATUS URI
solaris origin online http://solaris.example.com/
The location of the repository will be /export/IPS. This ZFS file system has already been created.
Among the steps you will perform is to set the publisher to the local repository by using the pkg set - publisher command.
Which six other steps are required to set up the local IPS package repository?
B: Set the correct permissions.
Serving a Local Repository Using SMF
First, create a ZFS file system to hold the repository.
Next, make a local copy of the IPS repository file.
Make the contents of the repository file available to thepkg.depotd(1M) server, using thelofiadmcommand to mount the ISO image.
4. (A) Copy the repository files to the ZFS file system you created. This will increase the performance of repository accesses and avoid the need to remount the .iso image each time the system restarts. (Be sure to use /mnt/repo, not /mnt/repo/, so that you copy the repo directory and not just the files and subdirectories in the repo directory.)
# rsync -aP /mnt/repo /export/repo2010_11
You can use the df command to confirm the copy:
5. Once the files are copied, unmount the image and deallocate the block device.
6. Now that your local copy is ready, use thesvccfgcommand to configure the repository server service, specifying the location of your local repository and settingreadonlytotrue:
(D)# svccfg -s application/pkg/server setprop pkg/inst_root=/export/repo2010_11/repo
(E)# svccfg -s application/pkg/server setprop pkg/readonly=true
7. Start thepkg.depotdrepository service:
(G) # svcadm refresh application/pkg/server
(I) # svcadm enable application/pkg/server

The core dump configuration in your non global zone is
A user is running a process in a non-global zone (testzone) and the process crashes. The process information is:
user1 2663 2618 0 17:46:42 pts/2 0:00 /usr/bin/bash
When the user's process crashes in testzone, a non-global zone, where will the core dump be saved?
The line
init core file pattern: /var/core/core.%f.%p
will be used for the non-global process to determine the destination of the dump file.
Note: When a process is dumping core, up to three core files can be produced: one in the per-process location, one in the system-wide global location, and, if the process was running in a local (non-global) zone, one in the global location for the zone in which that process was running.
