Question 1

You created a new zpool. Now you need to migrate the existing ZFS file system from pool1/prod to
pool2/prod.
You have these requirements:
1. Users must have access to the data during the migration, so you cannot shutdown the file system
while the migration takes place.
2. Because you want to copy the data as quickly as possible, you need to increase the server
resources devoted to the ZFS migration.
Which method would you use to modify the ZFS shadow migration daemon defaults to increase the
concurrency and overall speed of migration?

Accepted Answer

A

Explanation: shadowd is a daemon that provides background worker threads to migrate data for a shadow migration. A shadow migration gradually moves data from a source file system into a new “shadow” file system. Users can access and change their data within the shadow file system while migration is occurring. The shadowd service is managed by the service management facility, smf(5). Administrative actions on this service, such as enabling, disabling, or requesting restart, can be performed using svcadm(1M). The service's status can be queried using the svcs(1) command. The svccfg(1M) command can be used to manage the following parameter related to shadowd: config_params/shadow_threads Note: Oracle Solaris 11: In this release, you can migrate data from an old file system to a new file system while simultaneously allowing access and modification of the new file system during the migration process. Setting the shadow property on a new ZFS file system triggers the migration of the older data. The shadow property can be set to migrate data from the local system or a remote system with either of the following values: file:///path nfs://host:path

The storage pool configuration on your server is:
1Z0-821 practice exam questions

You back up the /pool1/data file system, creating a snapshot and copying that snapshot to tape
(/dev/rmt/0). You perform a full backup on Sunday night and Incremental backups on Monday
through Saturday night at 11:00 pm. Each incremental backup will copy only the data that has been
modified since the Sunday backup was started.
On Thursday, at 10:00 am, you had a disk failure. You replaced the disk drive (c4t0d0). You created
pool (pool1) on that disk.
Which option would you select to restore the data in the /pool1/data file system?

Accepted Answer

D

Explanation: First the full backup must be restored. This would be the Sunday backup. Then the last incremental backup must be restored. This would be the Wednesday backup. Before restoring the Wednesday incremental file system snapshot, the most recent snapshot must first be rolled back. By exclusion D) would be best answer even though it is incomplete.

Question 4

View the Exhibit and review the disk configuration. https://kxbjsyuhceggsyvxdkof.supabase.co/storage/v1/object/public/file-images/1Z0-821/page_42_img_1.jpg The following command is executed on the disk: zpool create pool1 c3t3d0s0 What is the result of executing this command?

Accepted Answer

B

Question 5

On which is the open boot prom available?

Accepted Answer

C

Explanation: No OpenBoot Environment on the Intel Platform. The Intel environment has no OpenBoot PROM or NVRAM. On Intel systems, before the kernel is started, the system is controlled by the basic input/output system (BIOS), the firmware interface on a PC. Therefore, many features provided by OpenBoot are not available on Intel systems. Note: The Open Boot PROM (OBP) bootloader only exists within SPARC. Before Solaris 10 01/06, the bootloader for Solaris x86 was a Sun customized bootstrap software. After Solaris 10 01/06, it uses GRUB, a well known bootloader that's commonly used in the Linux world. With GRUB, it's much easier to make the system dual-boot Linux and Solaris. GRUB extends the capabilities of the bootloader that was not available previously such as the ability to boot from a USB DVD drive. Those who have used Linux will be quite familiar with GRUB and its options.

Question 6

The default publisher on your system is:
1Z0-821 practice exam questions

You want to update the Oracle Solaris 11 environment on your system, but you are not able to
connect this system to the Internet to access the default Oracle repository. A repository has been
created on your local network and is named http://server1.example.com.
Which command would you choose to connect your system to the local repository?

Accepted Answer

D

Explanation: Solaris 11 Express makes it pretty easy to set up a local copy of the repository. A common reason folks need access to a local repository is because their system is not connected to the Internet. Tthe pkg set-publisher command can be used to for example add a publisher or to enable or disable a publisher. Note: Example Adding a Publisher Use the -g option to specify the publisher origin URI. # pkg set-publisher -g http://pkg.example.com/release example.com Example Specifying the Preferred Publisher Use the -P option to specify a publisher as the preferred publisher. The specified publisher moves to the top of the search order. You can specify the -P option when you add a publisher or you can modify an existing publisher. # pkg set-publisher -P example.com Example Enabling or Disabling a Publisher Use the -d option to disable a publisher. The preferred publisher cannot be disabled. A disabled publisher is not used in package operations such as list and install. You can modify the properties of a disabled publishers. Use the -e option to enable a publisher. # pkg set-publisher -d example2.com

Question 7

Identify the correct description of an IPS image.

Accepted Answer

D

Explanation: An image is a location where packages can be installed. An image can be one of three types: * Full images are capable of providing a complete system. * Partial images are linked to a full image (the parent image), but do not provide a complete system on their own. * User images contain only relocatable packages.

Question 8

Server A, Server B, and Server C are connected to the same network switch and are on the sari Each
server has a single network interface, net0.
You received a tech support call that Server B has lost network connectivity. Your troubleshooting has
discovered:
Server A can ping Server C, but not Server B.
Server B can ping localhost, but not Server A or C.
Server C can ping Server A, but not Server B.
On Server F3, you enter the following command:
dladm show-phys | grep net0
Response:
net0/v4 Ethernet down 0 unknown el00gl
What is the next logical troubleshooting action?

Accepted Answer

D

Explanation: Check the physical connection.

Question 9

To help with your troubleshooting, you need to determine the version of the OBP. Which two commands will provide you with this information?

Accepted Answer

B, C

Explanation: B: banner Displays power-on banner. The PROM displays the system banner. The following example shows a SPARCstation 2 banner. The banner for your SPARC system may be different. SPARCstation 2, Type 4 Keyboard ROM Rev. 2.0, 16MB memory installed, Serial # 289 Ethernet address 8:0:20:d:e2:7b, Host ID: 55000121 C: .version Displays version and date of the boot PROM. Note: OBP-OpenBootProm is a firmware which is placed on the sun machine's prom chip. It is a os independent user interface to deal with the sun machine's hardware components. The user interface provides one or more commands to display system information.

Question 12

You wish to troubleshoot some issues that you are having on the system. You want to monitor the /var/adm/messages file in real time. Which command would you use to do this?

Accepted Answer

B

Explanation: tail is a program on Unix and Unix-like systems used to display the last few lines of a text file or piped data. By default, tail will print the last 10 lines of its input to the standard output. With command line options the number of lines printed and the printing units (lines, blocks or bytes) may be changed. The following example shows the last 20 lines of filename: tail -n 20 filename

Question 13

zone1 is a non-global zone that has been configured and installed.

1Z0-821 practice exam questions

Which task needs to be performed before you can boot zone1?

Accepted Answer

C

Explanation: If administrative changes on the system have rendered a zone unusable or inconsistent, it is possible to change the state of an installed zone to incomplete. Marking a zone incomplete is irreversible. The only action that can be taken on a zone marked incomplete is to uninstall the zone and return it to the configured state.
