Show Answer Hide Answer
Correct Answer: A

Question No. 2

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?

Show Answer Hide Answer
Correct Answer: A, B, C, F

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.


Question No. 3

You execute the command:

usermod -K limitpnv=all,\!file_wnte guest

What is the result of this command?

Show Answer Hide Answer
Correct Answer: C

Question No. 4

Your mentor suggests using the dladm rename-link command to rename the network datalinks.

What are the two advantages of following this advice?

Show Answer Hide Answer
Correct Answer: A, E

A: To rename the bge0 link to mgmt0, enter the following command:

# dladm rename-link bge0 mgmt0

E: Consider that the bge0 device, whose link was named mgmt0 as shown in the previous example, needs to be replaced with a ce0 device because of a hardware failure. The bge0 NIC is physically removed, and replaced with a new ce0 NIC. To associate the newly added ce0 device with the mgmt0 configuration previously associated with bge0, enter the following command:

# dladm rename-link ce0 mgmt0

Note: How to Rename a Datalink

Use this procedure if you want to change a datalink name to a customized name. For example, some of the datalinks in upgraded system might have retained legacy hardware-based names and you want to change these names to generic ones.

Note: dladm rename-link [-R root-dir] link new-link

Rename link to new-link. This is used to give a link a meaningful name, or to associate existing link configuration such as link properties of a removed device with a new device.


Question No. 5

Select two statements that correctly describe the capabilities of the Distribution Constructor.

Show Answer Hide Answer
Correct Answer: A, D

A: You can use the distribution constructor to create the following types of Oracle Solaris images:

* (A) x86 or SPARC ISO Image for Automated Installations

* Oracle Solaris x86 live CD image

* x86 or SPARC Oracle Solaris text installer image

* x86 Oracle Solaris Virtual Machine

Note: You can use the distribution constructor to build custom Oracle Solaris images. Then, you can use the images to install the Oracle Solaris software on individual systems or multiple systems. You can, also, use the distribution constructor to create Virtual Machine (VM) images that run the Oracle Solaris operating system.

D: Checkpointing Options

You can use the options provided in the distro_const command to stop and restart the build process at various stages in the image-generation process, in order to check and debug the image that is being built. This process of stopping and restarting during the build process is called checkpointing.

Incorrect answers:

B: Optionally, a USB image can be created, based on a generated x86 ISO image.
