NEW QUESTION 39
You want to deploy Oracle Solaris 11 with the Automated Installer (AI). You need to make sure that your server and network meet the requirements for using AI.
Choose the three options that describe the requirements for using AI.

You can create only one manifest per install service. If you need more than one manifest create multiple install services.

If two client machines have different architectures and need to be installed with the same version of the Oracle Solaris 11 OS, then create two AI manifests and a single install service.

You need a separate install service for each different client architecture that you plan to install, and for each different version of the Oracle Solaris 11 OS that you plan to install on client systems.

If two client machines have different architectures and need to be installed with different versions of the Oracle Solaris 11 OS, then create two AI manifests and two install services.

The install server needs to be able to access an Oracle Solaris Image Packaging System (IPS) software package repository; the clients do not.

The install server can be either an x86 machine or a SPARC machine.

NEW QUESTION 40
Which two are true about accounts, groups, and roles in the Solaris user database?

All Solaris user accounts must have a unique UID number.

A Solaris account name may be any alphanumeric string, and can have a maximum length of 8 characters.

Account UID numbers 0-09 are system-reserved.

The GID for an account determines the default group ownership of new files created by that account.

The groups that an account is a member of are determined by the entries in the /etc/group file.

NEW QUESTION 41
The advantage of core tiles is that they allow you an opportunity to examine the cause of problems, so that they can be resolved.
However, core files must be managed because they_____.

take up large amounts of disk space

make numerous entries into the /var/adm/wtmpx file

steal resources from the processor, slowing down system performance

fill up swap space; this will begin to slow the system due to swaps

fill up swap space; this will begin to slow the system due to paging

NEW QUESTION 42
New features wore added to ZFS in Oracle Solaris11. Your justification to upgrade from Solaris10 to oracle Solaris11 is that it will be possible to take advantage of the enhancements that were made to ZFS.
Identify the three ZFS functions and features that are included in Oracle Solaris 11, but not in Solaris 10.

Encrypted ZFS datasets

Ability for ZFS to detect and remove redundant data from the tile system

Next you execute:
# zfs destroy tank/database
Which statement is true about the result of executing this command?

It destroys the tank/database dataset.

It destroys tank/database and all descendant datasets.

It fails because the tank/[email protected] snapshot depends on the tank/database dataset.

It fails because the tank/[email protected] clone depends on the tank/database dataset.

It fails because the tank/database data set is not empty.

NEW QUESTION 46
You are setting up an automated installer (AI) install server and issue the following command:
installadm create-service -n prod_ai -s /repo/prod_ai.iso
-i 192.168.1.100 -c 5 -d /export/repo
Which four options describe the install server that you have configured?

The service name is prod_ai.

DHCP base IP address is 192.168.1.100

The initial IP address for the install clients will be 192.168.1.100. This IP address is temporary. After the client is booted, it will use IP addresses in the following range: 192.168.1.101-105.

Five IP addresses are allocated for DHCP clients, starting with 192.168.1.100.

The Install server will support up to five clients.

The AI net image ISO file is located in /repo/prod and the net image ISO will be unpacked in /export/ repo.

The AI net image ISO file is located in /repo/repo and is named /repo/prod/_ai.iso.

NEW QUESTION 47
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?

The encrypted file system must have been created in Oracle Solaris11. To encrypt a ZFS file system from a previous version of Solaris, upgrade the zpool and create a new encrypted ZFS file system into the encrypted ZFS file system.

If you plan to create an encrypted file system in an existing zpool, the zpool must be upgraded to ZFS version 30.

ZFS encryption is integrated with the ZFS command set and no additional packages need to be installed.

ZFS encryption requires that the ZFS Dataset Encryption package be installed.

If you plan to create an encrypted file system in an existing zpool, the pool must be upgraded to ZFS version 21, minimum.

Encryption is supported at the pool or dataset (file system) level.

Encryption is supported at the pool level only for every file system in the pool will be encrypted.

You cannot create an encrypted file system in a zpool that was created prior to oracle Solaris11. Create a new zpool in Solaris11, create an encrypted ZFS file system in the new zpool, and move or copy the data from the existing file system into the new encrypted file system.

NEW QUESTION 48
