F. zpool destroy pool1 zpool destroy pool2 zpool create pool1 mirror c3t2d0 c3t3d0 c3t4d0 c3t5d0

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. 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.

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

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

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

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

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

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

H. 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.

You are troubleshooting the failure of a computer to mount an NFS file system hosted by a server (hostname mars) in the local area network.

The core dump configuration for your system is:

A user is running a process in the global zone and the process crashes. The process information is:

User1 2663 2618 0 17:46:42 pts/2 0:00 /usr/bin/bash

The server host name is: zeus

What will the per-process core file be named?

A. core.bash.2663.global

B. core.bash.2663.zeus

C. /var/core/core.bash.2663

D. /var/core/core.bash.2663.global

A. If a location is explicitly enabled, it remains active until explicitly changed.

B. Wireless security keys can be configured by using the nwammgr command.

C. NWAM stores profile information in /etc/ipadm/ipadm.conf and /etc/dladm/datalink.conf.

D. Multiple locations may be automatically activated in systems with multiple network interface cards.

E. Interface NCU Properties "float" and are automatically attached to the highest priority Link NCU Property.

F. If the DefaultFixed NCP is enabled, persistent configuration, stored in /etc/ipadm.conf and /etc/dladm/ datalink.conf is used.

Review the zonestat command

zonestat -q -r physical-memory -R high -z dbzone -p -p "zones" 10 24h 60m

Select the option that correctly describes the information that is displayed by this command

A. It is a sample of dbzone's physical memory usage taken every hour over a 24-hour period Only the top 10 samplings of peak memory usage are displayed. All other utilization data is eliminated

B. It is a sample of dbzone's CPU, virtual memory, and networking utilization Physical memory is excluded from the report The sampling is taken every 10 minutes over a 24 hour period and peak utilization is displayed each hour.

C. ft is a sample of dbzone's CPU, virtual memory, and networking utilization Physical memory is excluded from the report. The sampling is taken every 10 seconds over a 24- hour period and displayed each hour.

D. It is a sample of dbzone's memory and CPU utilization every 10 seconds over a 24-hour period Only peak virtual memory usage and CPU utilization are displayed each hour All other utilization data is eliminated.

E. it is a sample of dbzone's physical memory usage taken every 10 seconds over a 24- hour period. Only peak memory usage is displayed each hour All other utilization data is eliminated.
