Select the option that boots the server with the fewest services running.
Correct Answer: D
The command boot -m milestone=none is useful in repairing a system that have problems booting early. Boot Troubleshooting: To step through the SMF portion of the boot process, start with: boot -m milestone=none Then step through the milestones for the different boot levels: svcadm milestone svc:/milestone/single-user:default svcadm milestone svc:/milestone/multi-user:default svcadm milestone svc:/milestone/multi-user-server:default

Your mentor suggests using the dladm rename-link command to rename the network datalinks. What are the two advantages of following this advice?
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.

Review the storage pool information: Choose the correct procedure to repair this storage pool.
Correct Answer: C
You might need to replace a disk in the root pool for the following reasons: The root pool is too small and you want to replace it with a larger disk The root pool disk is failing. In a non-redundant pool, if the disk is failing so that the system won't boot, you'll need to boot from an alternate media, such as a CD or the network, before you replace the root pool disk. In a mirrored root pool configuration, you might be able to attempt a disk replacement without having to boot from alternate media. You can replace a failed disk by using the zpool replace command. Some hardware requires that you offline and unconfigure a disk before attempting the zpool replace operation to replace a failed disk. For example: # zpool offline rpool c1t0d0s0 # cfgadm -c unconfigure c1::dsk/c1t0d0 # cfgadm -c configure c1::dsk/c1t0d0 # zpool replace rpool c1t0d0s0 # zpool online rpool c1t0d0s0 # zpool status rpool\SPARC# installboot -F zfs /usr/platform/`uname -i`/lib/fs/zfs/bootblk /dev/rdsk/c1t0d0s0 x86# installgrub /boot/grub/stage1 /boot/grub/stage2 /dev/rdsk/c1t9d0s0

1Z0-821 Exam Question 50
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?
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.
