Oracle ZFS Storage ZS3 Implementation Essentials

Question No: 21

The storage administrator wants to configure a snapshot in the ZFS storage ZS3. Which option must the administrator use to ensure application consistency?

  1. Schedule snapshots to occur at a specific time each day.

  2. Quiesce, sync, or shut down the application and then take a snapshot of the master LUN.

  3. Quiesce, sync, or shut down the application prior to taking a snapshot of the project defined for the application.

  4. Schedule project snapshots to occur periodically. This way the storage administrator will be sure to get all open files by the end of the day.

Answer: B

Question No: 22

Which option is true when allocating and verifying storage?

  1. For expandable systems, JBODs can be allocated as quot;quarter/1 quot;half/1 or quot;whole.quot;

  2. In general, half JBODs are the preferred unit for managing storage, but quarter JBODs can be used where storage needs are small.

  3. The allocation of hot spares depends on the storage profile chosen (for example, striped).

  4. All devices must be connected and functioning before continuing past the verification step.

Answer: B Explanation:

Verification and Allocation

The verificationphase allows you to verify that all storage is attached and functioning, and

allocatesdisks within chassis. In a standalone system, this presents a list of all available storage and drive types, with the ability to change the number of disks to allocate to the new pool. By default, the maximum number of disks are allocated, but this number can be reduced in anticipation of creating multiple pools.

In an expandable system, JBODs are displayed in a list along with the head node, and allocation can be controlled within each JBOD. For each JBOD, the system must import available disks, aprocess that can take a significant amount of time depending the number and configuration of JBODs. Disks within the system chassis can be allocated individually (as with cache devices), but JBODs must be allocated as either #39;whole#39; or #39;half#39;. In general, whole JBODs are the preferred unit for managing storage, but half JBODs can be used where storage needs are small, or where NSPF is needed in a smaller configuration.

  2. Delete Users.

  3. Delete Storage Pool.

  4. Create new LUNs.

  5. Create Storage Pool.

Answer: D,E

Question No: 24

The storage administrator is beginning the initial setup phase. Identify the information required.

  1. IP address, netmask, Share name, production username, and password

  2. IP address, netmask, DNS address, Share name, and snapshot schedule

  3. DHCP server name, Active Domain name, Share name, CIFS server name, username, and password

  4. DNS server, gateway or router IP, IP address, netmask, and root password

  5. AD name, DNS name, Timeserver (NTP) name/address, Share name, and root password

Answer: D Explanation:

A new Oracle ZFS Storage Appliance does not contain any network configuration. The initialinstallation process will walk you through a procedure to provide the Oracle ZFS Storage Appliancewith an IP address, gateway and DNS information to set up a single network port for gainingadministrative access to the system. A connection to the Oracle ZFS Storage Appliance ILOM serverneeds to be set up in order to complete this initial Oracle ZFS Storage Appliance installation process.

  1. Administrators trying to administer the domain

  2. Users who are using the Find feature of the Start menu to find remote shares based on identifier or description

  3. Users trying to find shares in large Active Directory environments

  4. Users trying to add a meaningful description to shares so that others may find it

Answer: B,C

Explanation: Publishing Shares to Active Directory Publishing shares makes it easier for a resource to be found in large AD environments. By publishing shares to Active Directory, users can use the Find feature on the Start menu on their Windows desktops to find remote shares based on their identifier or description. In order to publish shares to Active Directory, open the File Server Management console, click on Shares, right click on the share name to be published, click on properties, then choose the Publish tab and check the “Publish this share in Active Directory”
