When using TEIM which volume layout is required?
A.Configure the data files and logs on the same volume
B.Separate storage groups must always reside on separate volumes
C.Data stores must be stored on the same Symmetrix logical volume
D.The checkpoint file for a storage group and the databases that make up that storage group must be located on different volumes
Answer: B

2. A customer is using a RAID-1 standard device that already has a paired BCV and one CopyOnAccess Clone copy.
What is the maximum number of additional CopyOnWrite Snap sessions that the customer can create on this device?
A.1
B.7
C.13
D.16
Answer: C

3. You are reconfiguring a DMX with Solutions Enabler SYMCLI. There are several volumes that are already mapped but not in use. The customer wants to convert them to metavolumes.
What do you do to perform this task?
A.Unmap the devices, set the volumes to not ready, create the metavolumes, and map them
B.Create a device group, unmap the devices, create the metavolumes, and map the metavolumes
C.Set the volumes to not ready, unmap the devices, create the metavolumes, and mount the volumes
D.Create a device group, set volumes to not ready, unmap the devices, create metavolumes, and map the metavolumes
Answer: D

4. You are implementing SRDF at a customer site, and the customer asks you to configure three additional R1 devices on the source Symmetrix and corresponding R2 devices on the target Symmetrix. You have a host attached to the Symmetrix with SYMCLI already installed, and you have created a device file.
Which operation(s) will create the SRDF device pairs and establish them?
A.symrdf createpair command with -establish
B.symrdf createpair command followed by symmir establish command
C.symmir createpair command followed by symmir establish command
D.symcfg createpair command followed by symdev establish command
Answer: A

5. Your DMX configuration is approaching 16,000 volumes. In defining the Volume Access Control Database (VCMDB), your 96-cylinder volume is configured as a type-5 VCM database. Once implemented, an old host cannot access the new VCM for device masking commands through SYMCLI. You have verified that the zoning information is correct and can see the VCM using syminq.
What is the next step for troubleshooting?
A.Verify that the old host is at the latest recommended version of Solutions Enabler using symcli
B.Initialize the VCMDB using:
symmaskdb sid nnn init file MyInitBackup vcmdb_type 5
C.Initialize the VCMDB to a type-4 using:
symmaskdb sid nnn init file MyInitBackup vcmdb_type 4
D.Backup and restore the VCMDB using:
Answer: A

6. A customer wants to split a BCV copy of the production database once a week and then use Clones of the BCV for testing.
Which operations are required to make a Clone usable by a host?
A.Activate the Clone and split the Clone
B.Establish the Clone and split the Clone
C.Split the BCV, create the Clone, and activate the Clone
D.Establish the BCV, create the Clone, and mount the Clone
Answer: C

7. A customer has an application that runs on a SQL Server 2000 database, and the information is stored on a DMX. The customer wants to make daily, local backups of the database using TSIM.
What action does the tsimsnap backup command perform to create this local copy?
A.Establishes standard and BCV volumes
B.Keeps track of the database backup history
C.Requests the operator perform a SQL Server snapshot
D.Flushes the filesystems used by the database and performs the BCV split
Answer: D

8. After doing a BCV split and mount on a Window's backup host, the customer determines the data on the BCV copy is inconsistent and missing files. The customer's script is using the SUI utility symntctl.
Which command should be used to help prevent the inconsistent BCV?
A.umask
B.flush
C.umount
D.deport
Answer: B

Which tool is used to align the disk partition?
A.fdisk
B.format
C.Diskpar
D.Diskpart
Answer: A

10. A customer is implementing SRDF/A over GigE but is having problems getting through the corporate firewall.

A.Less bandwidth means more cache required
B.Less bandwidth means longer SRDF/AR cycles
C.More bandwidth means longer SRDF/AR cycles
D.More bandwidth means potential data inconsistency in case of failure
Answer: B
