Symmetrix Solutions Expert Exam for Implementation Engineers v6.0 (E20-818)

During an initial implementation of symacl, the service processor was set up with an administrative group. In addition, an access ID PIN was entered on the Symmetrix.
What is the next step?

You are examining the performance of a weekly backup. You notice that the utilization for the Symmetrix front-end director CPUs involved in the backup is very low.
What might be causing this low utilization?

A customer plans to build an SRDF/Star configuration with the workload at Site A, the synchronous target at Site B, and the asynchronous target at Site C. In which location(s) must hosts be deployed so that they can take over the production work in the event of a failure at Site A?

Servers A and C are using PowerPath encryption. There is no access control enabled and mapping is common to all servers.
Which servers can share file information?

An Oracle customer has purchased a new Symmetrix V-Max array with a large number of
Enterprise Flash Drives (EFD). However, they still need to place part of the database on traditional Fibre Channel drives.
Which database component is least likely to benefit from being placed on EFDs?

An SRDF/Star solution has been proposed. The customer is slow to accept the solution because they are concerned about the reliability of the RDF daemon.
How would you address the customer's concern?

A customer has an Oracle 10g database with TimeFinder/Mirror producing local nightly replicas. They currently have their entire database on a single LUN and they replicate the entire database during each TimeFinder establish.
The customer has asked you to re-architect their Oracle environment to minimize the amount of data that is required to be replicated nightly. After the re-architecture a full establish is performed on all database LUNs.
Which changes can be done to meet the customer's requirements and provide a crash recoverable copy of the database?

Group Name Services (GNS) is enabled in an SRDF/Star solution. What is a benefit of
GNS in a SRDF/Star environment?

A replica of a Microsoft SQL Server database needs to be created for use in an application test environment. The database replica needs to be taken simultaneously with the corresponding application file system.
Replication Manager will be used to manage the replica creation process. The replica database can be mounted on a separate test database host from the production database.
SQL Server has been installed on this host.
Which mount recovery mode should be used when mounting this replica on the test database host?

A customer is migrating their Microsoft Exchange 2007 server from a NAS back end to a new Symmetrix V-Max SE array. Perfmon was used to create a log view of an average day's activity against the database LUN of the busiest datastore in the Exchange environment. This will serve as the performance benchmark for all other database LUNs.
There are an additional four mailbox databases on this server.
How many RAID 5-protected 15k rpm spindles are required to satisfy the performance needs of the customer for each of the mailbox databases on this server?

When adding or removing devices from an Oracle 11g ASM disk group, what must be considered to ensure replicated copies will be in a restartable state?

A TimeFinder/Snap customer has been given the task of creating a copy of their Oracle
10g database for their development team to use for testing new applications. They would like this database to be an Oracle user online inconsistent image of the database.
What is the order of actions you would perform to provide this copy?

A customer has implemented TimeFinder/Exchange Integration Module (TF/EIM) to back up two Microsoft Exchange 2007 servers. A single backup server is handling the backups of both production servers. After adding a third Exchange server, the customer notices that the "eseutil" check run as part of Exbackup2007 is taking considerably longer to run on the new server than it does on the other two servers, although there is less data to back up. No other performance issues have been noted on the new Exchange server.
What is the most likely cause of the backup delays on the new server?

A customer is concerned about the performance impact of placing a busy Oracle instance in hot backup mode. They want to take TimeFinder consistent replicas every three hours.
If Oracle is not placed in hot backup mode, what is the state of the Oracle tablespaces in the replica?

A customer has a Cascaded SRDF/Star environment. Site B fails and they undertake a reconfiguration to provide remote data protection between Sites A and C.
What is used to determine the invalid tracks that must be moved from Site A to Site C?
