A database administrator is concerned about the performance impact of placing a busy Oracle instance in hot backup mode. They want to take TimeFinder/Clone 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 company requires their ESXi server to boot from an EMC Symmetrix VMAX device over the SAN.

What is a consideration?

Access control is being deployed in an EMC Symmetrix environment.

What are the access control rights that need to be given to the Symmetrix Service Processor?

You are provisioning EMC Symmetrix VMAX storage for a large ESXi environment. A request has been made to present 320 LUNs to each of the physical hosts. When you examine the storage configuration on each of the hosts, you are able to see only some of the drives assigned.

What could be causing this issue?

A company has a vSphere environment consisting of eight ESXi hosts. Each host is running EMC PowerPath/VE and is connected to multiple FA ports on their Symmetrix. PowerPath/VE will not claim the disk devices presented by their storage array even though the devices are seen by the hosts.

What is the most likely solution?

A company has decided to change the multi-path policy for all of the disks attached to their ESXi hosts.
The environment consists of 16 ESXi hosts with 84 LUNs connected to each host. Since the multi-path policy is applied at the LUN level, changing the policy is going to prove challenging. Thousands of changes will have to be made which will be time consuming.

What is the best way to make the necessary changes?

When using Performance Manager to analyze an application, you notice that the application has almost no writes but has an extremely high read hit ratio.

Which kind of application does this profile most likely represent?

A company has activated a consistent clone replica of an Oracle database using hot backup mode on February 26th. The Oracle instance continues to run until March 6th. On March 7th, the company realizes that an application problem occurred on February 28th.

What is the most recent point to which the database can be recovered?

A company is evaluating SRDF/Star. They are concerned that the RDF daemon represents a single point of failure.

How could this concern be addressed?

An SRDF/Star user wants to move their workload from the current workload site to one of the target sites.

Which operational step is necessary before executing the symstar halt command?

Refer to the Exhibit.

When Concurrent SRDF/Star is enabled, what is the purpose of the two SDDF sessions at Site B?

Refer to the Exhibit.

A company has three data centers and has decided to protect its data using SRDF. The replication design must ensure there will be no data loss if Site A fails. All data centers are within 200 km of each other.
Either Site B or Site C should be able to take over as production sites in the event of the failure of Site A.

How should SRDF be configured between Sites A and B, and how should devices be configured at Site B?

An EMC Symmetrix VMAX is shared between a company's sales and engineering departments. The company has the following requirements:
1. A specific user from the sales department should be allowed to execute TimeFinder commands on the devices set aside for sales using a Solaris host.
2. The same user should not be allowed control over devices belonging to engineering.
3. No other user with an account on the Solaris host should be able to exercise the same controls specified in the first two requirements.

Which combination of access control permission and user-based authorization role will fulfill this requirement?

A company wants to configure a three-site disaster tolerant SRDF solution. The production site will be at Site A, the nearby target will be at Site B, and the distant target at Site C. The company has large amounts of Symmetrix storage but wants to minimize the cost of network bandwidth.

Which data center solution would you recommend?

Storage administrators for a Symmetrix running Enginuity 5773 need to increase allocated storage for Microsoft Exchange LUNs without interrupting the mail server's operation. Performing a protected striped LUN expansion causes a critical nightly clone operation to run for hours instead of minutes. This impacts later dependent jobs, preventing production operations from completing.

How can this impact to the nightly process be prevented?

All applications running on an EMC Symmetrix VMAX array are experiencing poor performance. The environment is characterized by:

What can be done to guarantee service levels of business critical applications?

Prior to creating your Symmetrix VMAX architecture for SQL, you are given a Perfmon Log view containing data for your database LUN. The file contains read and write IOPS collected over the past week, at 3- minute intervals.

Which method should be used to determine the correct IOPS target for calculating the appropriate number of RAID corrected spindles?

Four DRV devices are configured in an EMC Symmetrix DMX array. As per current settings, a maximum of four simultaneous swaps and eight swaps per day are allowed in the Symmetrix. Optimizer analyzes the back-end I/O and decides to swap.

How many swaps are allowed at the same time?
