Title : Symmetrix Business Continuity Expert Exam for Storage Admins

1. A company has a five-node MSCS cluster running SRDF/CE with three nodes at the primary site and two nodes at the secondary site. The sites are 10 km apart. Due to capacity requirement changes, additional storage is needed.
What must be done to the cluster after the storage configuration changes?
A.No action is required with MSCS after storage provisioning. All storage configuration updates are propagated automatically via the COM server to the cluster nodes.
B.SRDF/CE cluster requires use of the COM server that must be restarted after all configuration changes. Once a change is made to a node configuration, it will send out a message to all other cluster node members after the service restarts.
C.The clusters must be rebooted, and a complete rescan of the system bus is required. Any current patches should be applied at this time.
D.Update the SRDF/CE database by issuing a Symmetrix SRDF/CE Discover through the console or manually setting symcli_db_file to srdfcesymapi.db followed by the symcfg discover command.
Answer: D

2. Your customer requests an immediate point-in-time copy of their production Oracle database but cannot have the application brought down.
Which Enginuity feature allows the creation of restartable copies without quiescing the database?
A.Double Checksum
B.Enginuity Consistency Assist
C.Multi-Session Consistency
D.Symmetrix Differential Data Facility
Answer: B

The diagram shows a planned Star configuration with two Symmetrix arrays at each site. The options file to be used for setting up Star is shown on the left.
RDF Groups 5 and 6 on arrays A1 and A2 connect to arrays B1 and B2.
RDF Groups 15 and 16 on arrays A1 and A2 connect to arrays C1 and C2.
RDF Groups 55 and 56 on arrays B1 and B2 connect to arrays C1 and C2.
Which RDF groups in the configuration should be assigned the name SiteB?
A.5 and 15
B.5 and 6
C.55 and 56
D.6 and 16
Answer: B

4. Your client has 10 large Microsoft Exchange servers. Currently, the backups to tape are not completing in the backup window. The database cannot be stopped, and the client has no capacity to increase the number of tape drives available.
How will you help solve the clients problem and provide the shortest possible backup window?
A.Add local BCVs to the Exchange Server disk and use TF/EIM to perform parallel backups.
B.Replicate the data to a disaster recovery site and use TF/SIM to perform tape backups.
C.Use TF/EIM to perform parallel backups directly to tape.
D.Use the EMC EDM product to call the Microsoft Exchange Online Backup API to back up the data to tape.
Answer: A

5. A customer has a 5 (five) node Microsoft cluster (MSCS) that spans across 2 (two) sites over a SRDF/A link. Site A, the primary site, contains 3 (three) nodes. Site B, the remote site, contains 2 (two) nodes. If the customer is using SRDF/CE with Majority Note Set (MNS), what happens to the nodes at Site A if communication is lost between the 2 (two) sites?
A.Nodes at Site A and Site B will go offline until communication resumes to Site B. The nodes at both sites need to be started manually, and the /ForceQuorum switch must be used.
B.Nodes at Site A will go offline until communication resumes to Site B. The nodes at Site A need to be started manually and the /ForceQuorum switch must be used.
C.Nodes at Site A will go offline until the nodes at Site A are manually started and the /ForceQuorum switch is used.
D.Nodes will remain online.
Answer: D

6. Click the Exhibit button.
During the design process of a Star implementation, a customer expresses the intention to switch production to one of the target sites as part of a disaster drill. After the production has been switched, the customer wishes to run Star protection at this site.
What should you advise?
A.It does not matter which site the customer switches production to, because Star protection cannot be enabled when the workload is running at a target site.
B.Servers and management hosts may be provided at either site, because Star protection can be enabled while the workload is running at either target site.
C.Servers and management hosts should be provided at site B, because Star protection can only be enabled if the workload is switched to the Synchronous target site.
D.Servers and management hosts should be provided at site C, because Star protection can only be enabled if the workload is switched to the Asynchronous target site.
Answer: C

7. A customer running SRDF/Star experienced a workload site failure. Production was switched from the workload site A to the synchronous target site B. Some time later, site A came back online. Before switching production back to site A, a symdev show command is executed to examine the R1 devices at site A.
What is the RDF configuration state that describes the relationship of the RDF devices between A and B?
A.Duplicate
B.Half
C.Normal
D.Partitioned
Answer: A

8. Click on the Exhibit.
In an SRDF/Star implementation, the Connected state indicates which condition has occurred?
A.Both links are transmitting data, but one or both target sites are not fully synchronized with the workload site
B.The RDF relationship is not properly defined or there is no data flow between the sites.
C.The RDF relationship is properly defined, but the target site in question is not synchronized with the workload site and there is no consistency protection for the remote data.
D.The RDF relationship is properly defined, dependent write consistency of the data at the synchronous target site is assured through RDF-ECA and dependent write consistency at the asynchronous target is assured through MSC.
Answer: A
