Answer: AD

3. What are two risks when extending a production SAN over distance? (Choose two.)
A.A telecommunications outage will segment the fabric.
B.RSCN storms may ensue from intermittent telecommunications issues.
C.Any differences in domain IDs on the fabric switches between the sites will keep the fabrics from merging.

4. Which formula is appropriate to use when calculating resource requirements for TrueCopy Asynchronous?
A.Bandwidth = [(peak write Mb/sec) / network compression ratio] + safety margin
B.Journal Capacity = (peak write Mb/sec) * anticipated network outage duration (minimum of 6 GB)
C.Number of RAID groups for journal volumes = (peak write Mb/sec) / (total throughput per RAID group)
D.Host delay = 2 * [(distance between MCU and RCU) / (speed of light in glass)] + losses due to network overhead
Answer: A

5. A customer is using TrueCopy Asynchronous to continuously replicate a database's data and log volumes.
Which two statements are true? (Choose two.)
A.A database checkpoint should be forced immediately upon failover.
B.In the case of a planned outage, log volumes may not include all transactions.
C.In the case of an unplanned outage, log volumes may not include all transactions.
D.At recovery time, the database will rollback all uncommitted transactions in the logs.
Answer: CD

6. A customer is using TrueCopy to replicate a database's data and log volumes.
Which strategy will assist the customer with recovery from logical corruption such as a mistakenly dropped table?
A.Use ShadowImage to create point-in-time copies for recovery.
B.Use TrueCopy for data volumes only. Use log shipping to transfer individual transactions to the recovery facility.
C.Manage database checkpointing so that logs retain sufficient transactions to allow playback up to the corruption event.
D.Inflow control should be used to throttle incoming write traffic so that updates can be identified and prevented prior to their application onto the secondary volumes.
Answer: A

7. Which is required for I/O consistent recoverability?
A.Clustering software is in use at the recovery facility.
B.Recovery volumes have preserved write order fidelity.
C.Buffers on production hosts were fully de-staged to physical disk.
D.Log shipping is used to transfer transactions to the recovery facility.
Answer: B

8. What are three regulatory requirements pertaining to data retention? (Choose three.)
A.Basel II
B.ISO 9000
C.SEC rule 17a
D.Email Archiving
E.Sarbanes-Oxley Act
Answer: ACE

9. Basel II is the second Basel Accord and represents recommendations by bank supervisors and central bankers from 13 countries making up the Basel Committee on banking supervision to revise the international standards for measuring the adequacy of a bank's capital.
Which three statements are true for Basel II? (Choose three.)
A.It can easily be circumvented by regulatory arbitrage.
B.It ensures that capital allocation is less risk conscious.
C.It ensures that capital allocation is more risk conscious.
D.It separates operational risk from credit risk, and quantifies both.
E.It attempts to align economic and regulatory capital more closely to reduce the scope for regulatory arbitrage.
Answer: CDE

10. Which two statements are true for RPO? (Choose two.)
A.If the recovery point is within hours, no replication is necessary.
B.If the recovery point is within minutes, asynchronous (or off-line) replication may be suitable.
C.If the recovery point of an application is set to within seconds of a disaster occurring, synchronous (or live) replication (duplication) of data should be considered.
D.Global clustering, manual migration or tape restore are various options that are dependent on the acceptable time scales required to restore systems to full operations.
Answer: BC

11. Which statement describes RPO?
A.The point-in-time to which data must be copied to start tape backups.
B.The point-in-time to which data must be restored in order to start backup operations.
C.The point-in-time to which data must be restored in order to resume processing transactions.
D.The point-in-time to which data must be archived in order to resume processing transactions.
Answer: C

12. A RPO of six hours has been defined.
Which two statements are true of the selected RPO? (Choose two.)
A.Backups or other data copies must be made at least every six hours.
B.Systems must be restored to the state they were in no longer than six hours ago.
C.RPO defines the environment's ability to withstand major disruptions to systems and related business processes.
D.A complete system restore is necessary including system and boot partitions, system settings, applications, and data to their original state at some point prior to a disaster.
Answer: AB

13. What is the main difference between RPO and RTO?

B.The RPO focuses on how much downtime is acceptable, while the RTO focuses on how much outdated data an organization can tolerate.
C.The RPO focuses on how much backup time is acceptable, while the RTO focuses on how much outdated data an organization can tolerate.
