Question1: A customer's regulatory requirements are to have valid disk-based data at the recovery site regardless of any equipment or logical failure in the system or environment and have the ability to test recovery non-disruptively.
What is the minimum number of disaster recovery site point-in-time copies required to perform recovery testing?
Response:

Question2: Which statement accurately describes RTO?
Response:

Question3: A customer is using ShadowImage(SI) on a Virtual Storage Platform (VSP) for a point-in-time copy. The SI P-Vol resides in a SAS HDP pool and the SI S-Vol resides in a SATA HDP pool. During resychronization, the VSP cache write pending hits 60 percent utilization in CLPRO.
What are two ways to reduce the resynchronization impact on host performance?
(Choose two.)
Response:

Question4: You want to automate disaster recovery site point-in-time copies. Which tool is commonly used for this task?
Response:

Question5: What are two benefits of using ShadowImage on an HUS 150?
(Choose two.)
Response:

Question6: If write MB/s is unavailable for an application, which three metrics should be used together to determine write throughput?
(Choose three.)
Response:

Question7: A customer plans a 2-day disaster recovery test once a quarter. They use a 4-copy model for replication and have an RPO of 24 hours. Which statement is true?
Response:

Question8: A customer is implementing a single ShadowImagecopy of 10 TB of storage on a VSP. How much storage must be provided for the secondary volumes (S-Vols)?
Response:

Question9: A customer is using 10 GB of a 32 GB non-HDP LDEV. They plan to replicate this data using Hitachi Universal Replicator to a HDP LDEV on a secondary array.
What should the customer consider when planning to replicate to an HDP volume?
Response:

Question10: A customer extends their corporate SAN to a branch office storage array, but they observe that they are not able to fully utilize the bandwidth between their sites. Which configuration would allow them to accomplish this task?
Response:

Question11: A customer is planning to replicate 36 TB of data using asynchronous replication. What are two primary considerations for sizing the expected solution?
(Choose two.)
Response:

Question12: How long is a 2 Gbps Fiber Channel frame in fiber optic cable?
Response:

Question13: What are two HDS recommendations when using channel extenders?
(Choose two.)
Response:

Question14: Which tool will capture write workload data on Linux hosts?
Response:

Question15: A customer needs to make a business case for purchasing ShadowImage for a key database What are two benefits that ShadowImage copies provide?
(Choose two.)
Response:

Question16: A customer is conducting a test and has performed a planned failover to their Hitachi Universal Replicator copies at the secondary site. They have confirmed their recovery capabilities and they are ready to return operations to the production site.
Which fallback procedure applies?
Response:

Question17: Which two factors will affect ShadowImageresync time?
(Choose two.)
Response:

Question18: You want to identify if channel extension products are currently in place. What should you do to obtain the required information?
Response:

Question19: A customer is replicating a database with a five minute RPO between two HUS 150 arrays. They have workload bursts that exceed their available bandwidth.
Which replication technology would meet this requirement?
Response:

Question20: Your customer is determined to conduct disaster recovery testing with the Hitachi Universal Replicator volume in a read/write state at the secondary site. The test will take 4 hours and they have a 4-hour RPO.
Which two impacts will this have on their ability to recover from a disaster?
(Choose two.)
Response:

Question21: Which sizing metric is directly affected by the peak write MB/sec measurement provided by the workload analysis?
Response:

Question22: Which two workload measurements are used to calculate bandwidth requirements for replication?
(Choose two.)
Response:

Question23: A customer has TrueCopy with a single cascaded remote ShadowImage solution that they resynchronize every two hours. The customer requires disaster recovery testing to be nondisruptive to production and the replication cycle.
What should be considered while planning a disaster recovery test?
Response:

Question24: A customer has a peak rolling average of 100 MB/s. They would like to preserve write order fidelity for up to 1 hour in their Hitachi Universal Replicator environment. What should be the size of their journal group?
Response:

Question25: How do you separate TrueCopy and Hitachi Universal Replicator traffic running between two VSPs?
Response:

Question26: On a Virtual Storage Platform, a customer wants to create a daily in-system replication copy of a database. They want to retain each copy for 90 days. Which product is required?
Response:
